SOURCE: how to replace power jack on sony vaio pcg-k33

Short version?

1.Remove the AC adapter if plugged in, remove the battery.

2.Wear an ESD wrist s-trap, and have it connected to a good ground. Work on a table, have a container with multiple compartments for the screws, and mark where each screw came from. There are as many as 65 screws, and 8 different sizes.

3.Completely disassemble the laptop, down to the bare motherboard in your hand. Remove the LCD screen assembly. No Processor, Cooling Tube, Heatsink, Ram Memory modules, CD/DVD drive, Harddrive, Wireless Antenna module, Keyboard, Nada!

4.Buy a replacement DC Power Jack.
Here is an example of one,

http://powerjack.us/index.php?main_page=advanced_search_result&search_in_description=1&keyword=Sony+Vaio+PCG-K33

5.Use the correct tools.
If you're a really experienced tech, you can use a 30 to 40 Watt soldering iron. No.2 tip. Have a clean damp sponge nearby, to constantly clean the tip.
Make sure the tip is clean and tinned correctly.

Or use a medium priced soldering station.

I advise using soldering wick, (Desoldering Braid), instead of a Desoldering Tool. Works much better.

5.Use the correct soldering procedures.

Linger too long when heating up the solder joint, to remove the DC Power Jack, and you stand the chance of burning the board. (Motherboard)

Also could lift the Circuit Trace right off of the board.
(Circuit Trace may be thought of as a very thin, copper wire on the motherboard. It isn't, but this explanation will do)

Do any of the two errors above, and you can use the motherboard for a Frisbee.

My method for removing the DC Power Jack, is to pull up on one lead at a time. Use constant pressure with my finger, and thumb. (Don't get 'Godzilla' on it. It can break. Everything has it's limits!)

I heat the solder joint for that one lead, and try to pull it up, a little out of the board. Then I move over to another lead, heat it, and pull up slightly on it. Keep moving from lead to lead, until finally they start pulling out.

After the jack is removed, the area needs to be cleaned. I use 90 percent Isopropyl Alcohol, and Q-tips.

CAUTION!!!!
This is HIGHLY FLAMMABLE! Keep it away from that hot soldering iron, and use in a Well ventilated area.
Always immediately return the cap to the bottle, and tighten the cap well.
Have fire precautions ready, just in case an accident happens.
Better Safe, Than Sorry!

The area of solder, around the hole in the board for the jack, may need to be buffed off. (Fine sandpaper in a tight roll, or a fingernail file using the fine side)

All areas that will accept solder need to be clean, and tinned.
Tinned, ...is the area is cleaned, a light spot of flux is touched around the rim of the hole, then solder is applied. The hole's rim then has fresh solder around it, and is ready to accept the DC Power Jack lead.

Be sure you have good solder joints! You may not see a cold solder joint, until you put the laptop back together, and the jack doesn't work. Then you get to take it all back apart, look at your solder joints, and go "OH".

This may help you in disassembling,

Put the cd in and restart. If it doesn't give you a message to press "x" to boot from cd, then you need to chage the boot order in the BIOS.

To get into the BIOS, restart and press del or F2 (it might say something on the screen like press del to enter setup) that is the BIOS.

Change the boot order to CD first.
