Black-blank screen

[OmarMahmoudabo]

So today I was trying to boot up my laptop but all I get is black screen. Can't even get to bios.

Camera sensors actually work and I think I loaned windows but like I said I can't be sure because its just black screen.

Tried the winkey+b to update the bios but waited 40s and nothing happend so I left it for hours still nothing.

Just black screen.any fixes?

Why would you think a forced BIOS update would have anything to do with fixing this?  BIOS updates are for security features and new hardware.

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number:

Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options
--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
https://www.service-center-locator.com/hp-hewlett-packard/hp-hewlett-packard-service-center.htm

If that link does not get you a useful page, then use the main HP link:
http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

If you can't get assistance from HP, then you will have to seek out a local laptop service facility to have them examine it for you.

Good Luck

 thing is. Its not black which means the screen is not connected due a major hardware failure.

As you can see the light. Also the camera sensors was working means I already loaded to the login screen.

Any other fixes before try to go to a local service help

My reply said when the screen is "blank" -- and it certainly looks blank in your screenshot.

So, yeah, you would need to have it looked at to determine the underlying issue if you are unable to run diagnostics yourself.
