Lenovo ideapad motherboard's capacitor

 MaejorTripper -
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 this and yes i know i shoul've have. but now were here and im a little worried about this "not-burned but looks burned " PL202 thing.

here are the links for the photos just in case.

The PL202 component is an inductor. It stores electric energy and release it to the circuit.

According to your photos, your laptop may continue to work, but I recommend you to consider replacing the inductor to avoid problems in the future.

Good luck
Thank you

Hello, by far everything seem to work as normal as before. I have an eye on my temperature ever since i powered on the laptop. Would look forward to replacing the PL202 soon, hopefully. Thanks!
