I had a laptop problem. Toshiba Lapto Satellie. May be power loose connection-doesnot charge battery, the computer can not on on AC power. 3 years old so already out of warrenty. To solve the problem I am trying to get serial number. But unfortunately it is erased. I did product registration but When I called customer serivice they could not find anything under my name. Tried w/ Best Buy with whom I bought they also couldnt. WOndering how I can find the serial number and product number.

Hello masingh,

Normally Serial number is on the back of the most of the laptops. S/N tag number I think.. Have a look properly..

Its on the sticker at the back.

The serial number at the back is erased. Thats why I am having problem finding it.

masingh, assuming Toshiba's help and support feature that comes with Windows XP (and assuming you have XP) is similar to that of HP (the one I am using right now), you can find your notebook's serial number by following these steps:

1. Click "Start" button
2. Click "All Programs"
3. Click "Help and Support"

You will see the notebook's serial number along with few other information about your notebook on the top left pane of the dialog box.

Hope this helps. Let me know! :)
