Resetting the Omnibook
Occasionally, Windows or the computer may stop responding, so that you cannot turn the computer off. If this happens, try the following in the order listed:
•If possible, shut down Windows: press CTRL+ALT+DEL, then click Shut Down. Press the blue sleep button to restart.
•Slide and hold the power button for four seconds, until the display shuts down, then press the blue sleep button to restart.
•Use a straightened paper clip to press the system-off switch on the left side of the computer. Press the blue sleep button to restart.
•Undock the computer if docked, unplug the AC adapter, remove the main battery, then insert a straightened paper clip into the computer’s system-off switch. Press the blue sleep button to restart.
Figure 1-6. Resetting the Computer
Resetting an Expansion Base
To reset an expansion base—and the computer, if docked (see the following page)—insert a straightened paper clip into the reset hole on the bottom of the expansion base. You can also reset the expansion base by undocking the computer and removing all AC and battery power from the base.
Note
To boot from a CD-ROM or DVD drive in the expansion base, insert a bootable CD (such as the Recovery CD) into the drive, then restart the computer. Press ESC when the HP logo appears during reboot, then select the CD-ROM/DVD drive as the temporary boot device.

Docking and Undocking the Computer
You can dock or undock the computer in any power state: on, off, Standby mode, or Hibernate mode. Make sure, however, that the computer is not entering or resuming from Standby or Hibernate mode when you dock or undock, or the computer could lock up.
Docking the Computer
By default, the computer automatically turns on when you dock it. If you have trouble inserting the computer or the docking latches stick, use the emergency undock latch.
1.Optional: plug the AC adapter into the expansion base.
2.Insert the back of the computer into the expansion base, then lower the front end into the base and press down firmly until it clicks into place.

Undocking the Computer
1.Press the undock switch. (You can use the undock switch when the computer is on, off, or in Standby or Hibernate mode.)
–or–
Click Start, Eject PC.
Figure 1-8. Undocking the Computer
You may need to wait 10 seconds or more for the computer to undock—the computer may not respond while it is updating its configuration.
2.If the computer will not undock using the undock switch or Start menu, use the emergency undock latch: slide the button down, then move the entire latch forward.

Connecting a Floppy Disk Drive
When needed, you can connect the floppy disk drive to one of the computer’s USB ports.
•Connect the USB floppy drive cable directly to the floppy drive and to the USB port.
You cannot use the USB floppy cable to connect to any other type of drive module, such as a CD-ROM or DVD drive. The USB cable is for floppy drives only.

Internal Design
The motherboard PCA is the central component of the computer’s design, and plays a role in virtually all system functions. Most components connect directly to the motherboard.
The following figure shows the connections among the replaceable components in the computer and expansion base. In addition, Table 1-9 on page 1-20 lists the roles that these components play in the functional subsystems of the computer and expansion base.

Caution
Always provide proper grounding when performing repairs. Without proper grounding, an electrostatic discharge can damage the computer or expansion base and their components.
Notes
Reassembly steps are the reverse of the removal/disassembly steps. Reassembly notes are included at the end of each removal procedure.
Symbols like this throughout this chapter show approximate full-size screw outlines. You can use these to verify the sizes of screws before you install them. Installing a wrong-size screw can damage the unit. (The symbol at the left represents an M2.5×5mm T-head screw.)
