Laptop is unresponsive when attempting to start up.

If the computer is unresponsive and not turning on, check to make sure your battery is connected properly to your laptop and that it has enough charge to turn the laptop on. If it isn’t charged, connect the power adapter to a working outlet in order to charge it.

Check that the power source you’re using for the power adapter is functioning properly. If it is, and the indicator light on your power adapter is not illuminated, it is likely that your adapter needs to be replaced.

If your laptop only turns on and works while your power adapter is plugged in, it is likely your battery is faulty and needs to be replaced. Check to see if your battery is replaceable under warranty through Acer, and if it isn’t purchase a new battery and replace using our Battery Replacement Guide.

If your new working battery is installed or the power adapter is plugged into your laptop and the device still will not turn on, it is likely a motherboard issue.

Laptop may not find wifi networks or connect to found networks.

Check and make sure your wireless network is successfully connecting to other devices such as your cellphone. If your other devices aren't connecting check your wireless connection. You can do this by right clicking on the wireless network icon on the bottom right of your screen and clicking "Troubleshoot Problems." It's possible your wireless network isn't connecting because there are no networks available or there is an issue with your router. If troublehshooting doesn't solve the connection issue, try unplugging your router for one minute, leaving it unplugged for one minute and then plugging it back in. If connection doesn't resume, try calling your internet provider.

Check to make sure that your laptop's wireless function is not disabled by clicking "Fn" and "F3" on your keyboard at the same time. If that method doesn't work you can also click Start, type "Network and Sharing Center" in the "Search programs and files" search bar, and hit Enter. Then click "Change adapter settings" in the left margin of the window. Then right-click the connection icon and select "Enable."

If you are confident that the wireless network in your home is working and the device is WiFi enabled, check your Acer wireless drivers. Use the Drivers Update Tool to automatically update all the Drivers for you. Since this will require internet connection, use wired connection via an ethernet cable.

The laptop screen keeps turning black and may get pink and blue lines across it when the screen isn’t black.

Make sure your drivers are up to date. Go to Display > Device Manager and see if there are any yellow exclamation points. If there are, update the drivers.

Hook your laptop up to an external monitor. If you do not see an image on the monitor, then you might have a graphics card problem. If you can see an image on the monitor, your ribbon cable may be faulty.

If you can’t see anything on an external monitor, your graphics card is bad and may need replacing. You will either need to send it in to a manufacturer or replace the motherboard, as they are integrated.
