Acer Chromebook USB Ports Not Working

Before undertaking significant repairs on your device, you must go through basic troubleshooting steps. These steps can often resolve issues without the need for extensive repairs. Please ensure you check the following.

• Ensure that your USB device is on and not faulty. Sometimes, the issue could be with the USB device, not the Chromebook. Be sure to test the USB devices on another device to confirm if they work correctly. You should also try connecting different USB devices to your Acer Chromebook to see if the issue persists. Some large storage devices might also require a separate power source, so ensure your USB device is powered on or connected to power. If you find the issue with your USB device, try seeing if the device is in our Computer Hardware Section.
• Test the USB device with a different USB port. You can determine if the port itself is faulty by testing your USB device with a different USB port. If the USB device does not connect with your device, then the likely culprit is the USB device itself. Otherwise, the USB port on your Chromebook is the culprit.
• Make sure that both ends of the USB device are seated correctly. A proper connection is needed to plug your device into your Chromebook's USB port. Try reseating the USB end of your device into your Chromebook's USB port, and ensure the connection does not feel loose. If your USB device plugs into the USB device, ensure that this end is properly connected.
• Restart your Chromebook. Restarting your Chromebook will clear out any problematic temporary files and reset any software components that might not be responsive. To restart your Chromebook, click on the system tray, select the power icon, and choose Restart. You can restart your Chromebook by pressing the Esc + Refresh (F3) keys simultaneously and then pressing the Power button.

If these quick tips cannot resolve the issue with your USB ports, try the more in-depth troubleshooting tips below.

If the USB device you are attempting to use is a storage device, it is important to keep in mind that only some storage formats are compatible with Chrome OS. If your USB is running in an unsupported format, your storage drive won’t work. The following supported file formats are listed below.

• FAT (FAT16, FAT32, exFAT)
• HFS+ (read-only on journaled HFS+)
• ISO9660 (read-only)
• MTP
• NTFS (Supported for ChromeOS after 2021)
• UDF (read-only)

If your storage device is not one of the listed file formats, you can format your drive using the following steps.

1. Open Explorer.
2. Right-click on the USB drive and select Format from the context menu.
3. In the File System option, choose a supported format.
4. Click on the Format button.

If converting your storage device could not fix the problem, or if this section does not apply to you, try the next section.

If you cannot use the USB ports on your Acer Chromebook, there may be an issue with the physical hardware.

• Ensure that your USB Ports are clean and free of debris. USB devices rely on several metal pins that need proper contact with the pins inside the USB connector. If dust or debris has gotten into the USB port, this could cause the connection between the pins to not be complete. You can use a dust blower and 90% rubbing alcohol to clean out the port.
• Perform a thorough visual inspection of the USB Ports on your Chromebook. If your USB port has become damaged, then this can cause issues with how your USB device connects to your Chromebook. Perform a visual inspection of your Chromebook's USB ports, looking for any breaks in the plastic support tang or bent or broken contacts. If either of these is broken, you must replace the port or the board the port is connected to. This will be specific to your device.

If there is no accumulated dust or visible damage in your USB ports, move to the next section.

If the above tips cannot resolve the issue, there might be an underlying issue with your device's operating system. Here are a few issues that might be causing your issue and how you can resolve them.

You can check if your operating system is outdated by going to Settings > About Chrome OS > Check for Updates. Install any available updates. Updates often include bug fixes and performance improvements for your operating system.

If updating your device could not resolve the issue, you might need to Powerwash it. There are several ways to do this, but the easiest way is to follow the instructions below to Powerwash your Acer Chromebook.

Note: This will factory reset your device, so be sure to back up all your data to either Google Drive or an external storage device.

Additional information on Powerwashing your device can be found here.

1. Sign out of your Chromebook by clicking on your profile picture in the bottom right corner of the screen and selecting Sign Out. (You'll need to be at the login screen)
2. Press the following key combination on the login screen: Ctrl + Shift + Alt + R Twice.
3. A dialog box will appear, asking you to confirm that you want to Powerwash your Chromebook. Click on the Powerwash button to continue.
4. Follow the on-screen instructions to complete the Powerwash process. Your Chromebook will be factory reset.
5. After the Powerwash is complete, your Chromebook will start as if it were a new device. Follow the on-screen instructions to set up your Chromebook, including connecting to a WiFi network and signing in with your Google Account. Once this is done, check if you can use your USB devices.

Alternatively, you can completely restore ChromeOS using Google's ChromeOS Recovery Tool. This tool can address any potential software issues causing your device to have trouble seeing your USB devices. The instructions for creating a ChromeOS recovery disk are below, but 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 you can use your USB device.

If the above sections have been unable to resolve the issue, then there is a possibility that there may be an issue with your device's internal components.

• Perform a thorough visual inspection of the motherboard for any signs of burns or damaged components. If you observe any visible damage, such as burns or components that appear to be physically damaged, the motherboard likely needs to be replaced. This will be specific to your Chromebook.
