I'm looking to replace the battery in my Eurocom Tornado F5. It's served me well but the battery is clearly on its last legs, as being unplugged for more than a few minutes causes it to shut down immediately. I did a cursory search of this thread and didn't find the answer to the following questions, so any help would be appreciated: Is the battery something I can replace myself? How involved would it be? Judging from a few comments, it sounds like it would basically involve a simple unplugging to detach the old and plug in / reattach the new one... is that about right? Would I be able to buy the battery direct from Eurocom, or should I source it elsewhere?
