IBM announced new software for w2k on Software and Device Drivers page:
Power Management Features Windows 95, 98, Me, NT, 2000, XP;
Configuration Utility;
But files on Configuration Utility page are unable for downloading...
Works for me. Do you get a "Terms and conditions" window? You have to choose "I agree", otherwise it won't let you download. What browser are you using? Do you have enough free space in you email account? So I can send you the file.
