HP Pavillion Power (15-CB004NA) not botting up

[garethgina]

I have an HP Pavillion Power that refuses to boot up - the power light comes on under the on/off button - and the disks seem to make a noise - but the screen remains black - with absolutely nothing showing. 

Tried holding the power button down for 15 seconds (as reccomended in some forums) - nothing. 

This seems to be a latop where yu CANNOT (easily) take the battery out - certainly no obvious quick release. 

Any thoughts out there?

Hi @garethgina,

Did it happen after a recent software update or Windows update?

Have you tried to connect this laptop to an external monitor and check if it works?

In the meantime, let's try these steps here: 

Let's start off by performing a Hard reset on the notebook: 

Before power resetting your computer, do the following:

1. Disconnect or remove all peripheral devices. Start up the laptop and test the computer by itself, and then reconnect one peripheral device at a time.

2. Turn over the computer and look for a battery compartment door.

   • If there is a battery compartment, use the steps in Reset a laptop with a removable battery.

   • If there is no battery compartment, use the steps in Reset a laptop with a sealed or non-removable battery.

Next thing, I would suggest here is to follow the steps suggested in the support document for - HP Notebook PCs - Computer Starts but Screen Remains Blank

You may also go through the steps suggested in the support document for - HP Notebook PCs - Computer Does Not Start (Windows 10)

Let me know how it goes!
