I've got an issue going on with my notebook PC. For a couple of months now I've been experiencing random shutdowns on my PC.

It all started when my previous power adapter got fried. Nothing really happened, the cord just melted through in the place where it goes out of the black box, a common issue.

I replaced it with a new adapter, not an original one, though. So it had a slightly loose plug. Sometimes I lost power when moved the PC too much. There's no battery inside, so power intterruption turned it all off. I fixed this replacing the faulty plug. But the PC shuts down from time to time.

It happens usually when I'm working with it. It never happened when I left it to download something over a whole day or a whole night. Some days it doesn't happen. Some days it happens twice within an hour and then nothing. On other days, from time to time I suffer from a shutdown.

There is no warning on the part of the system, no freeze, no system log message (apparently), it just dies.

What may be the issue and how to diagnose such a thing? ? ?

EDIT: Could it be a mechanical issue? Like a broken solder? After all, it's a "mobile" device.

You state that it happens when you are "working with it".

What types of things are you doing with it, exactly, when it shuts down? I'd suspect and rule out overheating first, but it's hard to advise without knowing what types of things you are doing.

I've not dealt with Acer in years. Perhaps the next time it shuts down you can check the bios to see if there's a thermal sensor/reading. If you can open it up... maybe you can make sure the heat sinks are snug, etc.

You could also use some of the OS/thermal tools like this, for example.

  • Have u tried re-installing your OS , it could be a OS problem too.

  • If the processor overheats then some motherboards shut the system automatically

  • If the problem persists it could be a hardware problem related to your SMPS, motherboard, or sometimes Hard-Disk.

I had a similar problem like this, my SATA cable connecting the primary Windows Loaded Hard-Disk was loose.

Anything is possible. But if it turns itself off, could be a few things, do you get any error messages when it starts up? This would indicate a type of error usually with the hardware. Does it blow very warm air out of the vents, this would indicate a problem with cooling, a hardware cooler could do the trick. Otherwise make sure no programs are stuck in memory causing the machine to work extra hard, specially with programs that test Internet connection like iplogger or some other type of monitoring software. Other thing, is keep your security and critical updates up to date, with the latest recommended updates, but not for the 3rd party type. One other thing to test out if none of that works, is run a test with a Live-CD, other than Ubuntu like PCLinuxOS to see if you get the same results. Maybe it is just an incompatibility issue.
