I doubt that IBM would have stopped ACPI support. You should be aware
that APM and ACPI are mutually exclusive.

Are you using any PCMCIA cards? Did you try the boot parameter
"acpi_sleep=s3_bios" ?

 Thanks in advance, and sorry for my bad english. j1v

tpctl works only with APM. It doesn't work with ACPI. If you want to
use APM, you need to put in the acpi=off parameter. If you want to use
ACPI, please read
