lenovo yoga 900s repeatedly shuts down when battery is 20%, and turns on with 0% battery

2018-03-17, 20:38 PM

hello, 

Ive had the yoga 900s for over a year, and in the last few weeks, suddenly my battery is acting out. I can charge to 100% and it works fine until around 20% when it suddenly shuts off with no warning. I concect the charger, and turn it on - the battery gauge always states 0%. 

 

why did this start happening - is ther something I can do, or do I need to get it to a lenovo center?

 

thanks,

Nir

Welcome to the forum.

 

why did this start happening

 

Most likely a cell in the battery is short-circuited.

 

Go into Lenovo Vantage -> Hardware Settings -> Power.

What is the indicated condition of the battery?

Can you post the Battery Details report here? That may offer further indications of what the issue may be.

 

is ther something I can do, or do I need to get it to a lenovo center?

 

You probably need a new battery. Unfortunately batteries are only warranted for one year so this would be at your expense.

I'm surprised by the "Good" rating. The battery Full Charge Capacity is only 60% of Design Capacity and the cycle count is 244. That suggests fairly heavy use. It's probably time for a new battery. Fortunately it's quite easy to replace the battery. See the Hardware Maintenance Manual for details.

 

(For comparison, I have the same battery in my Y900s. The battery is a month older but FCC is 92% of DC with only about 40 cycles.)
