A recently acquired Acer Aspire 6920 LF1 is giving me a headache!
I can get it to go into BIOS occasionally, but only when it is running on battery power.
The AC power pack seems to charge the battery ok, as the charging light and blue LED's come on.
When I turn it on with the power pack plugged in, the blue power LED's and the Bluetooth LED's light up briefly, then go out. It then cyclic reboots and the CineDash panel will light up but the screen stays blank.
Sometimes I can get it to go into BIOS when it is running on battery only.
The CPU fan spins ok and power is getting to the DVD drive also.
I've checked the power jack and it seems ok, swapped the RAM out with known working sticks, tried different power supplies of the same voltage/polarity, tried running it on AC only, removed, cleaned and replaced the power connector to the motherboard.
Any ideas?
