[BUG]: Battery mode is reset on rapid charge after each reboot

BIOS version

What's wrong?

I've set Battery Mode on Conservation, but sometimes after a reboot, it reset itself on Rapid Charge.

I've made a log, but I'm not sure it will be useful as the problem occurs randomly and only after a reboot, and then the application is started by the task scheduler and is not in log mode.

How to reproduce the bug?

Go to power mode, set battery mode to conservation reboot The battery mode is now on rapid echarge

What is the behavior that you expected?

Battery mode should be remembered.

Looks like the same case as #120. You can try working around this with actions or resetting EC might also help sometimes.

OK, I've added the action when the power adapter is connected. Is it run if the power adapter is already plugged before application launch though ? How can I reset the EC ?

[mooms06]

Also, I should mention that I never encountered this bug with Vantage, so I'm not entirely sure that this is a bug in the BIOS.

[BartoszCichecki]

Yes, it will run when adapter is plugged in, but also LLT starts when adapter was plugged in before.

About the EC reset I recommend that you join the discord server that is mentioned in README, people will guide you how to do it.

Regarding Vantage, it is a bug in BIOS. LLT doesn't store any settings - it always loads settings directly from FW/EC/Drivers.

OK thank you. I've already joined the discord server.
