HP Envy x360 15-cn0xxx - black screen after bios update

[Zombi_2019]

Hi to all,

I  installed  HP Support Assistant on my HP and I had the bad idea of ​​making the latest updates (including bios).

After restart and bios update followed "black screen".

Tried with "windows"+B+power button for 3 seconds + recovery stick on usb but without succes.

Original bios version : B.01 and vendor : Insyde.

You have some solutions for my problem?

Thanks for all!

This looks like a possible hardware failure. I would recommend you contact our HP support team for further assistance.

Select the product type.

Enter the serial number of your device or select let HP detect your product option.

Select the country from the drop-down.

You should see the HP phone support number or Chat option listed.

Thanks for your support but I've already done that without any succes.

The problem is: back cover is broken and I don't have the serial number.

But I have a picture with first page of original bios (when laptop working).It is ok to post it here?

I post the picture with mainboard.

So, I wanted the *.bin file for 25q128 flash memory.

Thanks for all,

@Zombi_2019,

The information which are you looking can be accessed only by an Authorized service tech.

The best option possible would be to send in the unit for repair and in the service center, and I'm sure they should be able to go ahead and address your issue.

I hope this information helps. Let me know if you need any further assistance!

Take care now and do have a fabulous week ahead. 🙂

Hi,

In the original bios the "system board id" is: 8484 but on recovery stick created by bios update the of bin is: 08483.bin

I don't know if this is the problem.

Now I try to find the 08484.bin.

Thanks.
