Connect the AC adaptor.
Insert a fully charged battery.
Remove the battery pack and the AC adaptor, then connect them again.
Even if the AC adaptor and battery pack are correctly connected, if the battery indi-
cator is not lit, the AC adaptor protection function may be operating. Disconnect the
AC cord, wait three minutes or more, and reconnect the AC cord.
If a device is connected to the USB port, disconnect the device, or set [USB Port] or
[Legacy USB Support] to [Disabled] in the [Advanced] menu of the Setup Utility.
If a device is connected to the ExpressCard slot, disconnect the device, or set
[ExpressCard Slot] to [Disabled] in the [Advanced] menu of the Setup Utility.
The computer is warming up before start up. Wait for the computer 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 envi-
ronment of 5 °C or higher temperature for about an hour, and then turn on the power
once more.
Leave it in an environment of 5 °C or higher temperature for about an hour, then turn
on the power once more.
Turn off the computer and remove the RAM module, then confirm whether the RAM
module has conformed to specification. When the RAM module has conformed to
specification, install it again.
Press and hold the power switch for four seconds or longer to shut down the com-
puter forcibly. (Data not saved will be lost.) Then disable the screen saver.
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 malfunc-
tion.
