you can use the unit without the battery. Remove the battery, plug in the charger/power supply and turn on the unit and wait for the result. if the problem persist?..... maybe the fault is in CPU fan. check the fan...overheating the processor. Cleaning the heat sync and reapplying silicon compound on CPU's can cure the problem.
Go to Power Options --> On the plan you are using select change plan settings --> Change advanced power settings --> Scroll down till you reach battery and click the + next to it to expand the settings --> Where it says Critical battery level and Critical battery action (on battery) make sure that the level is at 5% and the action is to hibernate. If it's set to do nothing, it will keep running until it's out of battery and completely shut off. Plugging the AC adapter would give it more power. If that isn't the problem, check your battery's connection and consider replacing the battery.
Check the ram memory and se if they are plugged well and working ..leave it work with one at the time if you have more than one module of ram ..and see if this is the issue .. from what you say it is doing ..sounds to me like a cpu fault .and more likely a fan failure...cause it wants to start but it shuts down as a protection in the moment it detects the fan not working ..So open it up and check the fan ..or replace it ...If this will not solve ..replace the cpu
Gaming (and graphics application) consumes more CPU/ Processor
resources and due to the heavy processing the PC (CPU & GPU) heatup. Excessive
heatup beyond usual is alarming and PC shuts down by itself when the processor/ GPU temperature exceeds the safe temperature limit. There are mainly two reasons for heatup. Laptop heating issue generally occurs due to fan
failure, which may damage the system, if not checked properly. Another
most likely cause of overheating is the dust present inside the laptop, which clogs
the fan and heatsink. 1. Make sure the fan is running. (if not it needs replacement) 2. Clean the fan and heat sink (thermal module). Click here for GENERAL Acer Laptop disassembly instructions and refer to Removing the System Fan/Thermal Module
after removing the outer cover. Take out the fan and heat sink. clean
them with the help of tooth brush and put it back. Also, repair manual
can be searched online or downloaded for referrence. The
procedure is very simple, but if you are not comfortable with working
inside electronics, I suggest that you should get you laptop checked
by a professional for servicing (if required). I believe immediate
action is required to prevent any damage to your machine and data.
Hope it Helps! Let me know if i could be of any further assistance. CreativeTECH
First thing I'd check is for a BIOS update for your computer under the Acer support pages (acer.com). In some cases, thermal control updates are included in newer version of the BIOS, if it is a manufacturing problem.
Goto http://www.cpuid.com/hwmonitor.php and download Hardware Monitor, start the computer and immediately run the hardware monitor app to check how high the temperature on the CPU gets before it shuts down.
Continuing use under this condition may damage your Windows installation because of the sudden shutdown.
Well, I'm not exactly sure if it is the cooling fan (you would have to see if its working), but it definitely could be an overheating problem. Another problem could actually be the battery, even if you have it plugged in, the battery can still cause it to shut down. If your computer is able, I would try using it without the battery and see what happens. And I believe that the cooling fan will fit. Here is a good site to help you troubleshoot your problem
if for any reason the computer shuts off immediately it could be from the CPU fan, your computer probably has problem in its coling system, it could be the fan has so many dust obstruction, to solve this you need an expert to open up your laptop and clean the fan. in theory if the cpu reaches its peak temp. it will automatically shuts down to prevent damaged to your system. hope this helps you...
Turn over notebook and remove bottom covers. clean out heatsinks near the fan.
The fan usually looks very clean, but look inside the fan housing and you'll probably find a blanket of lint/dust completely blocking the air passageways (even if they look clean from the outside).
If you remove the heatsink off the chips make sure you put on new thermal paste.
Some models it is very easy to get to the fans, others you have to fully disassemble the notebook
You could also try cleaning it out from the outside with an aircompressor, just leave it off for a day in case the is any moisture in the aircompressor lines. This may fix it but if its really clogged, you will need to open the unit and manually clean it.
