OSTC Sport does not react after inserting a new battery

[jonas.kiem]

Hi guys,
After the battery of my Sport died i inserted a new 3.6V battery into it. As soon as i close the cap the computer starts to boot but nothing more. The screen becomes blacks after the Heinrich Weikamp logo and does not respond to any activity. I can press all buttons but still everything black. The only thing that happens is that the LED turns green. I have no idea what to do.
Did anybody else face this kind of problem already?
Hope you have an answer.
Thank you!

Hello!
I had the same problem….
My battery was too long for the ostc.

Thanks for the reply but that cannot be the problem. The new battery is the same size as the old one which worked perfect. Meanwhile not even the logo appears when the battery is setted.

I also used the same battery multiple times before and that was the problem! I measured the used battery and then checked for a smaller one…. And after this, the ostc worked again!
