support up to four IDE hard drives. When using two hard drives in the computer, one of the hard drives is installed in the dedicated hard drive bay and the other in the MultiBay.

NOTE: The dedicated hard drive bay provides limited support for the Compaq LTE Elite hard drive. See Appendix C for details.

The hard drive remains powered off from Standby (Suspend) until the first access occurs. The hard drive is powered off during Standby (Suspend).

The cooling fan is mounted in the system unit on the left side at the ventilation exhaust port. Functioning as an exhaust fan, it provides air flow across the electronic components for cooling. The fan plugs into a 2-pin connector on the system board.

The I/O connector panel is an integral part of the system board. In addition to the I/O panel, the system board supports the following:

o PC card rails and connectors

o Battery bay contacts

o Hard drive bay connector

o MultiBay mass storage device connector

o MultiBay battery contacts

o Power board connectors

o Processor board connectors

o Fan connector

o LCD panel connector

o Speaker connector

o Integrated microphone connector

o External microphone connector

o Volume control

The CPU cover, display unit, keyboard, processor board, and power board must be removed prior to removing the system board. The system board is secured with two screwlocks on the I/O connector panel, a standoff in the left rear corner, and three screws.

IMPORTANT: Correct positioning of the system board is essential for proper interconnect of the computer with either expansion base. When installing a system board, be sure the locating pins near the mounting screws properly engage the system board.
