charger squealing noise
I have a Acer Aspire 5520 laptop and since i updated to windows7 the charger has been making a high pitch squealing noise when plugged in.?
the squealing noise is coming from the power brick of the ac/dc cord. It also has been getting very hot and the noise has been giving me a constant headache. Anyone know what to do to stop this noise? I cant call acer bc their customer service sucks and wont let you talk to a human being unless you're computer is under warranty. PLEASE HELP ME!
