Updating drivers
A driver is a software program that enables your computer to communicate with an attached device, such as a
printer, hard disk drive, mouse, or keyboard.
Complete the following procedure to update a driver, or to revert to an earlier version of the driver if the new one
does not solve your problem:
1. Tap the Start button.
2.
Type Device Manager into the Start Search box, and then tap Device Manager to open the Device
Manager window.
3. Tap the plus sign (+) to expand the type of device you want to update or rollback. (For example, DVD/CD-
ROM drives).
4. Double-tap the specific item (for example, HP DVD Writer 640b).
5. Tap the Driver tab.
6. To update a driver, tap Update Driver, and then follow the onscreen instructions.
Or, to revert to an earlier version of a driver, tap Rollback Driver, and then follow the onscreen
instructions.
You can also go to the HP Support website:
www.hp.com/support and select the task, Download drivers and
software. Follow the onscreen instructions.
