Please share the journal contents when this problem occurs.

Have you install the intel-ucode package and configured your boot manager to load it?

This seems to be a known problem but the Lenovo site only provides a workaround for Windows: https://support.lenovo.com/gb/en/soluti … s-thinkpad

We could probably do something similar in Arch by applying the cpufreq.default_governor=performance kernel parameter via the boot manager or by writing to sysfs but it will probably kill your battery life. GNOME has a similar "performance" slider that could also be used.
