Samsung N128 Mini Laptop Review

It is working great than I expected. First I failed to find WiFi adapter driver compatible with Windows 7. The setup disc has only Windows XP version of Wireless adapter driver. I downloaded the latest version of wireless adapter driver from manufacturer website. I must say, speaker volume is lesser than I expected. It has 1.5 watts Speaker. The volume is very low and I need to use headset to hear the sound properly. Another point I want to point out is about battery backup. Shop owner promised me about 8 hour battery backup but when I check it is just 6 hours only. Beside this speaker volume issue, I am satisfied with Samsung N 128 netbook.

Have you ever thought about the location where System Restore points are stored on a computer? System Volume Information Folder stores system restore points on your computer and helps you to recover previous setting on your computer in difficult times. One important fact about it is its high security and even the user with Administrator privilege cannot take the ownership of the folder directly and open it. Do you want to open it and check how it looks like ? Though we cannot do it in straight methods, there is always some backdoor method to perform it. This tutorial explains the steps to open System Volume Information folder by taking ownership of it.

It is because if the user has the privilege to sensitive features, any possible infections on that user account can infect them. If any other user is having access to this account, it might even worse the situation. It is not a wise decision to configure this feature in a way to open for anyone who use the account.

My Computer Restarts Automatically - Reasons & Solution

We have discussed many hardware related issues on this blog. This tutorial tells one of the common computer issues, unexpected automatic restarting of a computer. Once I faced this situation where my computer rebooted automatically without providing any warning and I lost every unsaved works. For a week this issue continued and at last I fixed. I believe having a guide for those who face the same problem can be very helpful to identify the reasons for the automatic restarting of their systems. If you can identify why your PC is rebooting suddenly without warning, you will be able to solve it very easily.

Reasons for Unexpected Automatic Reboot of Your Computer

Here we check common reasons for the issue. Some of them are software conflicts, hardware issues and virus infection. Let us check carefully why should a computer restart without giving any warning.

  1. Software /Driver Conflicts

    When your PC acts strange, first verify the last installed software or driver on your computer has no compatibility issues. After installing new software or driver on your PC, if it has any compatibility issues, you may face this issue. If you think the automatic rebooting issue started after installing any new software, you need to uninstall the software from your PC either by add/remove programs or by the built in software removal utility. If the issue persists even after uninstalling the software, you can perform a system restore to a date before the day when the driver was installed.

    1. Uninstall the recently installed software

    2. Perform system restore to an old date

  2. Hardware Issues

    If there are no software compatibility issues on your system, you may check for possible hardware issues. Here is a list of potential hardware problems that can make your PC restarts automatically.

    • Heat related issues

    • Corrupted system memory

      If the RAM modules in your PC are corrupted, that may cause automatic system reboot. To verify it you should start your PC with another piece of RAM and check for the issue.

    • Dust particles in your system cabinet

      Presence of dust particles in CPU may trigger automatic system restart. It is a good practice to clean system cabinet to make your PC free from dust particles.

By default Windows set automatic system reboot on every system failure. Though this option is for preventing further damages on your system, it is really frustrating to see unwanted system reboot for smaller issues. It is better you have the control to reboot your computer instead of automatic reboot by your computer without your permission. In case if you want to disable automatic system reboot on system failure set on your computer, you can disable it under Startup and Recovery. You will see a checkbox to stop Automatic Reboot on Startup and Recovery settings window.

Google warns us, using incognito will not make us secure from other Internet threats. It cannot protect our data from websites which collect information from our computer by installing malicious codes. Agents who work with ISP can track our Internet activities unless we encrypt the entire communication. Incognito is also helpless against Malicious software products like Trojans or keyloggers if they are already installed on computers. Keylogging tools can track every keystrokes we make on a PC and either store the details or send to its server. Private browsing feature of a browser cannot prevent this activity. However, we can prevent the auto saving of cookies and browsing history on our laptop using incognito feature. Even the the download activities will not be entered to the download log file. In a nutshell, though this feature will not give anonymity of full safety, it is worth than browsing using normal browser window.

No SSID Broadcast From Wireless Router & Access Point

Yesterday night I faced a strange issue related to wireless connectivity on my laptop. I could not find SSID from my router. First I thought it was my Laptop wireless adapter's issue as there are no other networks. My desktop does not have wireless adapter so I have no other option to verify whether it is the router issue or my laptop issue. Today morning I went to one of my friends house and checked whether my laptop is able to see WiFi from his Access Point. Yes, my laptop is seeing it from his Access Point. So it is clear that my laptop adapter is working fine and the culprit is my Wireless Router. The major steps I performed on my router to fix this issue are described below in a systematic order.

