Samsung Chromebook Series 5 3G Troubleshooting

1. Check the power connection. If your laptop does not charge while plugged into that outlet, you could have a broken wall outlet. Plug something else into the same outlet. Your outlet is broken if the other device does not get power after these steps. If the other device does get power, try another guide in this section.
2. Check your power cable and adapter. The power cable might be faulty if the computer does not charge a functional battery. The easiest way to check this is to borrow an identical power cable to test in your laptop. If your battery charges with the borrowed cable, you have a faulty power cable. Purchase a new power adapter at the following link—power Adapter.
3. Verify Charging Indicator: When you plug in your Chromebook, observe if the charging indicator light (if present) lights up or changes color, as this signifies if the device is receiving power.
4. Perform a Hard Reset: Perform a hard reset by performing the following steps:
   1. Disconnect the charger from your Chromebook.
   2. Press and hold the power button for at least 10 seconds, then release it.
   3. Reconnect the charger and check if the device starts charging.

If the above steps do not resolve the issue, proceed to the more detailed troubleshooting steps below.

• Restart WWAN Board: Press and hold the refresh key (usually located where the F3 key would be) and tap the power key. Release the keys once your Chromebook restarts. This will refresh the network card and may resolve any temporary issues.
• Update network drivers: Ensure your Chromebook's operating system is current. Go to "Settings"> "About Chrome OS"> "Check for Updates." Install any available updates, including updates for network drivers.
• Test with an external Wireless Adapter: Using a wireless adapter, you can ensure your device can reach the network and determine if your WWAN Board needs replacing. However, if you cannot reach the WiFi with an external adapter, there is likely an issue with your device's Motherboard.
• Replace the WWAN Board: If all else fails, you can replace your device's network card and see if your device can detect your wireless network. iFixit does feature a guide for replacing your Chromebook's WWAN Board.

If these steps have failed, there is most likely an issue with your device's Motherboard.

Suppose your device is still not seeing your wireless network 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. Reset your device's BIOS Settings. To reset your Motherboard's BIOS settings, you can try uninstalling and then reinstalling the CMOS battery found attached to your Chromebook's Motherboard. 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.
2. Check for Defects that would cause Network Connectivity issues: Ensure that your Motherboard is not bending or experiencing any issues that would not allow your WWAN Board to not sit correctly in its port.
3. 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.

• Close Unnecessary Tabs and Applications: Multiple open tabs and applications can consume system resources and impact performance. Keep only the essential ones open. You can see which applications use many resources using ChromeOS's Task Manager by tapping the Search button and Esc on your keyboard.
• 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.
• Check Your Internet Connection: If web-based applications are particularly sluggish, there might be a good chance of an issue with your network connection.

One of the reasons that your Chromebook could be running slowly could be due to several different issues caused by the operating system.

• The potential issue caused by Cached Data: If a cached file becomes corrupted or enough of them are stored, it can cause your system to become slow. You can clear your browsing data by following the below steps.
  • Open Settings: Click on the system tray and the gear-shaped "Settings" icon to open the Chromebook settings.
  • Expand "Advanced": Scroll down and click on the "Advanced" section to reveal additional settings.
  • Click on "Privacy and Security": Under the Advanced section, click "Privacy and Security" to access related settings.
  • Click on "Clear Browsing Data": In the Privacy and Security section, click "Clear Browsing Data" to open the data clearing options.
• Outdated Operating System: 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 often contain performance improvements for your operating system.

Disabling or removing unnecessary extensions can significantly improve the speed and performance of your Chromebook.
