In most cases I have found that this problem stems from a bad charger not delivering the proper amount of voltage. Therefore the battery doesn't ever really get a full charge even though the power indicator may say it does. I would get a multi-meter and check the voltage at the charger tip and see if the power is fluctuating. Be careful regardless, a bad power unit may spike and terminate your motherboard.

My acer freezes for about 2 min at a time every 10 - 20 min. ive tried different opperating systems but it didnt fix the problem.


Sounds like you may have to open it up and cean out the cooling fins. That is a classic example of the CPU overheating and shutting itself down until it gets back to operating temp.

Acer Aspire 7720 shut down, no power light, battery and supply check good. Tried the power reset still no power light with AC supply. unit completely dead. Do I stick a fork in this one?


The laptop's AC power jack is probably damaged. All you have to do is put the fork aside :D, unsolder the old power jack and solder the new one in. If you are not good at soldering you can get it done by a qualified professional. Its a 5 minute Job and a pretty inexpensive repair.

Regards,
Sai.

I bought today my acer and it shuts down after a while and restarts automatically right after


Laptops/notebooks are configured to go into sleep or hibernate modes after so many minutes of inactivity. The amount of time varies whether laptop is plugged in to AC power or running from battery. You can change the amount of time and how the power button behaves by changing your power managment settings in the control panel.

Aspire 7720-6569 laptop automatically shutoff and won't turn on.


hi,
Please try following DIY
1.Please remove the battery and then press the power button for a minute without connecting the adaptor then refix the battery and check whether it is working.
2.Check after removing the battery with adaptor only.
3.If then also it is not working check whether the num lock is responding if yes then this is a RAM refixing or changing issue otherwise a motherboard issue if the adaptor is working fine.
