LENOVO THINKPAD X1 CARBON POWER MANAGEMENT DRIVER
A never seen error told me that the clock didn't even have battery and indeed, the next time I restarted the machine it told me the hours with 30 minutes late for like 15 seconds, until it gets the right time automatically from the network I guess. I am pretty sure this is related to this issue, but have no idea what alse to do?
I have Lenovo 2 power suppliers 90W and 65W both used to make this laptop works fine with AC attached. I have a second Lenovo X1 Carbon, exactly same model, that works perfectly with these two power suppliers.
I just noticed that if I let the AC plugged, then close the screen to provoke sleep mode not deep sleep modeand then re-open the screen, push the power-on button, Lenovo ThinkPad X1 Carbon Power Management the laptop is still plugged but now the CPU is back to 2. So at least I'll have a way to work plugged for some time, but I'd really like to fix this once for all. Power management seems to be still very bizarre -- though this seems to have actually gotten worse after installing some of the above packages because the processor tends to inexplicably throttle down to very low power levels after a burst "high" power up to 34W quickly dropping to 23W.
Eventually it'll recover, though the temperature and power shows some wild oscillations when running s-tui with stress testing. Sometimes it seems to be trying to run the CPU at 15W with a temp limit of 75C, other times it may be much higher or much lower.
What if I upgraded my old Windows installation to Windows 10 and I have previous thresholds set? If you install Windows 10 while you have set charging thresholds, they will still be in effect after the upgrade.

How can I reset charging thresholds? Then reconnect and start charging. This should reset the charging thresholds.
This is a problem with integrated batteries — for these systems disconnecting the battery using the BIOS might do the trick. I have not verified this, however.
Using some compatibility mode trickery you can make it work, but it will not be able to set the charging thresholds. Instead, you need to set them in the registry yourself.
