Signed-off-by: Alex Henrie alexhenrie24@gmail.com --- MSDN says that "Charging" and "Discharging" are set based on all batteries in the computer, but then it makes it sound like the remaining fields are set based on a single battery. Since I do not have a computer with multiple batteries to test, I am proposing that we implement this function according to MSDN's description and change it later if that turns out to be incorrect. --- dlls/ntdll/nt.c | 73 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+)

Hi,
While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?
