Samsung Chromebook Series 5 3G Troubleshooting
Chromebook won't turn on
The first thing to check for when your Chromebook won't turn on is a dead battery. Plug the unit in via AC charger and let it charge for at least 30 min to an hour and try turning it on again.
A "blank screen" is when the light on the power button is on, but the screen remains black.
First try powering your Chromebook off by holding the power button down for six seconds, then turning it back on again. If you cannot power it off, let the battery run out until it powers off, then charge the battery back up and power it on again.
If this does not work, reset your Chromebook with the following steps:
- Power off your Chromebook off.
- Insert a paperclip into the reset hole located to the back feet on the underside of the laptop.
- While pressing the paperclip in, press power button.
If no lights turn on when the power button is pressed and the computer is very hot on the bottom, your computer may be overheated. You will have to wait a few minutes until it has cooled down. Unplug the laptop from its power cable and let it sit with the vents unobstructed. After at least 10-15 minutes, try turning the computer on again. If it boots normally, the computer was too hot. Try using the laptop on a hard surface to help prevent this in the future.
Corrupt operating system
If the computer lights up but gives you a message saying "Operating System Not Found", your operating system may be corrupted. You will have to reinstall Chrome OS to fix this error. Follow Google’s Recover your Chromebook article to reinstall Chrome OS. If the error does not go away after a successful reinstall, continue reading.
Broken hard drive
If lights turn on when the power button is pressed, but ChromeOS does not load, your computer’s hard drive may be broken. The screen will display a message saying, “No operating system found.” You will have to replace the hard drive.
If no lights turn on when the power button is pressed even when the battery is charged, your motherboard is broken. If it is still covered by warranty, you will have to send the laptop into the manufacturer to have this replaced.
Computer doesn't connect to the internet
Incorrect WiFi password
If your laptop does not connect to the Internet, the password you entered for the Wi-Fi could be wrong or recently changed. Try reentering the network password.
Broken or improperly-set-up wireless router
If your laptop does not connect to the Internet, your router could be faulty. Try connecting a different device to the same wireless network. If that device has issues connecting, reset the router and check that all cables are plugged in correctly. If after a reset, devices still can't connect to the router, the router is faulty or your Internet provider is down.
Battery doesn't charge
Broken Wall Outlet
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. If the other device does not get power after these steps, your outlet is broken. If the other device does get power, try another guide in this section.
Broken Power Cable
If the computer does not charge a functional battery, the power cable might be faulty. 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 in the following link. Power Adapter.
If the computer runs normally when the power cable is plugged in but turns off when the cable is removed, the battery is broken. If you have had the computer for more than a year, the battery will lose its ability to charge and will die very quickly. Replace the broken battery with the identical model from the manufacturer.
Computer won't cool down
If the laptop's cooling vents are blocked, the laptop will get too hot. Ensure that these vents are not blocked by anything. If the computer stays hotter than normal, read on.
If the internal cooling fan is clogged with dust, it will not be able to cool the inside of the computer. Use compressed air to clean it out. If the device still runs hot, move on to the next option.
Computer is too slow or doesn't respond to input
Device is overheating
If your device is too hot, the operating system will slow down. Feel the bottom of the device to see if it is unusually warm. Shut down the computer and let it cool down. If your laptop still overheats, see the Computer doesn't cool down section above.
Too many programs open
If you have many tabs open, your computer will slow down. Close a few tabs and see if the computer becomes more responsive. Restart the computer if it does not.
Not enough memory (RAM)
This is not a common problem with chromebooks, but if your device runs slower than usual, or crashes frequently, you may be running out of RAM.
