Problems with sierra running on mac with no battery.

Ok so, I asked a question yesterday about updating, I managed to find a fix and run my mac at full speed using OS 10.7.5, however, after the update my "fix" stopped working, maybe due to .kext updates.

Now it just randomly restarts and is super slow....

I am still trying to get arround this, I will probably buy a new battery next month, but until then, I have to work.....

It makes the chime sound and loads everything normally, but when I start typing my password BAM, restarts on it's own.... I already tried smc reset again and nothing...

Same hapens on recovery mode, loads just fine but after a few seconds restarts.

I am going crazy here.
