Hello folks, alright here is the situation.
I have an Acer extensa 4420 laptop, it worked fine for a few months, suddenly several times a day the backlight will go off.
I can press FN + F6(Backlight function) it would suddenly flash on then go off again.
Here is the mistery, when on battery power it NEVER happens.
ONLY when on AC power (few times a day).
Before going and purchasing an inverter board I would like some confirmation if this is the correct symptom of a bad inverter board.
Let me know asap AToters! Thanks.
