Power management on HP EliteBook x360 1030 G3

[Focke Christian]

Hi,

my HP EliteBook x360 1030 G3
1. often refuses to suspend (I have to trigger it twice or more often)
2. often wakes up without any external trigger (lid opened / key
pressed)

Questions
i. What may be the reason for this strange behavior?
ii. How to investigate it? (I found nothing meaningful in syslog.)

I am running Debian 10.2 with GNOME on Xorg, if that's possibly
important.

Thanks for all hints, Christian

P.S.
In all my Lenovo ThinkPads I've had before, suspend / wake up was never
an issue.
