Dell mobile Precision 7510 Intel hd530, black screen

[Jake Lo]

Perhaps only occurs with Nvidia and not AMD/ATI cards...

I tried removing the discrete Nvidia card, but system won't even post. Sigh...

 

On the brighter side, I think I do have QE/CI with the M2000m even though VRAM only shows 0MB and only displays to the external monitor through HDMI.

It won't even detect the internal LCD.

@ Jake

I have patched my DSDT before with many laptops. using the clover f4 option. but with 7510 I am unable to create a correct one. can you refer to me the correct guide. would like to disable Nvidia via dsdt for my lighter and battery usage.

 

for M2000m have you tried with Inject NVIDIA=false,  with IntelBacklight.kext in clover folder and AGDP fix. I got my M1000M working with web driver with  these setting. Ideally it should work. I wanted M2000M but didn't go because of the budget.

 

with M1000M i still get black screen at the end of boot. the login screen appears after i close the lid and reopen. this i has to do for only NVIDIA not Intel HD530.

hi sameer,

Have you create DSDT in clover by using F4 but it doesn't create any file ?

I have used other EFI to create them and get some files in ACPI/origin, you can try that.

and I attached my files in origin folder if you need.

 

p/s:

Use USB to boot this EFI,

in Clover GUI, press F6, wait 2s -> press F4 wait 2s -> press F2, it will create file on USB

@Lamcrkh516

what are the patches you applied to your DSDT?

I haven't created DSDT patched for my 7510, I'm reading some tuts how to do that.

Use this to disable the nvidia card in your DSDT.

@Jake,

can I use this to diable AMD FirePro ?

[Jake Lo]

Probably not. Can you boot to Clover, hit F4. The compress and attach the Origin folder in /EFI/Clover/ACPI

[lamcrkh516]

I had attached them above post Jake

[Jake Lo]

Try this, backup the current Config and replace with attached. Place DSDT/SSDT in Patched folder, boot with Switchable Graphics enabled
