disturbed from the original settings. If the settings appear to have
altered, there may be a fault with the CMOS battery. See Appendix

Sensonic Anti-theft device
If the Sensonic Anti-theft siren sounds and you need to disarm it
you can do so depending on the current state of the computer.
The computer is off
If the computer is off when the siren sounds you need to turn on
the computer and you will then be prompted to enter the password.
This will stop the siren.
The computer is in standby
If the computer is in standby state when the siren sounds, press the
purple standby button on the front bezel to bring it out of standby.
You will be prompted to enter the password to stop the siren.

Floppy disk drive
If you have problems accessing a diskette or floppy disk, check that
it is inserted correctly, that it has been correctly formatted, that it is
not write-protected, and that the permissions assigned by the BIOS
allow the intended access. Some application software also may not
allow you to read or write to floppy disks during certain other
operations, or until you are about to exit the programme.
