hello:
i have a amilo pro v3505 vl2 laptop which exhibits what seems to be a common problem (?) the problem is particularly bad when on battery power, the laptop screen goes black. the actual image on the screen is just visible if viewed with side lighting. the laptop is fully functional. an external monitor is unaffected. i have had the inverter replaced in the laptop to no effect - the going black problem persists. it occurs less frequently (but it still happens) when the laptop is on mains power.
it appears that the issue may be due to (windows) drivers? is a definitive fix known? i would like to get this problem sorted. i would appreciate any help with this.
