I am traveling abroad to Germany for the first time. I have an old Dell M5010 laptop. With a battery that lasts about 20 mins (I can deal with it, as I only use it on the train, where there's plug sockets.) I have a plug adapter that is designed to work in France. As far as I can tell it has no surge protection or anything fancy like that.
Can I 1. Use the laptop and adaptor in Germany with a "reasonably" low chance of spontaneous combustion.
2. Find somewhere that sells new batteries for this thing at a reasonable price, as I'm not quite rich enough yet to be forking out on a new laptop at short notice, when the most it goes through is Twitch.tv viewing.
