How to Replace a Capacitor on a Computer Motherboard
Remove the damaged capacitor. The capacitors junction point is on the bottom of the motherboard, so it needs to be removed to access the underside. Using your soldering iron, heat the existing solder at the junction point for each (usually two total) leg of the capacitor. Then, gently pull the capacitor away from that leg on the top side of the ...

Got Bad Capacitors? Here''s What to Do!
When this happens, the shell explodes! Capacitors can ALSO fail if their voltage exceeds their rating. Increased voltage can damage the capacitor if is too far above the rating. Increased voltage can also cause damage if it goes on for too long a duration. Aluminum Capacitors are one of the few electric components that use liquid to operate.
