My Acer L100 keeps powering down at seemingly random intervals. No error messages appear, the hard drive slows down and the monitor fades to black in a matter of 2 seconds. Fans are clean and exhaust airway for the unit is fine. Is this a hardware problem or a software issue? Solutions? Thanks!
Wow...i am surprised no one has discoverd this and i am an amatuer. the power management software seems to be the culprit. i have posted the solution i used on some of the other overheating acer L100 questions. even if the fans run at top speed, the bios can read the wrong temps and also control the processer voltages too high which no fan is gonna cool......lol......check em out, my finger is tired.....lol.

ok guys this is the problem i work for Acer and basically if
you own an aspire L100 then you have to be prepared to modify your little bad
boy because of acers poor design and a crappy little fan the anything inside
the case feels like its on holiday in the tropics what you have to do is side
mount 2 extra fans with separate 12v supplies and your system will never
overheat or die on you if you have any questions on how to do this just email
me :-) me
I just opened an Acer Aspire L100 given to me - for the same reasons & the capacitors on the motherboard are swollen. This is a result of overheating. Once the capacitors swell - they fail to function properly a/k/a sporatic shutdown.
Had same problem, reformatted hard disk, installed vista 64 bit ultimate about 2 months aga and have not had this problem re-occur to date. I leave unit on 24 hours a day. This may work for others don't know but it worked for me.
I had the exact same problem. Behaved like it was overheating but wasn't hot at all. Called Acer and had a return authorization # in 10 mintues. Shipped it to TX for $35 and got it back 3 weeks later. They replaced the MB and it seems to work fine now.
Well, there is a small issue witht his as well, I also have one and the keyboard and mouse are wireless via USB, the machine cannot be worked with at all in safe mode due tot he fact that there are no USB drivers and you have no operation of either the keyboard and mouse. I have found that when the issue occurs, it even happens on line, I was looking at an online album on facebook quickly flipping through pictures and the fans start running almost nonstop untill the system shuts down. I can tell you that as an experienced hardware and software technician from Gateway, Dell, and Microsoft vista, that it seems to be a definate overheating issue. The case and the powersupply are insufficient to properly run and maintain a consistant temperature, thus causing an overheating issue to the point of shutdown. The OS has been reloaded with no change.

Re: Unwanted System Shut Down
The only way to find out if the it's software or hardware is to switch it on and keep pressing either f5 or f8 until you get safe mode menu click on safe mode and run it for a while if it goes off you know it's definately hardware most likely processor overheating or something loose inside if it carries on running without any problems you know it's definately a software problem a reinstall of your operating system should solve the problem

Step 1: Laptop computers can be wonderful devices, except when the need to troubleshoot arises. Acer laptops are no different. A quick way to fix many problems with an Acer laptop running Windows is to reset it to factory settings. Resetting your Acer laptop to factory settings can eliminate slow operation, registry problems, virus problems and spyware issues. What's more, a factory reset of your laptop may reduce the need for a full reinstallation of Windows.
Back up all necessary data to an external device such as a disk, flash drive or hard drive Make sure all programs are closed and shut down your Acer laptop. Detach any external hardware such as an external hard drive or printer. Press the Power button to boot your Acer laptop. Press "Alt-F10" on your keyboard when the Acer screen appears at the start of the boot-up process. Wait a moment while Windows loads the reset files. Select "Restore System from factory default" in the Acer eRecovery Management window. Click "Next" on the next screen to continue. Click "Next" on the following destination information window. This will pop up a notice telling you that resetting your Acer laptop will erase all data and restore the laptop to its original settings and configuration. Click "OK" in the notice window to proceed with resetting your Acer laptop. Wait while your Acer laptop is reset to factory settings.
#1 Make sure your laptop is free from virus, spyware and trojan. A virus or spyware can make your laptop run slow or even damage the whole system. Run a security scan to find out if there are infection files hidden in the system. The slow laptop would be fixed by eliminating the virus.
#2 Remove obsolete programs to release more hard drive space. Laptop slow problem sometimes would be caused by the less hard drive space. To optimize your slow laptop, you can try to delete those unneeded programs, files from the hard disk especially the system disk.
#3 Empty the Recycle Bin to retrieve more system resource. Your laptop slow symptom maybe arises due to the deleted files in the Recycle Bin. If you forget to empty the Recycle Bin, those files in fact still exist on the hard drive and keep eating up your laptop system resource so that the laptop will run slow.
#4 Scan and fix Windows registry. Do you know how important registry is in Windows system? Corrupted, invalid or malicious registry will slow down your laptop and make it run unstable. You would receive many error messages such as dll errors, Internet Explorer errors or blue screen of death in the using of laptop. Thus, it is necessary for you to fix your slow laptop by cleaning registry errors.
Try deleting all unwanted files like Temp files, disk clean up, disk defragmentation.
There are 4 c5707/5706 in the inverter transformer driving circuits, the cause of the problem was due to poor solder connection in the bias circuits of the transistors. Make sure to check that after you install the new transistors otherwise you will blowthem up. Common problem with this model. When the circuit drwas too much power from the power supply, it will shut itself off to ptotect itself.
If the hard drive is OK then you can remove the hard drive from the desktop case, and insert the hard drive into a USB 3 1/2" hard drive adapter case, this should come with a power adapter. These are available at your friendly computer shop.
Boot up the laptop then plug this USB hard drive adapter into the laptop's USB port. The laptop will see this as an external USB hard drive. You can open the various folders and files on this external drive and copy the folders and files to the laptop.
You can delete the Windows folder and Program Folders on this external drive to free up disk space and use this as a back up drive etc.
If you are not sure how to remove the hard drive and install it into an USB hard disk case, then I suggest you get a computer savy friend to help you.
I have the same pc my power supply went bad after 2 weeks.Pack up the pc and return it ASAP I have nothing but problems with mine.Gateway use to make good pcs, those days are gone,mine was a gift and I had to keep it.
The CPU fan should turn on when the PC is powered on, and then it usually slows down until the workload on the processor causes it to heat up, then the fan spins faster, it might also be a power supply issue, but if your able to boot and its giving you messages and not shutting down then you should re-install the operating system.
All computers will shut them selves off or crash when fans are failing, or have failed. Cooling fans are plugged into the motherboard, and firmware on the MB keeps track of the system fans, along with everything else. If a system fan is failing, or has failed, the signal is sent to shut down. Some PC's will shut down cleanly, others give error messages, and some just freeze up. Of course, Bad RAM, video cards, and hard drives with bad sectors, can also cause problems like you have discribed.
I would write down any error messages, and beep codes, and then look them up online for a place to start.
This is generally caused by bad blocks in the Master Boot Record(Table). The drive itself is probably not salvagable. You'll need a reputable reapir person to slave your drive to another system to get the data off.
