RE: z50 battery oddity
Interesting thought! But the z50 batteries are definitely li-ion, unfortunately.
I also have the AA battery-holder for the z50, but with NiMH cells, you get a
nominal 8 x 1.2V = 9.6 V, and this clearly sets off the "critical" battery
warning in NetBSD. Since then, I've been trying to hack the hpcbatterytable.h
file to find more ideal values to "calibrate" things, but I find that the
"vertical bars of death" that occur when suspending-resuming with the
experimental LCD blanking support in the kernel might be what's causing another
curious problem of window focus getting all screwed up in X.
Clearly, there are still things to work out on this platform :)
