When ever you get problem with your desktop or laptop you need to call the customer care to resolve it and in turn you need to provide the serial number of your system, without the serial number of your system the customer care person will not even register your problem. If you are using desktop you can easily find the serial number at the back side of the system and if you are using laptop you can find the serial number at the base of the laptop with a sticker with serial number and barcode.
But imagine the situation if the serial number sticker has been removed or the data has been wiped out, what will you do. Don’t worry there is an alternative way to find out the serial number of your PC or laptop easily. I am explaining here for Windows based system and Linux based system.
