Power/Boot problems on Acer Aspire 5735
Posted on 2010-11-16
I'm currently using an Acer Aspire 5735 laptop, and am experiencing some power/boot problems to it.
If I plug a power adaptor in, the machine turns on automatically (it should wait until I turn the machine on) and for a battery it works as normal. If I power on, the machine starts (Motherboard LEDs come on) and the fan starts to spin up, and after about 10-15 seconds it shuts off again. If it's plugged in, a few seconds later it will start this process again.
I've tried it with just power, just battery and using both and each time it gives the same results. I've opened it up and removed components one by one, til I'm just left with the motherboard on its own and judging by the LEDs it's doing the same thing as before - powering up then shutting off a short time later.
Through process of elimination, it's got to be a problem with either the motherboard or the PSU, surely? I'm fairly confident it's not the plug itself, since it behaves exactly the same with the battery. Looking over the motherboard I can't find any signs of obvious damage (none of the cylindrical things on the motherboard are bulging or burst like one site recommended to look out for).
Is there any way to find out where this problem is coming from?
