Black screen after sleep / display close

Question

Black screen after sleep / display close

johnhoogeveen opened this issue 5 years ago · comments

I am using the same ProBook 650 G1 and all seems to be working find except my display.
After closing the lid it stays black when I open the lid, the backlight is working, brightness control is also working but it all stays dark.
I used the procedure from rehabman (hotpatch) and also used your EFI files but no luck.
Any ideas how to fix it?

It works for me ok. Even on macOS Catalina there is no problem.

Do you have any specific settings in the bios, this is my 2nd 650G1 with this issue, my 450 G4 works perfect using a similar setup.
Catalina will have to wait a bit till this issue is fixed, I need to restart to often using my current setup :-)

I set it according to BIOS settings in Rehabman's guide.

Ok, I double checked the settings, they are like Rehabman's suggestions.
Upgraded to catalina today, al works great with your EFI except the display issue
Guess something else is wrong, I will close this issue

What BIOS version do you have?

I am using bios L77 1.49 in UEFI mode with CSM

New version of BIOS can change DSDT a SSDT tables so maybe the patch doesn't work for newer versions. You can try to downgrade the BIOS to L77 ver. 01.46 (which I use) and verify if it works. Other than that, I am not that skilled to help you, sorry.

I think you can get some help if you start a thread on https://tonymacx86.com.

I will try the downgrade later and keep you informed, there is already a topic on tonymacx86 but no success yet.

small update, downgraded the bios to 1.46, that dit not fix it.
Cleaned the entire disk and reinstalled Mojave using the Rehabman method, this also dit not fix it.
I noticed something, with Rehabman's method I am running a MacBookAir6.2, with yours a MacBookPro11.3. Tried that EFI to, same issue with the internal display, external however works, with the displaylid closed everything is displayed on the monitor.
I will monitor the threads I made on insanelymac and tonymacx86 to see if a guru can help me

That's odd. There is one more difference I just noticed - the CPU I've got is 4200M, you've got 4210M.

Hello,
Can you do me an favor and check what displaypanel is inside the probook with this command in terminal?
ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6

I found it on this website http://osxdaily.com/2010/07/28/find-out-what-model-lcd-panel-in-your-imac-macbook-macbookpro/
The laptop is still working great, Wifi adapter is replaced by your suggested model and also works perfect. Only the LCD panel is not working after wake (my external monitor does work correct so I guess it is not an issue with the HD4600 but with the panel itself)
