Macbook air 11 inch Mid 2012 randomly shutdowns

[Fairuzzhh]

Hi, i have my mba battery first replacement after long time. Then i have some issues, the mba keep shutdowns randomly. the shutdown cause is -2, does anyone know how to deal with this? should i change my logicboard? is it from hardware or software?
This is the log before randomly shutdown happened,
Fyi my battery capacity rise up from 5109 to 5317 after calibrating.

could be a setting in system presences were the macbook is schedules to shut down
check the settings in "energy" to make sure the battery and power is set to your liking.
let us know if that helped.

Does it happen when the lid is closed and you're not using it? If so try disabling hibernate/deep sleep.
