C930 - Discharging when in use but connected to charger

2020-01-18, 8:40 AM

On top of battery usage which is not even close to the 8hr as presented by Lenovo, I also notice that my battery discharges even when connected to the charger.

Although I mainly use my C930 for daily office use, so mainly emails, some Excel and Word and browser activity. 

 

Anyone has ran into this issue and has resolved this?

Hi ,

 

Greetings!

 

Have you tried using a different charger? Does the issue occur while the computer is off? How long does the battery last? 

 

We suggest updating the BIOS and try using a different charger. You may download the BIOS from our support website.

 

Update us how it goes.

What charger are you using? Are you sure the output wattage is high enough? What about the USB-C cable?

Tip: You can also purchase a 45W or 65W AC adapter from Lenovo with USB-C. The Yoga Book C930 will draw up to 40W from a charger.

Hello, I have the same issue... I use the genuine Lenovo charger which came with the laptop. Charger specifications are 9V  3A... As I remember, Watt = Volt x Ampere... this means that the maximum output is 27Watt ! Far not enough.

Why Lenovo is providing a such weak charger ?

Hi C0lombine,

 

I have the same charger delivered with my C930 and when I use this I can work without an issue, the laptop is powered and charging at the same time.

Maybe you have a faulty charger or the charger does not receives enough power from the outlet ?

 

Also, do you use the USB cable that came with the charger ? I already had so;e issue with another charger/laptop where the USB cable was a data cable and did  not support the required power from the charger.

 

Hope this helps ?