Router is Not Broadcasting Signal

Step by step troubleshooting for a Router or Access Point when it is not broadcasting signal.
  1. Check WiFi light

    Check the status of wireless light on the AP. If it is broadcasting WiFi, the light is ON. If it is off, you cannot see WiFi network from AP on your computer because there is no broadcast. In some rare cases, this light may be off even though it is broadcasting signal due to LED issues. Here I assume LED light is fine.

  2. Make sure the SSID broadcast is enabled

    To check this, you need to log on to setup page and check the status of SSID broadcast. You can find this option under wireless tab. If SSID broadcast is disabled, it will not broadcast WiFi.

  3. Power cycle

    It is advised to power cycle Access Point to fix broadcasting issues. To perform this you should power off the device for 30 seconds and after 30 seconds power on it again. When all the lights are steady, check for the issue. If you do not know how to perform it in systematic way, follow the instructions provided in the link below.
    How to Power Cycle an Access Point

  4. Change SSID

    It is advised to change the wireless network name (SSID) and check whether your laptop is receiving signal. You can change the current network name under wireless.

  5. Change wireless channel

    You can change the wireless channel to channel 1 ,6 and 11 depends on the current channel. To learn more about it, visit the link below.
    Change WiFi Channels on Linksys Access Point

  6. Upgrade Firmware

    If the firmware flashed on your Access Point is outdated you may start seeing issues with its working. Updating to latest firmware version can resolve every known issues and bugs in the previous version. It is highly recommended to update the firmware of any networking device with latest version to expect full functionality.

  7. Reset and reconfigure

    If none of the steps provided here are working, you may reset the device to factory default and reconfigure it.

All the steps above mentioned are about how to troubleshoot the router when there is no broadcasting from your WiFi router. What if the real culprit is your laptop and not the router ? In that case you should troubleshoot the laptop instead of router. You can follow the instructions provided in the link below in that case.

Dr.Watson Postmortem Debugger has Encountered a Problem and Need to Close

Yesterday night while working on my computer I saw the error message "Dr.Watson Postmortem Debugger has encountered a Problem and need to close. We are sorry for the inconvenience." My computer froze when I pressed 'don't send report' button. Since I couldn't work anymore, I restarted it but again the same Dr Watson Postmortem Debugger came up with a sorry message. I was unable to do anything on the desktop PC and I started browse on my Laptop. First thing I did was a search using the error message and found many people were facing the same issue. There are different opinions about the error message varies from system error to possible malware attack. While surfing more, I found it was not a malware but a built in Windows debugger program. Microsoft is using Dr Watson Postmortem Debugger to collect error reports from devices which use their Operating systems.

How to Fix Dr.Watson Postmortem Debugger Error Message

As I expected, it is not an essential tool for a user. We can either delete or disable it without affecting the functionality of our computers. So I decided to disable this program to make my desktop PC work again. I tried to log on to my Desktop computer and successfully log on to the Windows account after a few unsuccessful attempts. Then I followed the steps below.

How to disable Dr Watson Postmortem Debugger
  1. Click on start

  2. Click on Run and type drwtsn32 on run window and Click on OK. Now the Dr Watson Postmortem Debugger options window will open. It look like the image below.

  3. Uncheck all the check boxes under options and click OK.

Where Can I read Dr Watson Postmortem Debugger Log Files ?

As I explained before, it is a default unnecessary program installed by Microsoft to collect information regarding software errors or bugs. It keeps a log file which stores all software errors happened and send it to Microsoft. Log file crated by Dr Watson Postmortem Debugger records all kinds of software errors that occurs and to read this log file, you may navigate to following location.

C:\Documents and Settings\All Users\Application Data\Microsoft\DrWatson

It is saved in the name drwtsn32 and can be opened in a notepad. This log file contains Application exception occurred, System Information, Task List etc... We can change the log file path of Dr Watson Postmortem Debugger by accessing it by following the steps below.
  1. Click Start,and go to Run.

  2. Type drwtsn32 on Run and press OK.

    What is

    In this window, you can change current settings including log file location. You can specify a different address for log file if you want to change the current path.

Since it is an error reporting tool from Microsoft, you will get the error message "Dr.Watson Postmortem Debugger has encountered a Problem and need to close. We are sorry for the inconvenience" when a program crash. It is not because of virus infection but a feature (unnecessary though) is doing its duty only in an annoying way. Now let us check some other interesting Microsoft tutorials below.

