I have an Acer Aspire 4520 that just will not turn on. It appeared to have gone into sleep mode but when I pressed the power button , the led's flashed briefly, then nothing. I tried wth just the battery, just the AC adapter, tried another AC adapter with the same results. Screen doesn't light up, no post beep, no bios, no fan, nothing. If I hold the power button down, everything flashes continuously, I reseated the RAM, HDD, Optical drive. I tried starting without the HDD, then without the optical. I disconnected everything that can be disconnected with the same result. Please help. It may also be worth mentioning that when the AC adapter is plugged in, the charging light is on until I press the power button. Then the LEDs flash, and then nothing.
