I'm unable to login when waking up (X minutes to login), and the battery is drained in the morning. This happens sporadically and I can't figure out what triggers it. Last night I noticed that the power button was lit through the closed laptop lid. I rebooted the laptop (hard reset, long-press on power) and closed all applications, but it continued anyways. I have a T460 with the LTS Linux kernel, and I run TLP for power management.

Is this a bug or is something truly trying out passwords? What can I do to figure out what is trying passwords?

I appreciate your help in figuring out what is causing this, let me know what extra information is required, thank you.