Communication between two APIPA computers without DHCP Server

On the last Saturday Me and my friend are trying to connect two computers directly using a USB cable and start communication between these two computers without the help of any external DHCP server. As I mentioned in my previous post we cannot use ordinary USB cable to connect two computers directly. It may burn the USB port.

[ To know more about it please follow the link below.

http://www.corenetworkz.com/2009/10/can-i-connect-two-computers-using-usb.html ]

In this project we avoid using router or any other DHCP servers. As we are not using the Ethernet adapters we cannot set any static IP address. So without the presence of external DHCP server and static IP address our both computers will get APIPA from Windows Operating System.

[ To know more about APIPA please click on the link below.

http://www.corenetworkz.com/2008/02/how-to-resolve-issue-when-ip-getting-is.html ]

So the IP address our computers got was 169.254.X.X range. Fortunately the IP address gained by our computers were in the range 169.254.1.X and it started to communicate with each other.

It is sure that APIPA computers can communicate each other as their subnet mask is (Class B address). So as the subnet rules says the network address of APIPA is and the broadcast address is Any address comes in between these range can communicate each other. Because it is a private IP address we cannot use APIPA to get Internet connection to our computers. For Local networks and Intranet APIPA is enough.


When to Charge Laptop Battery & Increase Battery life and Efficiency

When it comes to laptop battery charging, there are different opinions about the right way and time to do it. This tutorial explains how to manage a laptop battery with right time to recharge and steps to keep remaining charge more efficiently. Lithium based battery is used for laptops and it is better wait till its charge comes between 20% to 10% to plug it back to power. Most of the experts recommend, never let the battery charge drops below 10% before connecting it back to power supply. In addition to the level of power left, temperature has a major role in the efficiency of  lithium battery.

The better ways to Charge Laptop Battery

Now a days we are using lithium-ion batteries for Laptops and they are having a rapid-charging option. It is important to note that when we start using the Laptop for the first time, it is advised to charge it for a long time (attain 100%). To know the exact time period, better refer the Laptop user manual. Never operate your Laptop at higher as well as lower temperature and keep it in room temperature. So the major points to remember while charging laptop batteries are provided below.
  1. Connect to power when charge falls below 20%

  2. Stop avoiding overheating and better keep in room temperature

  3. For first time use, recharge the battery to 100%

It is better remove the battery from the Laptop if you are not going to use it for a long time. Another important point we need to remember is never short circuit terminals to discharge battery charge. You can configure the time when the power left falls below 20% from power options. To perform it, visit the link below.
How to Change Critical Level And Get Informed

Use Laptop Battery Efficiently

Now we know the right time to connect a laptop back to power. This section covers how to utilize the  battery charge in a better and efficient way. Think of a situation where you are in no position to find a power outlet to connect but wants to continue your work. So the only option left is to manage the existing charge more efficiently. In such a scenario, the following tips will help you.
  1. Turn off Wireless and Bluetooth

    If the WiFi button is on, it will take additional power to scan available wireless networks present in that area. If it fails to find any wireless network, it will continue the scanning. It is same for Bluetooth also. To avoid such a wastage of energy, I recommend you to turn off Wireless button.

  2. Avoid playing computer games

    High end PC games costs too much energy and it not not recommended to play them when you have no chance to find a power supply. Playing games on your Laptop drain laptop battery fast.

  3. Reduce the Laptop Speaker Volume and don't play any movies

  4. Reduce screen brightness

  5. Avoid using external devices like external mouse, DVD drive, USB adapters etc

Can I connect two Computers using USB cable

There are so many methods to connect two different computers and share data between them. Ethernet cables and wireless (IEE802.11 standards) are the most popular modes to connect two devices. However, you can use USB (Universal Serial Bus) cable to connect two computers and use the same connection to share files between them. Though, for this you must use a special type of cable called Bridged USB cable. If you use normal USB cord to connect two computers, it may damage the ports. This guide explains the difference between bridged and normal USB cables.

Connecting Two PCs Using Bridged USB Cable

The type of Universal Serial Bus cable which is used to connect two computers directly is called Bridged USB cable. It is available in two different standards. They are USB 1.1 and 2.0. The difference of standard is based on the speed of data transfer. In 1.1 version, the data transfer speed is 12 Mbps and that in version 2.0 is 480 Mbps. It is very important to note that no other Universal Serial Bus cords are designed for the purpose of connecting two PCs directly. Using wrong cords may harm the USB ports of your computers.

