Hardware Upgrades
✎
When replacing the hard drive, transfer the four screws from the old 
drive to the new one. The screws take the place of drive rails. You will 
need a Torx T-15 screwdriver to remove and re-install the guide 
screws. HP has provided four extra 6-32 standard guide screws on the 
front of the chassis, under the computer cover. The 6-32 standard 
guide screws are silver.
✎
If you replaced the primary hard drive, insert the Restore Plus! CD 
to restore the operating system, software drivers, and any software 
applications that were preinstalled on the computer. Follow the 
instructions in the guide included with the Restore Plus! CD. When 
the restore process has completed, reinstall any personal files that you 
backed up before replacing the hard drive.
Installing a Drive into the 3.5-inch Drive Bay
Depending on the computer configuration, the 3.5-inch drive bay on 
the front of the computer may be configured with a diskette drive or it 
may be an empty drive bay. The type of bezel covering the drive bay 
will vary depending on the original computer configuration.
If the computer was not configured with the optional diskette drive, 
you can install a 3.5-inch device, such as a diskette drive or hard 
drive, into the drive bay at any time.
✎
The type of bezel you need will depend on the type of device you plan 
to install. If you are installing a diskette drive, you must install a 
diskette drive bezel (PN 360189-001). If you are installing a hard 
drive, you must install a bezel blank (PN 358797-001). If you are 
installing a 3.5-inch device other than a diskette drive or hard drive, 
you must install the 3.5-inch device bezel (PN 358796-001). Contact 
an authorized HP reseller or service provider to order the appropriate 
bezel when reconfiguring the computer.
