Paso 1 Power Capacitor  ¶ 

  • With the motherboard out of the tray, let your soldering gear warm up and get a desoldering braid.

  • Since this isn't a Optiplex GX260 motherboard, I have removed the heatsink to get rid of any confusion.

Paso 2  ¶ 

Take note of which way the positive lead marker on the capacitor is facing before removing it. You will need to know for the next step.

Paso 2  ¶ 

  • Take note of which way the positive lead marker on the capacitor is facing before removing it. You will need to know for the next step.

  • Desoldering can damage motherboards, so first practice on a board you don't need. Use a 40-50W soldering iron with a chisel tip and 0.080" wide desoldering braid. Also helpful are rosin flux and 60/40 tin/lead solder, in case all the solder doesn't come out. Wiggle desoldered leads to verify they're free, and never pull on any that aren't.

Paso 3  ¶ 

Install the new capacitor in the holes left by the old one, then solder it into place.

Paso 3  ¶ 

  • Install the new capacitor in the holes left by the old one, then solder it into place.

  • Caution: Ensure that the new capacitor is inserted with the positive lead mark facing the same direction as the old capacitor. If the direction is switched, the new capacitor will fail.
