Hi, I reciently got problem with an acer aspire 5742g. It turns off when trying to boot from cd or usb.
I thought it could be a temperature problem so I read on internet about desoldering the motherboard cmos battery for half an hour and placing it back on. I did that.
I also replaced the thermal compound on both cpu and graphics card.
The laptop stills shutting off. I can access bios with no problem, but if I try to boot from cd or usb it just turns off
I updated the bios from version 1.07 to the latest bios wich is 1.30 succesfully, but the problem persists.
Also, recently, the brightness dropped down and I can´t do a thing to solve that...
I think this is a motherboard problem... Has anyone got an idea of what component of the motherboard could be in bad condition? I´m an electronics student and I usually repair motherboards with visible damage (including smds etc.) but with no visually damaged components I don´t have a clue of what is the component that might be causing this.
Is this a common problem? How is it possible to be able to get in the bios but not boot? Untill I try to boot I´m able to access the bios but after that I have to do a discharge of the laptop to be able to access it. It doesn´t make any sense to me. Does anyone know what could be the issue? I´m lost!
