Description

Issue

If you have Dell Inspiron 7xxx or other similar laptop and face battery detection issues, using this kernel instead of default one might help. The main symptom is battery slot being present, but battery being absent:

[root@dell9 ~]# dmesg | grep batt
[ 1.248629] ACPI: Battery Slot [BAT0] (battery absent)

About this repo

This is Fedora LInux Kernel for use with Dell laptops. It has the following configuration flag: CONFIG_ACPI_REV_OVERRIDE_POSSIBLE=y

References

• Battery absent with kernel 4.6
• Battery not detected at boot on Dell Inspiron Series 7000 model 7437 with v4.2
• Battery not working since Fedora 24 on Dell Inspiron 7537
• No battery after boot. Dell 7537
• 15.10 - no battery detected in Dell Inspiron 7000 series laptops

• 16.04 - Battery not detected until plugged in via AC

Installation Instructions

Enable this repo by typing

sudo dnf copr enable gronki/kernel-dell

Exclude the default kernel from the repositories, edit the .repo files

gedit admin:///etc/yum.repos.d/fedora{,-updates}.repo

Append following at the end of each of three sections in both files:

exclude=kernel* perf python-perf

Note that the above change will crash PackageKit while trying to fetch updates in Fedora 24. After moving to 25, everything works for me.

You need to add following boot parameters to GRUB_CMDLINE_LINUX in /etc/default/grub:

acpi_rev_override acpi_osi=Linux

After installing new kernel and rebooting, run:

dmesg | grep ACPI | grep REV

and check if it says

[ 0.000055] ACPI: Overriding _REV return value to 5

The battery indicator should be working again.
