l The computer is warming up before start up. Wait for the com-
puter to start up (takes up to 30 minutes). If, "Cannot warm up the
system" is displayed, the computer failed to warm up and does
not start. In this case, turn off the computer, leave it in an environ-

disable the screen saver.
l If the power switch is pressed immediately after the battery pack
has been mounted on the computer, and while the AC adaptor is
not connected, it may take about five seconds before the power
indicator lights up and the computer turns on. This is because
the computer is checking the remaining battery charge; it is not a
malfunction.
