Using Your Fujitsu Laptop PC Safely:
Request for Customers to Update the Battery Charging Control Function
(Fujitsu begins distribution of the update via Windows Update)
Thank you for your continued commitment to Fujitsu and its products.
Fujitsu has released an update for the Battery Charging Control function used on its laptop PCs in order to enable customers to use them more safely.
We would like to ask you to apply this update to your laptop PC.
Fujitsu is distributing this update automatically via Microsoft's Windows Update service. If the following screen appears, the update applies to your laptop PC so please follow the instructions to apply the update.
*The software to be updated will vary depending on the model of your laptop PC.
This update is intended to make the used standard battery technology even safer. The update minimizes the internal pressure according to the battery drainage by controlling the charging of the battery, thereby allowing our customers to use their Fujitsu laptop PCs even more safely. To ensure that your laptop PC is protected against this battery drain problem, please be sure to apply this update.
Please note that other models have been added to the range of applicable models since October 30, 2018. If you have already applied the update for the Battery Charging Control function, you do not need to confirm the applicability of your laptop PC again.
The battery used for a laptop PC is a consumable component and it will gradually drain even if you use your laptop PC with the AC adapter plugged in. If you feel that your battery may have drained, please also consider purchasing a replacement battery pack to ensure that you can continue using your laptop PC safely. For a description of how to recognize and confirm signs of battery drain, see the "Guide to Checking for Battery Drain."
Necessary software: "Fujitsu FUJ02E3 Device Driver", "Fujitsu System Extension Utility", "Fujitsu BIOS Driver","Fujitsu FUJ0420 Driver" and "Intel MEI® Driver"
There is a New BIOS Update Tool for the LIFEBOOK A530 models. If you applied a BIOS update before April 19, 2019, you will need to apply the new BIOS update ASAP. Please follow the instructions displayed on the Figure 1 pop-up message above.
With the previous BIOS (V1.21) released on February 13, 2019, the CPU fan may not operate properly, which can lead to heat build-up if the power supply is stopped or the battery level becomes zero. Please apply the latest BIOS update ASAP by“FUJITSU Battery Ctrl Update Tool” to avoid the above scenario.

Batteries of notebook PC’s are consumables and they drain gradually even if you use your PC with an AC adapter.
