The input jack is just that. It connects to the system board via a cable. The power adapter jack needs to be replaced.

REPLACE POWER JACK


http://www.ebay.com/itm/pcg-41217L-sony-vaio-DC-JACK-POWER-JACK-FOR-Input-Port-Socket-vpcsc-VPCEL-VPCF-V-/370628762815

Has two channels on the sides, to slide down into a channel formed in the outside edge, of the laptop Base Enclosure. (Bottom Cover)

Wires are soldered to it. Two of them. If there is a Red wire it goes to the Center terminal on the back of the jack. The Center hole is the Positive connection.

The Black wire goes to the outside terminal on the back of the jack.
(Negative)

Use good de-soldering/soldering skills. Do not make a cold solder joint. (Solder connection)

There are no exact Service Manuals listed for the Sony VAIO PCG-41217L Notebook PC. (It is also part of the VPCSC series. It is a VPCSC31FM)

However after you disassemble 100 laptops, or so; you find disassembly of all laptops follows a basic pattern.

http://www.ebay.com/itm/Sony-Vaio-vpcsc1afm-pcg-41217l-s-series-laptop-I5-blu-rau-MS-OFFICE-installed-/271101863505?pt=Laptops_Nov05&hash=item3f1eee2651

This shows me different key views of the laptop. I have also opened a separate window, with the User Guide from Sony eSupport.

The Ebay link shows detail of the Palm Rest Cover.
Shows it to be one piece with no separate Switch Cover.

(Switch Cover: Flat plastic strip above Keyboard, and below Display Assembly.
Usually has the Power On button, LED indicator lights, speakers, etc in it)

Also shows me a Bottom View.

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Lay the notebook on a clean, static free cloth, on your table.
Helps protect the table, and the laptop from scratching.

Lay the notebook bottom side up, Battery Compartment facing away from you.

Use a multi-compartment container, and label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws. Advise DO NOT mix them up.

You should be wearing an ESD wrist strap, and have it's alligator clip attached to a good ground source.
Average cost is around $3 to $6. Do not wear it, and/or connect to a good ground source, and when you are finished you can use your laptop for a doorstop.
Static 'kills' computers.

Example of an ESD wrist strap,

http://www.radioshack.com/product/index.jsp?productId=2103245

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case. I feel an Anti-Static Mat is unwarranted.

You can set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or a large metal knickknack. (Unpainted)

You are going deep into the laptop, and the Static sensitive Processor, and other hardware components could be 'zapped'.
Use ESD wrist strap.

All screws are removed from the bottom of the laptop. All around the perimeter (Outside), and the inner ones.
The optical drive (CD/DVD drive) will slide out.
After the optical drive is removed, look to see if there are any hidden screws on the outside edge of the laptop, that may have been covered by the optical drive. Remove them if so.


Remove the Harddrive.
Remove the Ram Memory.
Remove all peripheral components. (Dummy PCI card, etc)

I don't know if the Palm Rest Cover removes on this model, or the Bottom Cover. (Base Enclosure)

Bottom Cover removal style,

http://www.insidemylaptop.com/take-apart-sony-vaio-vgn-cs215j-laptop-replaciong-dc-jack-harness/

Yes. The bottom cover access panels are different than yours.
Posted for Keyboard removal, and Bottom Cover removal.

NOTE*
The Keyboard Cable STAYS attached to the Keyboard. It removes from the motherboard. There is NO plug connector on the end of the Keyboard Cable.
The Keyboard Cable is a FFC. Flat Flex Cable,

http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpg

It ONLY plugs in, in one direction. Must go back the same way it was originally. Even if it was originally twisted.

For this reason you may wish to make a mark on one side of the cable, and a matching mark on the same side of the motherboard connector. (Sharpee?)

The motherboard connector is a type of ZIF connector.
Zero Insertion Force.
It is composed of two separate pieces, but DOES NOT come completely apart.

There is a larger rectangular Bottom part. This is the Body, and it is stationary. Mounted to the motherboard, and doesn't move.

