Re: PSA: Better battery life for X1 Extreme / P1

Same. Quite frustrating to have settings at levels that should get something in the 8-9 range. I have some recollection of Lenovo advertising 15 hour battery life. Not sure what universe that would be in.

MobileMark 14. In that testing program, they can reach 15 hours. Is it representative of real world use? MobileMark's makers believe so. I know to divide that number in half, to get the real world usable time (especially if I want the battery to be usable after a few months - full charge/depletion cycles are not friendly to any deployed Li-ion battery composition).

 

Is it deceitful advertising? I do not know the answer to that.

Question is whether after some breaking in, the battery will start showing more than 4 hours usage available even at full charge.

Can someone from Lenovo reply?

Has someone got any response from Lenovo regarding battery life problem on X1 Extreme?

 

This really helps:

Go to device manager, select dedicated nvidia GPU -> disable it 
then -> reenable

 

Thanks

Markus

Thanks Eason85. 

 

I got my X1E non-4k version 2 weeks ago. Got the same battery problem. Battery lasts +/- 3 hrs always. I had been only run Google Chrome and sometimes MS Office Excel so far. 

 

I have tried a couple of times to "Go to device manager, select dedicated nvidia GPU -> disable it 
then -> reenable" and looks like this method did not work for me. e.g. I am running on battery with 50% battery life, 50% screen brightness, running only Google Chrome on which I am writing this post. Both the Lenovo Vantage and Windows 10 battery indicators show me there is 1 hr 45 min left. 

 

Any body else has the same situation as mine?

I'm amazed some are reporting they are getting 6 or more hours.  I"m only getting about 3.5 hours battery life running only a web browser and excel.  Considerably less if I start loading videos or anything.

Is it possible there are a bad batch of batteries used in some X1E and P1 laptops? I know when I am on AC power that my battery percentage charge decreases about 1% every few days. That discharge without any battery use seems odd, possibly indicative of a defective battery.

Same situtation here. I bought Thinkpad P1 i78750H/P1000/FHD few days ago. When unplugging from AC, battery indicator shows only 2h30min and the battery drain is huge. I disabled and than reenabled nVidia card and after few minutes it shows 7h54min!

 

Lenovo Team, please fix this. That shouldn't be an issue in premium class laptop.

 

EDIT:

Moreover the temperatures dropped by 10 degrees Celsius, so the bottom of the notebook is not burning my legs now.

The issue is still here and I'm too lazy to disable and reenable graphic card every reboot, so I thought "Is it possible to do it automaticaly?".

Turns out it is :) 

 

I downloaded program called DevManView from https://www.nirsoft.net/utils/device_manager_view.html

You can operate by command line to do multiple things with Your devices, including enabling and disabling them. So next thing You can do is write little script in notepad and save it as executable .bat file.

You put that file in the same folder as DevManView.exe, and make a shorcut on desktop to reboot Your graphic card. Until Lenovo fix this issue, use this method :)

 

If You want to go full automatic add .bat file to Task Schedule and program it to execute everytime You turn on computer.

 

To obtain Graphic Card ID  You can go to properties in Device Menager or copy it form DevManView.

I get the idea from Youtube, link: Enable and Disable Device from Shortcut on Desktop, You can watch for step by step instructions.

 

It should be like this (Timeout delays enabling card for 5 seconds):

 

DevManView.exe /disable "<YOUR GRAPHIC CARD ID"
TIMEOUT 5 /NOBREAK
DevManView.exe /enable "<YOUR GRAPHIC CARD ID>"
PAUSE
