minor surgery on the CF-72

For the last few weeks the power socket on my CF-72 notebook has been shorting out. Not only does this allow the battery to lose its charge, but because it is a short, it gets quite warm as the connection breaks and reconnects.

It needed to be repaired before it actually melted the power cord or started a fire, and I was about to purchase a replacement on ebay for $10 when I remembered that I had a spare CF-72 chassis with a fried mainboard. I dug it out and sure enough the power socket was in good shape. My soldering skills have never been very good, but luckily this job did not require much precision. I do not have a desoldering iron, but I was able to remove the the sockets by melting the the solder on the three tabs while simultaneously prying the socket away from the board with a tiny screw driver.

Reattaching the good socket to the mainboard of my computer was a bit trickier. Because I was not able to remove all the solder from either the socket or the three holes that the socket tabs go through, I was forced to slowly work the tabs through the holes while melting the solder at each hole sequentially. I periodically dripped some alcohol in the socket to cool it, and after melting the solder and pushing the socket a little farther each time at each tab I was able to get it all the way down on to the board. I was concerned that I may have applied to much pressureĀ  or heated the board up to much, and was a bit nervous until I had the computer completely reassembled and powered on.
