dm1 - Brightness level set to max after reboot on XP, Desperately seeking help...

I tried to install XP SP2 on dm1 (su4100 version), already up and running now.

The problem was about screen brightness, it seem that xp cannot remember the last brightness level. Every time I rebooted, the screen brightness always set to max level.

I have tried to change Intel chipset and vga driver, but still nothing.
all the Fn + key button worked, even for brightness setting.

Tried installing latest QuickPlay driver, it get worst (it doesnot match with function, in dv6700 Fn+F7,F8 for setting brightness, in dm1 Fn+F3,F4)

The other issue was "pop" noise when windows is starting, but I already solved with some registry trick (which was posted in this forum)

I owned notebook with XP before, and the screen brightness always followed power scheme, if I change the scheme the brightness level will set to the last it was.

So, anyone have any suggestion regarding my brightness issue ?

If some how I can't solved this issue, Is there any 3rd party software for managing power scheme like in vista for XP ?

Thank you, appreciate all the help....

 

Anyone ?

I had the same problem with my former macbook and XP. It sounds to me like it's just an XP quirk more than anything, you'll just have to live with it like I did.

Thank You for your response, I tried update the BIOS and XP service pack 3, but still no joy. I guess, I'll try to look the other way then.

Thank You
