The backlight needs a higher voltage from what I understand, so there's a small circuit board, usually located right under the display panel itself, that raises the voltage from what the battery is putting out. since the only way to fix it is to plug an external monitor into it.įrom my experience with most laptop hardware, the backlight is usually governed by the little inverter board that powers it. It means that at any time on the road it could be almost entirely unusable. This has frequently caused the backlight to stay on a half second longer but beyond that no result.Īnyone have an idea about this thing? It's very frustrating because it makes the laptop less mobile.
I've called Asus about this a few times and they always start by talking about an "electrical reset" which apparently accomplished on this unit by leaving the battery out for 10 minutes and then booting the machine with ONLY the battery connected. It shows the American trends bios screen for about 1 second and then the backlight turns off. The backlight only seems to go off sometime immediately after boot. The laptop backlight then comes on and will work find if I disconnect the external monitor. I've come to this conclusion because the only way to fix the issue when it happens is to plug an external monitor into the laptop, set it as the primary display, and then reboot. just so faint as to not be recognizable unless in the sun or a flash light is shined on the screen. I can see that the display is on by the way. Sometimes either the laptop's hardware or the video card is just not turning the backlight on.
Sometimes the backlight won't turn on in the laptop.
