I tried to ask this question before and the topic essentially died. So now with new information, I'm going to attempt this again.
My buddy sent me his Acer 7750G laptop after a book fell on his laptop and broke the screen. Replaced the screen and went to boot up the system and it'd power on for 3-5 seconds and then turn off. At no point in time would it ever reach POST. In the time the system was on, you'd hear the fan spin and the click of the hard drive trying to spin up. When connected to AC, this on and off cycle would occur about 5 times. On battery, it'll only attempt it once.
Now I've tried removing the CMOS battery and replaced it with a new one. I've also attempted to remove the RAM and use one stick at a time. I've tried removing the hard drive and still no luck. The person helping me before had me try a few other things as well such as using an external monitor with no change. That lead us to believe something was wrong with the motherboard.
At the advice of someone else, I decided to check the processor and motherboard for any signs of a short, blown capacitors or any other damage. I didn't see anything, but I know motherboards are very delicate and whatever issue there could be might be microscopic. One thing I did notice though was the thermal paste on the video chipset was hard and crusty. Before I take the plunge on recommending a new motherboard to my friend, I was curious if the issue I'm seeing is purely one of overheating.
Is there any other things I should try to attempt before recommending a new motherboard? Thanks for reading.
