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

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 Smiley Happy ...).

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,
