I experience this behaviour since I got my laptop (No-Name IPC Starnote98)
almost 3 years ago, Dec 1998. Since I got APM working in a (mostly)
satisfactory way, I never wondered about it...
By the way, I went through all kernel revisions from 2.2.0 to 2.2.19, also
2.4.5 to 2.4.9. Currently running 2.4.9 with Debian 2.2.r3, numerous packages
from unstable. The kernel APM support changed vastly over that time period,
as I had to recognize by often experimenting with the kernel config again.
However, one thing never changed: spin up - spin down - spin up .. after
Suspend-To-Ram.
In the BIOS there is an automatic spindown after 4 minutes configured, but
actually almost never occurs due to buffer flushes. Anyway - the battery is
broken, so .. =)
Best wishes,
Frank
