> I always wondered, what is the use case for hibernate. You have to dump the entire RAM on your SSD, and then read it back on resume. Incredibly wasteful and slow, if your RAM is 16GB+. > Suspend is something else; but I haven't seen it fail in years. Thinking about it, the last time I've seen it fail, it was a Mac. > Anyway, both suspend and hibernate is what the firmware is responsible for; the host OS just calls the firmware and it does the job. So contact your system vendor if it doesn't work for you. i rely on hibernate since my battery is dead and non-replaceable. effectively, hibernate has added several years of life to my laptop. i have found that in linux, hibernate and suspend take a round robin approach in the first few years of a device. now, suspend works and hibernate doesn't. next, hibernate works and suspend doesn't. sometimes there is back-and-forth. and then they both work. definitely seems to require coordination between os and firmware.
