Hi, prashanth.  Welcome to LandzDown Forum.

I have a few ideas, but not necessarily a solution to your problem:

• There may be a problem with your power supply (charger).  If you know someone who has a compatible device, you could test to see if the problem still occurs.
• Does the same thing happen if you attempt to start the laptop in safe mode (with or without networking) while using the power supply?
• You could also try removing the battery and attempting to power on using only the power supply.
• Another possibility is overheating.  You can download Speed Fan from http://www.almico.com/speedfan.php .  Compare the temperature while on battery to connected to the power supply.  The laptop may need careful cleaning.  See the section on laptops at How to clean a computer.

Let us know how you make out.

When I was researching your problem, I surprisingly discovered that a number of people had the same issue -- and with different vendor laptops so not necessarily a Toshiba issue.

Have you tried cleaning the laptop of any collected dust?

Hi, prashanth.

From what I have seen when researching this, it does appear that there may be a hardware problem.  You could try the Microsoft Online Crash Analysis:

The Windows Memory Diagnostic tests the Random Access Memory (RAM) on your computer for errors. The diagnostic includes a comprehensive set of memory tests. If you are experiencing problems while running Windows, you can use the diagnostic to determine whether the problems are caused by failing hardware, such as RAM or the memory system of your motherboard. Windows Memory Diagnostic is designed to be easy and fast. On most configurations, you can download the diagnostic, read the documentation, run the test and complete the first test pass in less than 30 minutes.

To run Windows Memory Diagnostic, you must reboot your computer with the disk or CD-ROM on which you installed Windows Memory Diagnostic in the drive. After the reboot, Windows Memory Diagnostic will load and its interface will appear. After loading, the first test pass will begin, using the default standard test suite, and continue until complete, unless Windows Memory Diagnostic is either paused or exited. Once the first test pass is complete, Windows Memory Diagnostic will begin a second test pass using the same settings as before. Windows Memory Diagnostic will continue to run test passes until you exit.
