Acer Aspire 2920 won't turn on, although plugged in with battery
I can't turn on my Acer Aspire 2920, eventhough the adaptor is plugged
in and the battery was previously charged. The LED on the adaptor is on. Just 1 hour ago my laptop is working, then I set it to hibernate, now it won't turn on.

Re: Acer Aspire 2920 won't turn on, although plugged in...
First of all, what I'm about to tell you are general troubleshooting techniques - I make no claim that they will fix what you describe, but they may help lead you to a solution.
Unplug the AC adapter and remove the battery
Plug in the AC adapter and attempt to power on the laptop
If it doesn't power on, see #6 below. If it does power on, but doesn't boot the OS, restart - pressing [SPACE] as the first Windows splash screen appears. When prompted, choose to delete the hibernation file and start a system boot.
Shut the system down, disconnect the AC adapter, reinsert the battery, and attempt to power the laptop. If it doesn't start we know, at the very least, there's a battery problem.
Plug in the AC adapter. If it shuts down immediately, or won't power back on after a shutdown. . .
. . .there's a problem with the system board, probably the ciruitry associated with charging the battery.

I have several starting problems with my Acer Aspire. To start with,my On Switch doesnt work so I removed the strip cover and use a matchstick (the non-red end) to push the round black dot in a small square at the extreme top right- hand corner above the keypad. Sometimes it's my adapter lead which works with other laptops so I figure it must be the laptop connection. I keep wiggling the adapter lead close to the laptop connection and push it in hard. My lead is the rotating kind so I try very hard not to move it once connected. Also because I"ve removed the start cover. I have to softly clean the connectors at the top lefthand side and the right. Hope one of these things help you and you don't have all three problems as I do.
Try removing the battery, it may be defective. Remove the battery and see if the unit powers up when plugged in. Check to see if the charge light at least comes on when it's plugged in....if it doesn't, then the socket the power supply plugs into may need to be re-soldered.
There could be a problem with the battery. A fast check to determine whether you have a problem with the power
adapter, power cord or the laptop's battery is to turn off the laptop,
remove the battery, connect the power adapter, turn on the laptop &
see if it works.
If the laptop works directly from the power adapter
with the battery removed, then the power adapter is good. In this case
we can suspect that the battery is defective & needs to be replaced.
If this did not work, try also disassembling the laptop & make sure
that all main components are seated properly. Also make sure that all
ribbon cables interconnecting the various components of the laptop are
Ckeck if your adaptor has power on the connector to laptop.
Might be damaged power cord (to and from the adaptor) or broken adaptor.
While there was power in the battery, it was running, but not charging.
Now the battery is emty and can't be charged because of broken adaptor/cables.
If you find there is no power from the adaptor, bepair it or buy a new one.
Do not try to repair the adaptor by yourself if you are not a technician, it is DANGEROUS ! Either give it to a qualified servicer, or betteer, buy a new one.
