Need to adjust backlight brightness for LCD display on laptop

[brinstar117]

I have a Sony Vaio XG-29 and formatted the default OS install with all the bloatware attatched.

I did a fresh install of Win2k Professional and installed all relevant drivers. However, when I was playing around in the original OS install (Win98SE) I adjusted the brightness through software and lowered it.

To my dismay when I loaded up Win2K, the backlighting brightness stayed the same and I now have no way of adjusting it.

Short of reinstalling the default OS through recovery disks just to make the screen brighter (and permanently set once I reformat again) are there any options for me?

I tried searching for the program that allowed me to adjust backlight brightness in the recovery disks. I found it and installed it. However it doesn't work in Win2K.


Proprietary software sucks

I long for older laptop designs where the backlighting was adjustable by a small manual slider on the side of the screen. I think that would have been a lot easier than trying to reconfigure things through software.

I'd really appreciate any help or suggestions!

Not familiar with the Sony's but are there any controls on the kybd for ajusting the LCD brightness? Acer puts them on the arrow keys as do a few others. The compaq I have has them on the "F" keys. You usually have to use the "FN" key in combination with those keys to adjust the brightness. Toshiba has drivers for W2K that allow adjustments to LCD brightness through the software. They are two part drivers, one of which is a Toshiba specific ACPI driver and the other for the LCD. Double check Sony's site for them. If that laptop doesn't have W2K support, then you might want to look at other Sony models driver's. Also, on the Toshibas, the LCD brightness is under the power management in the control panel.
