Panasonic Toughpad FZ-G1 tablet and Battery Pack Issue

As a result of Panasonic’s ongoing commitment to improving our products and services, we have recently identified some issues involving the Panasonic Toughpad FZ-G1 tablet in certain user scenarios, incorporating battery packs that are specified below. It is apparent in certain usage scenarios that the battery pack of the tablet could overheat and ignite, causing a fire hazard.

Using the instructions in this notice you can determine if your product is within the scope. Once you locate the model number of your FZ-G1 tablet, and the model number of your battery pack please compare them with the below list of affected products.  


FZ-G1 list of model numbers:

In combination with any of these Battery Pack model numbers:

FZ-G1Axxxxxx FZ-VZSU84U
FZ-G1Bxxxxxx FZ-VZSU97U


If your FZ–G1 tablet has one of the battery packs impacted by this safety notice, we ask you to immediately proceed with the following action:

We will provide a BIOS utility that will allow safer use of the device until an appropriate resolution is available. We are providing this utility to potentially reduce a possible overheating issue when using the FZ-G1 tablet (models: FZ-G1A, FZ-G1B, FZ-G1C, FZ-G1F, FZ-G1J, FZ-G1K, FZ-G1L, FZ-G1M, FZ-G1N) in conjunction with the FZ-VZSU84U/ FZ-VZSU97U battery pack. This utility is contained in a ZIP file. Once open and extracted, allows you to run a Batch File that changes a system setting in the tablet’s BIOS.

Please note that the BIOS Utility will reduce the capacitance of your battery to 80% and will result in a reduction battery operating capacity.

If you purchased a Panasonic FZ-G1 tablet in the European Economic Area (EEC) then please contact us immediately to receive the BIOS utility. You may contact us through one of the following options:
