Sometimes the backlight won't turn on in the laptop. I don't think it's a connection issue. Sometimes either the laptop's hardware or the video card is just not turning the backlight on. I can see that the display is on by the way... just so faint as to not be recognizable unless in the sun or a flash light is shined on the screen. 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. The laptop backlight then comes on and will work find if I disconnect the external monitor. The backlight only seems to go off sometime immediately after boot. That is WHILE the laptop is posting. It shows the American trends bios screen for about 1 second and then the backlight turns off. 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. This has frequently caused the backlight to stay on a half second longer but beyond that no result. Anyone have an idea about this thing? It's very frustrating because it makes the laptop less mobile. It means that at any time on the road it could be almost entirely unusable... since the only way to fix it is to plug an external monitor into it.
