The problem is due to overheating of the CPU. you need to open the system and clean it with an air blower mainly near the processor areas with an air blower, this will most probably solve your problem.

But if the problem still persists, check whether the CPU cooling fan is working properly or not.

That's it.

My Acer aspire 4520 windows vista laptop is locked. can someone helph me? to change my user name and password. I forgot my password.


Hi there, this may work, try this.

Take off laptop battery, remove power cord, turn laptop upside down.
Just take off screws on the covers you see, which let you see HDD, Memory,Wireless card,.... ,
take off the cover or check on line for service manual for your specific model on how to remove the plastic cover/ covers, which is covering the CMOS battery which is some time wrapped up with yellow tape. Just remove the battery by holding on the white connector which attached to the motherboard with black and red wires. Gently pull from the motherboard.

Now without the CMOS battery, connect power cord and turn on the laptop, it should turn on. Now turn off , remove the power cord, check voltage on battery , it should measure very close to 3volt (2.5 to 3.0 volt), otherwise get a new one, connect the battery, put back covers, and now you set a new password.

Acer 4520 Dead, Blank screen , No response...


It sounds like something on the motherboard has possibly shorted out. That can range from the CPU to RAM to the DVD. If it's still under warranty I would suggest sending it in for repair.

If you do send it in, please let them know to backup your harddrive if they have to reformat and restore it for any reason. Your important files are still there and safe.

Acer 4520 Power up for 1 second and turns off


Can you hear the system fan running? If the fan fails, the PC shuts down itself to protect the processor from FRYING.
