I had to reload EVERYthing on my hard drive for an IBM ThinkPad A21m. After using the recovery disk to load Windows 98SE I then went to the IBM support site to reload all the updated applications and drivers for my system. After all that, here is what's happening with my computer:
Fn-F3 key combo--the monitor off function--does not work at all.
Fn-F12 key combo--hibernation--does not work at all.
Fn-F4 key combo--standby/suspend--instead shuts down the computer completely.
Note that auto and timer settings for monitor off and standby suspend work fine; that is, when I set my power scheme to turn the monitor off after say 5 minutes, then standby/suspend after say 7, these functions run just fine. Likewise, the setting for standby/suspend when the computer lid is closed--that works fine.
Hot/warm swap driver does not function: when the computer is in standby/suspend mode and I click the release catch on the UltraBay, the computer wakes up from standby/suspend; it's not supposed to do that while I'm switching UltraBay components.
Further, when I do a cold swap of components--from DVD-ROM to 2nd battery--and boot up the computer, all standby/suspend functions are gone from the menus in which they normally appear: the Windows Shutdown Menu, the Power Scheme Menus, etc. A cold swap from battery back to DVD, and the standby/suspend functions reappear.
