Having problems with your Acer Aspire L100 PC Desktop ?

Computer shuts down for no discernable reason

\015 I have an Acer that I recently moved from my office to my home. It shuts down completely (like it is losing power) on its own. The monitor is connected to the same power source and it keeps running. I have taped the power cord into the back of the computer but this didn't help. The shut down usually happens within 30 minutes of firing the computer up but it can be a few minutes or over an hour.\015

Wow........wish i would have found this site a week ago. i have been working on one of these acer L100's for a relative and these are some things i have discovered.
\015\0121-the connection on the back of the CD drive is week. if it lose its connection , the computer imediately shuts of.
\015\0122=heat management is controled by advanced power controls related to temp sensors fan speed and poprocessor voltages. if the bios, cmos or os power management is not working properly lots of weird things happen to the computer like inconsistent boots, graphics glithes and failures and just plain old overheating because the smart fan does not ramp up the fan whenever it gets hot or is using more power.
\015\012 i was able to fix this one by resetting the cmos. you do this by unplugging the power and removing the 3 volt battery on the motherboard. unfortunately it requires quite a bit of disassembly like changing the cards.
\015\012 i plan on looking for other solutions like flashing the bios or a way of resetting it in the operating system.
\015\012 i hope this is some good info and another suggestion is bios updating. i finally found some info on that at acer, but still do not know if this version has an update.

I've had the same problem with mine since day 1. what happens is when the amd processor heats to 90 degrees celcius, it shuts off. this is the highest temp setting in the bios. to fix the problem i went into the bios and disabled the variable fan speed setting. now the fans run at full speed and the processor stays around 50 degrees celcius. the problem now is fan noise! thanks acer!
