Joakim_W, thanks so much for sharing your success story with us. We love to hear about a happy story and openSUSE together. The battery story was also very interesting. My previous laptop was a Dell D610 and perhaps 4 years or so ago, I too had to replace both batteries I had. The Laptop on fire story was kind of scarey, but the reality was I got two new batteries just about the time those old ones started acting up and it gave me a new lease on battery life.
In any event, if we have not already said so before, welcome to the openSUSE forums and please do not hesitate to ask for help for your computer or your fianceeās computer and we also wish you much success in your upcoming marriage.
Thank You,
