Can anyone help me with a suspend-resume problem?
I have two identical ThinkPad laptops (7764CTO). One works fine. The other will not "hibernate" (suspend-to-disk) and "thaw" (restart after suspend-to-disk). The alternative "sleep" (suspend-to-ram) and "resume" (restart after suspend-to-ram) works fine.
I don't find any log contents (that make sense to me) to tell me:
- Did suspend-to-disk reach successful completion? If not, what went wrong?
- Did start-up successfully detect the need to restart-from-hibernate? If successful suspend, why did detection fail?
- Did restart-from-hibernate fail its processing? What was going on at the time of failure?
I found postings about suspect modules and problem devices (where suspend-to-XXX matters) and made some progress, but the fact that one laptop works while one fails is driving me crazy.
