Help with Laptop Freezing after removing power supply->Battery only work

[quartz38]

Hi Everyone,

I successfully finished install of Sierra 10.12.6 on a Dell Latitude E7450 and I am stuck with a Dell Latitude E5570 equipped with i5-6440HQ non Nvidia graphics, here is the problem:

I created a bootable USB key with Unibeast, modified the 0x432 variable, installed last Clover with everything got from a E7470 or E5470 install s(Kext and ACPI).

The laptop boot and is ready to install Sierra 10.12.3 but before starting the install when i am the menu with all languages moving, if I disconnect power from the laptop, it freeze and the crazy thing is that, if I start the same install with power disconnected and I connect it, it freeze the similar way.

This laptop is new and as been tested running well under Windows 10 without any problem if do the same.

I tried verbose mode in Clover, it seems that the system freeze even in the first beginning off the boot.

PS: I5-6440HQ is a real quad core but without hyper threading (usually I5 is dual core with Hyper threading) I don't know if this can explain something.

So .... I am stuck..

Many thanks for help if somebody has an idea.

PS: If i do not touch power supply I can continue through the install process. After install removing power supply has the same effect, freeze..

Sorry RehabMan,

In this case i have no file to attach because i can reproduce the problem in the first beginning black screen with the white apple.
So i think it is in the first configuration of Clover, after loading the EFI loader.

I tried yesterday with a live Linux, no problem wit disconnecting or connecting power supply on the laptop, so no hardware problem.

i am not aware of all concerning first Clover configuration.
If the problem appear at the first beginning just give me please the possible file to attach in my post.

Thanks

everything got from a E7470 or E5470 install s(Kext and ACPI).

Never use ACPI files from different computers. Extract/patch the native ones.
