Lenovo ideapad motherboard's capacitor Solved/Closed

Question

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.

Hi,

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

The exact same happened to me, I was installing a 8gb ram and after i put the metal it burned the capacitor! I wonder if there are any long term problems with you guys? Mine is working fine but i recently bought the laptop and im concerned...

The PL202 inductor is not a critical element for the laptop to work. However, because each component is necessary to the circuit, and is not there just like that, leaving the damaged inductor leaves a risk that the laptop will fail or malfunction at anytime, even if it continues to work properly now.

The best thing to do is to replace the inductor to be sure that no hardware issues will occur in the future. I invite you to contact Lenovo for help in order to replace it.

Now if you continue to use your laptop, you should keep an eye on the temperature and run hardware diagnostics periodically using Lenovo Vantage. I also recommend that you back up regularly your personal data on an external hard drive, just in case.

Good luck
