Version-Release number of selected component (if applicable): kernel: kernel-2.4.21-4.0.1.EL apm: apmd-3.0.2-18 How reproducible: Tested on one system. Not sure if reproducible but seems to be simple: apm is not compiled into the upgraded kernel. Steps to Reproduce: 1.

"apm: BIOS not found." sounds more like your laptop doesn't have APM support....
checked online today and did a little search... while there are no concrete links, it seems that APM does not work on this laptop (how can anyone make a laptop without APM support?!?) and ACPI only if the bios is patched...
