A730m graphics card not working

[georgelee]

I bought the Intel NUC x15. The model is: LAPAC71H, it is equipped with Intel arc a730m graphics card and supported by Intel iris XE graphics card. It used to work normally until I replaced the SSD, and then the touchpad failed to work. The specific performance was that the touchpad could move the mouse, but could not click OK, and the mouse had to be used to operate the system. Then I reinstalled the system, which is the win11 23H2 version. When I reinstalled the driver as required, I found that my computer was running with the XE graphics card. In the device manager, the A730m graphics card was missing. Since then, I've tried various methods, including updating drivers, updating BIOS firmware, and flashing previously backed up drivers. Reinstalling doesn't completely solve the problem. Now my a730m graphics card is hidden, clicking properties says this device is not starting, code 45. On the command center under the GPU tab, it only shows the Intel Iris XE graphics card, and now when I go into task manager GPU1 is no longer there , when I go into Games in Settings and click on any game, the only options now are Power Save: Intel Iris XE Graphics and Better Performance: Intel Iris XE Graphics. The previous Intel Arc A730M performed better, but not anymore. I asked for help. Can anyone help me?

This seems to be a hardware compatibility issue to me. Have you tried reinstalling the original SSD to see if that resolves the issue?

LAPAC71H - Product Specification

I have a GEN4 ssd installed in the PCI GEN4 port and a PCIgen3 ssd installed in the PCI GEN3 port, so there shouldn't be a compatibility issue, but based on your suggestion, I will now swap the SSDs in the two sockets to verify the compatibility issue.

According to your suggestion, I changed the hard disk location. In order to ensure that the compatibility problem is eliminated, I replaced the original GEN4 hard disk location with the original ssd that supports GEN4 performance, but this still does not solve the problem. Even in the device manager interface, I can't find the A730m device. Is there a better way to solve this problem?

"Code 45" in Windows Device Manager indicates that a device is not connected. This is usually a hardware-level problem. I thought that maybe the new SSD was using different resources and was blocking the A730M. But if the original hardware state with the original SSD does not solve the problem, you may have to assume that the device has been damaged.

Everything else is already done:

• Reset BIOS to default
• Update/reinstall the device driver

• Reset BIOS to default
• Update/reinstall the device driver
• I have tried these two operations about 10 times, and I can't solve the problem at all. I have also seen other people in the forum have this situation. His solution is to create a repair claim document. I think I should do the same. If so, how should I create this document?Who should I contact?

You can request a Return Merchandise Authorization (RMA) from where you purchased the device.

Since I am currently abroad and I will arrive in Azerbaijan in September, I can only come here for help, can you help me?

[MUC]

No, I'm sorry. As a private person, I can only offer help with technical questions. In my personal opinion, your device is somehow defective.

Thank you very much for your reply. I have created a technical support plan on Intel's official website. I am waiting for their reply. Thank you again for your help and have a nice day!
