[MikeAlani]

Hi, My NVME PCIe was workin as PCIe 3 X4 with reading speed up 2800M, however after bios update my PCIE changed to 1 x 4 and speed is about 500M. Please I need to rollback the bios urgently as I did'nt pay all that money to buy 970 Samsung to get 500M!!

Welcome to HP Forums,  

This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that you are wanting to roll back bios update,

Let's try this: Recover the last working BIOS version

1. Turn off the computer, and then connect the power cord.

2. Press and hold the Windows key  and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

   The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.

   

   • If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.

   • If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.

   • If a BIOS recovery message repeatedly displays, continue to the next step to install an updated BIOS version.

   • If a message that the computer improperly shut down or a boot problem is detected displays, follow the on-screen instructions to resolve the error.

   • If Windows starts, update to the latest BIOS version. Go to HP Notebook PCs - Updating the BIOS.
