MISSING IN ACTION/KNOWLEDGE BAR

I RECENTLY HAD TO FIX MY COMPUTER, (BATTERY HAD TO BE REPLACED) BEEN MISSING IN ACTION BECAUSE OF IT, BUT I'M STILL HERE PEOPLE! ITS BEEN FRUSTRATING TO SAY THE LEAST, WHEN A TECH GUY TELLS YOU THERES ANOTHER ISSUE, & IT WILL TAKE ANOTHER FEW DAYS, BUT I'M GLAD THEY FIGURED OUT THE PROB RATHER THEN NOT FULLY DOING A FULL DIAGNOSTIC...

S/O TO MICROCENTER IN BROOKLYN.
