My Acer Aspire 4520-5582 PC Notebook dosn't turn on. All that appears is a blank screen what do i do?


it could be a few different issues. 1st off, i advise that you try to turn it on while it's plugged into the wall and the battery is in. if it turns on, then shut it down again and leave it alone for a few hours to let the battery fully charge. if it doesn't work, then take out the battery and turn it on while it's plugged into the wall. if it turns on, you've probably got a bad battery. if not, then it's an internal issue. most likely a power supply.

if it's your power supply, google your particular computer model and how to take it apart. carefully do so, and when you remove the power supply, order a new one. i'd advise doing the same if it ends up being simply your battery. just go to the acer website and order a new battery to fit your particular model.

good luck!

Acer Aspire 1640 power problem


Will the unit work without the battery? The new Lithium Ion batteries can be overcharged and then cause all kinds of strange problems. Take the battery to a reputable electronics shop or Batteries Plus and have them run a voltage and current test. The current test being the most revealing. If either of these is higher than the level printed on the battery, dispose of it. Also, check ACER's web site for battery problems. All the computer manufacturers have had battery problems.

Good Luck
