SOURCE: acer laptop wont turn on has power button light up
This is a common problem with Acer units, both desktop and laptop. The motherboard fails to read the system BIOS at startup. Removing the battery from a laptop merely removes the power source, but not the stored memory. If you are able to locate the CMOS battery, or the cell battery the size of a US quarter dollar, that is the system battery. Remove that, wipe with a lint free cloth (coffee filter) then replace.
If that effort fails upon replacing the cleaned CMOS battery and laptop eneregy source, then a new coin cell may be the solution.
If a new coin cell fails to resolve the problem, the motherboard itself is the culprit. Time for a new laptop or desktop.
Hope this helps you...

Hi,
You can fix it by doing this. but first you need to make sure you leave your house for at least 4 hours so you don't have to be hearing that frigging noise, IT CAN BE DONE! i fixed it.
my unit would start beeping as soon as I plug it in wall, and red light come on, the software is telling me the battery is unplugged
this is what i did in order.
1. unplug all cords, connected to the unit, and power cord to the wall.
2. hold the power button
3. still holding the power button, Connect it to wall. (red light would be on but no beep)
4. I watched TV for 6 hours, red light still flashing
5. disconnect from wall
6 connect back to wall
I heard the unit click one time and green light came on, is charging now....
