Lenovo s730-13IWL battery discharge when power off

2019-09-24, 6:40 AM

Hi, I have s730-13IWL that looses battery charge when turned off (around 10% per 24 hours).

 

What I did so far:

- Diasable Windows fast startup;

- Turned off Always ON USB from BIOS;

- Disable WIFI from BIOS.

 

The system is with BIOS version 8HCN33WW from 11 Jul 2019.

I can`t find any older version to try downgrade.

 

When I serch the forum it looks like this is a common problem with alot if Lenovo models.

I am also working with HP, ASUS and Huawei laptops and they looses no more then 2-3% per week if not used..

 

Any suggestions on how to fix this or where to find previous BIOS?

Yes, we are in same situation. I thought my softwares and may be sleep mode consuming battery. I have to recheck it.

Thanks.

Hi, thanks for your reply. Unfortunately the solutions there didn't help me. It looks like when the drain is huge (like 30% per night) the most common reason is that the laptop is hibernated or in sleep mode. When the leak is small it usually comes from AOU function or BIOS bug. I have tried to turn off AOU (as everything else that can be turned off/on in BIOS) but without any luck.

My unit bought in May 2020 also facing the same problem. As I don't use it over weekends, the battery is heavily or totally drained on Monday mornings. Any solution on how to stop this issue? Lenovo support?
