Hello, you can try lsmod to see which modules actually get loaded (possibly even before and after successful suspend - just in case there is a difference). On the other hand you could check the kernel versions of the working kernel and the new one and try to downgrade your kernel if necessary: my t510 doesn't wake up from suspend to ram (I never tried hiberation) since at least 4.1.3 (possibly 4.1.y) right now either - without any config changes. I had to time to bisect/investigate, but it worked fine with 4.0.y. WKR Hinnerk
