    Well...took the entire damn laptop apart. Couldn't get to the jack...soldered into place; had to get the motherboard out; ordered the part (apprx $20,incl shipping). Geek Squad quoted min of $200 plus parts, thought that was outrageous until I now realize how much time it takes to pull out all the components/screws, etc. Hopefully, all I'll have to do is pull the old part out, and put the new part in (plus solder into place). Doesn't appear as though anything else "bad" no scorch marks, and hopefully no damage to motherboard. You'd think that these things would be put together in a way that makes em easier to replace parts (but that probably doesn't make money for the manufacturers). Anyway, thanks for the advice! It's very much appreciated!!!! Thanks, JLL

Hi there generally all laptops can be opened more or less in the same way first undo all screws in the back, next you need to remove the panel where the power button is most of them just unclip and come off easily using a flat screw driver, you'll probably find some more screws underneath,if the hinges covers are part of the panel they should come off with the panel if seperate just check for any screws if not they just unclip undo any further screws, next unscrew the keyboard, unplug it, unplug the mouse pad, then the top part of the laptop base should just lift easily, make sure you remove the battery before you start all this, any drives, hard drive, etc hope this would be of some help regards

Sony vaio pcg 7184l system does not power on

That's why I always tell people;

1) Install the Battery
2) Connect the AC adapter (Charger)
3) THEN connect the AC adapter to power.

AC adapter disconnected, remove the Battery.
Press the Power On button in, and hold it in for a count of 10 seconds.
(And I mean 10. Count, 1001,..1002,..1003,..1004, etc)
Let go of the Power On button.

Do this procedure 2 more times.
What we are doing here is clearing CMOS Error Codes, resetting BIOS setup back to the factory default settings; and resetting sensor values in the power circuit section of the motherboard.

Now reinstall the Battery. Reinstall the AC adapter. Plug back into power. WAIT 1 minute, turn the laptop on.

Still no?
Suggest we have a problem Houston.

Power MOSFET's in the power circuit section of the motherboard, or may be just a bad Power On switch, now.

Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.

Look at the motherboard where the DC Power Jack is mounted.
(The DC Power Jack is where the AC adapter plugs into, on the laptop)
You'll see Power MOSFET's, and MLCC's surrounding them.

This is an example using HP Pavilion dv6000 series, and Pavilion dv9000 series, of Notebook PC's,

Uses a Fairchild Semiconductor International - FDS6679 - Power MOSFET, and an Alpha & Omega Limited - AO4407 - Power MOSFET.

Looking at the second photo down with the AO4407 circled in Yellow;
Look at the rectangular smaller object to the immediate Right; that has the dark wide band across the middle of it.
This is an MLCC.

There is one above it, one above that one to the Top; one to the right of the top one; and one to the right of it.
See if any of these are burned/blistered also.

Or it might be worse, Clifton,

May be time for motherboard replacement.

Sony vaio model pcg-61611L it turns on for 4 seconds and then it turns off using the ac adapter . help please

The charger may be bad, will it charge the battery? a common problem is the DC jack in the laptop breaks connection on the motherboard internittent operation or no power and shut down. If you can sub the charger that will tell if the power supply is bad or the problem is in the laptop. If the computer is the issue I recommend a professional because it will require extensive parts removal.

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,

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.

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, 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,

Would any 16volt ac adapter be ok to charge my PCG-VX89 vaio notebook?

you can use any laptop AC adapter DC output-16V and 4A (current). if its jack size natch your laptop DC jack.
if the adapter DC current less than 4A (over 2.5A at least) you should only make the battery charging without laptop turn on!!!
please take a rating let me know how much helped you thanks!

Can't seem to disassemble sony vaio pcg-grx550 laptop

try looking on the top of the laptop, around the keyboard to see if there is anything that will pop off, they are very bad about hiding more screws in places like that.

Sony vaio pcg-grx550 problem

you may have hardware problems an may need to change something inside. if you have the manual check the part of beep codes

I would like to replace the hard drive in my Vaio PCG-6F1L notebook and can not figure out how to open the case. there is one release I am missing. Bruce

Usually there is a side or a bottom part of the case where you can pop the hard drive out. My best advice is to refer to a manual or sony directly.

Vaio will not turm on

you will most likely need to replace the dc jack, which is the port where your charger plug plugs into...

To test if your dc jack is bad... Remove the Battery, Plug the Power cord into laptop then attempt to power on... If no lights turn on, no fan spins.. your DC jack is bad...
DC Jacks Cost $6 to $10 but you need to find someone experienced to replace it, or you might end up with a dead motherboard as well..

Technical information

If the adapter is working, the problem could be the jack on the back of the notebook. The nice thing is most of the Vaio notebooks the jack is replaceable without having to solder the jack to the board. I would call SONY regarding the jack for a mode number and a picture. it's easily replaceable but requires the disassembly of the notebook.


It's probably the power socket on the laptop not the power jack on the AC adapter. You need to open the laptop by removing the casing screws. Then remove the motherboard from the base so a new socket can be soldered on.
