What should I do before starting a recovery process on my HP Laptop PC 15 Dw3000?

HP Recovery Manager does not automatically provide backups of your personal data, so you must back up any personal data you want to retain before beginning recovery. Additionally, if performing recovery on a tablet, the battery must be at least 70% charged before starting the recovery process. For tablets with a detachable keyboard, connect the keyboard to the keyboard dock before beginning any recovery process. (Page 7)
