Laptop has abruptly stopped working after applying an update

[Spinto46]

So I was watching netflix and I got the warning that I had ~5 minutes to shut down the computer or it would shut down itself so that it could update itself. I got done closing things and shut it down by hitting the power button and holding it down.  Next I turned the laptop back on and it started to update so I zoned out of it and watched something on my phone. While doing so I noticed some type of an error updating message and did not touch is because last time this happened it just rebooted without the update. However instead it turned itself off and did not turn back on. I tried hitting the power buitton to turn it back on and that did not work. I also tried the suggestions I found on this support website such as taking out the battery pack and unplugging the AC adapter for the power source.

I grasp you were watching Netflix when you got a notice that you had 5 minutes to shutdown the computer or it would do a restart.  You closed your programs and powered the notebook off using the power button. On the restart, the update started to install. While installing the update you received an error message but did not pay attention as you assume it would revert the changes and restart again.  It powered off but did not restart.   You have tried a hard reset as suggested in another post in the HP Forum but there was no change.

  Can you start in safe mode?

When you try to start the notebook exactly what happens?  Do you get a blank/black screen? Do you see any blinking lights or hear any beeps?

I await your reply.

I am not sure how to start in safe mode as when ever I try to power the computer up no lights come on and the screen stays black, there is no noise produced by the machine and I am very unsure as there has never been any exposure to something like water that would have caused this.

Hi @Spinto46,

Thank you for your reply.

I grasp that when you try to power on the notebook, you do not hear any noises such as the hard drive spinning up or see any lights.  Here is a link to help you determine it the AC adapter is functioning:

Hi @Spinto46,

Thank you for the update.

As you have determined that the adapter is working, it could be the power button board in the notebook.  The notebook will require a repair.  Please contact HP Support for service options. They would provide you with an estimate before completing any repairs.

Please contact HP support at Contact HP Support

If  you are not under warranty, a local repair shop should be able to provide you with an estimate also.

If  you wish  to consider replacing it yourself to see it that is the issue, here is a link to the:

Please note chapter 4, page 52 for the replacement part number and removal and replacement instructions.
