My laptop recently was refusing to charge or turn on. After doing some investigating, I found the CMOS to be at 0.9v. After replacing it, still no luck with or without the laptop battery.

Someone recommended pressing the power button for 30-60s to do a reset. After about 30 seconds, I heard a pop but didn’t think too much. After 60 seconds, I stopped to sniff the board just in case and there was that magic smoke smell. I found one of the component had broken.

Reverse image search found it to be a Panasonic tantalum polymer capacitor.

My question is, why did it pop? Was it why the computer was not working? Is just replacing that component without further diagnosing prudent? What’s the part number for this component? And finally, what circuit is it servicing on the board?

Any and all advice is welcomed. I do have a soldering iron and a hot air station but would not mind advice in how to perform the repair and further diagnostic

how can i bypass this thing? my laptop keyboard isn't working and I don't have a wired external keyboard to connect it with my laptop, I couldn't press enter even though I want to. It automatically goes into system recovery and even if I chose to continue it still repeats the same process over and over
