Huh, so *that's* what's going on. I normally just pay attention to the
percentage left, since the minutes display was horked. The patch against
2.4.8-ac6 below fixes the same problem for my PCG-XG29. (It may fix it
for a few others as well, at least the XG29K, perhaps the XG19/19k as
well. IIRC, they just differ in the screen size and which version of
windows you have to blow away.)

It's looking more and more likely that they're all backwards. Hey, at
least they're consistent, right?

My old Sony PCG-505G does seem to get it right.

Hmm. You may be taken care of by one of the exceptions already in
dmi_scan.c, and it'd be interesting (and useful) to find out. If you've
got a few minutes, could you open up arch/i386/kernel/dmi_scan.c and
either uncomment or add the line:
   #define dmi_printk(x) printk x
after the existing "#define dmi_printk(x)".

With that, upon boot the new kernel will show the BIOS version and date,
which dmesg will show. If they are one of: 

  R0203Z3  08/25/00
  R0203D0  05/12/00
  R0121Z1  05/11/00
  R0208P1  11/09/00

...then in fact your BIOS also gets it wrong, which would be
aesthetically pleasing in a sort of perverted way.

Yes, I think the same is true with my PXG-XG9 (minutes being wrong),
but I haven't actually tested if the patch works.  I always assumed
it was because I have two batteries installed.

Cheers, Andreas

If the patch doesn't work for yours, then all you have to do is to open
up arch/i386/kernel/dmi_scan.c, and uncomment a #define as my previous
email to the list. Upon boot up, you should see the BIOS version and
date, and if it's not in the list then we can add it in easily.
