Title: Wrong Battery Reading after Wake from S3 Sleep since Kernel 6.8 Status in linux package in Ubuntu: Fix Released Bug description: 1. Please describe the problem: After waking up my Lenovo Thinkpad P1 Gen2 from the S3 sleep state, it shows an incorrect battery level. Sometimes the battery level forces the computer to completely shut down, including data loss, if running on battery. After a closer look at /sys/class/power_supply/BAT0/energy_now /sys/class/power_supply/BAT0/energy_full /sys/class/power_supply/BAT0/energy_full_design shows that energy_full is usually significantly higher than energy_full_design. After a reboot, the battery data is correct again until the next S3 sleep state. Sometimes it takes 2 sleep states until the battery values are read out incorrectly.

What is the Version-Release number of the kernel: Issue since Kernel 6.8.0-31 3. Did it work previously in Ubuntu? If so, what kernel version did the issue *first* appear? Before Kernel 6.8 no issues at all. I have tested Ubuntu with Kernel lower than 6.8, no Issue. Ubuntu with Kernel from 6.8 and above and the wrong battery reading started to appear. To be certain that it is the kernel I have tested with other Linux distros, like Fedora 39 and Fedora 40 which are also based on Kernel 6.8. Same issue as with Ubuntu with Kernel 6.8.0 and newer. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Reproduction is easy. Installation of Kernel 6.8.0 or newer. Putting Thinkpad P1 Gen2 to S3 Sleep and wake again from sleep. You will see wrong battery readings. Sometimes more than one sleep/wake cycle is necesarry to reproduce the issue. 5. Are you running any modules that not shipped with directly Fedora's kernel?: No 3rd party Kernel modules are used.
