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.
