Hello, I own a lenovo ideapad gaming 3 15.6" laptop

So, yesterday I was upgrading my RAM into 16GB, everything was going fine until, trying to put this little metal that protects the 2 ram slow then accidently it moved to the left and sort of burned this capacitor PL202 . One of my friends tested the motherboard and the capacitor and told me it caused no damaged but still im confused on what exactly is the use of this PL202 capacitor and how i really be sure that nothing bad is going to happed to my motherboard as the time goes by. Would totally appreciated any comments about it. Thanks

pd: no, i didnt disconnected the battery or drained all energy before doing...

I have managed to solve this issue after following the below steps.

1. remove batteries(both internal and external
2. remove RAM and CMOS battery
3. leave laptop 5 minutes
4. plugged the RAM/CMOS/batteries and the LAPTOP was powered UP

Hello,
