fan cable, battry not detect, osx indicator stay at 0%, not charging,

what is that small cable next to right fan cable on the logic board? the fan power cable has four small cable. the cable i am asking has only 2 small cables.

i was cleaning my macbook pro's logic board from dust. i also put in a new and better thermal paste(arctic silver). during the process, i broke 1 of the leg of the cable next to the right fan(but not the fan power cable). i did broke the housing left arm. but the cable still seated right and secured. when i try to boot up my mac, it boot correctly but i just found out today that the battery wont charged. when i push the button on the battery it turn on about 4 dots(80%).

On the top right of the screen, if i click on the battery level it says 0% and stays on calculating charge time. i wonder is it because i broke the housing or what.

this is the actual pictures:

my question is it the source of the problem? thx

can i solve this problem by soldering the cable arm directly to the logic board? just the right side of the cable. the left side of the cable is fine.
