Checking the Power Settings

One of the potential causes for screen dimming when you connect your electrical cord to your HP laptop is the power settings. Your laptop’s power settings dictate how the system behaves when it is plugged in or running on battery power. Here’s how you can check and adjust the power settings to resolve the screen dimming issue:

1. Access Power Options: Open the Control Panel or navigate to the Settings app on your laptop. Look for the Power Options or Power & Sleep settings.
2. Select Power Plan: In the power settings, you will find a list of available power plans such as Balanced, Power Saver, or High Performance. Select the power plan that is currently active.
3. Change Plan Settings: Once you’ve selected the power plan, look for the “Change plan settings” option. It will allow you to modify the settings of your selected power plan.
4. Adjust Display Brightness: Within the power plan settings, you will find options to adjust the display brightness when your laptop is plugged in or running on battery power. Make sure that the brightness level is set to your desired preference when the charger is connected.
5. Prevent Automatic Brightness Changes: Some power plans have a feature called “Adaptive Brightness” that automatically adjusts the screen brightness based on ambient light conditions. If enabled, this feature can cause unwanted dimming. Disable it by going to the advanced power settings and locating the “Display” or “Screen” settings.
6. Save Changes: Once you’ve made the necessary adjustments to the power plan settings, save the changes and exit the power options menu.

By checking and modifying the power settings on your HP laptop, you can prevent any automatic adjustments to the screen brightness when you connect your electrical cord. This will ensure a consistent and optimal brightness level that suits your needs.

If the screen dimming issue persists even after adjusting the power settings, try exploring other potential causes such as adjusting the screen brightness directly, updating the graphics drivers, or resolving any hardware issues. By methodically troubleshooting each possibility, you can resolve the screen dimming problem and enjoy a bright and vibrant display on your HP laptop.

Check the power settings on your laptop to ensure that the screen brightness is not set to automatically dim when the laptop is plugged in. Adjust the settings to maintain the desired brightness level.

Adjusting Screen Brightness

If your HP laptop’s screen dims when you plug your electrical cord, one possible cause is that the screen brightness level may be set too low. Adjusting the screen brightness is a simple yet effective solution to restore the optimal brightness on your laptop’s display. Follow these steps to adjust the screen brightness:

1. Look for the Brightness Controls: Most HP laptops have dedicated function keys or buttons for controlling screen brightness. These keys are typically located on the top row of the keyboard, marked with an icon resembling a sun or light bulb. Press the function key (usually labeled with “Fn”) along with the corresponding brightness control key to adjust the brightness.
2. Use the On-Screen Display: Some HP laptops feature an on-screen display that allows you to quickly change the screen brightness. Look for a small icon resembling a sun or a light bulb on one of the corners of your screen. Click on it, and a slider will appear that allows you to adjust the brightness level.
3. Access the System Settings: If the above methods don’t work, you can adjust the screen brightness through the system settings. Open the Control Panel or go to the Settings app on your laptop. Look for the “Display” or “Brightness” settings. Here, you will find a slider that allows you to increase or decrease the screen brightness.
4. Find the Perfect Brightness Level: Adjust the brightness level to your desired preference. You may need to try different brightness levels in different lighting environments to find the perfect balance between visibility and comfort.
5. Save the Changes: Once you’re satisfied with the new brightness setting, save the changes and exit the settings menu. Your laptop will remember this setting for future use.

By adjusting the screen brightness, you can counteract the dimming effect that may occur when you connect your electrical cord to your HP laptop. This will allow you to work, browse, or enjoy multimedia content with optimal visibility and eye comfort.

If adjusting the screen brightness does not resolve the issue, consider exploring other potential causes, such as checking the power settings, updating the graphics drivers, or addressing any hardware problems. By troubleshooting each possibility, you can pinpoint and rectify the issue, ensuring a bright and vibrant display on your HP laptop.
