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.
Step 5: Remove Plate Connector
My case was that the back of hinge had place to pop up.
Very gently slide flat drive in and gradually lift it until the plate pops up.
Reverse the laptop and remove the plate connector.
Remove the cables and plugs attached to the plate.
The mechanisms how plate connector is affixed to body of the computer varies.
Some manufacture is more difficult than the others.
Do not force pulling the plate out.
Step 6: Keyboad and LCD
I could not figure out how to disassemble further and it took 30 minutes to find out that I needed to remove the keyboard. My keyboard was fixed with double-sided adhesive pad.
Then you can remove LCD cables and antenna. Unscrew the real hinges and remove LCD.
If you have antenna, make sure which cable was attached to which.
Step 7: Remove the Exoskeleton
Step 8: Remove the Endoskeleton
Step 9: Desoldering Old DC Power Jack
Desolder your old DC jack following the This Guide "How To Desolder Components""How To Desolder Components"
Another and much better guide to desolder and re-solder a power jack is DC power jack repair guide. Do-it-yourself instructions. The credit goes to Laptop Freak.
I did not use desoldering pump. Instead, I bought desoldering braid from RadioShack for about $5. Soldering before desoldering works pretty well, though.
Step 10: Soldering New DC Power Jack
Place the new jack, solder the legs.
Step 11: Reassemble
Before placing endoskeleton, you need to clean remaining thermal compound from CPU heat sink with 90% Isopropanol and add new drop of thermal compound.
Reassemble the rest of laptop computer. Make sure all the cables and connectors are placed back. It is arduous to open it again and reconnect.
Step 12: Relish Your Victory
Relish your victory now.
