Hello, I have a GRAPH 90+e calculator that I was using without any problems before the holidays, but now I can't turn it on (I've already tried the restart button). When I plug it into my computer, there is a white display with a sign that it's charging for 2 seconds, then it turns off...

Hello!

The first thing to check is the battery status, whether it's fully charged. If the battery is dead, connect the calculator to the computer via the USB cable and let it charge for several hours. If the device still doesn't turn on, the problem may be with the battery itself. In that case, you might consider replacing it.
Also check if the calculator's software needs to be updated. You can download the latest software versions from the manufacturer's official website. If, despite these checks and actions, the problem persists, it would be best to directly contact the manufacturer's customer service or consult a specialized technician.
