Edit: Fixed! see solution here by user xavier60Hey there,
A neighbour asked me to have a look at his
Acer 8930G series laptop (model 8930G-844G32Bn). The laptop is still useful, and they'd like to be able to recover some files from the PC's HDD.
Initially the problem was that it didn't charge : removing one screw revealed the problem was the wire to the PSU connector was broken (stupide design idea : the barrel connector twists when the laptop screen is opened). It looks like a common failure un this model. I fixed the wire, the laptop is now powered.
Now the problem is that the laptop won't stay on for more than a few dozen seconds. Since the first try, it turned on, Windows started its repair process thing, and the PC would restart.
I checked the BIOS, set thing to default, removed the battery, and tried again : same thing, the laptop keeps restarting after a few dozen seconds (sometimes before).
I then tried with a live Ubunbtu USB drive, even after disconnecting the HDD, same thing.
I removed every thing I could (USB ports PCB, PCI slot, Optical disk drive, WiFi module, etc.) and the only thing remaining were the screen, the power button, the keyboard and the power adapter. I checked with either RAM modules. Same thing. The copper heat pipe is not that hot : I can keep my finger on it, so I guess it's under around 55°C. Still I replaced the thermal paste.
A weird thing : If I open the BIOS menu, it doesn't restart on its own.
TLDR: laptop restarts after a few dozen seconds on its own.
What could be the problem? What should I check?
Thanks!
