Hi again!
Wow, thanks!! Now it's working again.
What I did: plugged it itnto a usb 3-port, that as I understand it provides more power. After a few minutes it began reacting. So it seems the battery was flat.
I had abosulutely no idea that it could display a page without any battery. And what contributed to that confusion was that it did freeze while I was reading, and by then the battery was charged, so my hunch was that when the battery died, it would shut down the page. But that was not the fact. Interesting..
So, it's up and running, or rather, charging through the night. I've learned something, hopefully others can find it useful too.
Thanks a lot, guys!!
Magnus
