Try this -  open the lilttle battery door in the back. Take out the battery. Connect the USB power. Does the calcualator turn on? Great! Now with the USB still plugged, put the battery back in. Does it stay on? Great!

 

Now leave it for 5-10 minutes plugged in. Remove the USB and it hopefully stays on. Charge it and you should be good.

 

Sometimes a new unit that has been sitting for a long time gets the battery "stuck" because it is so low. This will unstick it if that is the case.

Thank you all for responding so quickly and sorry that I respond so slowly. Im a school student in the Netherlands and tomorrow I need the calculator for a test. In the normal lessons I can use it with a powerbank, but during a test the teacher wants all of us to be in exam mode with a special device or something. This means that I cant use my powerbank to power it. The main problem is that I cant use it with a usb cord. I updated the calculator in the delivered program and after that I cant use it without a supply. I tried all the fixes you guys sended, but nothing works. The battery is ok in te utilty and i formatted the c drive. I also tried the non battery fix but still nothing works. I bought it 3 weeks ago so it has its warranty so I can send it back, but thats to late for tomorrows test. Can anybody still help me out?

 

Kind regards,

Teun
