Thank you for posting on the HP Support Community.

• Did this happen after a recent window or software update?
• Have you tried connecting the computer to an external monitor to test the display?

While you respond to that, let's try these steps: 

Use these steps even if you cannot see anything on the monitor:

1. Turn off the computer.

2. Connect the notebook to a power source using the power adapter.

3. Press and hold the Windows key  and the B key at the same time while the computer is off.

4. While still pressing both keys, hold down the Power button for one second, and then release the Power button and the keys.

   The power LED light remains on, and the screen remains blank for about 40 seconds. You might hear beeping sounds. Afterwards, an HP BIOS Update screen displays and the BIOS update begins.

If recovering the BIOS did not resolve the blank screen problem, continue to the next step. "Reseating the memory modules"

Use the following steps to remove and reseat the memory modules:

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

    CAUTION: Electrostatic discharge (ESD) can damage electronic components. Before beginning any procedure, touch a grounded metal object to discharge static electricity.

2. Remove the cover to access the memory.

   Your computer might look different than the computer in the graphic.

   NOTE: Some computers might not have a cover that provides access to the memory. Have the computer serviced if you cannot access the memory.

   

   1. Retention screws (2)

   2. Direction to remove compartment cover

3. Remove memory modules in the computer.

   

4. Reinsert all memory modules.

   1. Notch alignment

   2. Direction to insert the module

   3. Direction to seat module

5. Replace the cover, battery, and power cord.

6. Turn on the computer.

7. Perform any tests to verify that the computer can start up and run in the Windows operating system.
