Yoga 900 Battery Draining after BIOS 3-13-16 Update

Has anyone noticed increased battery drain after BIOS update dated 3-13-16?

 

I updated the BIOS and also reset the BIOS defaults and I am still seeing increased battery drain.

 

Thanks!

Ok guys I think this is a Power Management issue. My battery meter is erratic goes from 100% to 92% then 89% in about 30 minutes.

 

It never did this...any ideas? Thanks.

On 3/11/2016 there was also a updated Lenovo Battery Guage released.  Try uninstalling your old version, reboot and then install the latest one.

 

Here is a link to the Battery Guage download.....

Oh well...I used to have awesome long battery life on this laptop. Now it is ruined! I guess I will wait for another BIOS or Power Management update.

After you mentioned of a BIOS update being available I went ahead and updated my Yoga 900 last Tuesday.  So far I haven't seen any ill effects on battery life.  Did you try doing this soft reset of the BIOS? ....


1. Unplug the charger / adapter.
2. Press and hold the Power Button for 15 seconds.
3. Plug in the charger / adapter if needed and power up the system to see if the problem was resolved.

The fix that worked for me was something I did just a week ago. I restored the laptop using the lenovo button. It wiped all my apps and set it to factory default...and it worked!!! Battery life was restored!

 

I did notice that the BIOS was still the 3-13-16 version, so it may not have been that! I would say try and restore if you have you laptop backed up...Good Luck
