This is normally caused by a bad battery or a bad charging circuit on the motherboard. I would suggest buying a replacement battery to solve this issue.

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:

http://pc-dl.panasonic.co.jp/dl/

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!

Panasonic CF 50 battery light flashing red light


A "Red" Flashing Battery Light on ALL
Panasonic Toughbook Models means
that the battery is no longer functional
and can no longer hold a charge properly.

If you really require a battery then you
may be able to order a replacement
battery from the Panasonic Parts Dept.

An original battery cost might exceed the
value of an old CF50 so be aware and
take note.

It is possible to completely remove the
battery pack and use the CF50 without
a functional battery pack with no problems.

Good Luck

On the Panasonic Toughbook CF29 MK1 Model,
the Battery Recalibration application is actually

a downloadable software located at this website:

http://pc-dl.panasonic.co.jp/itn/drivers/d_menu_en.html

Please remember to choose your operating system
and then find the Battery Recalibration Application.
Finally click on the "Download Now" button located
on the right hand side.

Power shuts down when diconected from outlet.bat light flashing red


Your problem is with your battery. It most likely needs to be replaced, since it wont charge. You can usually find them cheap on amazon.com or ebay.com

Toughbook will not start, we have it plugged into the wall and when we switch it on the battery light turns red and nothing else happens? Thanks, Brad M.


> battery light turns RED

For Panasonic computers, that indicates that the battery is almost completely discharged (it's YELLOW while charging, and GREEN while fully-charged).

So, my guess is that your AC adapter has failed,
and that your battery needs recharging.

Or, the socket where the AC adapter connects into your computer is damaged, such that no power from the AC adapter is reaching the computer.

Take a "MultiMeter" and check the voltage & amperage output-level from your AC charger. If "zero", go onto eBay and search on the part-number, to find a compatible replacement part.

Panasonic toughbook cf-48 two batteries went bad within a day


Place battery in freezer for 2 hours / remove and recharge, might make it last longer. (Removes any "memory" in them)

Might be worth checking the charger to ensure its working OK. Just becuase the light is on doesn't always mean its working.

The BIOS may not support the larger drive at all; I suggest you look for a Toughbook forum and repost there and check Panasonic's site for a manual download and possibly a BIOS upgrade if the unit is equipped with a flash BIOS.
