HD4400 = Very slow wake from sleep after 10.14.5 update

[bisk]

Hi all.

 

Since running the 10.14.5 Mojave update, I am now experiencing VERY slow wakes from sleep, usually 10+ minutes. I'll push the power button to wake up and the LED will come on solid but the display will remain sleeping for at least 10 more minutes.  Everything was working perfectly under 10.14.4.

 

This is on a Lenovo ThinkCentre tiny form factor M73 desktop with the Core i3-4130T CPU (HD4400 video).

 

I updated WhateverGreen to the latest version 1.2.9 but this makes no difference.

 

I have a nearly identical system, Lenovo ThinkCentre tiny form factor M93p with the Core i5-4590T (HD4600 video) and it sleep/wakes just fine.

 

I do notice that on the i5 system, the registry shows an av-signal-type value of 02 while on the i3 system that same value is 08 but this was the same under 10.14.4.

 

Anybody else experiencing sleep/wake problems with the HD4400 under 10.14.5 ?

 

Thanks in advance
