The keyboard backlight will only work in a dark environment, so you'll have to make sure you're not in a very bright location for it to illuminate.

MBP 1,1-10,2 Permanently Disable 2011 15"/17" MacBook Pro Dedicated GPU - gMux IC Bypass

Of course you can run any virtualization software. And it runs nice, as you know.
He means to install Windows native, as in BootCamp. If you have the discrete GPU disabled, it´s not possible.
Hey Mr. Dos question for you? do you know the measurement between pads of the macbook JTAG, I am ordering a pogo pin so that I can purchase one of your licenses, ive scoured the web couldnt find the info i needed and don't want to buy more pogo pins then I need to find out the size, lol.
Get this one, it works well for this: https://www.ebay.com/itm/263276278399
does anyone want to try coreboot/tianocore method to disable the dgpu? (and still run osx montenry with HD4000 etc?) for macbook8 is not as good because the spi is at the keyboard side.. while macbookpro10 is on the side easily accessible without disassembly
@dosdude1 I went to use my late 2011 mbp (with disabled gpu, running catalina with your patch tool) the other day and noticed that the keyboard backlight doesn't work. The buttons still cause the display to show that the level is being adjusted, but the backlight for them doesn't come on.
Do you know what might be the issue?
Thank you.
Edit: Hah, I had a feeling I'd asked about this before. I did, on the previous page. I just turned on the mbp again to check and they keyboard light doesn't work though. I duno.
Edit 2: I tried to boot to recovery (cmd+R) to try and maybe run first aid on the drive (?) but the mac won't do it. It just stays on a white screen...

This is only if you have it set to behave this way. In settings, keyboard, you can choose to have the ambient room light affect the keyboard brightness / auto-dim/brighten. Mine is not set like this, and never has been. I always have it set to manual brightness.
So this was not this issue.
Then it must be a hardware issue. Check the ribbon cable right underneath the fan closest to the optical drive, ensure that it is fully inserted. Otherwise the actual keyboard backlight sheet may be bad.
I will check that out. I just recently changed the battery to a brand new NewerTech NuPower one, a calibrated it. Doubt I would've knocked anything loose then, but I may have happened before. I'll check.
Thank you.
I used images I found as reference. I checked the cable, it appeared inserted well. I lifed the connector hinge, and gently removed the cable. I gently wiped it with some iso, dried it, and then carefully reinserted it, test gently to make sure the it was indeed fully inserted. Then I closed the hinge.
Started up the mac, no keyboard backlight. Damn.
Is there any way I can test the backlight sheet relatively easily, like with a multimeter somehow? I'd guess probably not.

Thank You for the firmware patch. It was fun to do, and my wife is thrilled!
Hi Collin,
Thanks for ur efforts for saving saving planet, I have macbook 2011 15 inch I applied ur patch successfully but often screen goes black applying again all process of patch it goes back to normal , I have disconnected even battery and trying to understand running directly with Magsafe , sometime cmd S or cmd R does not work or sometime it does not recognises alt command.. very weird .. Any idea please why these commands are consistently followed , I am planning to disconnect LCD connector and see if there is any issue please. I have also noticed the cd drives does not work as well possibly will disconnect the same as well. Keyboard was tested and seems fine was wondering if u have any pointer please.
Please note that this patches once tested few years back I have never used machine (of course battery was disconnected) but recently started using and faced the issues. the machine goes black after running few hours or few days, to me it looks the display is gone black but machine may be running .
Cheers
raky

It sounds like you're just relying on the NVRAM patch and potentially have removed R8911? If so, that's your issue. Applying DeMux firmware will permanently disable the GPU. Otherwise continuing to re-apply the NVRAM patch when it gets reset is expected, as it is only temporary.
Hello from Brazil,
I have a MacBook Pro 17" A1297 2011 with the defective gpu. I disable it following the dosdude tutorial (nvram one) . A few days I left the lid open and probably went in sleeping mode then screen froze, and after forcing a shutdown it won't restart.
When I press the power button, the front white light (left of the two) is bright for about 1/2 second then goes 50% duller. The fans start up, the cd drive makes noise, but there is no chime and the display remains black.
The battery and charger are OK.
It seems the system has some form of function as when left with the led on, the CPU area on the aluminum case heats up, and if leave to heat up the fan kicks in to cool the system, then the system cools down.
I have tried an SMC and Nvram reset.
I've noticed the keyboard does not appear to respond to input - caps lock doesn't light up or the keyboard backlight or disk ejects do not work.
I've tried disconnecting the battery and running off cable power and this has no material change of effect. I also tried clean the ram memory. After several tries or if I left the Mac for hours I power it on and it works fine, but I can't turn it off or restart. The question is, if it is due the defective gpu or it could have a motherboard issue. I want to permanently disable the gpu but I don't know if it will solve both issues.

I had the same thing happen to my 15" Early 2011 MBP. It had been used daily for years with the "set NVRAM variable/move the kext" fix. Last year I replaced the battery with an aftermarket one, and it seemed to work fine. IIRC, it was several weeks later that it woudn't boot, not even into single-user mode, with the same symptoms you describe. I never got it to boot again, and have pretty much given up on it.
All I can add is that it does not appear to be a problem with the internal SSD (the original, 256GB), as I removed it and it seems to work OK as an external drive on another Mac.
Hope someone else can enlighten you further...

I can boot in single user mode or reset nvram but the problem is I have to try several times to start. I discovered if I leave it heat up and then cold down it will starts at first try.
