[Svetoslav Borisov]

###HP laptop models affected so far:
HP EliteBook 840G1/G2
HP EliteBook 850G1/G2
HP ProBook 650G1
HP EliteBook 8460p
HP EliteBook 8470p
HP 650 Notebook PC
HP ZBook 15 G1/G2

Battery capacity always reported as 100% by upower command in Ubuntu 16.04.5 LTS - 4.15.0-36-generic (tested with older kernels as well).
Upower info:
  Installed: 0.99.4-2ubuntu0.3
  Candidate: 0.99.4-2ubuntu0.3
  Version table:
 *** 0.99.4-2ubuntu0.3 500

the /sys entry has
POWER_SUPPLY_CHARGE_FULL_DESIGN=4557000
POWER_SUPPLY_CHARGE_FULL=4557000

so it seems either the kernel or the hardware is reporting the info, reassigning to the kernel

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".

Thanks in advance.

Hello Cristian,

This issue is happening since kernel 4.13.0-32-generic. I haven't tested with older kernels.
I expect to see a capacity less then 100%. I am testing this on an old laptop, with a battery which must be detected as less then 100% capacity (at least this is what is shown by HP Support Assistant utility on Windows - screenshot attached). I've also been informed that the models below have also been tested and they report 100% as well.
HP EliteBook 840G1/G2
HP EliteBook 850G1/G2
HP ProBook 650G1
HP EliteBook 8460p
HP EliteBook 8470p
HP 650 Notebook PC
HP ZBook 15 G1/G2

Could this be related to manufacturer limitations?

I have tested with the latest upstream kernel - 4.19.0-041900rc8-generic. as you suggested, but I still get the same result.

If you have any other ides, please let me know.

Thank you!
