Laptop screens are prone to several display problems.
Laptop computers have LCD displays that are sensitive to many things. LCD displays have faults that sometimes produce a flickering screen, lines, dots or a faint display. These screens are sensitive to magnetic fields or electronic items near the computer. Speakers, cell phones, lights and other electrical items are examples. Your display also could be flickering due to software issues such as the video drivers or hardware issues relating to a faulty inverter or the LCD screen itself needing to be replaced. Trace the cause of your problem to come to a resolution.
Instructions
1. Turn off the computer. Disconnect all external devices. Turn the computer over (bottom facing up). Take out the battery and reseat it. Turn on the computer.
2. Reset your resolution and refresh rate by right-clicking the desktop and selecting Screen Resolution. The Change the Appearance of Your Display dialogue box appears. From the Resolution drop-down list, select the recommended resolution of your display. If you don't know the recommended resolution, refer to the product manual. Click the Advanced Settings link in the lower right. The graphic card dialogue box appears. Click the Monitor tab. From the Screen Refresh Rate drop-down list, select 60 Hertz. Click OK.
3. Check your computer's surroundings. Move away speakers, fluorescent lights, fans, cell phones, radios and other electrical devices that can cause flickering. Temporarily move electrical items away from the computer to determine whether they are producing this issue.
If the flicker stops, put back one item at a time to determine what is causing the problem.
4. Connect an external monitor to your laptop computer to determine whether that screen also flickers. If there is no flicker, then the problem is strictly with the laptop, indicating a possible hardware failure. Contact the manufacturer for a replacement LCD.
If the flicker continues, proceed to the next step.
5. Reinstall the video driver. To do so, log in to an administrator account. Then navigate to the Start menu and right-click Computer. Select Properties from the drop-down list. From the left pane of the dialogue box, select Device Manager. From the Device Manager, double-click Display Adapters. Double-click on your graphics card, select the Driver tab and select Uninstall. Then reboot your computer. Device Manager reinstalls the video driver. Verify whether your display's flickering has stopped. If not, proceed to the next step.
6. Navigate to the manufacturer's website. Download and install the newest video driver and BIOS for the computer. Restart the computer after the drivers are installed. Continue to the next step if there is still flickering.
7. Carefully open up your display screen all the way. If the flicker stops by opening it a certain distance, the display inverter is faulty. If the flicker still exists, the LCD screen should be replaced.
8. Contact the manufacturer of the computer for more information and a possible replacement inverter. This will depend on the manufacturer and the computer itself.
