My new Sony VGN Z55ON Laptop not recognized the wireless card

Posted by on

    Do you mean it does not find any wireless networks, or it does not recognize the built-in or add-in wireless card? If it does not recognize the card at all, make sure you have the drivers installed.

Disassemble sony vaio vgn-b100b


1) Remove all power to the laptop.
Unplug the AC adapter (Charger) and remove the Battery.

2) I suggest you wear an ESD wrist strap. Connect the alligator clip of the ESD wrist strap to a good Ground source.
(I connect the clip to the metal frame of an empty desktop computer case)

This is an example of an ESD wrist strap,
(Electro Static Discharge)

http://www.hotdealshop.com/html/productOverviewNew.aspx?prdId=23733FR030910

You can see the price of this one is under $4.
Perhaps some 'Mom and Pop' computer repair shop will have one.
Maybe cheaper.

Reasoning for ESD wrist strap;
Static electricity.

Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.
(Some examples: Processor, Harddrive, Ram Memory, Graphics Card, or GPU, etc.)

The ESD wrist strap will relieve your body of Static.
(If a person's budget will not allow this expenditure, you could fashion a homemade version)

3) There may be as many as 60 plus screws, and 10 different types. Do Not mix them up!

Some of the screws look to be the same size, and have the same thread. Nope!

Use a multi-compartment container for the various screws you will remove. Label each compartment, for the area of the laptop that you removed the screw from.
You can use a clean egg carton in a pinch, and label each egg holder.
(I work on laptops, and use them anyway. Saves on cost)

4) Laptops are disassembled from the top going down. There is no removing just the bottom cover.

If you are going to completely disassemble the laptop, the LCD display assembly will be removed first.

Then the Keyboard/Hinge Cover. (Plastic strip above the Keyboard, and below the LCD screen)

Next Keyboard, static Shield Cover, and then you can access the internal hardware parts.
(Processor Heatsink Assembly, Processor, and so on)


A) Service Manual (Free)

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-sony

Under the heading Sony, go down to the bottom row.
Begins with VGN-A
Go to the right, and left-click on VGN-B

(The Sony VAIO VGN-B100b is one of the VGN-B series)

This is a PDF file. Give it a few seconds, and it will download.

(Watch the download progress bar, let the file download all the wat before looking through it.

The computer you are using has Adobe Reader on it. Adobe Reader uses PDF files.
The file will automatically download, and open.

If you do not have the latest version of Adobe Reader, suggest you upgrade. Adobe Reader 9.3.4. )

The above free Service Manual has photos, and instructions.
Not as concise, and clear as I myself, would like, but you may find it to be a useful resource.
You can save it to your computer, and burn a copy off to CD disk.

This link also has photos, and instructions, but is for the Sony VAIO VGN-BX.

It's a step by step, with clear photos. You can left-click on each photo to enlarge them.

Should this be your first time disassembling a laptop, or a VAIO VGNB100b, you may find the above useful.

I don't have the schematics for the Sony Vaio VGN-N series laptops, but I can provide a link to the disassembly instructions,

Scroll down with your eyes to the bottom line of listings in blue.
The line that starts with VGN-A
Scroll over to - VGN-N, and Left-click on it.

This is a PDF file.
You may have to wait up to 30 seconds, before you see the first page come up.

If you are hardly doesn't connect even your wireless station is been detected why not try to set your settings manually in your wireless card.

This is when you are behind a router.

Goto Network and sharing center. Click on Manage Wireless Network. Click on Adapter properties. Click Internet Protocol version 4. Click properties, then set the ipaddress of your laptop it doesn't have to be identical to any of your existing connection, your subnet, default gateway. And also input your IP DNS.

I have sony vaio VGN-CS12GH so can i use graphic card in my laptop.


The graphics circuitry is integrated into the motherboard in a laptop and you can't install a different card. If you are looking for a way to improve graphic performance, your only option is to download the latest video drivers from either the computer manufacturer or video chipset makers' websites, and see if any new capabilities have been added.

One of the laptops we are using on the wireless modem/router is not detecting the modem even though it has been installed as instructions, whilst the second laptop that we installed the adapter onto is...


Let me make sure I understand the issue. You have a wireless adapter that works on one laptop but not the other? If so, blow out the card slot on the defective one with compressed air. Make sure it's firmly in place while the machine is off. So when it's clean and firmly in place, now turn it on. It should recognize and come right up.

If not, you may have to reinstall the device. I mean the actual slot. remove the wireless card, Right click on my computer and hit properties. Hardware tab, then device manager. Find the PCI slot in the list and delete it. reboot the laptop and it will automatically reinstall the slot. after it says your new device has been installed and is ready to use, put the wireless card in and it should work.
