The fuck it does.

I have a lenovo t14 something or other. I have to fiddle with the bios to get suspend work. This means that the battery lasts about 4 days.

However whenever it resumes, the touchpad appears to only work at 5 frames per second.

Moreover, its impossible to hibernate with secure boot.

Intel or AMD? Intel removed S3 support from the platform entirely, and S0ix support was spotty until recent kernels/distros. Lenovo royally screwed up the AMD firmware, so kernel 5.18 includes a hack to force-suspend the NVMe subsystem regardless of what their broken ACPI handler wants to do.

Hibernation with secure boot is actually disabled because of "kernel lockdown", which most distros leave enabled. I feel like the security people push these patches through and dismiss user needs by waving the "hibernation is impossible to secure and standby is good enough" flag, and we have to live with a broken feature set compared to Windows. It's not a great attitude to have, from the user standpoint anyway.
