Re: X1 Carbon 6th Gen Battery drain in sleep

No idea what you mean. My battery was losing juice fast while in sleep mode. I changed said settings in BIOS, I'm on win10, and now the report says I lost about 1% of power the last time I set my laptop to sleep which is a hell of a lot better than before.

Re: X1 Carbon 6th Gen Battery drain in sleep

Disabling the always on USB in BIOS worked. Then some update happened. Now, we're back to sleep drain.

Can you please try this?

1.  open a command prompt as administrator

2.  "powercfg /energy"

3.  wait a minute or so while the report is generated

4.  open energy-report.html

5.  are there any errors reported (highlighted in pink)?  I'm especially interested to know if you see an error like this:

 

Power Policy:USB Selective Suspend is disabled (On Battery)
The current power policy has globally disabled USB selective suspend.

You were very much right on the money. There were errors.

I take it you have an idea. That would be much appreciated.

I think USB Selective Suspend is the problem.  I suggest enabling that as the first step, then see what your battery life looks like.

 

Unfortunately, Microsoft hid the USB Selective Suspend setting on Modern Standby, but you can effectively enable it by restoring the default power plan settings.

 

1.  right-click on battery icon in the notification area (next to clock)

2.  select Power Options

3.  For your power plan, which is probably "Balanced", click on "Change plan settings"

4.  click on "Restore default settings for this plan" (near the bottom)

5.  you may have to reset any timeouts for "Turn off display" and "Put the computer to sleep" that you had set previously

6.  run "powercfg /energy" again, you should not see the errors about USB Selective Suspend anymore. 

7.  check your battery life again, is it better now?

Re: X1 Carbon 6th Gen Battery drain in sleep

I realize this is the X1C6 thread, and I have the X1Y3, but I have exactly this USB Selective Suspend error message as well.  My system has been behaving well during modern standby sleep (though I feel I may be in the minority in this, as many other X1Y3 users seem to still have sleep issues) until a few days ago.  For example, a week ago I flew to Thailand and had my laptop in my bag sleeping for 24 hours (before automatically going to hibernate after my 24 hour limit), during which it used 10% of the battery (0.4% per hour, a reasonable "well behaved" amount, I'd say).  Then the very next day I started burning through about 6% per hour in standby.  This has continued daily, despite reboots and such.  Something changed recently, and I'd love to know what!  I didn't update any drivers after arriving in Thailand, so I don't really understand what was changed.  I have Lenovo auto updates turned off, though Windows updates are on.

Re: X1 Carbon 6th Gen Battery drain in sleep

First of all, thank you for your help.

 

Second, your advice fixed part of the problem, it seems.

Maybe I should turn the always on USB settings is BIOS back to their original states as well?

Mind sharing how to pull this kind of report? It's not the same as the error report we pulled right?
