You need to try to isolate the problem. Try connecting an external monitor to your laptop. Press function screen keys. If you have a picture on your external monitor then you have a video problem - most likely an inverter, although you may need a new screen, unlikely but possible.

If you have no picture then you have a system problem. Disconnect the battery and AC adapter. Remove the memory and reseat. Repower your laptop and see what happens.

Does the laptop come on when you plug in the mains and take out the battery? If it doesn't then it could be a faulty power switch.

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.

Sai.

Might your switch be non-functioning? Can you check that independently?

Otherwise, sounds to me like you did eveything.

Same thing happened to me with my dog once. I let him out and that was it! :-)

Acer 7720 will turn on and work for about 5 mins and shut down


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.
