I want to know my model number for my toshiba laptop using my serial numbe

serial numbers are useless unless manufacturer is known
If you take it to a good bike shop, they may be able to identify the manufacturer from the joiners used in the frame and the style of the design of the bike

Toshiba is a popular name in the world of technology, and the printers, servers, desktops and notebooks the company makes are widely used in both homes and offices. While most of the time these Toshiba laptops will run without problems, there are times when laptop owners will need to take their computers back to factory new condition. In order to restore your notebook you will first need to get a copy of the recovery disk.
Turn the laptop over and locate the serial number label. The serial number label should be located on the bottom of the case. Open up the laptop and look for the model number. The model number should be located along the top of the keyboard. If the model number is not listed there, look for a model number label on the bottom of the case. Call Toshiba tech support at (800) 457-7777 to order the recovery CD. When calling, you will need to supply the representative with the serial number of your unit. You will also need a credit or debit card to cover the cost of shipping. http://laptopforums.toshiba.com/t5/Drivers-and-Utilities/Restore-disk/m-p/49692 Hope this helps.

There are a couple of ways to do this. First, there should be a product and/or serial number on the charger itself. You could google these numbers. Also, sometimes, when you remove the battery there is more info about the laptop. Maybe the label where the serial number is unreadable has a readable produst number example (p/n). Lastly, often the replacements from the manufacture are expensive. You can get a universal charger at someplace like Best Buy for around $60.00.
One more possibility. When you turn on your computer, it may have some information about the computer on the screen before it boots to windows. You may be able to go into setup and se the model of the motherboard which could help in your search.

Here is all of the information I found on the Toshiba website:

Model Name: Satellite A215-S5822 Product Category: Portable Model-Part Number: PSAFGU-04W002 Serial Number: 28093757Q Registration Number: 14117023 Purchase Date: May 01, 2008

Just upside the laptop...at the bottom you will see th model number near to the serial number
You can try the below link..go there enter the part number and serial number to get the detials of the product.

I checked on the toshiba website. The model name is Portege and the model number is 3500. There are only 2 models of this laptop the other one has the model number 3505.

What you need is the model no. You can then go to the toshiba site and put that in and it will list you the various categories of parts with the part number.
