its there for something or other so obviously not good if its broken off

could you solder a new capacitor on?

Missing capacitors will increase ripple on whatever supply rail it was on, which could cause stability issues and will accelerate aging of the remaining capacitors, possibly leading to premature failures. If you can put the missing capacitor back on, I would recommend doing so. If you cannot trust yourself with soldering in whatever area the capacitor fell from, then you may be better off leaving it alone.

I know how to solder, but in this case it it very dangerous. The capacitor canoe off without the pins and 1 out of 2 of the pins are missing.

then it may be too difficult to solder a new one one

Plus the capacitor that came off does not have a voltage number on it but the other ones on the mobo do, why?

Hi, depending on the capacitor, sometimes you can use the laptop without problems. Can you provide a picture of the area where the capacitor is located and what is the make and model of your laptop?

Next to the capacitor, can you read a number like C50 or PC100, this is just an example.

From the number you gave me, it is an aluminum electrolytic capacitor of 100 uF 16 VDC.

So is it a bad thing its broken? I put it back but only one pin is going in the capacitor and the pc seems for work fine, i put it back together.

The capacitor is used to filter the 5VDC for the USB ports.

oh ok, there are only 2 usb ports near that capacitor, what will happen if i use them.

Should work fine, at least for the time being. No guarantees about long-term reliability or stability. If the original designers put the capacitor there, there must have been a reason or otherwise it would have been cost-optimized out of the design.

Depending on the device you connect to the ports the data could be corrupted.

Hi guys I'd like to know what was your reason for the initial take apart, was your PC shutting off or performance issues.
