Recently i flew with my computer on an airplane. They must have been rough with my computer as all the fans plastic pins ripped off and the fan fell on the motherboard. Now the fan i can jimmy back on with wire...but the motherboard sustained only one bit of damage...a capacitor was ripped off. the leads are still on the board so i fear i cannot use the same one as the vacuum may be gone. I am trying to find a replacement but had little luck...can anyone help? id rather not order a new 200$ board.... Its a
Asus P5Q-E Motherboard aka
ASUS P5Q-E ATX LGA775 P45 DDR2 3PCI-E16 2PCI-E1 2PCI SATA2 Sound GBLAN eSATA 1394 Motherboard. I will post a picture of the capacitor as well. Any help what capacitor to get and where would be great!! thank you.

Did you talk to a representative of the airline company? That's pretty brutal of them. Did you list your bag as being fragile? With as tight as computers are made these days, this is pretty rough. Surprised more isn't damaged.

As for the cap, I'm not sure what others think, but you might be able to solder on some leads to the existing terminals and then buy a replacement capacitor to solder onto the leads. I've never repaired a motherboard, but a lot of the PCBs I've built/fixed, the pads have been large enough to de-solder and then put a new component in. I realize that is probably impossible with a manufactured motherboard.

In response to what cap to get, that is an aluminum organic polymer capacitor. Mouser Electronics sells them pretty cheap. I am not familiar with the labeling convention of these caps, but I do know you need a 6.3V rated cap. Most likely, a 560uF will be just fine as I think that's a 561 in the picture. Here's the link to the search I did:

Yes i thought about trying this however i searched the web for a similar capacitor....but since i can only read the voltage and dont know the other specs...i cant figure out what capacitor to order>< Any suggestions would be great.

And as for the airlines it was fragile but they make u sign something when you put the tag on that waves them of responsibility:P
 
Whoops, edited it after you replied, haha. That really defeats the purpose of paying extra from the fragile sticker.

Any professional electronic store should have it. They cater a lot to the industrial environment. might even find something at radio shack. Its a maybe considering the board is SMT.
 
Which ever ones you buy, just make sure it's surface mount as tremmor mentioned and not a through hole connection.
 
I just did this a few weeks ago. The way that I understand it is if you can not find the exact match to the capacitor you can go over the specs a bit and it will be fine.

It would be best to remove the leads from the capacitor that has been ripped off and replace it with the new cap. I had a lot of trouble removing the leads so I just bent the leads of the new cap around the leads of the old one and solider them together. Just be sure to match the polarity of the new capacitor to what the old one was set to. I think the colored red side is negative?
