How do I perform a factory reset on my HP Laptop PC 15 Dw3000?

Use the Factory Reset option from HP Recovery Manager or HP Recovery media. Insert the recovery media and restart your computer, then follow the on-screen instructions to proceed with the factory reset process that restores the system to its original factory state by deleting all information from the hard drive and re-creating partitions before reinstalling the operating system and software originally installed at the factory (Page 5).