Modes of working of Bridge Cord

The bridged Universal Serial Bus cord works in two different modes. They are:
  1. Link mode

  2. Network Mode

In link mode, two laptops are connected through the bridged Universal Serial Bus cord and the file sharing is enabled. In network mode multiple PCs are connected and Internet too shared in addition to the file sharing. This is the basic difference between link mode and network mode.

How to change system date and time in Ubuntu Linux

This week end was very interesting for me as me and my friends established a Local Area Network in their home. They have total six computers and two of them is running on Ubuntu Linux. After establishing the Local Area Network we implemented one propitiatory real time simulation software on this LAN by installing the software on all this computers. But the software works fine with the integrated data of from 5 computers and one computer is not connecting to it or connection rejects. So the techie in our mind got up and we start troubleshoot the issue.

At first we thought the issue is with the compatibility issue of Ubuntu and the software. But the first Ubuntu computer is working fine with the software and in careful analysis it is found that that computer is functioning more efficiently than other Windows based computers. So it is not the issue with Ubuntu. Then we confused what is the actual cause of the issue. Then I just checked the connection manager of the software and the error message was some thing like unpredictable date with many hexa decimal codes. So it has some thing with system date. We went to the non-functional computer and checked the system date. It was the default system date set when they installed Ubuntu in this. So we just set the system date and time with current date and time . The result was great the issue fixed. So here I am presenting steps to change computer date and time in Ubuntu linux when there is no date and time displays on system tray.

How to change system date and time in Ubuntu Linux

To change the system date and time in Ubuntu Linux from Administration is:

1. Click on system

2. Select Administration and go to Time and Date

3. Unlock Time and Date and enter password.

Now you can change the system time and date by changing the default settings there.

How to Prevent Copying Files to USB Drive From Computer Without Disable USB Port

Today early morning one of my friends called me for an urgent help. He is working as a System Administrator for a small company and wants to disable copying files from working computer to USB drives (pen drives). I told him to disable the USB port and fix the issue. Then he said according to the company policy he cannot disable it. He wants the computer should read files from the USB drive but no file transfer to it from computer hard disk. So in a nutshell he wants to read files from the portable storage drive on his company computers but does not want to copy files from his company computer to the USB drive. He is in a confusion that if it is possible to block writing files to the portable memory storage without prevent the PC from reading it.

I too at first confused with this strange company policy. Then I realize, it is very simple to do. We can enable write protection on USB by GP edit or Registry Edit. If Write Protect is enabled on Universal Serial Bus, computer can read files on portable storage but not able to copy content to them from hard disk. It is very simple to enable write protection on USB Ports from registry.

Prevent copying files to USB drive From Hard Disk

This step tells how to enable write protect on USB port from Windows Registry and prevent computer from copying content to portable memory storage from hard disk. This step doesn't hurt your reading ability and your PC can read files in portable storage without any issues. Steps to disable file transfer from hard disk to portable drive are:
  1. Click on start and go to Run (Press Windows and R button together to open run window).

  2. Type regedit on run window and click OK.

    Now the registry editor will be opened.

  3. Before making any changes to Registry, I recommend you to take a backup of current Registry on your computer.
    How to Backup Current Registry On your Computer

  4. Go to the location.

  5. Create a DWORD value called ‘WriteProtect‘ and set it to 1.

    Now onwards your PC will be able to just read the files from eternal memory drive connected to but the drive can no longer copy content from hard disk.

  6. To disable write protect on USB drives change the DWORD to 0.

What is Overclocking and how it reduces the cost of system upgrade

The title of the post is just interesting as it says the importance of overclocking our computer and increase the performance of the system than the manufactures expectations. But before we start overclocking it is better know what actually mean overclocking. Overclocking is the tweaking of your computer and optimize it for better performance. In simple words by overclocking we are utilizing the maximum possible performance of our computer. In case of running applications on our computer which requires more computing power than our computer offered , we should think about overclocking our system. It is always better have a try to improve the performance of our computer than the costly hardware upgrading.

Risks and negative side of overclocking

Overclocking has some negative side too. They are:

1. Warranty issue

By overclocking we are running a computer component at a specification higher than rated by the manufacturer and it may affect the warranty issued by them. In case the device went wrong the vendor may refuse to help us by saying what you did is against the warranty policy.

So it is advised to perform overclocking on old computer if you are not an expert.

