The system BIOS recovery failed. Unable to open BIOS Signature File

[KerDew]

Hello

One week ago i turned on my laptop (HP ENVY x360 - 15-u170nb(ENERGY STAR)) and it didnt want to boot, instead the caps lock blinks twice then 3-5 seconds no blink.

I searched the forums and i think there might be something with my BIOS, so i downloaded the latest BIOS firmware (Jun 26, 2018; sp88691.exe) and extracted it on to a USB to create a BIOS recovery USB.

After I insert the USB, the laptop did start up to recover / update the BIOS, but then it says:  The system BIOS recovery failed,  Unable to open BIOS Signature File. Tried to restart over and over again, but didn't work.

Does anyone have a solution please?

Kind regards

Kerim

@KerDew You may want to try the BIOS recovery using the steps mentioned in this link: Click here 

meanwhile, here's what you need to know: 

3.5 (blink) represents: 

The CPU is not detected and that's a hardware malfunction that will need a repair or replacement of parts.

Also, go through this link and tell me if that's 3 short blinks followed by 5 short blinks, or is there any difference?

Let me know how that pans out,

Hi 

I allready tried the windows + B / V press together with power button, but the beep doesnt sound.

The blinking pattern is the next one: * - * ---

* = blink

- = pause

hope you have a solution.

@KerDew I'm afraid that would confirm a hardware malfunction, as the BIOS recovery using the link I shared was the only step that could have worked since it hasn't I suggest you talk to HP support and discuss your options:

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, is yes? please send me a private message with the region you are contacting us from,
