The Compaq CQ50-115NR is a notebook computer that shipped standard with the Windows Vista Home Premium operating system. The CQ50-115NR was available with 3 gigabytes of memory and a 200-gigabyte hard drive. Weighing in at less than six pounds, the CQ50-115NR has a 15.4 inch screen and full-size notebook keyboard. Rather than providing recovery disks, which are used to restore the CQ50-115NR to its factory state, the computer has a recovery partition integrated into its hard drive. To return the computer to the condition in which it was shipped, use the recovery partition.
