Troubleshooting (Basic)
Follow the instructions below when a problem has occurred. There is also an advanced troubleshooting guide in the
“Reference Manual”. For a software problem, refer to the software’s instruction manual. If the problem persists, contact
Panasonic Technical Support. You can also check the computer’s status in the PC Information Viewer (
è
Refer-
ence Manual
“Checking the Computer’s Usage Status”).
n
Starting Up
Cannot start up.
The power indicator or bat-
tery indicator is not lit.
l
Connect the AC adaptor.
l
Insert a fully charged battery.
l
Remove the battery pack and the AC adaptor, then connect them again.
l
Even if the AC adaptor and battery pack are correctly connected, if the battery indicator
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.
l
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.
l
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.
l
Press
Fn

F8
to turn off the concealed mode.
l
Check the [UEFI Boot] setting of the Setup Utility. [UEFI Boot] should be set to
[Enabled] /
[Disabled].
The power is turned on but
“Warming up the system (up
to 30 minutes)” appears.
l
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 environ-
ment of 5
°C
or higher temperature for about an hour, and then turn on the power once
more.
After adding or changing
the RAM module, the power
is turned on but nothing is
displayed on the screen.
l
Turn off the computer and remove the RAM module, then confirm whether the RAM
module has compliant to specification. When the RAM module has conformed to specifi
-
cation, install it again.
The computer does not
enter sleep mode while the
screensaver is running. (The
screen stays black.)
l
Press and hold the power switch for 4 seconds or longer to shut down the computer
forcibly. (Data not saved will be lost.) Then disable the screensaver.
It takes time for the power
indicator to light up.
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.
