This instructable does not require advanced soldering/desoldering skill. I had never desolder anything before, but was able to somehow desolder the jack.
The problem kept coming back. So I did permanent fix using modem port in my latest instructable.
Step 1: Initial Diagnostics
The new DC jack shows how it is supposed to be.
Step 2: Materials required
1) Soldering iron (25W)
2) Multimater (optional)
3) Small screw drivers: 1set
6) New DC jack*
7) Thermal compound (often used for computer)
8) Disposable cups x6
9) Desoldering braid ($5 at RadioShack)
10) Isopropanol (not RNase Free)
- New DC jack was puchased from DC PowerJacks.net
Mine was less than $7. You can google and find cheapest source.
Step 3: Most important key! DOCUMENTATION!
Look around and write down schematic diagram of your computer.
You will assign screw numbers and mark them into your figures as you disassemble.
Step 4: Disassemble 1
Remove screws and assign screw number.
Place screws into corresponding disposable cup.
Take note where and what type of screws were there.
