Public bug reported:
Dell XPS 9700 Laptop - BIOS latest - Ubuntu 20.04.2 (uptodate)
Logitech M720 mouse
With Bluetooth mouse acpi > "Battery 0: Discharging, 95%, 03:31:47 remaining"
Using mouse under Bluetooth, too much lag time,
plugged in USB component - much better response time.
ran acpi - now have two batteries - Battery 0 and Battery 1.
Battery 1 shows my usual display but Battery 0 showed no info.
acpi -V reported absolutely nothing about Battery 0.
Battery 0 reported info "unavailable"
Sorry but more interested in correcting problem than keeping printout so I
reverted back to Bluetooth.
Normal typical laptop display of something like "Battery 0: Discharging, 95%,
03:31:47 remaining"
Read something about acpi bug reports so I collected the following in
attachments. The kern log file ".0" after sleep - not found so I
included the kern log current file.
My guess is that acpi is picking up the battery from the usb mouse or mu
Uninterruptible Power Supply but not getting all the information.
Hope this helps.
