black screen problem

Problem: black screen

Comments: I hear and see the fan is running. I have hooked up external monitor and it is also a black screen. I have completed several hard resets but no results. 

What are the possible problems? What are the fixes?

Thanks for any replies,

Hi

When do you usually get the "Black screen"? After logging in? Does it came with a white cursor?

If YES try these steps:

Press Ctrl+Shift+ESC to launch Task Manager or Ctrl+Alt+Del

Click File

Click Run

Type msconfig. System Configuration Utility will show up

Click Service

Uncheck App Readiness then click apply

Restart the computer

After the restart download the softpaq to permanently fix black screen

For HP.com , the softpaq was released as “HP Image Enhancement for System Logon” and could be found under the “Software-Solutions” category.  Below is the reference link to download SP81965 for Kerberos 1.1:

https://support.hp.com/us-en/drivers/selfservice/hp-spectre-15-bl100-x360-convertible-pc/16779592

Or you could open HP Support Assistant app and look for updates and look for “HP Image Enhancement for System Logon” and install it.

After installing the Softpaq. Go back to msconfig then put a check mark to App Readiness App then click apply and okay.

When I start the laptop, there is not a cursor or anything shown on the screen. The caps  lock light blinks several times then it also stops.

Hi,

Thank you for further explaining whats going on. Have you tried running diagnostics? If not then boot your computer to start menu by shutting down the computer completely.

Press and hold down ESC then tap power button once

A Pop up window should appear (Start Menu)

Select F2 using arrow keys or F2 button

Run System test > Extensive Test > Run Once

Normally extensive test will run for 3-4 hours. Make sure the charger is connected during diagnostics

Please keep us posted.

Regards,

ichi
