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 power button could be bad.
5. The motherboard could be defective & needs to be replaced

Acer 4520 Dead, Blank screen , No response...


It sounds like something on the motherboard has possibly shorted out. That can range from the CPU to RAM to the DVD. If it's still under warranty I would suggest sending it in for repair.

If you do send it in, please let them know to backup your harddrive if they have to reformat and restore it for any reason. Your important files are still there and safe.
