Laptop won't "hibernate" then "thaw"

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.

Completely stumped.

How big is your SWAP? For default hybernation you need at least 2xRAM of swapspace. You can configure your kernel to use a file-swap instead, but this is not standard and a bit harder to install
