I have an Acer Aspire 5102 that has been back to acer service 4 times during its 3 year warranty peeiod. they said they have replaced the hd and MB along with the hinges on the screen. My opinion is it is a lemon but Acer was fixing it so I had no problem except I had to keep returning it.
My current problem is that it has developed a problem that I can't figure out. After using it for 45-60 minutes (the air leaving the case is HOT) if I turn it off and restart it, it reloads wndows and everything is fine, but if I turn it off for say 2-3 hours and try and start it up themachine boosts Bios and the HD light goes solid and I hear a beep and I get a BS that says I have error 200 and the my fixed drive is defective. It is wrong. I just replaced the HD with a new one that match's spec of the original. I have re-installed the upgraded bios (V3.13) and it should be aok, but it is not.
Does anyone on the forum know if a defective motherboard will cause these symptoms? it is driving me nuts and Acer Tech basically tells you to drop dead after the warranty expires. I don't want to have to replace this computer as I only use it for occasional computing. All told, it probably doesn't have 100 hours of actual useage. I spend most of my time trying to get it to just work properly.
Any comments would be appreciated.

sounds like a bad mainboard. try pressing firmly with your pal just to the left of the touchpad. then turn the unit on and see if it works. it may work, if it does don't move the laptop or it will probably fail again.

one of the chips on the mainboard is probably loose or going bad.
