Lenovo IdeaPad C340-14IML huge battery drain while turned off

2019-10-31, 11:43 AM

Hello,

last week I bought the IdeaPad C340 (Windows 10 64bit). So far I'm happy with it. But unfortunately I'm experiencing some huge battery drain, while its turned off.

From 100% to 0% in 2 days without usage (the battery even lasts longer if its only in sleep mode :) ...).

The things I have already tried out (with no effect):

- disabling Fast Start in Windows

- disabling Always on USB

- installing the latest drivers from Lenovo.com (including BIOS)

- turning of the pc with cmd

- tried complete shutdown with holding shift while turning off

- changing CsEnabled in regedit to 0

Maybe I did a few other things I don't remember anymore.

 

I hope anyone can help me.

If I would send the Laptop back, I have to do it in the next few days.

(Sorry for my english btw.)

 

Thank you!

Hi!

 

Welcome to community forums,

 

Please open the Lenovo Vantage and run a system update and BIOS update if available. You may download the app here https://lnv.gy/33fXz1T. Once done, make sure to check for the battery health and see if the design and charging capacity of the battery have the same data. You may send a photo of the battery details, so we can check.

 

Regards,

Hi, 

 

I bought the C340 in January and for past month my battery is also draining. I full charge it and in 2 days it is sitting at 3% battery.

 

I have updated everything using Lenovo Vantage and Windows update.

 

I used to get 6-8 hours on battery saving mode when I am at uni but now the battery last between 4-5 hours before it runs flat.

 

Should I take this back to the place where I bought it? i need my laptop for uni and my assigments so I want to know should I take it in now or is there anything you can do to help me with this issue?

 

Here is screen shot of the my battery life.

 

 

 

 

 

Regards,

Johnny

Hey,

I'm sorry answering this late.
Unfortunately I had to send it back, because nothing fixed the Problem.
I ordered it again and everything works fine (already for a couple of months).
The battery actually lasts for a very long time. So I think there had been something wrong with the specific device I owned.

 

regards
