way to reset 'Battery Wear' in ACPI ?
Let's say you have an ACPI compliant BIOS on a Toshiba laptop
but unfortunately the BIOS pages don't have an adjustments for recalibrating the battery, and Toshiba has not provided an updated BIOS for this laptop motherboard.
Your old battery shows 8% wear and zero cycles,
but really the battery is old and only lasts about half as long as it used to when new.
Anyone know of a WindowsXP compatible program
that can over-write a new value to the 'battery wear'
in whatever file it is stored ACPI ?
Is this battery wear value somehow written to a little prom memory file on the battery itself?
If not a Windows program
do any of the Linux distro's have ACPI programs
that could write a new 'battery wear' value.
I wouldn't have any problem with downloading a Linux Live CD
and running it from the CD drive if it would let me do this.
I have the free BattStat program installed

that reads the battery wear and cycles for me
but this program does not let me over-write what is already stored somehow.

I never found anything for that when I looked before, the battery on my toshiba now lasts all of 3 minutes. I finally gave in and ordered a new one from Amazon last night.
