How can I switch the GPUs?

[Dieter.koenig]

Hey. So I have an Hp EliteBook 8460p laptop but it's dedicated a.k.a discrete Radeon HD 6470 got burned up and doesn't seem to be working anymore. So I tried to install the Intel HD 3000 iGPU drivers as those are the ones that the Laptop CPU (i5-2520M) supports from the official intel page but had no success then I tried to install the drivers manually from the Device Manager but it looks like it doesn't detect the iGPU from the laptop? (https://prnt.sc/ru7ns3)

I'm running on the Microsoft Basic Display Driver (https://prnt.sc/ru72fl)

Which I think it should be the iGPU one but no programs or any game does detect that GPU.

Maybe due to how switchable graphics is implemented, the iGPU cant work on its own for some reason (which can be a thing for OEM stuff, that's why they are so difficult to troubleshoot sometimes)

 

Try get into the BIOS and see if you can force to run only the iGPU

What am I supposed to do now? I wanna use it for Nvidia GeForce NOW cuz I know the iGPU is so weak but it doesn't find any graphics on the system.
The BIOS of this actual laptop is way more limited than the Nokia 3310 options. Wouldn't even call it as BIOS.

Can you still use the Radeon drivers? If even that doesnt work, then expect another laptop.

artifacting, usually caused by VRAM going bad and rarely the GPU itself.

 

Also the iGPU maybe disabled on a hardware level if this laptop never had switchable graphics in the first place. You could also check whether there's a hardware switch somewhere for switching the GPUs.

I know what are they caused from. The problem IS , there's not any kind of GPU switches to switch those GPU as I could see.

Did the laptop have switchable graphics back when everything works? If it doesnt then you could assume the iGPU is just disabled from the beginning, and currently the Radeon GPU is running fine only because the clock speeds are very low.

Not really as I am aware. When I first bought it, it only had Radeon HD graphics drivers installed and no other drivers as I remember. I thought I removed completely the drivers and it's control panel from existence as I know? I even disabled them from Device Manager and stopped them getting installed from Windows Update with DDU or https://i.ibb.co/1dcB5q4/20181205-221928.jpg this

I hope you are right. Because, you actually make sense. But I wonder how could I check what GPU is my Laptop using.

without drivers, rather difficult. Run CPU-Z and go to the graphics section, does it show what GPU you have? I'm not sure if it will work properly when there are no drivers (MS basic one doesn't count), but in my case (my laptop lacks switchable graphics) I cannot see the iGPU even though I know the 8750H has one in the piece of silicon.

That's what I'm talking about, despite the fact that this CPU already have an integrated GPU in there but the Windows 10 won't still detect it. On Intel's Drivers downloading center there's no option for Windows 10 operating system drivers for this certain generation. So logically it means that those drivers shouldn't be working on Windows 10 right? It might sound right but some people on Youtube managed to install the Windows 8 drivers of Intel HD Drivers to Windows 10 manually from Device Manager. But there's still one guy who had similar problem who even he himself thought it should be that Windows 10 isn't supported but yet he tried to downgrade his Windows to 8 and 7 but didn't managed to make it working even using the proper drivers for it's supported Windows. I know this might sound way to exaggerated but trust me the laptop is the only "PC Device" I got left after my Desktop Computer's GPU failed. And on those pandemic states it's kinda hard to provide the needed parts, no matter physically nor financially.

This is what CPU-Z shows on the Graphics tab: https://prnt.sc/rwefog

In case you need more infos, there's what it shows on GPU-z https://prnt.sc/rweu50

Not that it doesn't detect it, but the iGPU is disabled from a hardware level and cannot be enabled. Not being able to detect, being disabled and not there at all are 3 different cases.

 

CPU-Z will let you select the iGPU if it is enabled, so seems like this laptop never had switchable graphics and iGPU is disabled from hardware level (i.e. fuzed off) then.

Does it mean the Laptop is using still the dedicated Radeon HD GPU? The only thing I did with this Laptop and after some days the GPU show off that screen was cause I tried to overclock the Laptop Display puting like 10-20 Hz more each try until there were showing some little boxes kind of artifacts and I immediately reverted it back cause it normally means it was on dangerous zone but after some days the GPU stopped working and couldn't use it more. But isn't the Display supposed to break instead of the GPU? I'm not really sure how this Laptop is on what running now but since you say the iGPU is disabled and it should be running on the dedicated Radeon GPU on low clock speed then it must be ? The VRAMs should have been damaged due to overclocking the display as it looks but GPU may seem to still be working but only on low clock speeds?!

They are separate events

Yes. Installing the drivers could cause a fail because during the installation (and every boot), the GPU will momentarily enter 3D clock speed, i.e. the base clock of the GPU, while without the drivers it will stay at idle clocks.

Again, unrelated problems. Overclocking the monitor only affects the display drive circuit and not in a way that affects its lifespan. Besides when a display drive circuit breaks, there wont be display outputs no matter what refresh rate you use.

Then what did it caused it to fail? It started to do those artifacts pretty much after I overclocked the Display, I've heard when Display Monitor has more than 60Hz the GPU should be working twice as faster to be delivering the visual informations on the screen If I am not wrong? So this overclock should have pretty much damaged the mobile GPU while I could even see back then the artifacts on higher refresh rates. btw I've ran some tests with Intel's diagnostic tool and it shows like this https://prnt.sc/rwfk05 Just to confirm that.

P.s: The problem of all this drama is the fact that no program or game actually detects any GPU on this Laptop.

Age, time kills electronics.

 

It may be pushing twice the data into the monitor, but that's like running an ethernet cable 24/7 rather than an hour per day. Makes no difference. The compute cores dont work harder either since frame rate has nothing to do with monitor's refresh rate.
