How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

Plug the USB cable into the printer. Plug the other end of the USB cable into the computer. You might need to configure certain network parameters on the product. You can configure these parameters from the control panel, the embedded Web server, or for most networks, from the HP Web Jetadmin software.
One of the common causes is the hardware faulty, such as the loose connection of your GPU, or the bad cables or port can also result in the screen not working. Apart from the hardware issue, your laptop screen can be black because of the software problems, such as the virus or the software corruption.
If your HP laptop screen still goes black, you need to restart the explorer.exe process. This will help clear any cache that might be intervening with the internal features of the laptop and causing the issue. Press the Ctrl+Shift+Esc keys to open the Task Manager.
Requirements: Operating System – Windows 7, Windows 8, Windows 8.1, Windows 10.
Check the USB cable for damage and recommended length, and then restart your printer and computer. Turn off the printer and the computer. Disconnect the USB cable from the computer and printer, and then inspect the cable. If the cable is damaged or longer than 3 m (9 ft 10 in), replace it.
On the printer display home screen, select the “set up” button (it looks like a gear). 2. Select “settings” > “device settings” > “reset settings” > “reset all” > “OK” and then “Yes.”
The primary reason you get no display on your PC could be damaged or loosely connected cables. Other reasons may include incorrect display configuration, faulty or problematic GPU or RAM, incorrect BIOS configuration, faulty peripheral devices, or damaged PSU (Power Supply Unit).
This is usually the result of faulty Windows updates, but corrupt or missing system files can also play a role. Applications and drivers. An outdated or malfunctioning application or driver can lead to black screen errors.
The screen`s LCD connectors may be loose. There is a critical system error. You may have installed incompatible apps. The phone may have been overcharging for a long period of time.
A Print Screen button not working the way it should is often the result of physical damage to the button itself or a keyboard that needs a firmware update. An out-of-date Windows operating system can also cause Print Screen to malfunction, as can a lack of system storage and free memory.
Depending on your hardware, you may use the Windows Logo Key + PrtScn button as a shortcut for print screen. If your device does not have the PrtScn button, you may use Fn + Windows logo key + Space Bar to take a screenshot, which can then be printed.
