Re: z51-70 battery drain

Welcome to the Forums Mohamed.

 

Open Resource Monitor and let the system idle. Is there any unwarranted system activity?
Also, does the system heat up significantly for no apparent reason?

 

Update us how it goes.

System Tray > Lenovo Energy Management > Go to Settings > Turn OFF Conservation Mode > Remove AC adapter > Reinstall AC adapter > It should charge up to 100%

 

Update us how it goes.

Re: z51-70 battery drain

I've had that happen on my Z570 more than once. What I have done is run the laptop on battery till it gets so low it shuts down.  I then plug it in and let it charge continually until it reaches 100%.

 

Update us how it goes.

Re: z51-70 battery drain

Do a battery gauge reset via following steps

 

Navigate to Power Manager --> Battery Tab --> Battery Maintenance --> Perform Reset. (Screenshot below).

If all of the above have been done and the battery still seems to stop charging at 98% or 99%, this is because of the system has been designed to do a slow charge to improve battery life span. Do wait a while and the battery will be fully charged to 100%.

 

Update us how it goes.