2. Processor stability

Overclocking may result system instability. So it is always better check the performance by increasing the rate of speed slowly.

3. Heat generation

Heat generation is an another issue with overclocking. By increasing the performance of the computer equipments the energy consumption will increase. This result over heating.

As a precaution we should daily check the heat sink and cabinet fans and make sure they are working properly.

Even though there are some negative sides I always encourage you to overclock your old computers and increase the performance of the system. Even if you fails it is just a good attempt and will be an asset your tech life.


Disk Boot Failure -Insert System Disk & Unable to Start Computer

I forgot my Laptop password and I can't access my files

Yesterday night my friend called me. His sister just finished her project work on her laptop and to protect the files she changed the password of her Laptop. After changing the password she is not able to log on to her Laptop. It is a Windows XP Laptop and only one user account is there. What she was telling is the Laptop is not accepting her new password and old password. She told me, tomorrow she should present the project in her college and there is no backup files. At first we tried some possible passwords and they were not working. Then I told them to restart the Laptop and when the Laptop start booting press [F8] button. My intention was just to get the default Windows administrator account and hope there wont be any password set. They started booting their computer and get in to the safe mode. They saw the hidden Windows admin account and log on to it[ Thanks to the guy who installed OS on her laptop as there is no password].

[ If you need to enable Windows hidden administrative account on your computer click on the link below.

How to enable and disable Windows default administrator account ]

Then I ask her to find the data files in the stored location. She said it is word file (May be project description but that is non of my business) and not seeing that. I told her to use the search function to find the file but the result was null. Then I asked her where did you saved the files? She said she saved the files on desktop and now no files present. They opened word and try to find the saved files location, but failed to find the files saved on desktop. The I asked her "do you remember the password hint?"

[To know steps to reset the Windows administrator password click on the link below.

She said yes. Then why should we waste our time go to user accounts and reset the password using the password hit. She did that and the password of her user account has removed. Then she restarted her laptop and successfully log on to her account. She was so happy when she was able to find the saved files.

Steps to disable Windows Messenger through Group Policy editor in XP

Update: Microsoft has lifted their support for this product by April 2013 and recommends users to migrate to Skype. Though this tutorial has lost its importance, I am keeping it on CoreNetworkZ with a legacy status due to the volume of traffic this tutorial generated.

This tutorial explains how to disable Microsoft Windows Messenger (WM) on your  XP computer via Group Policy Editor. Before proceeding to the steps to turn off this application, you must learn about it. It is an Instant Message service program designed by Microsoft corporation. Just like popular IP Messenger, this program also helps to send instant messages to another devices in the same network. Though this application is very much useful for people in a LAN, it can disturb single users.

Router Shows Wireless Packet Drops

Yesterday I faced packet loss issues with wireless router in my home. My laptop is successfully connected to the router via wireless but with lesser speed than normal. At first I thought it is because of the slower Internet connection. I tested my desktop computer with modem and find out that Internet is working fine. Since connection to the modem is perfect, I tested the connected to the router. I connected my desktop computer to the router using an Ethernet cable but couldn't find any speed difference. It is working fine but when I switched to WiFi, it is again slow. I repeated the steps on laptop and pin point the reason. Wireless is acting strange and it is the packet losing issue. This article tells how to deal with packet losing issues by explaining the possible solutions. For your information I use WRT54G  from Linksys in home.

Fix Wireless Packet Losing
  1. Power cycle

    We need to unplug the power cable from router and wait for 30 sec. After 30 seconds you can reconnect the power cable. You need to wait until power, wireless and Ethernet lights are ON. Now check for the issue.

  2. Reduce Wireless beacon interval

    If power cycle doesn't fix the  packet drops, it is the time to log on to the settings page and change beacon interval. Beacons frames (actually it is not a packet but frame because IEEE802.11 networks work in data link layer) are frames send periodically to announce the presence of WiFi network with necessary information. You can reduce the default beacon Interval to default -100 in advance wireless settings. Depends on different vendors, the page may be different but always check for advance settings page.

  3. Update Firmware

    If WiFi drops even after reducing the beacons interval, I recommend you to update the firmware of the Access Point/ Router. Do a power cycle after updating the device firmware.

  4. Reset and reconfigure

After performing these steps, check for the issues. If  you are still seeing packet dropping, it is the time to replace it with brand new device. One last possible fix is to replace the old antenna with new one. However, since it is a consumer level product, I suggest you to invest money in new Access Point rather than buying antennas.
