How to select a boot device

The Panasonic Toughbook CF51 may not be able to boot
from a USB external Hard Drive. When you press the F2
function key and go to BOOT devices, I believe that USB HDD
is NOT an option. However, when the drive is plugged-in
and you start the CF51, press the ESC key immediately.
All boot devices should be shown and you might be able
to boot from that menu. If not, then it is NOT bootable.
Good Luck!

the procedure to turn "on" the wireless lan:

Laptop dies when unplugged

Panasonic Toughbook PC Laptops usually have
very reliable battery pack. When your unit is plugged-in
but the Power is OFF, you should see an LED light as follows:
RED FLASHING: Means the battery needs replacement.
Orange/Yellow Solid: Means battery is charging.
Solid Green: Means battery is fully charged.
NO Light AT ALL: Means that Battery Pack is missing.

There is also a battery calibration utility on all Panasonic
Toughbook PC's manufactured since 2004. This is a factory
installed software and is only present in factory units.

This software may also be downloaded as a driver from the
Panasonic Toughbook website as follows:

Check also in the bottom right hand corner under
Windows for the battery Icon. This will indicate if
the battery is charging, present or not present,
and under Windows 7+ will indicate if the battery
needs to be replaced or not.

Good Luck!

When pressing the power button the blue LED on the front for power, hard drive illuminate briefly and then go out. The LED about the mouse pad does the same as does the DVD drive. Does this sound like...

  1. Check your power cord & adapter.
  2. If its working then check the battery, reseat the battery & check.
  3. If available then check with another battery.
    If no, then remove the battery & switch on the PC in AC mode.
  4. Check if battery charging indication or AC power on indication is glowing. if not then need to change ur motherboard.
  5. If indication is OK, but could not power ON then check ur RAM for any loose connection or dust. clean & reinstall.
  6. If still no display, connect an external monitor, check if display is coming. If Display is coming then your LCD need to replace.
  7. Still nothing change, take it to a service centre.

Panasonic Toughbook CF-51 shutting down

Sue, it's not the inverter board. People who don't really know much about laptops will often diagnose them incorrectly, especially computer repair shops. The problem you're experiencing is most likely related to your motherboard. Unfortunately the most expensive part to replace on most laptops.

Your best bet is to probably just have any important files from the laptop extracted by a repair shop and then selling the computer "As-IS" on ebay. Or you could try another local repair shop to take a look at it. I wouldn't pay any money for a diagnostics since it would take most techs about 5-10 minutes to confirm what I just typed.
