When the computer does not start properly, check the following items:

Self test
While booting up the computer, self test is executed automatically and the
TOSHIBA logo is displayed on the screen.
This message remains on the screen for a few seconds.
If the self test is successful, the computer tries to load the operating system
according to how the Boot Priority Options is set within the TOSHIBA HW
Setup program.
If any of the following conditions are present, the self test has failed:
■ The computer stops and does not proceed to display information or
messages except for the TOSHIBA logo.
■ Random characters appear on the screen and the system does not
function normally.
■ The screen displays an error message.
In these instances, turn off the computer, check all cable connections and
then restart it - if the self test fails again, contact your reseller, dealer or
service provider.
