Computer doesn't turn on
Nothing you do will make your Chromebook turn on.
If no lights turn on when the power button is pressed or the laptop is opened, your battery may be dead. Plug in your power cable and turn on the computer again. If the computer turns on, keep it plugged in until the battery is charged. If nothing happens after plugging it in, read on.

Your laptop will 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 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 overheating in the future. If your problem persists, refer to the Broken motherboard troubleshooting below.
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 to have a functioning computer. See the Hard Drive Replacement Guide for more information.
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. Here's Acer's support site.
Computer doesn't connect to the internet
The internet is beating you at hide and seek.
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.
Broken wireless card
If your laptop does not connect to the network that other devices will connect to, your wireless card is probably faulty. A broken wireless card will prevent a connection or will drop the connection randomly. Connect your laptop to another network to determine that the problem is with your wireless card and not your router. If it does not connect to another network, refer to the Wireless Card Replacement Guide.
Battery doesn't charge
After all efforts, you're still powerless.
Broken Wall Outlet
If your laptop does not charge while plugged into that outlet, you could have a broken wall outlet. Check all switches and power strips that are attached to that outlet to test that they are in proper working order. Plug something else into the same outlet. If the other device does not get power after these steps, your outlet is broken and should be checked out by an electrician. 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. Most computer stores will sell you a new cable.
Dirty Battery Connection
If your battery does not charge, remove battery following the Battery Replacement Guide, and clean the battery connection and battery with compressed air or a clean dry cloth.
If the computer runs normally when the power cable is plugged in but turns off when the cable is removed, the battery is broken. A broken battery can have multiple causes. If you have had the computer for more than a year, the battery will lose its ability to charge and will run out of charge very quickly. Another cause is a broken motherboard, which will cause the computer to not recognize or charge the battery. Replace the broken battery with the identical model from the manufacturer. If the problem persists, contact Acer Support to get your motherboard replaced.
Computer doesn't cool down
Quite literally, it's too hot to handle.
If the laptop's cooling vents are blocked, the laptop will get too hot. The vents are a series of vertical slits on the side of the laptop and a square of holes on the bottom. Ensure that these vents are not blocked by an object (blanket, pillow, etc.) 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. Follow the Cooling Fan Replacement Guide to expose the fan, but do not remove it. Use compressed air to clean it out. If the device still runs hot, move on too the next option.
Broken Cooling Fan
If the cooling fan is broken, little or no air will come out of the cooling vent. Put your hand next to the vent to test if your fan is functioning. If no air is flowing, see the Cooling Fan Replacement Guide.
Computer doesn't respond to input
There has been a slowdown in your relationship.
Device is overheating
If your device is too hot to stay in constant contact with, 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, but if your device runs slower than usual, or crashes frequently, you may be running out of RAM. Refer to the RAM Replacement Guide to see how to replace or add more RAM.
