System BIOS and Setup
7/12 FT1200 OWNER’S HANDBOOK
Repeating short beeps
. Usually indicative of a keyboard key stuck
down, but may be due to the keyboard interface failing.
One long and one short beep
. POST has detected an error on the
video adapter in the system. There may be no display on the screen.
One long and two short beeps
. This means that either the video
system is faulty, or that a video I/O adapter ROM is not readable.
Two long and two short beeps
. The video subsystem cannot be
supported by the main system POST. This can occur when the
video subsystem is replaced or changed on site.
Many of these following codes indicate a serious fault and the
system may halt. Switch off for 20 to 30 seconds and try again. If
the fault persists, make a note of it and call your maintenance
provider.
