I have an ACER ASPIRE 5315 SERIES. About a week ago I went to plug my laptop in and the part that plugs into the laptop made a zapping shocking kind of sound. the laptop was running but then within 15minutes the laptop shutoff. since then it hasn't even turn on or hasn't even seem to be charging since the light for charging doesn't come on...I bought a new charger and plug it in and still nothing comes on at all...took the laptop apart, taking the battery out, holding the power button down for 20 secs. took the hard drive part out but it all back together and try to start and still nothing. took it apart again and didn't notice this before but when I plug in the charger to the laptop it starts to make a faint but noticeable clicking noise but once unplug it goes away.....what could be wrong with my laptop?
