Bricked laptop gpu

[Looterin]

Hey, so my laptop gpuvis all bricked up cause I tried installing another gpu bios on it. Will connecting another gpu help my laptop actually display something so I can go into the system and install the default bios into my graphics card 

[Hachi_Roku256563]

how are you planning on connecting another gpu to it?

Does your lpatop have an igpu

What model of laptop?

Does the laptop still POST (just not display anything)?

[Quackers101]

umm, most laptops you can't change GPU so please give more info and details.

also I guess if this was a supported feature that needs BIOS update, if not you talk about GPU drivers?

also was it an external GPU?

Mine is a gaming laptop with no igpu. Like I want to connect an eGPU, while the dedicated gpu is removed so it will use the eGPU as the display adapter

My laptop does not display anything. I haven't tried it yet. My gpu is bricked. My laptop is a hp omen-dc1088wm

I don't get what you just typed. But you can actually change the gpu by removing it. But you'll need a professional. You use a hot air gun and make the  tin use to stick the soldered gpu melts then use flux to put another one then dry it with hot air gun again.

I have a dedicated graphics card but it is bricked up because of I tried installing a new BIOS on it I want to remove the bricked up GPU and use an external GPU also known as egpu so I wanted to know if the laptop will automatically use the external GPU as the display adaptor

Your issue sint with the die, its with the vbios chip.

Right now the best corse of action is to take apart the laptop and find the gpu vbios chip, then get a bios flashing tool and use a arduino or pi to flash it.

I thought there was no fix. Is this actually a fix?????

Also can you be more clear i don't understand what to do yet

There may be.

There is a seperate chip that stores teh gpu bios.

You may be able to locate it and flash it with a working one

How do I know the difference between cpu bios and gpu bios

motherboard would have an BIOS at least for desktop users (not sure about laptop BIOS setup).

Were you restart and go into the BIOS menu, which goes for everything connected like GPU, ports, CPU, RAM etc.

I guess the vBIOS is just on the GPU itself? controlling how the GPU works, if you ever messed around with vBIOS or any BIOS updating you should know the risk?

this is kinda how it works, don't take as truth or if this is what you should do.

or if to recovery and follow how it's done on a full desktop GPU (a bit similar)

Just check hp omen 15-dc1088wm

That computer has a

Intel® Core™ i7-9750H

Which has a UDH 630 IGPU

However it does not SEEM to have a DGPU

so the IGPU is the problem

This menas that it cannot be removed though

My old laptop Asus ROG G751J has an iGPU on paper but it is disabled with no way of enabling it, only the Nvidia card can be used.

@Looterin

Are you absolutely sure you can't switch over to iGPU on your laptop?

Does your laptop still boot up? There is a chance it is making it all the way to Windows with a borked BIOS flash and no image on the screen.
I found myself once in that kind of situation and managed to re-flash the BIOS practically blind (on that Rog laptop I mentioned above). Here is what I did and what you could do:
- Turn off the laptop.
- Reset the router and wait a few minutes for all of your network devices to connect.

- Use another PC and check the DHCP client list, memorize it or save it somewhere.

- Turn on the laptop, look at the power LED (should be on) and the HDD/SSD activity LED (should be flashing occasionally, if you have one), wait a minute or two.
- Use another PC and log into the router again to see if the borked laptop shows up on the DHCP client list (look for a device that wasn't previously there). If you see it there then proceed to next step. *In case you've manually set up your IP address on that borked laptop then just continue to the next step.

- Now you might want to ping the laptop, but that wouldn't do much since I believe Windows 10 Firewall blocks ICMP requests by default, you most probably wouldn't get a reply even if the laptop was in perfect running order. Instead, continue reading.

---- From here it gets more complicated / less user friendly ----
- If you've got a pin / password protection type it in blindly on your borked laptop and log in.

- Just to make sure you are in Windows and you've got access to a command prompt you can:

setup Wireshark on another PC in your LAN

then on your borked laptop blindly type in Win + R 

then type cmd + ENTER 

then type ping -n 1000 <ip address of that other PC on your LAN> 

then on that other PC run Wireshark and sniff for ICMP packets on your LAN coming from your borked laptop.

(here is an example of how you can filter the packets in Wireshark, just replace the src addr with the one of your borked laptop):

icmp and ip.src eq 192.168.1.100

If you see your borked laptop sending pings you've got a good chance of unborking it, here is what it would look like:

Spoiler

* no response found because like I said Windows firewall is rejecting the ICMP requests by default, but I can still see that .221 is trying to ping .121

---- The fun part, batch files ----

I'm guessing you used a tool like NVFlash to flash the BIOS, you can put that tool and the proper ROM file on your USB flash drive and make a batch that executes the tool AND redirects STDOUT/STDERR away from the command prompt to a text file on the flash drive (or ideally to a network drive, if you have one mapped like I did). Anyhow the point is that the flashing tool will probably have some prompts for you / hints what you can do... but without an display you have no way of knowing what the tool is asking / telling you... example:

Spoiler

So by redirecting all output to a text file you can read that output on another PC.
WARNING! DO NOT unplug your USB flash drive while it is flashing your VBIOS! After each command you type in blindly into the flashing tool wait 10 minutes just to be absolutely sure you are not unplugging it while it is still flashing.

You might be wondering how will you run that batch file... blindly is the answer hah. One practice batch (with no flashing involved) on a working PC, once you've mastered that you move on to your borked laptop.

 

I didn't include the batch file I made, if you end up trying this route and your laptop actually goes all the way to Windows I will try to find that batch file and upload it for you, if I don't find it - no worries it isn't too hard to make one from scratch.

PS I hope you at least made a backup of your original VBIOS before you flashed a new one...
PPS Next time, spend more time prepping things. If I setup a bootable drive beforehand with my backed up rom file and auto-executing flash tool I wouldn't have spent a whole afternoon dicking around... Or perhaps an even better advice, just don't mess with VBIOS on laptop GPUs, not worth the hassle (I ended up squeezing out like 4-5% more out of my GPU).

I dont understand 1 bit. But yes I have a backup of my gpu bios

Simplified version:
Even without getting an image on your laptop when you power it on there is still a chance the laptop makes it past the POST and goes into Windows, you just don't see it. If that is the case you can blindly attempt to flash your original VBIOS and get everything back to the way it was.
That being said, some people can be helped and some can't be helped (someone else needs to do it for them)... this whole thread looks like the case of the latter one, best of luck to you.
