Hi.
Ok, Cedric seems to have multiple power sources for his notebook so he offered me to use one of these. Bad part is, Cedrics notebook is much older than mine and, of cource, the power sources are not compatible. Fortunatly, both systems are running on similar voltage (19.5V mine and 20V Cedric) and similars power (90W both), so we decided just to cut the cable and put my tip to his powersource. While reconnecting, I realized that my power source has 2 power cables inside the cord and one additional, smaller (data?) cable.
Now, I tested it - and something interesting happend: My notebook started and, at once, complained that I am not using the orignal power source, but some kind of crappy cheap replacement and that I, please, buy a new one at http://www.dell.de. It also said, that I can use the computer like that, but some features are not available or run with reduced efficiency. In this case, it refers to the fact the the battery won't be loaded (and maybe some other thing I did not notice). This is very interesting, as the specs of both power source are nearly identical (in fact, Cedrics is even stronger than mine). Thems like Dell found an interesting way of convincing people of using original replacement parts... (Right now, I don't care as I don't need the battery.). So, it seems that this fix is ok like that until I can convince the dell customer service that they should do something which justifies the couple hundred Euros I paid for service and support. But if anybody has access to a soldering device, this would be great (right now, I taped the cables together - it works, but looks very crappy and unstable)).
Well, have a nice day, cheers Christoph
