Acer Chromebook CB3-431-C5EX Troubleshooting
This troubleshooting page will help you diagnose problems with the 14" Acer Chromebook identified by model number CB3-431-C5EX.
- Chrome OS running very slowly
- Chromebook crashing/freezing
- Chromebook cannot connect to Wi-Fi
You are connected to the internet but webpages load extremely slowly.
Because many applications on Chromebooks are run on the cloud, syncing data often takes up a significant amount of bandwidth. Go to Google Drive, select "settings," and under "General" settings select the box that says "Sync Google Docs, Sheets, Slides & Drawings files to this computer so that you can edit offline." This will allow programs to be used without having them.
Try closing unnecessary browser windows and apps and then check to see if Chrome OS becomes more responsive.
Try updating your Chrome OS to the latest software to optimize performance and efficiency.
Your screen does not respond to track pad or keyboard input, turns black, or suddenly exits out of applications.
Turn your computer off and then disconnect all media devices such as USB drives. Next disconnect the AC power adapter and then remove the battery. Perform a hard reboot by holding down the power button for 7 seconds. Finally, reconnect the AC power adapter and turn the computer on without the battery connected. IF the Chromebook starts up normally you have finished the hard reboot.
A computer is only able to run when enough memory is allocated, so if it is all being used at a certain time it could cause a crash to occur. Start by deleting unnecessary files or applications, and end background processes that you are not using in task manager: press ctrl + shift + esc and go to the processes tab. If this does not work, you may want to save all local files on a flash drive or external hard drive and reset the device to factory default by signing out of the chromebook, holding Ctrl + Alt + Shift + R, and selecting restart. When a box appears, select "reset."
Your Chromebook isn't connected to the internet. Wedge shaped symbol in the status area next to your account picture may be grayed out.
After turning on your Chromebook, check the wedge shaped symbol in the status area next to your photo. If it is grayed out, turn your wifi back on by clicking your account photo, click the wifi network, then click the switch so that it appears blue.
Turn your router and modem off and wait for 10 seconds. Turn both the router and modem back on again and check network connectivity.
Some older routers are unable to work with Chrome OS. Try connecting to another Wi-Fi source. If this works, try to replace your old router with a newer one as the router may be incompatible with Chrome OS.
Sometimes simply rebooting your Chromebook can fix Wi-Fi connectivity issues.
