From: Calab on 5 Jan 2008 22:08 I've got a new Gateway T-6815 laptop. This machine comes from Gateway with Vista pre-installed. The first thing I want to do is wipe Vista and install XP Pro SP2. I've got XP installed and mostly working... Still need to find audio drivers. My problem is the display. I've got the latest video drivers from Intel - 965 chipset - and they installed fine. Unfortunately, these drivers turn the backlight WAY down and I can't find any way to correct this. I know the backlight is working because the display is great when in the BIOS. Anyone have any ideas how to correct this?

Interesting. Could it be due to XP's bad battery management? Vista increased my battery life by about 45 minutes or so on my laptop. Maybe the power management is throttling back the LCD due to low battery? Does it still do it on AC mains?

Does it still do it on AC mains? Doesn't matter if it's on battery or AC. Tried adjusting power modes in the Intel settings and Windows power management with no luck. : (

Did you back up the original drivers and so on that came with the laptop, or do you have them on a CD or something? Perhaps there is some utility program that is intended to be installed to manage backlight settings or something? I don;t think the backlight is part of the display driver system. Could it be an issue with the display driver, though, like a gamma correction error or a brightness\contrast setting thats wrong?

Look into the bios settings. There are likely to be two levels settable, one for battery power, and one for AC power. Also consider installing Linux. I suggest Ubuntu. You can get the whole schmeer free as a CD from shipit.ubuntu.com. -- Chuck F (cbfalconer at maineline dot net) <http://cbfalconer.home.att.net> Try the download section. -- Posted via a free Usenet account from http://www.teranews.com |
