 Three power management keys on 107 keys Win98 keyboard are not working properly.

There are several scenarios that may cause these buttons do not work. Below are most common found.

1. The keyboard is used with the old PC (Pentium and below (486, 386, etc.), most of them do not support Power Management feature in BIOS which is required.

2. The keyboard is used with new PC (Celeron, Pentium III, etc.), but the Power Management feature is disabled in BIOS setting.

3. The Operating system is Windows 95 or below.

If your desktop is not following any of the above, please check at Control Panel--System--Device Manager and under System Device. You should see the power management devices (ex. ACPI system button, Power Management Controller, and Advanced Configuration and Power Interface (ACPI) BIOS), otherwise these buttons do not work. The safest way you can try to make these devices installed is reinstalling Windows with command "setup /pj"

Note: Some mainboards with Windows98, these buttons do not work like they are intended to. For example, the computer may go to sleep mode by hitting Sleep or Power button. For the new PC with new Operating system (Windows Me and above), these buttons (power, sleep, and wake) will work perfectly.
