Title:
  Dell Precision 7730, sig=0x906ea/20200609, System hangs when resuming
  from S3 if in battery mode

Status in intel-microcode package in Ubuntu:
  Confirmed
Status in Fedora:
  New

Bug description:
  Sku: Dell Precision 7730
  BIOS: 1.12.1 (11/11/2019)
  Kernel: 4.15.0-1081-oem & mainline 5.7.0

  1. Boot up the system(with AC or Bat only)
  2. enter S3, unplug AC if plugged, can't wake up the system
  3. enter S3, plug AC, the system can be waken up by power button

  Can't reproduce this issue with the intel-microcode=3.20180312.0~ubuntu18.04.1 in bionic repo.
  After upgrade this package to intel-microcode=3.20200609.0ubuntu0.18.04.1 or the previous version leads to the resume hang issue.
