Acer laptop - fails to suspend or hibernate

[DeIM]

I have B116-M laptop from Acer and gentoo-sources 4.4.6 kernel.
(have LXQT desktop but it seems doesn't matter)

I have problems with suspend and hibernate:
- when AC is on nothing works (suspend, hibernation, shutdown).
- when AC is off only hibernation and shutdown works.

Tried to search net and found this:
https://bugzilla.kernel.org/show_bug.cgi?id=66171#c6

Since I have xhci_hcd drivers built in kernel, I tried first and last of this kernel parameters:
xhci_hcd.quirks=270336

xhci_hcd.quirks=8192

xhci_hcd.quirks=262144

Nothing helped.

Tried to disable XHC1 in /proc/acpi/wakeup but not helped
XHC1 S4 *disabled pci:0000:00:14.0

(there stays only one line enabled and neither disabling it didn't helped):
PXSX S5 *enabled pci:0000:03:00.0

Is there something I'm missing? Thanks in advance
