Creating a Utility Partition
When you install a new hard drive, always create a Utility partition on the drive before loading any
software.
 1. Insert the Recovery CD in the CD-ROM drive. To open the drive when the computer is turned off,
insert a straightened paper clip into the hole on the front of the drive.
 2. Restart the computer. If the computer is running, click Start, Shut Down, Restart.
 3. When you see the HP logo, press ESC.
 4. Select the CD or DVD drive as the boot device.

 If you want to create the Utility partition without installing the factory software, click Advanced
and select the option to not install the operating system.
 If your hard disk is partitioned into several drives, you can install the factory software on drive C
without affecting other drives. Click Advanced and select to restore only the C partition.

Reassembly Notes
 · Tighten screws around the CPU as denoted on the heatsink assembly.
 · When installing a new heatsink, use the thin heatsink when the bottom case has a circular vent. Use
the thick heatsink with all other bottom cases.
 · If the power supply PCA has a metal cover on it, ensure that there is not a spacer pad in the same
location on the heatsink. If both are present, remove the spacer pad.
  Caution
 
Restore proper thermal contact when installing the heatsink. Otherwise, performance can be
significantly degraded.
 
Carefully clean the heatsink and CPU surfaces and install a new thermal pad on the heatsink in
these situations:
  · Required whenever you install a new CPU for any model.
  · Required whenever you remove the heatsink from an Omnibook 6000 with an 800-MHz or
faster CPU.
  · Recommended whenever you remove the heatsink from any other model.
