Troubleshooting Screen Issues for HP Laptop

If you are experiencing screen issues on your HP laptop, there are several troubleshooting steps you can take to resolve the problem. In this article, we will discuss various common screen issues and the steps to address them.

Blurry, Fuzzy, or Stretched Image on Screen

2. Adjust the display resolution.
3. Update the graphics driver software

No Image on the Screen or the Screen is Blank

If the display has flickering, lines, or distorted colors, it could indicate a problem with the graphics card or the display hardware.

Touchscreen Issues

1. Calibrate the screen for pen and touch input.
2. Perform a touch screen diagnostic test in HP Hardware Diagnostics.
3. Update the BIOS and graphics driver

Hardware Diagnostics

Use the HP PC Hardware Diagnostics UEFI tests to detect problems with the touch screen hardware. Connect the AC adapter to the computer, press the power button for at least five seconds to turn off the computer, press and hold the power button for approximately 15 seconds, drain the capacitors, reconnect the AC adapter, leave peripheral devices disconnected, turn on the computer, and update the BIOS and graphics driver.

How to Hard Reset

If none of the previous steps worked, perform a hard reset. After resetting the computer, wait for the computer to start, and then tap the screen to see if it responds.

Conclusion

Troubleshooting screen issues on an HP laptop can be a complex task, but by following the steps outlined above, you can resolve many common screen problems. If you continue to experience issues after trying these steps, consider contacting HP Customer Support for further assistance.

How to turn on a laptop

To turn on a laptop, locate the power button, which is usually located slightly behind the keyboard and marked with the universal symbol for ‘power on‘, a circle with a line going halfway through it.
Press the power button to turn on the laptop and wait for it to boot up. If the laptop does not have a power button or the power button is not working, some laptops can be turned on by pressing a key on the keyboard. 
Alternatively, it is possible to turn on a laptop without a power button by wiring a remote power button or using a smart plug.

How to turn off a laptop

To turn off a laptop, you can use the following methods:

1. Using the Keyboard:
   • For Windows laptops, you can press Alt + F4 to bring up the shutdown dialog and then select the shutdown option.
   • Another option is to press Ctrl + Alt + Del and then select the shutdown, restart, or sleep option.
   • On a Mac laptop, you can press the command, control, option, and power buttons together to initiate the shutdown process.
2. Using the Power Button:
   • If the above methods are not available, you can simply press and hold the power button until the screen goes dark to force the laptop to shut down.
3. Alternative Methods:
   • Some modern laptops can be turned on by pressing a key on the keyboard, which can also be used to turn off the laptop if configured.

If the laptop’s power button is not working, alternative methods such as using a smart plug or wiring a remote power button can be considered.
