Electrical Engineers, what is this?

This is an example of what I need to identify.

That is a surface mount capacitor.

He is correct its a SMT capacitor

Thanks guys, how do I know what to replace it with?

Whats the voltage reading with the circuit on? What part are you talking about has this cap?

 

[2GbTalonGuy]

What's wrong with it? It looks ok, not cracked or chipped anything.

Looks like it burned the solder to me, maybe try to resolder it first?

This is just an example. When my brother took apart his laptop he arced it somehow, the power was still plugged in. So it just peeled off. I want to fix it because i'm pretty good with a soldering iron. The one on his laptop is completely gone. I need to know what to replace it with. The only designation it has is a number on the board showing which one it is. The top of the cap is blank just like that one.

I've got some old junk motherboards, can I just take a surface mount cap from that? I tested one I saw that was the same size, it measured 1 ohm?? The readings were both the same.

Hmm, a good capacitor not connected to anything should read basically infinite ohms, not 1 ohm. If it is still connected to other circuitry your 1 ohm would be the resistance of some loop around the board, not the cap.
Really I don't know anything about tantalum caps, which I guess is what you have there, but that's how caps work in general.
So if you want to measure a cap, you need a good multimeter that can measure capacitance, you know, micro farads, nano farads, pico farads, stuff like that. My Fluke meter will measure caps, but Flukes are pretty expensive.
Of course you won't be able to measure a blown cap because it is ... blown.
So that's where you might be a little stuck. Sometimes caps are used just to block DC, then the value of the cap doesn't matter very much. Other times they are used to store energy or diminish frequencies below a certain cutoff freq. Then you need to use a correct value. That's about it from me - I'm a mechanical, not an electrical!
There should be computer hardware forums where guys would go nuts with this. Tom's Hardware is a good site. Good luck!
