For me it was not needed to change the parameter '\_SB_.BAT1._STA'

Title:
  battery not detected by ACPI

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On my freshly installed Fujitsu Lifebook A3510 now running kubuntu 21.10 with 
kernel 5.13.0-22-generic, there is an issue with the internal battery. When 
kernel boots up, ACPI isn't able to detect it correctly, see dmesg line:
  [    0.528105] ACPI: battery: Slot [BAT1] (battery absent)

  But asking lshw for power devices, it says:
  *-battery                 
         description: Lithium Ion Battery
         product: CP753347-01
         vendor: FUJITSU
         physical id: 1
         serial: 02A-Z201219003557Z
         slot: Internal Battery
         capacity: 45032mWh
         configuration: voltage=10,8V

  I've updated the BIOS to latest version 1.12 already, with no better result. 
What is the problem here, and how can I fix it?
