NOTE: You, the customer, are solely responsible for data security. WinBook strongly recommends that you perform a backup of all personal data contained on your system prior to performing this procedure. Warning: WinBook will NOT be held responsible for any data loss incurred during this process.

Most WinBooks will use the same format for the serial number. Exceptions to this are listed below. If you have difficulty finding the correct number, or if the number is not readable, please note in your e-mail all of the numbers on the bottom of the unit. Sometimes RAM numbers and other reference numbers can be used to find the purchase information. If there are no stickers, we sometimes can look up the invoice under the original purchasers name. For all retail units, Please include the owners name and as much information as possible, since we cannot access those units by serial number.

The standard format is a 14 digit code: a 6 character configuration code, followed by a single letter indicating the place of purchase, then a 7 character build code. The first letter of the code indicates the model of the computer.

WinBook XP: A, B, C, D, E

WinBook XP5: F, G, H, K

WinBook LM: P

WinBook XL: R, S, T, U, Y, B, D

WinBook XLi,: V, W, Z

The location code indicates where the unit was purchased (the 7th character in the number).

W: Purchased by phone or website order directly from WinBook. These records can be directly accessed using the serial number.

D: Shipped directly from the factory in Taiwan. If there are no other characters after the D, then use the other number (see XL/XL2 exception below).