There is a smaller rectangular piece on Top.
This is the Locking Bar.
There are two styles presently used;

1) This style slides. Slides up towards the LCD screen.
ONLY slides about 2mm. That is a little more than 1/16th of an Inch.

A) Closed, or can be said as Locked;

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-C650-C655/body-big/disassemble-toshiba-c655-11.jpg

B) Open, or Unlocked;

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-C650-C655/body-big/disassemble-toshiba-c655-12.jpg

The Locking Bar is barely seen on top, and the sides. The 'tabs' of it on the sides, are eased towards the LCD screen, with the thumbnails.

2) This style flips up,

A) Locked;

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-13.jpg

2) Unlocked;

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L645D-L640D/big/laptop-disassembly-14.jpg

IF, the Locking Bar is removed from the Body, it is broken; or the Body hinge pins are broken.
EITHER way means MOTHERBOARD REPLACEMENT, and why I am being so detailed. Use care.

Here is what the Keyboard looks like,

http://www.ebay.com/itm/SONY-PCG-41217L-Keyboard-Silver-/261121017591?pt=PCA_Mice_Trackballs&hash=item3ccc0686f7

Put your mouse in the middle of the photo, and slide to the right side of the Keyboard.
See that half-moon tab sticking out, that looks to have a threaded hole in it?
Screw comes up from the Bottom of the laptop, and goes into this tab.

Looking closer at the open laptop view of the Keyboard, it almost looks like the Keyboard is under the Palm Rest Cover, and cannot be removed until the Palm Rest Cover is removed.
May just be the view, or my eyes.

That is about as far as I can take you.
Post the problems you run into in a Comment, and we'll try to work them out together.

Wont power up no lights


Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

I have Acer Laptop with a JV50PU motherboard which has a faulty DC input socket connection. The laptop works OK on Charged battery but not on DC input. Is it possible to get a schematic of the motherb


If the DC Power Jack is soldered onto the motherboard then take the time to unsolder it and remove it. Then buy another DC Power Jack which costs less than $8.00 and solder it into it's place. Normally when it is soldered onto the motherboard there is no cable involved. That's all there is to it if it's soldered onto the motherboard.

If it sits on a slot in the motherboard and has a cable harness attached to it then you can purchase that too for less than $15.00. All you do then is follow where the other end of the cable harness plugs into the motherboard and unplug it. Then place the new dc jack in the slot where the old one sat and plug the other end of the cable harness into the motherboard.

I need a body case for my vaio vgn-nw120j/s


The panel you refer to is the Palm Rest Cover (Sony)

Covers the top of the body of the laptop, has the Touchpad in it, and the Keyboard is in the top/middle.

I would suggest going to Ebay, and looking at Laptops for Parts, or a laptop like yours that may have internal problems, or a bad LCD screen.

As for guidance in removal and replacement, I have no links to give you for this exact model.

I can however link you to guides that are similar, and should work;

1) http://www.insidemylaptop.com/disassemble-sony-vaio-vgn-fw170j-series-laptop/

The LED light/Power Button/Speaker Cover is different in shape.
(Strip of plastic below the LCD screen, and above the Keyboard.
There are different names for the various models)

2) http://www.insidemylaptop.com/replace-lcd-screen-sony-vaio-nw235f-laptop/

In case you wish to replace the LCD screen, lol!
Used to compare against the VGN-FW series, and to let you know, I know the VGN-FW series is a little different.

However after you have disassembled many laptops, you see that there is a simple specific pattern, for all laptops.

A) Don your ESD wrist strap, and connect it to a good ground source.
(Electro Static Discharge)
Average cost is around $3 to $6.

(I connect it's alligator clip to an unpainted surface, of the metal frame of an open, empty desktop computer case)

B) Lay a towel on a table. Make SURE it is static free. (Unless you have a workbench like I do, and static cover)

C) Laptop off, closed, and upside down on the towel, remove ALL power to the laptop.
Remove the AC adapter (Charger) and Battery.

