@Ashu777 Welcome to HP Forums Community!

If the BIOS on your computer becomes corrupted, the computer fails to boot to Windows. The BIOS can be corrupted during normal operation, through environmental conditions (such as a power surge or outage), from a failed BIOS upgrade or damage from a virus. If the BIOS is corrupted, the system automatically attempts to restore the BIOS from a hidden partition when the computer is restarted. 

If that doesn't happen, you may need to manually recover the BIOS and here's how to do it:

1. Turn off the computer, and then connect the power cord.

2. Press and hold the Windows key and the B key at the same time, and then press and hold the Power button for 2 to 3 seconds.
    

   

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

   • If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next section to Recover the BIOS using a USB recovery drive.

   • If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for only 2 to 3 seconds.

   • If a BIOS recovery message repeatedly displays, continue to the next section to Recover the BIOS using a USB recovery drive.

   • If a message that the computer improperly shut down or a boot problem is detected displays, follow the on-screen instructions to resolve the error.

   • If Windows starts, update to the latest BIOS version. Go to HP Notebook PCs - Updating the BIOS for more information.

   The HP BIOS Update screen displays and the recovery begins automatically.

   

If this recovery method fails, use another working computer to create a BIOS recovery flash drive to install the latest BIOS file.

@Ashu777 How do you know it works, what changed? also, could you check with an alternate monitor? does that have a display?

here's how to check with an external monitor:

1. Connect an external monitor to the notebook. For instructions, see Connecting a Monitor, Projector, or TV (Windows 10, 8 ).

2. If the computer screen does not display on the external monitor, press F4 (or the key with this symbol ) until the screen image displays.

3. If an image displays on the external monitor, there might be a graphics driver conflict with the notebook LCD display. With the external monitor connected, go to HP Customer Support - Software and Driver Downloads. Download and install the latest graphics and chipset drivers for your specific computer.

I did as you said but it doesn't work .I called the service center the Engineer came after 10 days and he said the motherboard is damaged because of BIOS update.

[Riddle_Decipher]

@Ashu777 If that didn't work, the engineer could be right as it does seem like a motherboard failure, I suggest you talk to HP support and discuss your options,

follow the below steps to get started:

1) Click on this link - www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
