Yoga 900-various battery status in short period time

2016-02-13, 23:56 PM

Hello guys 
 

It seems that i am not getting any accurate informaton about my baterry status and how long my yoga should be working: Sometimes on 99% it tells me that 3 hours left, on 94% the battery status is 8 hours and four minutes left and on 93% it tells me that i have 6 hours of working. 

between this presentage i havnt change anything from the power settings and it always remain fixed on balanced and 60% brightness. 

Therefore i think my battery is defected or needed collabration. how do i do battery collabration on my yoga 900?

I don't see an option on Lenovo's support site for a battery collabration. However, there are power management software on the site that might help. 

Try downloading these:

Hello,

 

It's normal.

These 2 driver installations end up running the same acpidriver.exe file, which installation is... invisible.

Sorry, my information was incorrect.

 

The installation of the driver is "invisible", only if it is already installed.

You can check the driver installation and version in Device Manager, System Devices, Lenovo ACPI-Compliant Virtual Power Controller.

You already have the latest version, so you don't have to upgrade the driver.

 

Actually, when you run the installation file again, it doesn't complete and generates an error, that's why nothing is visible.

To run it with no error, you would have to uninstall the Lenovo ACPI-Compliant Virtual Power Controller driver, check the box to delete the driver files, reboot, and run the installation again.

 

To calibrate the battery, I only know one method: completely drain it, then completely charge it.

I don't say it will solve your problem though.

If it's under warranty, Lenovo should be able to fix the issue for you

Hi Shaykea,

 

There could be a couple of reasons this is happening.  

 

Windows shows the amount of time left depending on what you are doing on the computer at that time.  If you are watching movies, it will show less time than if you were doing nothing.

 

Is Windows downloading updates?

 

One thing you can try is from the desktop open Task Manager, (Ctrl, Alt, Delete) and see what your cpu usage is.  There could be processes running in the background that are eating up the battery.  

 

After Windows is done updating and it reboots, I suggest rebooting again.  Sometimes the updater gets stuck and uses up cpu.  This can be seen in Task Manager.

 

Regards,

Dave
