Acer Chromebook R 11 CB5-132T-C9KK Troubleshooting

The computer does not respond when turned on or opened.

If your laptop is not turning on, try plugging in the device's charger and wait about 2 hours. If after 2 hours the device does not turn on, see other solutions.

If your Chromebook is not already plugged in, plug in the charger. Ensure the plug is firmly connected to both the computer and the outlet on the wall. Also, make sure the power adaptor is working.

If the charger seems to be working, your screen brightness might be low. Locate the brightness buttons on the Chromebook at the top of the keyboard. Then, press the increase brightness button several times.

If available, try connecting an external monitor to your Chromebook. If the screen displays on the new monitor, the issue is the Chromebook's screen. Consider replacing the screen.

The Chromebook works, but loads slowly or lags.

When your Chromebook is on, check the Wifi Status. If you are not connected to a Wifi source, connect to one by searching the networks near you. If you're already connected to Wifi, check and reset your at-home router by unplugging the router, waiting 2 minutes, and then plugging it back in.

Your Chromebook may be running slowly because of the number of tabs and/or extensions open. Close all unused applications and extensions. To disable extensions, open the Chrome browser, click on Menu, select more tools, select Extensions, then disable or delete unused extensions.

Your Chromebook might be running slowly because you do not have enough RAM, or your RAM is insufficient for the programs on your device. Consider installing, or upgrading, RAM into your Chromebook.

Sections, or all, of the Chromebook's keyboard, are unresponsive when attempting to type.

If sections of the keyboard are not responding, take out those specific letters from the keyboard. Underneath each letter is a switch. Clean that switch and the surrounding area. After cleaning all the problematic letters, put them back in their places and see if they work.

If the whole keyboard does not respond, unscrew the back of the Chromebook. Open the back and ensure all connections to the keyboard are firmly in place and attached. Put the back of the Chromebook back on. If the keyboard is still not responding, consider replacing the keyboard.

If there are certain keys missing, you will need to replace them.

The Chromebook does not respond or does not indicate the charging status when the charger is plugged in.

Make sure the charger is firmly connected to the Chromebook. To go further, unplug the charger and plug it in again, pressing firmly. Then, make sure the charger is completely plugged into the outlet. Again, unplug and replug the charger from the outlet. If the Chromebook still fails to charge, see other solutions.

If your Chromebook is plugged into an outlet, unplug it. Then, try plugging the charger into a different outlet. If the Chromebook charges in a different outlet, the first outlet is faulty.

If the power adaptor is plugged in, examine the power adaptor for a light. If there is no visible light, the power adaptor is not working. Think about buying a replacement power adaptor.

When the Chromebook’s volume is on, the audio sounds muffled, crackled, or incoherent.

Locate the Chromebook's speakers (playing audio can help). Clean out any dust or other small materials that could be blocking the sound.

A lack of device memory can sometimes distort audio. Go to the device's settings and find your Chromebook's storage. If the storage is almost full, delete any unused applications, clear the device's trash can, and close out unnecessary applications.

Play audio without headphones, and then with headphones. If the audio is only distorted with headphones, there is a bad connection between the Chromebook and the headphones. Make sure the cord is firmly connected to the Chromebook. If your headphones connect through BlueTooth, disconnect the headphones from your Chromebook and then reconnect. If the audio remains distorted, your headphones may be faulty.
