Broken power connector on the motherboard is the most likely possibility. Power connectors fracture because laptop makers (all brands) simply solder them to the motherboard, rather than anchoring them more solidly. Solder is soft, and after so many insertions and removals of the power connector, the solder fractures, leaving no connection or, at best, a sporadic one. If automobiles were made to the same quality standard, you'be driving along and one of the wheels would fall off. (Oops! Wasn't that Toyota?) If you want a replacement D505 motherboard, it is yours for $50 plus shipping (around $10). I have not done extensive testing on the D505's in my collection, but a number of them powered up to the BIOS. I have a simple, but effective test procedure to make sure laptop motherboards work 100% before I send them out... Ben Myers

But I live in a small european country without any private Dell repair. If I contact the local Dell representative, they are only interested in getting me to buy a new laptop. So my plan is to open the case and try to solder some electrical connection. If it ends with a disaster, I could buy another 4year old laptop for less than $100. No panic....
