Acer Aspire 4720Z laptop Won't power on

February 21, 2010 at 09:37:56
Specs: Windows Vista
My Acer Aspire 4720Z laptop was on and operating normally, then suddenly just turned off. It didn't go through the normal shut down process, seemed like the battery died out but the battery indicator showed a full battery. Now it won't charge or power up. When I push the power butter, the battery LED flashes 8 times and nothing else happens. AC adaptor shows that it is receiving power from the outlet but the computer is not taking the charge and the LED isn't lighting up when the power cord is attached indicating that it is charging. (The cord's output is 19V 3.42A). I removed the cord and the battery and held down the power button for 25 seconds, then plugged in the cord and tried to power it on with absolutely no response, then replaced the battery without the cord and got the 8 flashes again. What could be the issue?
