## Update 2024-08-14
Two important things to add:
1. After a recent system update, **suspend (sleep) stopped working**. First I
suspected the NVIDIA driver to be responsible, it had been upgrade to version
560. However, when I downgraded the driver, the problem persisted. Finally I
found a [thread][] on the Fedora Discussion forum which suggested to disable
ethernet in BIOS. Tada! That was it. Hopefully, with a future kernel or
firmware upgrade, I will be able to use ethernet again, as I prefer to have
cable-bound internet at home. The current linux kernel is 6.10, upgraded from
6.9 just recently.
2. Here's another [interesting report][techtipsy] from someone running **Linux on a P14S**,
albeit Gen 4 (mine is Gen 5) and with AMD and integrated graphics (I have
Intel with dedicated NVIDIA GPU). The author (Herman) also notes the battery
drain (even with AMD and iGPU) and the build quality which is somewhat below
the T series. Herman has also posted about [controlling fan speed with a simple
script][fancontrol], and I think I am going to tinker with it in the future,
because the following works on my P14s Gen 5 with Intel CPU and NVIDIA GPU:
```bash
# This is just a proof of concept, spin up the fan and spin it down again
# Run as root
echo level 7 > /proc/acpi/ibm/fan; sleep 5; echo level 1 > /proc/acpi/ibm/fan
```
