Re: X1C6 BIOS 1.34 update halved my battery time (and I think it's related to the CPU microcode)

My remaining battery time jumped way up after applying this fix!

 

However I'm getting the following errors in my report, even after restoring default power plan settings

 

CPU Utilization: Processor utilization is high
The average processor utilization during the trace was high. The system will consume less power when the average processor utilization is very low. Review processor utilization for individual processes to determine which applications and services contribute the most to total processor utilization.
Average Utilization (%) 12.31

Platform Power Management Capabilities: PCI Express Active-State Power Management (ASPM) Disabled
PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.

@someotherguy - the global usb selective suspend was the issue. Now back to 13+ hrs of battery left. For some reason there are a few devices that still are not entering selective device.

Nevertheless, thanks again - you're a god amongst men!

What!? 13+ hours? I've been lucky to get 7 hours. I have the WQHD "HDR" display, but the difference cannot be that great, can it?

Apparently, it can. On the other hand, maybe you opted for the UHD HDR display for a reason and are using some pretty heavy software like Photoshop or Blender?

 

Mine is spending less than 10% an hour, so I've marked the thread as solved.

 

And to think I blamed everything on the BIOS update! )))

Mostly Premier, but on off days, its still topping out around 7 hours, usually less.

 

Amusingly, I've found the gamut/accuracy of my laptop monitor doesn't matter, since I reference against a desktop monitor, anyways.

 

Oh, well. Facts known in posterity, I guess Smiley Very Happy Glad to see better battery life is possible!

Yep! Another couple of Intel CPU generations, some battery technology improvement, and maybe Firefox or Chrome devs actually doing something about their behemoths' energy consumption - and soon, perhaps in 3 to 5 years, we may see a laptop that lasts from dawn till dusk.

 

Or not. Smiley LOL

Re: X1C6 BIOS 1.34 update halved my battery time (and I think it's related to the CPU microcode)

Is there a fix for Linux users?

 

I'm running Ubuntu 18.04. The laptop-mode-tools configuration file

 

/etc/laptop-mode/conf.d/runtime-pm.conf 

 

is showing that I have the autosuspend mode enabled:

 

CONTROL_RUNTIME_AUTOSUSPEND=1,

 

But still, my battery life seems much shorter than before.

 

Any insight is much appreciated!

I have exactly the same message as this. What should I do?

The first message about CPU utilization means that you have some background tasks running.  This is not unusual, and you can look down lower in the report to find out which task(s) are consuming CPU resources, and close them before running the energy report again.

 

The second message refers to a bug in Intel's Thunderbolt implementation.  To avoid this bug, ThinkPad BIOS disables the APSM at OS level and handles it at BIOS level instead.  It makes this message appear in the energy report, but my understanding is that there is no actual impact to energy consumption.

@someotherguy, thank you for the quick fix. It restored my original battery life.

 

Just wanted to let you all know that Lenovo has released a critical update for this through Lenovo Vantage.
