The device cannot see or connect to nearby wireless networks.

Either the Wi-Fi or Network settings on your computer are not set correctly. Navigate to Wi-Fi settings to ensure that Wi-Fi is enabled on your device and that you can see nearby networks. If you are connected and still cannot access the internet, navigate to your network settings and ensure they are correctly set.

If your device cannot see any local networks yet you can still connect fine using an Ethernet cable, you may have to replace your Wi-Fi/Bluetooth card. A guide on how to do this can be found here.

Integrated or external display is incorrectly displaying desired output.

Check to ensure that the cable connecting your monitor to the laptop is connected firmly in place. Ensure that any screws on your cable headers are tightened down if they exist. It may be necessary to test the cable, external display, or both using another device to ensure they are functioning properly.

Ensure that the display resolution for your monitor is correctly set. This can be adjusted in Windows by right clicking your desktop and selecting “Display Settings”.

If your screen is showing a checkerboard pattern of squares, dots, or lines, wildly incorrect colors,  or large patches of stuck pixels, your computer’s drivers may not be up to date. Ensure that you have installed the latest and correct drivers for your specific version of windows.

Keyboard is not responding, appears to be broken, missing keys, or keys are stuck in the up or down position.

If one or all of the keys are stuck in place, then there might be something physically holding the key up or down. If a key is stuck like this, begin by removing the key from its slot. Visually inspect under the key for anything that would obstruct the key’s movement. Clean the area and double check there is nothing inhibiting a keystroke or underneath the key itself. Check for any sticky or viscous residue that might hold the key in place and make sure to clean that from the keyboard as well. Once thoroughly cleaned, snap the removed key back into place and test the key’s functionality again. If the key continues to remain stuck, check the keys immediately surrounding the key in question and inspect if they are impeding the stuck key. If not, consider replacing the keyboard with a new one.

If there are keys missing from the keyboard, or keys are broken or cracked, they will need to be replaced. Attempt to locate the missing key. If unable to find it, a similar one will have to be purchased. Make sure it is the correct dimensions as the device’s keys and has the appropriate letter, number, or symbol printed on it. Align the new or found key over the space it is suppose to be within on the keyboard. With the appropriate connection, the key should gently snap into place with steady and gradual pressure directly over the center of the key.

Attempt to clean the space under each of the keys first and check for any other hardware issues. Next, try reinstalling the keyboard driver by going to Device Manager, scrolling down to Keyboards, and open that setting. If there is an exclamation mark next to “Standard PS/2 Keyboard”, then Windows has detected a problem with the keyboard. If so, right click on “Standard PS/2 Keyboard”, and if there is an available update, enable it. If that too fails, uninstall the keyboard and reboot your computer. Also try uninstalling secondary keyboards that might appear under the device manager. To test keyboard hardware, try to boot into the BIOS while starting up. Make sure to press the correct key, usually F2, F8, or F12 repeatedly to boot into the BIOS. If booting into the BIOS fails and the device boots into Windows instead, that means there is likely a loose or disconnected cable on the motherboard Use this guide here to replace or reconnect the Panasonic Toughbook CF-53 keyboard.

Select the Boot tab in the BIOS setup and move your Operating System above the BIOS in boot order. Then select the OS and either double click or press enter. The device should now boot into your primary OS.

If the device is booting into an error message for a corrupt hard drive or Operating System files, you can either use a USB Boot Drive or replace the hard drive with a functioning one with an OS installed.

It is possible that an error has occurred with the computer’s Random Access Memory, whether that be with the RAM itself or the way it was installed. If this is the case, it will be necessary to replace the RAM with this guide here.

The laptop is not reading or writing inserted discs correctly.

Ensure that the disks are properly installed and functional. If the discs in question are confirmed to work in another device, the most likely cause is due to some form of fault in the optical drive itself. In this case it will be necessary to replace the optical drive as is shown in this guide.
