User's Manual Part 1

Cleaning or Replacing Cradle Contact Pins

The contact pins on the vehicle cradle are exposed to contamination and stress when the computer is installed and removed from the

cradle during normal daily operation. If the pins become dirty, they can be removed and cleaned as necessary using electrical contact

cleaner. Or they can be replaced. The power and ground pins are pins 3 and 8 respectively. When charging problems are encountered

and replacement pins are not available, other pins in the contact assembly can be used to field fix the unit until replacement parts are

available.

To clean or replace the cradle contact pins

1. Hold down the protective plastic cover.

2. Grasp a pin and pull straight up, being careful not to bend it.

3. Clean the pin with electrical contact cleaner and reinstall it into the cradle contact assembly.

If a pin is bent or cannot be cleaned, contact your support desk to obtain a replacement pin.

NOTE Pin 8 is not user replaceable. Contact your support desk for information about replacing this RF connector.

CAUTION Do not place any metal objects on top of the cradle that might make contact with the metal pins of the contact connector.

Doing so may cause an electrical short and subsequent damage to the cradle.

Heaters

Hard Disk Drive Heater

Your GoBook II has a hard disk drive (HDD) heater option to warm the HDD before spinning up in temperatures below 5°C,the

minimum safe operating temperature of the HDD. The heater is built into the removable HDD module and operates as needed when

the computer is turned on or is in an operational state. If the temperature is below 5°C when booting or resuming you will see the

message "Warming internal hard drive. Please wait...". The unit will continue booting when it detects the HDD is warm enough to

operate safely.

NOTE If you are using the computer in a cold temperature environment and the battery level is too low for the heater to operate, you

will see the error message "Battery too low to warm the hard drive. Shutting down..." and the computer will shut down. Apply

external power and reboot.

LCD Heater

The GoBook II also has an optional CCFL heater to improve display brightness in a cold environment. The heater consists of a film

and heater strip that is bonded over the CCFL area of the display. It is designed to turn on when the temperature is cold enough to

impact display brightness.
