Yoga 2.11 Won't Start without AC cord

It charges just fine. Once it starts up it works without the cord until it needs recharging (hours). However, whether it is fully charged, partially charged, or almost dead, it will not start up without the AC cord. Thoughts? Suggestions?

Re: Yoga 2.11 Won't Start without AC cord

Hi mamaflynn , 



Welcome to the Community Forums. 


Seems that the integrity of the battery is in question here. 


Step 1

Initially you may uninstall the Microsoft ACPI from device manager  and restart the PC. 


Step 2

Uninstall Energy Management from programs and feature under control panel . 

Check if this would allow battery alone to start without the charger plugged in.


Step 3. 

If the same issue , it may be the battery is starting to have issue , 

Check on the battery status from the command line . 

Lower part would indicate battery usage history and charge time.


You may check your covered warranty here and call in tech support for further repair option.
