My Toshiba has no serial number on the bottom

posted in: Miscellaneous | 24

I bought a Toshiba Tecra M2 used from someone on craigslist. (Won’t return my phone calls) When I tried to buy a startup replacement disk from Toshiba, I discovered to my horror that there was no serial number on the bottom of the computer and the serial number was also gone from the applications menu. The Toshiba people didn’t have any other ideas about how to find the serial number and taking it to a repair shop is way too expensive. Is there another way to find the serial number, and can I get any support if the computer was stolen? The XP Pro software has a virus that no one can locate and I need to reload everything for the computer to be useable again.

To the best of my knowledge, on Toshiba laptops you can find the serial number in two different places. The first place would be the sticker on the bottom of the laptop. The second location is the DMI string. Each Toshiba motherboard should be programmed with a DMI string and this string has information about the laptop (model name, part number and serial number). Unfortunately the utility for writing/reading the DMI string is not available for general public, only certified Toshiba technicians can access it. If you want to find the laptop serial number, you’ll have to go to an authorized Toshiba service center. If the serial number has been erased from the DMI string, I don’t know any other way to find it.
By the way, if the DMI sting has been programmed with a wrong model name you’ll get a “Wrong Machine” message when you boot the laptop from the recovery DVD and start the recovery process. I believe the utility for writing a correct model name into the DMI string is available for download (for some Toshiba models).

    I bought a Toshiba laptop (model s5009b) at Fry’s Electronics back in 2010, well it’s been a year and the serial number wich is underneath the computer ofcourse wore off,
    the computer broke down it doesn’t turn on,it doesn’t charge the battery no lights at all; well I have the 2 year warranty I had bought and took it down to FRY’S ELECTRONICS and now they’re saying they can not help me because there’s no serial number when I have all the paper work for the Item, this just p…z me off and the money I spent on the extended warranty just flew away out my pocket.

  2. I have a Toshiba a665-s6098 Laptop , I bought this from ***’s advertised with back light Screen and keyboard , not so
    I have found it impossible to stay online without being plugged in . I have looked all over for the PIN # with no luck , called support since it is under warranty and they tried to get me to pay close to $300 for more warranty.
    I have tried so many ways to get WiFi to work , when I do get it to work it only last a few days before I have to plug in and go threw hours of Grief, eventualy I usually get the Grayed out WiFi to turn on. Why is this such a problem ? The Battery last almost a 1/2 Hour on eco before it’s dead, do I have a Lemon ?

  3. I have a Toshiba T4400sx and it has a password that is in the BIOS as I remember I need access to it to change the password..I sort of remember an F2 or something that gains me access.
