Re: X1 Carbon 6th Gen Battery drain in sleep

Guys, and why not to use Linux standby mode in BIOS, for me this s3 state works great with 3 hours before going to hibernate option.

To do a complete shutdown, hold down the Shift key while clicking on Shut down.

I don't work for Lenovo. I'm a crazy volunteer!

Re: X1 Carbon 6th Gen Battery drain in sleep

Upgraded to Ubuntu 19.10 the day before yesterday and later noticed that my laptop didn't freeze up after I had the lid closed, so I decided to do an experiment: instead of shutting it down after work, I shut the lid to suspend it. Opened it two hours later. Perfect system restore, no noticeable battery drain, no frozen screen, no fans running hot. Will experiment more, but looks promising so far.

Re: X1 Carbon 6th Gen Battery drain in sleep

Follow-up for those interested: I left it in suspended state overnight, around 13 hours. Again, perfect system restore. But there was a battery drain as it had gone from 99% to 84% during that period, so a battery drain of slightly more than 1%/hour.
This is after upgrading to Ubuntu 19.10. I'm also on the latest BIOS, with Linux Standby Mode and Wake on USB disabled. Not sure if that last setting matters at all, but I'm not going to experiment with it.
Not Mac-level battery preservation for sure, but very useable. A colleague who was also on Ubuntu 19.04, had problems with screen, wifi etc. (on a different Lenovo model), and all those problems went away after he upgraded to 19.10, so at this point there is probably not much more for Lenovo to do about it.

And we're back...
