Question about Acer (ACERMOTHERBOARD)
I can' t lighten by laptop screen. Only able to use it through an external monitor.
Doesn't seem to be a toggle F5 issue
It may be that your backlight has burnt out, or your LCD inverter has gone bad, if you can hear a high pitched sound coming from the screen it is more than likely the converter, you can order replacements online...
