What is the ‘black screen of death?’
The ‘black screen of death’ refers to a common issue where the screen of an HP Elitebook 8460p laptop suddenly goes black. This can be caused by a variety of factors, including hardware or software issues.
To fix this problem, try the following steps:
1. Check the power supply: Ensure that your laptop is properly connected to a power source and that the battery is charged. A low battery or power supply issue can cause the screen to go black.
2. Restart your laptop: Press and hold the power button until the laptop shuts down. Then, press the power button again to turn it back on. This can help resolve temporary software glitches.
3. Boot into safe mode: Restart your laptop and press the F8 key repeatedly before the Windows logo appears. This will bring up the Advanced Boot Options menu. Select “Safe Mode” and see if the black screen issue persists. If it doesn’t, it may be caused by a problematic driver or software.
4. Update graphics drivers: Outdated or incompatible graphics drivers can cause display issues. Visit the HP website or use the Device Manager to download and install the latest drivers for your graphics card.
5. Perform a system restore: If the black screen issue started recently, you can try restoring your laptop to a previous working state. Go to the Control Panel, search for “Recovery,” and select “System Restore.” Follow the on-screen instructions to choose a restore point and revert your system settings.
Connection issues with the monitor
First, check the cables. Make sure the VGA or HDMI cable is securely connected to both the monitor and the computer. If the connection seems loose, try unplugging and re-plugging the cable.
If the cables are secure and the screen is still black, try adjusting the brightness. Look for the function key on your keyboard that has a symbol resembling a sun or lightbulb. Hold down the “Fn” key and press the brightness function key to increase brightness.
If adjusting the brightness doesn’t work, try restarting your computer. Sometimes, a simple reboot can fix connection issues.
If none of these steps resolve the problem, it may be a driver issue. Visit the manufacturer’s website and download the latest driver for your monitor. Install the driver and restart your computer.
If all else fails, try a factory reset. This will restore your computer’s settings to their original state. However, be aware that a factory reset will remove all personal data and installed applications, so be sure to back up your files before proceeding.
Display device/adapter problems
If your HP Elitebook 8460p screen goes black, follow these steps to fix the issue:
1. Check the power source and cables: Make sure the laptop is connected to a power source and the power cable is securely plugged in. Also, check the video cable connection between the laptop and the display device/adapter.
2. Adjust display settings: Press the Windows key + P to open the display settings. Select “Extend” or “Duplicate” to ensure the display is being properly recognized.
3. Restart the computer: Sometimes, a simple restart can resolve display issues. Press the power button to turn off the laptop, wait a few seconds, and then turn it back on.
4. Update display drivers: Outdated or incompatible display drivers can cause black screen problems. Visit the HP support website or use Windows Update to download and install the latest drivers for your graphics card.
5. Perform a hard reset: Shut down the laptop, disconnect all external devices, and remove the battery. Press and hold the power button for 15 seconds, then reinsert the battery and turn on the laptop.
6. Run hardware diagnostics: HP Elitebook laptops have built-in diagnostic tools that can help identify hardware issues. Restart the laptop and press F2 repeatedly to access the diagnostics menu. Run the tests to check for any display-related problems.
7. Contact HP support: If the issue persists, it may be necessary to contact HP support for further assistance. They can provide personalized troubleshooting steps or arrange for a repair if needed.
Faulty system update or software/app installation
If your HP Elitebook 8460p screen goes black after a faulty system update or software/app installation, there are a few steps you can take to fix the issue.
First, try performing a hard reset to refresh the system. To do this, disconnect all peripherals and remove the power cable. Press and hold the power button for around 15 seconds, then release it. Reconnect the power cable and turn on the laptop.
If the screen is still black, try connecting an external monitor using a VGA or HDMI cable. If you can see the display on the external monitor, it means there might be an issue with your laptop’s LCD screen. In this case, you can try updating or reinstalling the graphics driver through the Device Manager.
If the external monitor also displays a black screen, try booting the laptop in safe mode by pressing the F8 key repeatedly during startup. In safe mode, you can troubleshoot any software conflicts or driver issues that may be causing the problem.
