[Bug 1588944] Re: Incorrect low-battery detected forcing suspend
Sorry Joe, this may be related to userspace as well, as I was able to
reproduce this with other kernels as well. Although not as reliably.
** Also affects: indicator-power (Ubuntu)

Title:
Incorrect low-battery detected forcing suspend
Status in indicator-power package in Ubuntu:
New
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu is detecting that my battery has depleted to low or 0% which
results in the OS forcing suspend. Normally this would be correct
behavior, but in my case the battery has closer to 90% of remaining
battery left.
I have experienced this with 4.4.0-22 and 4.4.0-23, and am currently
running 4.4.0-21 to see if it reproduces there as well.
I do have -proposed enabled so it's a bit hard to determine if this is
the kernel or something higher up the stack.
This does seem to be mildly reproducible. 4.4.0-23 being the most
problematic kernel so far.
Of course this is a relatively new laptop so this could be a hardware
issue as well.
