C940 14" battery draining while completely shut down.

2020-05-26, 6:03 AM

Hi all,

 

Have noticed this since getting the laptop last November.

 

While shut down completely, the laptop loses battery power. I can have it fully charged, and if I start it up after a week the battery will be down to 93%. It seems to lose 1% per day doing absolutely nothing. I have disabled sleep mode, switched off the USB charging etc. but it still happens.

 

None of my other laptops do this.

 

Thank you.

No help from Lenovo support?

 

Just the usual crap service then!

Mmmm idk isn't 1% relatively good? Idk how other 10th gen laptops do overall but I have a Spectre 15 now which does the same. I've been convinced it's just in general that this happens with newer laptops but I'm not 100% sure.
