Hood Sensor
If the access panel is removed while there is still power to the computer, the hood sensor will cause
the system to stop and display the Error 912 message after system reboot and will beep 5 times for 5
seconds. If the alarm sounds, close the access panel, tighten the thumbscrew, then reboot the
system. The system will enter the operating system successfully. If the error message persists, press
the
F10
key immediately when the HP Logo screen is displayed to enter the Computer Setup menu.
