The number 3 key came off my Panasonic toughbook, how do i put it back on

On ALL Panasonic Toughbooks you can
boot into safe mode as follows:

Make sure the Toughbook is OFF.

Power on the Toughbook and immediately
start to press repeatedly the "F8" function key
which is usually located above the number 7 key.

You only have 2-3 seconds to do this and this
will only work in Windows XP, Vista or Windows 7.

A "text-only" screen will come up. You can then
choose SAFE MODE or if you also need to
connect to the internet choose:
Safe Mode with Networking.

Use the UP or Down Arrows to highlight the
selected option and then press Enter.

That is it.

Good Luck!

The serial number on ALL Panasonic Toughbooks
built since 2004 are located in one of two spots:

1) On a small white sticker or label on the underside
of the Toughbook. The serial number starts with a
number followed by a letter.

2) When you press the "F2" Function key immediately
upon startup you will enter the BIOS. On the first page
of the BIOS you will find the Serial Number. Again it
starts with a number then a letter.

That's It!
Good Luck!

For ALL Panasonic Toughbook Models
and for all Operating Systems
(Win XP, Vista and Win'7):

To start in safe mode, press the "F8" function key
(located ABOVE the number 7) immediately and
repeatedly as soon as you power-ON your
Panasonic Toughbook model.

You will see three choices in a text-only Windows:

Safe Mode (without networking)
Safe Mode with networking (my regular choice)
Safe Mode with Command Prompt

Use the UP or Down Arrow Keys to HighLight
the selction and then press Enter to choose.

That is it!
Good Luck,

If you choose to install Windows XP on the Panasonic CF52,
then please either order the original recovers DVD directly
from Panasonic, or if you wish to re-install from scratch yourself,
please use Windows XP SP3 (service pack 3) and NOT SP2.

You will find the drivers here:

Official Support Download Center of the Drivers Manuals and FAQs TOUGHBOOK...

You can even re-install with this XP SP3 CD:

Just make sure to use your Windows XP COA license located
on the back of the Panasonic Toughbook which looks like this below

Good Luck to you and Regards from:

On any Panasonic Toughbook, I would try to hold down the power button for 12-15 seconds continously unit you hear an audible beep and that will cause the unit to "reset". Then you should be able to power back on as normal. If this does not work, try unplugging the Toughbook, taking out the battery pack. Do not yet put the battery back in but plug it back in. Then try to start the unit. If this does not still work, then try holding down the power button again for 12-15 seconds. If the unit is just stuck in suspend or hibernate then one of these actions is almost certain to work.

Good Luck.

Press the NumLk/ScrLk button at the top right corner. That will turn off the 9-key number and symbol buttons. The Function key dosn't get stuck, just the number lock key.
