Question about Acer Aspire L100 PC Desktop
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.
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.
1-the connection on the back of the CD drive is week. if it lose its connection , the computer imediately shuts of.
2=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.
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.
i plan on looking for other solutions like flashing the bios or a way of resetting it in the operating system.
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!

I've had the same problem with the computer shutting down randomly. It started about 6-9 months after I bought it. I thought it was from new anti-virus software, but apparently it is the overheating issue. I took the side panel off and have a small floor fan aimed on the computer, but it still shuts off. It is very annoying and I'm very unhappy with it.

After about a month of shutting down unexpectedly mine finally died altogether. (although the blue LED remained lit on the case)Had a PC technician look at it, apparently shuting down is a common problem with the Aspire L100 due to excessive heat. What he found was some damaged components on the motherboard relating to the 12V power supply. The 5V supply was fine which explained why the LED was lit and the bios beeped as it tried to boot. The 12V supply was non existant and therefore no fan or hard drive available. I was told it needed a new motherboard and will have to send it back to Acer for repair. The Aspire L100 motherboard is a proprietary one and cannot be replaced with a standard mini ATX form. Out of warranty so guess this is going to cost me!

The issue with these types of computers it quite simple. The machines fo no come with enough of room or openings to allow the components to ventilate. I would suggest taking it to a local computer repair shop so that they can modify the case to add in a ventilation fan on the sides of the case. Note they may need to drill out a hole for the necessary fan install. But it may allow you to use the pc without it overheating the system.

Im not a expert but my opinion would be to just buy a new power supply. Installation is easy. Thats one thing that gets replaced most often out of all pc parts. I would wait for a expert opinon though, good luck
