HP Omen 17 not booting after bios update

HP Recommended
Omen 17-an009ur
Microsoft Windows 10 (64-bit)

Yesterday I received a request from Windows 10 to reboot to complete a system update of my HP Omen 17 laptop, I did it.
The HP bios updater screen appeared, I agreed to update bios.
After flashing and verifying the HP bios updater requested to reboot, I did it.
After that and subsequent reboots my laptop showing a black screen and CapsLock led blinking (5 long and 3 short blinks) and nothing more.
I tried to reboot with holding Win+B keys but with same result.
Can you help me please with this problem?

I reviewed your post and I understand that the computer is not booting to Windows after the BIOS update.


Don’t worry, I assure you I will try my best to get this sorted.


If the caps light is blinking 5 long and 3 short blinks mean a system board failure. However,

I recommend you follow the steps in the below article and roll back the BIOS to the previous version and check if it helps.


If you continue facing the issue, I recommend you contact support and check the available service options for your computer.


Here is how you can get in touch with support.


1)Click on this link –

2)Select the product type.

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

4)Select the country from the drop-down.

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


Let me know how it goes and you have a great day!
