HP Prime Graphing Calculator G8X92AA Troubleshooting

The calculator does not turn on or does not respond.

A new fully charged HP Prime should last approximately 25 hours if it is being used continuously, and approximately 48 days in standby. The calculator comes with USB and power supply. Therefore, the first step should plug it in to charge.

Try charging other device with your charger to verify it works. If the charger does not charge the device, a new charger should be purchased.

To prove this, plug your calculator using a charger that you know it works. If it does not charge, the battery has to be replaced.

Your calculator is not responding to touch or key inputs.

Restart the calculator by removing the back-cover and taking out the battery. Wait 30 seconds and insert the battery back into position. Put the cover back on and turn on the calculator if it is not on already.

If all attempts have failed and touch screen is still not responding, replace the digitizer.

The outer calculator casing is cracked or physically damaged.

If the casing for your calculator shows signs of physical damage such as cracking or warping, it should be replaced using this guide.

Individual or multiple keys will not register input or are physically broken.

No keys will respond or generate input to the calculator. In this case, replace the entire keyboard.

Individual or multiple keys cannot be pressed, or are sticking down after pressed generating unwanted input. To remedy this, remove the appropriate assembly of keys (you will notice the keys are all connected in two segments). Once removed carefully observe to ensure nothing is obstructing the keys from the rubber contacts and the sensors underneath. Clean the area if necessary using a clean cloth. Once you are finished, reassemble your keyboard sandwich.

You are having issues using or seeing content on your screen.

If the calculator’s screen was damage or somehow it broke the screen, this could cause some screen issues. In this case, your screen should be replaced.

In order to diagnose a faulty backlight and ensure the device is not dead, you can plug the calculator into the computer to see if it reads or recognize the device. If the computer recognizes the device, we can conclude the device is not dead and the issue may reside in the screen. If this is the case, a new backlight or entirely new screen should be installed.
