Hi @Mogaka 

Welcome to the HP Forum.

I would not worry if the PC is okay.

I have a solid blue power on LED on my custom built PC. I also have a flashing red HDD/SSD activity LED.

HP has produced and brought to market more than a thousand different models of notebooks and desktop PCs over the years.

It is difficult to help you if we don't know which specific model you own..

Method #1: If the notebook will boot into Windows, you can retrieve your Product Number by pressing Fn + Esc key.

Method #2: Press the power button and immediately tap the F10 key to invoke the BIOS. In the Main section, you will find the Product number or Product ID. Post that in your next reply in your thread.

Method #3: Press the power button and immediately tap the F2 key.

Method #4: If powering on is not an option, take a look at the bottom of the laptop for the label with the product name and product number. For a desktop look at the rear for the label.

If your laptop/desktop PC has HP Hardware Diagnostics UEFI version 10.3.0.0, there is a System Information section that also has the Product ID.
We need that information, along with the installed Operating System information to help you.

I do remember older HP desktops, that  had a  power button would turn from white to blue when powered on.

That was normal.
