Welcome to the HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I came across your post and wanted to assist you.
If Windows suddenly restarts without warning, or restarts when you try to shut it down, it might be caused by one of the several issues. Windows could be set to restart automatically when certain system errors occur. A BIOS update can also resolve the issue. Use the information in this document to resolve issues with the computer restarting unexpectedly.
If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue:
1. Examine the adapter and power cord for physical damage
2. Test the power from the AC wall outlet to the notebook connector
3. Start computer using the battery only
4. Check that the lid switch moves freely
5. When you have completed the troubleshooting steps covered in this document, there should be power available to the computer. When you press the power button, the LEDs should glow, and you should hear the sounds of the fan and the hard drive spinning.
* If the battery does not accept the charge or the notebook does not turn on without the AC adapter, contact HP to order a replacement battery.
* If the LEDs do not glow, and there are no other indicators of power being available to the computer, contact HP for technical assistance in troubleshooting a potential problem with the AC power connection or the system board.
Here is the list of documents which should help to resolve this issue:
