Confirming this issue on a Lenovo ThinkPad P50 (20ENCTO1WW). System details: Ubuntu 24.04.4 LTS Kernel: 6.8.0-106-generic (6.8.0-106.106) CPU: Intel Core i7-6700HQ (Skylake) GPU: Intel i915 (Skylake) + NVIDIA Quadro M2000M (GM107) BIOS: N1EETA2W (1.75)
Symptoms: System enters S3 deep suspend successfully (power light flashes green), but never resumes. No input wakes the machine — requires a force power off. No resume entries appear in the journal; the last log line is "PM: suspend entry (deep)". Kernel 5.15.0-125-generic suspends and resumes without issue on the same hardware. Fix: Disabling the Security Chip (TPM) in BIOS under Security > Security Chip resolved the issue. Suspend and resume now work correctly on kernel 6.8.0-106-generic.
