The other day when i went to turn my CQ56 laptop on, it wouldnt boot, just black screen with flashing Caps Lck light indicating CPU failure, but after maybe about 100 times of on and off it eventually booted up and operates normally. If it goes to sleep or hibernate or shut down, it wont boot up again and have to repeat the on-off process multiple times. If the motherboard is bad, will it cause the intermittent boot up or can it be a power supply issure or what? Once its up and running, the speed is fine and no warning messages or anything. I tried formatting the HD, holding power button for 30+ sec w/ battery out, removed and reinserted RAM and HD. Still does the same thing. This is a Win 7 o/s, Compaq presario CQ56 less than a yr and a half old. Find it hard to believe the mobo went bad already. Thanks for any kind of suggestions.

What are the temperatures like where you are, can you hear the CPU fan working when this happens.

Check the condition of the battery as in the ability to hold a charge http://h20000.www2.h...ectID=c00821536
