Hello,
Thanks @yvmuell and @AnotherElk for your replies!
Yes, from the guide I linked I figured it’s a completely discharged battery. I have tried another charger, but as I was away I didn’t have access to another cable just yet. Will do that tomorrow morning when at work.
As suggested in the guide I linked - about 15 minutes or so. Didn’t dare to keep it in longer. I tried that multiple times (with breaks in between).
Normally I never do this because I know it’s bad for the battery, but this time I forgot I left it in the charger and it stayed overnight. So I don’t know what happened - if I didn’t plug the charger properly, if it got overheated somehow and blocked loading as some safety measure… No idea
Oh, thank you! That’s good to know. I was already wondering why this wasn’t happening.
Thanks for the links! I would like to avoid buying another piece of electrical equipment if possible, but it’s good to know this option exists. And it’s an interesting read.
