Dead Acer Aspire E1-571
Hi Everyone.
My old Acer Aspire E1-571 has died. There is no response whatsoever. When I plug in the ac adapter, nothing happens, no blinking LEDs, just plain dead. The power button wont switch it on. I test the ac adapter and its working fine. With your help I think i can fix my notebook.
