Laptop in question is TP390e with Win98SE on clean installation (done about a year ago) without the proprietary IBM utilities. I want to brighten the screen. Have it set in BIOS for maximum brightness -- which makes no discernable diference -- but have seen no setting in Windows for adjusting brightness. There is a manual slider on the bezel which seems loose and does nothing. The screen is passable but dim compared to other laptops especially in bright light. It will go brighter; for instance on a restart it will step up to a nice bright level just before shutting down Windows. Any suggestions? By the way, will be upgrading to W2KPro soon -- any chance that will provide a solution? Thanks!

What's the warranty on your machine?

Most LCDs on laptops will dim over time.... replacing the LCD is your best option (especially when the control/slider comes loose and does nothing to improve brightness).

You could contact your nearest IBM authorized repair center and have them order the part and you'll bring in the laptop when it arrives. If that is not the problem, or they can fix the slider, they can return the LCD as new & unnused.

The fact that it starts out bright and then dims out may mean that a capacitor is going and they may be able to replace that and fix the problem (I've had this happen with a Winbook laptop -- $16 total repair).

Anna777 -- yeah thanks, I have considered a repair and that may be what I must do in the end. But the fact that after selecting "restart", just before the splash screen disappears, the display jumps up to a nice level of brightness, which it holds for a couple of seconds just before the shutdown, makes me think that there is a software answer. Obviously, the screen is physically capable of a brighter display -- I just have to find out how to tell it to do so. Thanks -- any other ideas out there? I have tried TweakUI but none of its settings seem to address this.
