Hello all,
Recently I picked up a Gateway KAV60 off ebay that was listed for parts because I was confident it would be fine since I've had good luck recently with systems being listed for parts that actually worked fine. Anyway, this laptop arrived with no battery and no charger, but I already had a charger of my own. Upon powering on this laptop the power light comes on, the screen stays black, the fan spins up for about 3 seconds, the machine stays on for about 5, then it shuts off. If i try to power it on without the ram installed it does the same steps but just stays on instead. Removing the wireless cards seemed to have no affect on the behavior of the laptop the addition or removal of ram caused the 2 states. I tried different known good ram sticks and the same results were produced. I thought maybe it would be a dead cmos battery issue, and I was partially right, the CMOS battery read 1.4V instead of the usual 3. So this morning I replaced the CMOS battery, with a socket and new battery, since the old one was soldered directly. After checking for shorts and finding none I got it put all back together and it is behaving exactly the same. I read some forums online that most likley this is just a dead board or has a dead graphics chip but I want to see if anyone else has any input on what might be causing this. Any thoughts or ideas are appreciated.
Note: I have also tried extrenal display and get no picture; this unit also did not come with a hard drive.
 
Solution
As of a couple days ago I got a new old stock board in and removed the battery and added my own and this fixed the issue. It seems it was in fact a dead board.

Thanks for the recommendation. I did actually remove the heatsink too during my first teardown and reapply paste to the gpu and cpu. This unfortunately didn't change anything.
Update: at this point I have also managed to power up the board outside the case, unplugged from the daughter usb/audio/sd card board and with no keyboard or monitor attached using only power connector, power switch connector, and external display cable and the same exact results are produced ruling out the chassis and parts for any source of issue. I’m really guessing is the motherboard :/
