Acer Chromebook Black Screen

If the battery is dead and your device is not receiving power, it will not display any content on the screen. This could indicate a problem with your device's charging adapter. Verify the following to ensure your device receives power from the charger.

• The outlet you're plugging into is outputting power. Fuses can go out, and outlets can suddenly stop providing power. Check that another appliance can pull sufficient power from the outlet, or move your charger to an outlet you know works.
• Listen for the sound of your device's cooling fans. If your Chromebook has an active cooling system, you should be able to hear the fans powering on when you start up the device.
• Check if your device's status LED illuminates. The Status LED can determine whether the unit receives sufficient power for passive cooling systems. Typically, these are located on the sides of the device.

If you cannot hear the device's cooling system and the Status LED does not illuminate, try plugging in your device using a known undamaged charging adapter. The LED indicator light should turn on immediately after connecting the Chromebook to power. If the screen only turns on when the device is connected to power, there is likely an issue with the battery. For further assistance, refer to the appropriate guide specific to your Chromebook model.

When using an external display with your Chromebook, it is typical for the operating system to keep trying to communicate with the external display even after it has been disconnected. This can result in display-related issues or errors.

1. Connect your Chromebook to an external monitor or TV using the available outputs. This will allow you to test the functionality of ChromeOS on the external display.
2. Switch from the main display to the external display. To switch the show from an external display back to the main screen, press the Ctrl + Maximize (F4 or F5) keys.

If you have verified that ChromeOS is working correctly with the external display but fails to switch back to the main screen, the primary display likely is defective or broken.

To address any potential software issues causing your device to have trouble detecting the internal display, you can attempt to restore ChromeOS using a recovery disk. The instructions for creating a ChromeOS recovery disk are provided below, and an in-depth guide can be found here. An empty USB drive with at least 8 GB of storage is required.

1. Install the Chromebook Recovery Utility Extension: Open Google Chrome and install the Chromebook Recovery Utility Extension from the Chrome Web Store. Click on the extension and follow the on-screen instructions.
2. Prepare Chromebook for Recovery: Turn off your Acer Chromebook and ensure it's connected to a power source. Press the Esc + Refresh (F3) keys simultaneously, then press the Power button. Release the Power button when the Chromebook starts, but continue holding Esc + Refresh until you see a screen prompting you to insert the recovery disk.
3. Recover ChromeOS: Insert the previously created recovery disk into your Chromebook and follow the on-screen instructions to initiate the ChromeOS recovery process. This will reinstall the operating system and can resolve software-related problems that may be causing the black screen issue.
4. Follow System Setup: After completing ChromeOS recovery, follow the on-screen instructions to set up your Acer Chromebook as you would during the initial setup. Check if the black screen issue is resolved.

If the issue persists after restoring ChromeOS, proceed to the more in-depth troubleshooting steps below.

If your Chromebook is not powering on or showing signs of life, the issue may be related to the battery. Follow these steps to troubleshoot battery-related problems.

1. Check Battery Level: Connect your Chromebook to the charger and allow it to charge for at least 15 minutes. After that, check if the charging indicator light confirms that the device is charging.
2. Reset the Battery: On certain Acer Chromebooks, you may find a small pinhole reset button on the bottom or side of the device. To reset the battery, insert a paperclip or similar tool into the pinhole and press gently. Afterward, attempt to power on the Chromebook and check if the issue is resolved.
3. Replace the Battery: If resetting the Chromebook hasn't worked, and you aren't seeing any signs of life from your device, it's probably not turning on due to a faulty battery component. Use the appropriate guide for your specific Chromebook to restore life to your device.

If the Chromebook still does not power on, proceed to the next section.

If your Acer Chromebook works with an external display but not with the attached display, it suggests damage to the screen. To check if the display might be faulty, follow these steps.

1. Power off your Chromebook. Be sure to remove any peripherals or power sources.
2. Carefully inspect the internal display for physical damage. This includes any significant or small cracks or any liquid damage. Checking from different angles can help spot hairline cracks as they catch in the light.

If the screen is damaged, the best solution is to replace it. Use the appropriate guide for your specific Chromebook. If you cannot find any damage to your display, then chances are the display cable might be experiencing complications. Read on.

In most Acer Chromebooks, the internal display is located beneath the display bezel. A cable sends signals to the LCD panel from the logic board. If this cable is disconnected or damaged, the display may not work.

• Ensure that the internal display is securely connected to the motherboard via the display cable. This will involve some dismantling—check out a relevant Chromebook guide to see how to get inside your Chromebook. Ensure the display cable is securely plugged into the LCD panel and motherboard. If the cable appears loose, reconnect it carefully. After reconnection, test the display to see if the content appears correctly on the LCD panel.
• Perform a visual inspection of the display cable. If no visible damage is apparent, thoroughly examine the display cable connections. Check both the end of the display and the point where the display cable connects to the motherboard. Look for any signs of damage, such as burns or indications of liquid damage. If any damage is found, try to source a new display cable and replace it.

If you don't find any issues during the display and display cable inspection, proceed to the final section for further troubleshooting.

Suppose your Acer Chromebook displays a black screen even after following the troubleshooting steps mentioned earlier. In that case, there is a high likelihood of a problem with the motherboard or the surrounding components.

1. Ensure that your device's CPU is adequately cooled. Specific Acer Chromebook models, such as the C712 Series, have encountered problems with cooling fan failure caused by the daughterboard's ribbon cable becoming disconnected from the motherboard. If you have recently reinstalled your heatsink, double-check that it is correctly attached to your CPU and that the CPU has the appropriate amount of thermal paste applied. Proper cooling is essential to prevent overheating and ensure optimal performance.
2. Remove any accumulated dust or debris from the internal components of your device. It is crucial to maintain proper airflow within your device. Dust or debris can hinder the cooling process, potentially causing issues with the operating system. Regularly cleaning the internals of your device helps prevent excessive heat generation and ensures optimal performance.
3. Reset your device's BIOS Settings. To reset your motherboard's BIOS settings, you can try uninstalling and then reinstalling the CMOS battery. By doing so, any stored settings or configurations that may have become corrupted will be cleared, and the system will start with default settings. This helps eliminate potential conflicts or misconfigurations that could be causing the issue you're experiencing.
4. Verify that the RAM module is installed correctly and functioning properly. If the RAM module is not properly seated, it can result in display issues. Try re-inserting the RAM module, ensuring it is securely in place. Alternatively, you can consider replacing the RAM module with the same type to eliminate any potential RAM-related problems.
5. Perform a thorough visual inspection of the circuit boards for any signs of burns or damaged components. If you observe any visible damage, such as burns or parts that appear to be physically damaged, the board likely needs to be replaced, especially if it's the board carrying the display cable connector. In our store, you can find both motherboard and daughterboard components for select Chromebook models.