D) Look on the bottom to see if there are arrows pointing to screw holes. Remove the ones indicated to remove the Keyboard, strip of plastic above the Keyboard, (If there are any), and Palm Rest Cover.

[ Use a multi-compartment container for the various screws you will remove.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder for the area the screw/s come out of.

SOME screws look VERY similar to other screws.
DO NOT mix them up.

Make a record as you disassemble. Make notes, drawings, and use a digital camera, if available, or a video camera. (Use good lighting)
It's nice to have a record to refer back to, in case you are interrupted ]

E) Turn the laptop over to it's normal position, open the LCD screen all the way back.
Pop the strip of plastic above the Keyboard loose, then remove it.
Use CARE as there may be speaker wires, and LED light wires going to this strip. If you use a tool, (plastic Spud Tool?), do NOT damage the wires. These will have to be disconnected.

F) Remove the Keyboard. There should be 2 or 3 screws at the top of the Keyboard, holding it in place, OR there were screws you removed from underneath. (Bottom of laptop)

The Keyboard tilts up at a 45 degree angle, (Lift the back, or LCD screen side), then slides forward a little. (Towards LCD screen)
The Keyboard Cable is still attached, so do not try to remove it all the way yet.

The Keyboard is Not brought up to a 90 degree angle, when removing.
There are plastic tabs formed at the front of the Keyboard, which slide into the Palm Rest Cover. These can be broken off.

The Keyboard Cable does Not remove from the Keyboard. It removes from the motherboard.
The Keyboard Cable is a FFC. Flat Flex Cable.

It does not have a connector on the end of it. It's just a few wires encased in plastic, in a ribbon shaped flat cable. The ends of the wires have a small metal contact strip.

The connector on the motherboard is a ZIF connector.
Zero Insertion Force.
It is a rectangular shaped piece of plastic, that is composed of Two parts.

A smaller part that resembles a thin rail, at the top, and a thick block at the bottom.

The thinner part slides UP, (Towards the LCD screen),
OR,
it flips up. There are two different styles.

For the style that the thinner part slides up, it DOES NOT slide out!
It only slides up just a little, to unlock the Keyboard Cable. (1/8th inch approximately)

Then the Keyboard Cable slides out.
(Be SURE to note which way the Keyboard Cable goes in! Even if it is twisted, it MUST go back in the same position)

If you slide the ZIF connector completely apart, you will have broken it, and the repair is to replace the entire motherboard.

[ Also note which way all cables are routed through the laptop. They MUST go back in the same route, or you will not get the laptop back together ]

G) You will have to disconnect the Video Cable on the motherboard side, and the Wireless Module cables on the Bottom side of the laptop.

The Wireless Module wires are then carefully fed through the Palm Rest Cover, and laid aside. (They go up into the Display Assembly)

H) Perform one last check for any cables, then pop the Palm Rest Cover loose. (It has tabs formed on the outside edges, inside the cover. These snap into matching tabs on the Bottom Cover )

For additional questions please post in a Comment.

Sony vaio vgn fw21l,loose hinge


I am a PC Technician, I also happen to own a Vaio with this cool but very fragile power button. It will be okay to leave it like that.I had the same issue and I repaired mine because I have experience tearing down laptops. The labor to get to that little plastic piece is extensive. If the situation arises I can explain to you how to do this, ill even have pictures as it is nearly impossible to find service manuals for new Vaios. But it will be fine if it is a little loose.

Sony vaio vgn fw21l,loose hinge


My hinge broke on my Sony VAIO and the solution I found was to purchase the Service Manual for the laptop then take the laptop apart and find out which part number the hinge was. Then purchase the hinge directly from USA, which took 1 week to come through and mended the laptop myself.

Sony are doing this to everyone who has problems with the hinges of the laptops as they state the guarantee covers everything EXCEPT the hinges. If you can get proof from a pc repair shop that the hinges are a design flaw then Sony will repair it free of charge, but they will still request a Diagnostic fee which will be refunded if the problem you described turns out to be true.
