E6230 OpenCore sleep failure on EFI


Recommended Posts



I am using Catalina(10.15.6/19G2021) on Dell Latitude E6230, BIOS version A11 (no battery for updating)

The wifi chip is DW1510, BT is DW380


The patched DSDT cause the machine to boot and the screen will go dark when it reach the login screen.

As a result, I worked on a dynamic (hot patch) DSDT


Backlight, audio, trackpad, USB3, ...etc are working nicely. Also the boot time is way better than Clover.


BTW, The backlight hotkeys(fn+arrow up/down) (IOWMIFamily) haven't work yet for now, but I will be working on that and will update soon.


Except when the machine go into sleep mode, It restarts with this log

I appreciate all your help.

Thanks a lot.


A few side questions:

- The machine always restarts on shutdown, even when I shutdown with an Arch Linux live usb, Resetting BIOS default/EC Reset doesn't work for me. Does anybody have the same issue? I think it has something to do with my battery, which cannot even hold any charge.

Recently got backlight hotkey working. Here is the EFI folder (A11 BIOS)


The sleep issue still persists.

P/s: for anyone struggling with this issue, you can try Block Sleep (S3 state) from BIOS. It works. Can't fail if you don't sleep at all :) (Mind your power usage if you are running on battery)


Before using this patch, please make sure that the ACPI patch _OSI to XOSI is done correctly because the number '14' is DSDT-dependent(BIOS version ig).


The issue is that "\SB.OSID" would be compiled to "SB_OSID" which makes the replacement done incorrectly

P/s: you might want to checkout iasl -l (the lowercase L)


P/s2: The sleep/wake failure issue still persists even on A20 BIOS, updating BIOS might cause Wifi and Bluetooth to stop working. However, if you still want to do so, you can fix the issue by using SSDTTime to generate FixHPET patches for the dumped DSDT(use linux), remember to add the new ACPI patches and remove the old ones from config.plist. Block Sleep (S3 state) should stay ticked. It glitches the graphics on shutdown.
