Sony vaio vgnfz280e b

End users can at best expand memory or disks (hdd/SSD) on Notebooks from internal hardware perspective.

In my humble opinion, the motherboard of any brand laptop, notebook computer are highly integrated and the video is very much a part of it that cannot be replaced. At best you can try different video settings and perhaps even a different driver version if available.

Want the manual for sony vgn-n38e

Link to the Service Manual, Donald,

That Sony VAIO VGN-N38e, is part of the Sony VAIO VGN-N series of Notebook PC's.

Scroll down to the 8th line that begins with the blue -> VGN-A
Scroll across, and click on the blue -> VGN-N

PDF file. and the computer you are using now has Adobe Reader on it, which uses PDF files.
May take up to 30 seconds after you click on the file name (VGN-N), before the first page comes up.
The file is downloading in the background.

That is the Service Manual. It doesn't have board level component replacement.

Is there a board level component that you feel needs replaced?
What are the symptoms of the laptop?

Power issues, if not the AC adapter, (Charger), or DC Power Jack; are related to the Power MOSFET's on the power circuit of the motherboard; and may also have bad MLCC's in that circuit.
(Multi-Layer Ceramic Capacitor)

[DC Power Jack is part of the circuit. Where it is attached look at those P.MOSFET's.
Example using HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's,

These series of HP's use the Fairchild Semiconductor International - FDS6679 - Power MOSFET, and the Alpha & Omega - AO4407 - P.MOSFET.

Looking at the second photo down, with the AO4407 circled in Yellow; look at the small rectangular object to the immediate right, that has a wide dark band on it.

There is one above it of the same size, and one above that one.
There is also one to the right of the top one.

These are MLCC's.

Scroll down.

AO4407 has been phased out. List shows cross-references.

Just 4.7Mfd examples at 16 Volts.
Do not know the values of yours ]

Electrolytic Capacitor/s replacement?

OH, just cleaning the laptop out?
S'okay I was just letting you know board level replacement is possible.
(Does kinda' depend on your de-soldering/soldering skills, though)

How do you remove the keyboard on a Sony Vaio laptop PCG-7192L

Let's see if this helps Tom,



The Keyboard Cable STAYS attached to the Keyboard.
It disconnects FROM the motherboard's connector.

The Keyboard Cable has NO connector on the end. It is a FFC.
Flat Flex Cable.
One example of a Flat Flex Cable,

The flat metal terminal bars MUST be aligned back in the SAME position, as they were originally.
For this reason you may wish to take a Sharpee marker, and make a mark on one side of the cable.
Then make a matching mark on the same side of the motherboard connector, BEFORE you remove the cable.

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

The bottom part is larger, rectangular shaped, and is stationary to the motherboard.
It is the BODY.

The upper part is smaller, rectangular shaped, and is movable.
It is the Locking Bar.

ACCORDING to the video the Locking Bar is the Slide/Wedge type.

DO NOT use a metal tool as shown. One slip, and you can damage the motherboard! Geez!

Use your Fingernails, or Thumbnails.

The Locking Bar slides up. Up towards the LCD screen, or away from the Body.
It ONLY moves about 2mm. That is a little larger than 1/16th of an Inch.

IF, the Locking Bar is broken, or the Body, you are looking at

Hence why I am being so detailed.

More detail on unlocking this type of motherboard ZIF connector,

A) Locked position;

B) Unlocked position;

There is another style of Locking Bar used, however.
The Locking Bar flips up to a 90 degree position, or also can be stated as Straight Up.

Just to make sure I'm going to include info for it too;

A) Locked position

B) Unlocked position;

For additional questions please post in a Comment.

Carrying the laptop from the left side freezes the screen. Nothing wrong with the hard drive. Possible shorting somewhere?

It sounds like a poor connection on the motherboard to screen cabling.
Get an authorised Sony repair service centre to take a look at it.

I've broken the headphone jack input socket on my Sony PCG-7L1M laptop. Can I seperate the key board or split the body to gain access to it from inside. If so can you please tell me how?

No ken1517 you have to completely disassemble the laptop down to the bare motherboard.

The PCG-7L1M Notebook PC is one of the Sony VGN-FS series of Notebook PC's.

Here is the download page for the Service Manual (Free)

Go down to the bottom line that starts with > VGN-A
Scroll across, and click on VGN-FS

This is a PDF file. May take as much as 30 seconds after you click on the above file link, to see the first page. May take additional time to fully download.
Suggest you let the file download all the way before looking through it.

1) Buy and wear an ESD wrist strap, and connect the alligator clip to a good ground source.
(Electro Static Discharge)

I connect to the metal frame of an empty desktop computer case.
You should wear one because your body carries Static electricity. Static WILL fry out (Short Circuit) the hardware components inside a computer. The ESD wrist strap, and connecting to a good ground source, will relieve your body of Static.

The average cost of an ESD wrist strap is $3 to $6.

2) Remove ALL power before you begin.
Remove the AC adapter (Charger) and Battery.

3) Use a multi-compartment container for the various screws you will remove. Mark each compartment for the areas the screws come out of.

There may be as many as 60 screws and 12 different types.
Do Not mix them up.

4) Make notes and drawings as you disassemble. It's nice to have a record to go back to in case you get interrupted, and a Service Manual can only take you so far.

Use a camera, or video cam if available. Use good lighting.

5) Remove the Fan/Assembly and Processor, Ram Memory, and Wireless Module from the motherboard. You want just the bare motherboard in your hand. (You have removed everything else to get to the motherboard)

A Processor is HIGHLY susceptible to Static shock, and so is the Ram Memory. You don't want to be de-soldering/soldering with ANY hardware components on the motherboard.

6) I suggest using .050 Rosin core solder, and a 40 to 50 Watt soldering iron. Keep a damp sponge handy for frequent cleaning of the soldering iron tip, if you don't have a soldering iron stand with a sponge in the base.

I also suggest using Desoldering Braid, (solder wick), instead of a Desoldering Tool. (Solder s-ucker tool)
A lot easier to de-solder with.

Make good clean solder joints. You don't want a cold solder joint, and have to disassemble again.

Do Not linger too long when soldering, or you can burn the area on the motherboard you are soldering, and it won't take solder. (Circuit trace. The copper strip, or area around a hole) {You won't be able to tin the area with solder}

Need advice shoot me a Comment. (Believe upper right of your page)

The headphone jack is a type of TRS connector. (Tip, Ring, Sleeve)
You'll have to look it up on websites that offer TRS connectors, or hit up your computer repair shops in your area.

I need to know the pixels for a sony viao vgn-430d screen

You should be able to find the proper LCD screen, by the LCD screen size, whether it is a widescreen or not, and whether or not it's a matte finish.
I need the exact model number. The Vaio VGN-430d does me no good. Suggest you look on the bottom of the laptop. There may, or may not be a Service Tag.
Look for something like VGN-NR , and a number.
What you may see on the side of the LCD screen, or on the body of the laptop, is just part of the VGN series.

Help me please

You should get the motherboard model. There are a lot of motherboards carrying the same chipset so it is hard to determine the pin configuration. A chipset is the main chip used by the motherboard. Other motherboards could use is as well.
