Well Ted_E, you need the APM support installed under OS/2 as well as the Thinkpad system driver (APM.SYS + AODBSMD.SYS).
To get FULL suspend to work (memory dump to disk), you also need to create a dump file (as placeholder) with the corresponding DOS utility on a FAT partition (not really practicable if you got 2GB memory, such as I do).
W/o that, you still get suspend to work, just w/o memory dump. meaning your RAM does not get switched off during "suspend" and thus still uses up (some) battery juice.
I was wondering how suspend worked so well on my T42p without my doing anything. I take it windoze just maintains it in RAM as well since there is only the NTFS partition and a FAt32 IBM_Service partition on the drive, so if the battery drains complately its lost.
So OS/2 can be setup to save the RAM image to disk and restore from it? Are there instructions on how to do this somewhere? Or is this just for older TPs?
