You need working power for the duration of the BIOS upgrade. Personally, I
might take a chance with just line A/C, considering the length of time it
takes to do an upgrade, but you can never be certain. Other possibilities
are obtaining a UPS (which is another form of battery).

Certainly it would be nice to have an up to date BIOS before spending more
time figuring out suspend/shutdown problems. My 770 works without these
problems, and I can use the cover suspend feature. I don't do a lot of
suspend/resume, although I did incorporate it into the latest ibmtr_cs.c
Token Ring driver (I can't recall if it got incorporated yet into the
official stream).
