do you see different numbers for this hardware when booted in windows? Len, I have seen a lot of batteries which show 'last full capacity' smaller or greater than 'design capacity', and (as I know) there are not ACPI related programs that may be confused because of this. Also, windows does not show 'last full capacity', at least I do not know how to get one.

In that case I suggest: percent=current_capacity>design_capacity ? 100 : (design_capacity/current_capacity)*100; ACPI does not calculate percents. This is a some userspace utility. Modern chargers have a threshold then they do not start, 97% might be easily inside this threshold. If you discharge your battery a little bit more, say to 85%, and connect charger, it should charge until 100% again. |
