NT 4 did not implement ACPI support, and your vendor elected not to develop their own for NT. Thank the vendor. Win98 and Win2K both have a common interface for ACPI.

Consider the context of NT - MS sacrificed features for stability; NT 4 is coming from even pre-APM, in the Win95 context, and I don't know how much experience you had with the early APM stuff, but it was not stable and reliable.

>>I've just noticed that it may also help if I declare lpStatus as REPLICATE(SPACE(1), 12). Running it this way under NT does returns some values....it's just the first 4 bytes all return 32 and the last two 538976288 !?!?
