E430 does not resume from sleep

BIOS Version: 2.60, 6/14/2018

SMBIOS Version: 2.7

OS: Windows 7 Pro 6.1.7601 Service Pack 1 Build 7601

 

My laptop consistently fails to resume from sleep:

  • I hear what sounds like the CD drive "hit" (there is no disc in the drive). I believe this is a normal sound when powering up.
  • The display remains black.
  • No keypress has any effect. CTL-ALT-DEL has no effect.
  • Power button has no effect.

All system updates have been done.

 

From other posts I have ensured that power options NEVER allow the laptop to enter sleep due to timeout.

 

To reboot I disconnet AC, remove battery, install battery, connect AC, and press the power button. I verified that I can successfully reboot either on battery alone or AC alone.

 

System logs only show messages at boot time indicating that the system was not shutdown properly.

 

Any thoughts?

 

And we're back...

Move delayed but still coming
