Hard Disk Drive Heater
If your GoBook III 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 III also has an 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.
