Hello,
My laptop (hp Elitebook 840 G8) recently underwent a motherboard swap, due to some damage to the usb-c ports.

After the swap, the system worked fine, but for two aspects, which I suspect are related:
1. I cannot suspend (s2idle) the system, as it just powers off and I am forced to "reset" the motherboard (hold the power button for 30s while off) to make it boot again - but only if I'm not connected to a dock.
2. The battery just drains for no apparent reason, even when the laptop is compeletely turned off.

Probably the second is some bios setting, but I though I'd mention it anyways.

As for s2idle, here's the output of `journalctl` after issuing `# systemctl suspend`:

The fact that this happens only when disconnected from a dock is a hint that this is a software problem. But what to do?
Any suggestions on what to do?

P.s. System is up to date
