    At work we have many Panasonic Toughbook CF-18's. Celeron processor, pretty up to date model, just purchased 3 years ago. This is the second one that has had this problem. You come to work, put it on the docking station, slide the turn on button and green light comes on, wireless comes on but no other life is detected. Screen is black, HD does not spin. You take it off docking station and try battery power get same thing. Try AC power and no change. Gonna try swaping the HD with another CF-18's but I'm not optomistic. Any suggestions would be helpful.

Looks like this is a Toughbook shell problem. The hard drive worked in another CF-18. I beleive this is an internal power problem. I hope it's under warranty : }

Sounds like a capacitor issue with the boards secondary supply side to me, recommend you dis assymble and check capacitors with low esr meter to determine which way to start trouble shooting power delivery issue. Obviously your getting power to the plug but have you LOAD tested the power supply? Try another one to see?

    Cf-29 no operating system

    You will require the internal Panasonic Toughbook CF29 optical drive (DVD). The cost of such a drive (used) in should be $50 or less.

    You will also require a Windows 7 DVD.

    You may be able to download an ISO file and burn your own.

    Try this Microsoft Website:

    You must use the 32-bit version, NOT the 64-bit version.

    Please remember to set the DVD as the first boot device in the BIOS of the CF29.

    That is it. Good Luck and Best Regards from:

    Where is the serial number on a cf19

    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!

    Screen stays dark

    On ALL Panasonic Toughbook Models,
    if the screen stays dark I would shut-off the
    Toughbook and connect an external monitor
    to the VGA port (15-pin female connector),
    which is usually BLUE in color.

    Make sure the monitor is ON first, then
    turn ON the Toughbook.

    If the monitor comes on then your problem
    is the backlight or possibly the inverter of the

    If no image is shown on the external monitor
    and the screen stays dark and you cannot
    hear any startup (ie. Windows) sound, then
    your video card may be defective. Very few
    Toughbooks fail this way since they are
    normally very very relaible but it can happen.

    Have you tried hooking up an external monitor? If you hook it up and see video on that it's a screen issue. If you hook it up and it does the same white thing it's bad video on the motherboard.

    Mouse cursor jumping uncontrollably all over screen.

    Your touch pad drivers need to be installed. Power off the laptop. Install an external mouse, power back on and install drivers. When finished, power down, remove the external mouse and reboot.
