Nevim, jestli ti to pomuze, ale jak u Lenova, tak i u Toshiby pisou, ze to je problem s BIOSem.
U Toshiby pisou:
The BIOS will not utilize the product key it shipped with.
a u Lenova:
It appears the BIOS is corrupt and will not utilize the product key it shipped with.

A vzdy je akorat doporuceni volat prodejce. To mas co za verzi, koupenou s PC, nebo nejakou extra..?
Protoze co si pamatuju, tak ty N verze jsou bez Win Media Playeru.
