    Razer Blade 15 Gaming Advanced RZ09-0421 Laptop - No Display, External Screen Only

    Hello Colleagues,

    I'm dealing with a perplexing issue on a client's laptop and would appreciate your insights. The user experienced a sudden screen blackout during regular use (not gaming), although the laptop continued to operate normally otherwise, with music playing and indicator lights active. An external display connected via HDMI works fine, indicating the display itself is functional. The device manager shows the Intel XE GPU as disabled, with Windows reporting a related error, while the NVIDIA RTX GPU operates without issues, even supporting gaming.

    Upon inspection, the motherboard appears immaculate - no signs of liquid damage, burns, or missing components. This is the first time the unit has been opened. I've attached photos for further examination. Interestingly, I haven't encountered a scenario where the Intel XE Graphics is disabled due to a hardware fault; it's typically the opposite.

    During boot, the Razer logo doesn't appear, and there's no visual output in BIOS. I've attempted to detect any images using a strong flashlight, but to no avail. Remote access through TeamViewer (without HDMI) shows no monitors in the device manager, aside from the noted disabled Intel GPU. When connected via HDMI, only the HDMI output is recognized as a monitor.

    The laptop is slightly over a year out of warranty, and Razer won't accept it for service. I've included photos and taken various measurements. I haven't tried a different LCD yet, as there are no apparent physical damages to the LCD, ribbon cable, or connectors. BIOS and EC are up to date.

    I'm looking for any thoughts or suggestions on this issue. The specific model is RZ09-0421EED3, and the motherboard is APF21006_MB MP V4.0.

    Thanks in advance for your input.

    NVIDIA GeForce RTX 3060
    Intel Iris Xe Graphics
    12th gen Intel® Core™ i7​

    Cheers​

          Hi mate, I don't have the board any more, but if I didn't, I'd take a risk and replace with same value as the one above it.

            The one on top is 0 Ohm, I tried it, it doesn’t start the matrix

                  Computer in question : Razer Blade 15 2020 Base Model
                  Model# RZ09-03286E22
                  BIOS CHIP: WINBOND W25Q128BV

                  What I'm trying to accomplish:
                  I want the computer to properly boot with an external display with the attached display disconnected from the motherboard. I have a CH341A programmer and full capability of modifying the BIOS easily. I Have tried various setting changes to no Avail.

                  What I've tried thus far: Too much to note and I really dont remember everything I changed but here it goes.

                  W/Stock BIOS - 1.06:

                  GPU VBIOS for Razer Blade 15 Advanced (RZ209-033)
                  by shybear
                  hi,

                  when I power ON this laptop it give me this red warning message:

                  "the detected discrete gpu VBIOS is not meant for this system, press Enter to continue"

                  Machine start and works properly. I was also able to update machine BIOS to last version 1.06.

                  I attach here a copy of the orginal VBIOS stored on GPU flash memory chip.

                  Thanks so much for help....

                  Razer Blade 15 Advanced (RZ209-033) graphic card issue
                  by shybear
                  hi,
                  this laptop works but temperature rise too much. I dismounted mb and cleaned well. There was a lot of dust inside.
                  I think that there is a graphic chipset issue because when I power the machine I get this error:
                  "the detected discrete gpu VBIOS is not meant for this system"
                  This make me think that maybe the gpu VBIOS has to be re programmed.
                  BTW someone already worked on this mainboard. Near graphic board there is Winbond flash memory that I think its stored the VBIOS.
                  I attach some pictures and one of message error I get when I power on the ...
