1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The motherboard could be defective & needs to be replaced

OOPS.... OK.... it may be serious but it may also be easily solved. If what i tell you now doesnt work then the laptop is KAPUT.
Remove the battery... then remove the hard drive and the memory chips. You should find all these under latches at the bottom of the laptop .... the hard drive sometimes pulls out from the side somewhere.

ALSO TRY ANOTHER POWER SUPPLY because youyrs may be faulty. TRY ANOTHER POWER SUPPLY FIRST OF ALL !!

Once you've done that you must put it all FIRMLY BACK... If that DOESNT work you may have a DEAD computer.

I have installed windows XP on Acer Aspire 4520 and since it was not booting up normally i installed all the drivers in Safe Mode. Even after doing the same it's not starting normally just a blank (Black)...


your computer your laptop will just shut itself down and get a black screen unexpectedly, which is due to: power overload in the AC adapter, overheated processor / clogged fan, overheated battery, pushing the power button, Windows telling it to, the BIOS telling it to, loose wires (especially the power cord), or intermittent short circuits. The most common problem is cooling. the battery should be removed from the laptop and allowed to cool to room temperature before attempting to use again.
