components knocked off the motherboard. maybe even the CPU/GPU ball mounted chips will get knocked off in some falls. Re-flowing it might help but use cation. a good look over for parts that look lifted first would be a start.

budelrum  the battery is flat (discharged) at 3.8 volts you need to charge it to 4.2 and try again.

why is this still up. you can’t replace this part so the title is misleading. This part is torn easy you must remove the board from the tablet with the touch cable connector unlatched but the cable still in. if you try to bull it out first it rips.
