<\/a><\/figure><\/div>\n\n1. Disconnect External Devices or Accessories\n<\/h2>\n\n
External accessories (monitor, webcam, docking station, etc.) or storage devices can interrupt your Chromebook\u2019s boot process. Unplug any accessory or device (thumb drives, SD cards, etc.) from your Chromebook and try turning it back on.\n<\/p>\n\n
2. Remove and Reinsert Your Chromebook\u2019s Battery\n<\/h2>\n\n
If your Chromebook\u2019s battery is detachable, removing and reinserting the battery might stop it from turning off during usage. Ensure the battery compartment is clean and free of dust, dirt, or any material that could interfere with the battery connection. Also, use a clean and dry cloth to wipe dirt off the metal contacts on the battery.\n<\/p>\n\n
<\/a><\/figure><\/div>\n\nReplace the battery if it’s swollen or has any physical damage. Otherwise, check the battery\u2019s health (see next section) if your Chromebook keeps shutting down on battery power.\n<\/p>\n\n
3. Check Your Chromebook\u2019s Battery Health\n<\/h2>\n\n
When disconnected from a power source, Chromebooks with degrading or faulty batteries<\/a> might fail to boot or stay powered on.\n<\/p>\n\n Follow the steps below to check your Chromebook\u2019s battery health in Crosh\u2014the ChromeOS Command Shell environment.\n<\/p>\n\n Wait for Crosh to run the command (about 3-5 minutes) and proceed to the next step.\n<\/p>\n\n An 80% battery_health (or lower) indicates a degrading battery. That means your Chromebook can no longer retain up to 80% of its original capacity.\n<\/p>\n\n Expect your Chromebook to discharge quicker (than usual) or start turning off without warning when its \u201cbattery_health\u201d rating hits 80% or lower.\n<\/p>\n\n Contact your Chromebook manufacturer<\/a>, administrator, or any computer technician to have the dying or worn-out battery replaced. Your Chromebook manufacturer won\u2019t charge you for battery service or replacement if your device is under warranty.\n<\/p>\n\n ChromeOS has a Diagnostics tool that detects battery failure and charging issues. Turn on your Chromebook and follow the steps below to run a battery discharge test before it shuts down.\n<\/p>\n\n The test measures the rate at which your Chromebook\u2019s battery charges and discharges over a specific period.\n<\/p>\n\n Your Chromebook will fail the test if there\u2019s an issue with its battery or charging port. Contact your Chromebook manufacturer to have its battery and charging port examined. You should read our tutorial on fixing Chromebook charging issues<\/a> for more troubleshooting steps.\n<\/p>\n\n Laptops sometimes restart intermittently or temporarily stay powered off to prevent heat-induced damage. Your Chromebook might overheat due to poor ventilation or dirt build-up in the air vent. Also, expect your Chromebook to overheat if its cooling fan is malfunctioning or clogged.\n<\/p>\n\n If the base of your Chromebook feels warm or hot, leave it to cool before turning it back on. Better yet, place it on a laptop stand or cooling pad for faster cooling<\/a>.\n<\/p>\n\n Also, check your Chromebook\u2019s air vent for dust, dirt, or grime blocking air inlet and outflow. Swipe the air vent with a clean and dry cloth to remove dust or dirt. Dampen the cloth with cleaning fluid to remove grime stuck on the vent\u2019s grills and crevices.\n<\/p>\n\n You can also use compressed air to blow out dirt and dust. Doing so will improve air circulation and stop your Chromebook from overheating. Closing unneeded browser tabs and applications can also reduce CPU workload and temperature. If you\u2019re charging your Chromebook, unplug the power supply for a few minutes.\n<\/p>\n\n Contact your Chromebook manufacturer or a computer technician if the CPU fan doesn\u2019t work, or the overheating persists. If you use a work or school Chromebook, report the persistent shutdown issue to your administrator.\n<\/p>\n\n Bugs in your Chromebook\u2019s operating system can also cause it to keep shutting down without warning. If your Chromebook briefly stays on before shutting down, update its operating system<\/a> as quickly as possible.\n<\/p>\n\n Join a Wi-Fi\/Ethernet network, head to Settings<\/span> > About ChromeOS<\/span>, and select Check for updates<\/span> to update your Chromebook manually.\n<\/p>\n\n You\u2019ll see an option to reboot your Chromebook if there\u2019s a pending or pre-downloaded software update. Select the Restart<\/span> button to install pending updates.\n<\/p>\n\n Hard reset your Chromebook (see next section) if it won\u2019t stay on despite updating its software to the latest version.\n<\/p>\n\n Hard resetting your Chromebook won\u2019t delete personal files or applications. However, the operation might remove some files in the \u201cDownloads\u201d folder. Back up the folder or important files to Google Drive or an external storage device before performing a hardware reset.\n<\/p>\n\n You can also hard reset your Chromebook by pressing and holding the Back<\/span> + Refresh<\/span> + Power<\/span> buttons for 10-15 seconds.\n<\/p>\n\n The following Chromebook models have a special reset button: Acer AC700, Lenovo Thinkpad X131e, Samsung Series 5, and Series 5 550. You\u2019ll find the reset button in a hole at the bottom of your Chromebook\u2019s case.\n<\/p>\n\n Turn off your Chromebook, unplug its charger, and follow the steps below to reset its hardware.\n<\/p>\n\n ChromeOS runs applications and web pages in a restricted \u201csandbox\u201d environment that safeguards Chromebooks from malware infection. The chances of malware infection in ChromeOS are slim, but it\u2019s not entirely impossible.\n<\/p>\n\n Stubborn malware<\/a> that manages to creep into your Chromebook\u2019s operating system can cause startup and power issues. Run a complete system scan using third-party antivirus\/security<\/a> to detect and remove malware from your device.\n<\/p>\n\n Powerwashing your Chromebook or resetting it to factory settings will permanently delete everything on the hard drive. Back up important files before running the powerwash\u2014if your Chromebook stays on long enough for you to do so.\n<\/p>\n\n Head to Settings<\/span> > Advanced<\/span> > Reset settings<\/span> and select the Reset<\/span> button.\n<\/p>\n\n<\/a><\/figure><\/div>\n\n<\/a><\/figure><\/div>\n\n<\/a><\/figure><\/div>\n\n4.
