Since your new to soldering, practice soldering on some broken electricals, like for example, i opened a broken ps2, and practiced soldering on that, once you feel you are confident (it will usually be less than a few days)
If you are just starting soldering, dont solder to the mainboard, you could break it and they cost alot
the first time i soldering, it was bad, because i hard to learn that ^^^ method the hard way, by trying the usb charge, the breaking a fuse, then trying to bridge the fuse and it ending up destroying the mainboard
it was a truely sad day for vindicta
