Installing a New Battery

When your workstation no longer automatically displays the correct date and
time, it may mean the battery providing power to the real-time clock needs to
be replaced. Battery life is usually about five years. Prior to installing the
replacement battery, read the following section.

Running Computer Setup

Computer Setup automatically detects and configures most Compaq
components, including Compaq hard drives. If your workstation has a
Compaq hard drive you do not need to run Computer Setup prior to installing
the replacement battery. However, if your workstation has a third-party hard
drive, you MUST complete the following steps before installing the
replacement battery:
1. Run Computer Setup and record the drive type displayed in the System
Configuration Summary.
2. If the drive type number is 65 or 66, record the drive parameters.
Drives with these designators are user-defined types, also called soft-
drive types. Whenever the nonvolatile memory (CMOS) has become
invalid, such as after the installation of a new battery, drive parameters
must be entered manually for these user-defined drives.
After you have completed the battery installation, run Computer Setup and use
the drive table parameters recorded earlier to reconfigure the system.
NOTE: Drive parameters must be reentered after battery installation in order to
reconfigure the hard drive. The hard drive is inoperable until this is done.
