I have a Macbook Pro 13" Retina (Early 2015) running 10.12.6 with a broken battery (Replace now alert) but I still couldn't find a proper battery in my region.
In this case I should shut down the device to move and it seems loosing power also resets the date and time and also breaks hibernate mode which I can use.
I'd like to know is there any solution for forcing AC Mode so it ignores battery (Performance issue due to changing between battery and ac somehow in runtime).
I also tried SMC and NVRAM reset but no chance either.
Please let me know if there should be more explanation.
