Thinkpad [2] : Power malfunction on suspend; faster suspend to disk?

Another thinkpad issue, this one more serious: when I suspend to ram, my Thinkpad T440s sometimes has a serious power malfunction. While suspend generally succeeds, at some point the pulsing power light on the lid goes out and it’s no longer possible to power on the laptop. I have to open the lid, disconnect the internal bettery, and generally also hit the internal power reset button. I can then restart, but of course lose all my work. At first this happened about once a month, then once a week, and now it happens several times a day. 1. Anyone else having this issue? And do you know what actually causes it, and if it can be fixed? I’ve searched online and there are various threads about it, but I haven’t found any actionable information. Recently updated my BIOS and changed some BIOS settings, but to no apparent effect. 2. As a workarond, I’ve just switched from suspend-to-ram to hybrid suspend, which writes an image to disk before suspending to ram. (Took me a long time to do this, because I had no swap partition & my main partition was encrypted, so I had to resize the encrypted partition, ettc.) This seems to work! Yay! However, suspend-to-disk is really slow. In the old days I used Txonice for hibernaion, but that project has really slowed down in the last few years. Is anyone still using it? How about uswsusp? Is either one compatible with the systemd hibernation commands? My experience with tuxonice was that it was abot 5 times faster than native hibernation, so I’d really like to compress the disk image Thanks again! Matt
