I have an HP LAPTOP and I was on the internet when it suddenly turned off from being overheated as it usually did. I tried to turn it back on and it would start to power up for 3 seconds, then turn off, power up for 3 seconds, and do that cycle about 3-4 times before finally staying on for about a minute then turning off completely. The last time this happened about 2 weeks ago it just finally powered up all the way to windows and worked and this time it hasnt worked yet. I noticed that if i hold down all the keyboard buttons it STAYS on each time for about 20 seconds before turning off. Does anybody KNOW whats wrong? I need to know quick before I need to send it in for repairs because I dont have any money to get it fixed RIGHT now.If your laptop overheats, something is definitely wrong. Also, turning it on as you did immediatly after it overheats rather then LETTING it cool down is also definitely wrong.

I suggest you see if you can have it looked at by a computer store or the point of sale.The latest from HP restated the solution I found earlier on another message board... it worked for me:>> The operation of the battery is mostly controlled by the power

>> 2. This opens the System properties window.
>> 3. Select Hardware tab and click Device Manager.
>> 4. Click "+" beside System devices.
>> 5. Select ACPI Power Button.
>> 6. Right-click the device and select Uninstall.
>> 7. Restart the system.

>> Windows will detect and install the power management on restarting.
or update the bios....
