I'm running a Ubuntu based distro on a 2013 (edit: 2012) Macbook 13".
I bought a replacement battery from iFixit about 2 years ago. Battery's been working great but lately I've been having an issue. The battery time displayed the correct time remaining but the percentage was dramatically off. This was causing the unit to hibernate while the battery still had 1.5h of charge left (displayed as 2%).
I wanted to calibrate, but because I couldn't drain the battery as recommended, I edited ``UPower.conf`` to ``UsePercentageForPolicy=false`` which then let me drain the battery.
After draining the battery I left the machine alone for 5h and then charged overnight.
Unfortunately now the machine won't see the battery. Pressing the physical hardware power key I get 5 flashes. The machine will boot while plugged in via Magsafe.
I've tried:
* resetting SMC
* disconnecting the battery and leaving 24h
I still get the same result.
2 questions:
1) anything I can do to fix this with existing hardware?
2) will buying a new battery fix this?

EDIT: See screenshot of the Coconut app's main screen. Looks like the machine is completely ignoring the battery.
