Power management woes ThinkPad x270

Running Lithium on a ThinkPad x270, I have two weird power management problems:

1. When I unplug the power cable, after 10-20" the laptop shuts down, even when the batteries (there are 2) are fully charged. This does not happen in BIOS, so I presume it isn't a hardware issue. If I manually suspend before unplugging the cable, it does not shut down... a reliable but annoying workaround.

2. When the batteries run down, the machine shuts down instead of suspending. My XFCE Power Management settings should cause it to suspend when the battery level hits 10%.

Thanks in advance for your tips.

Of cource!

For some months ago, I had to pull out USB cord for my Logitech BCC950 ConferenceCam before running suspend or hibernate. For maybe a year ago, it worked and now it works again, withut disconnect it.
Before, when hibernating with cam connected, the pc rebooted after writing memory to disk. If I had forgotten to disconnect cam, I had to enter BIOS and power off there.

It has happened sometimes that mouse has been frozen after waking up from hibernate/suspend on Lenovo Thinkpad. Mad a script to run in terminal, to unload mouse driver and load it again.

Also som years ago, problem with graphic when waking up My Thinkpads.

As of just now, no problems.

I have newer heard about your problems.

I forgot; It has happened that wifi wont reconnect to accesspoint on my Thinkpads after resuming.When that happens, I have to run script with nmcli to reconnect fast.
Just now, better drivers, two of my newer Thinkpads reconnect immediately. The IBM TP T43, takes about 30 s, to reconnect.

Works well enough on my x250 with ArchLinux.
TBH, 1. does __not__ sound like a OS issue to me, unless you have tested with other OS?
Have you changed batteries recently? Is the internal battery extremely run down? Etc.

2.: suspend to hard disk (a.k.a. hibernate) has to work. Doesn't without setting it up, afaik.
