I recently acquired a Sony Vaio PCG-505TR with a 300mhz Pentium and Windows 98 in a lot. The computer is in overall good cosmetic condition without anything missing. However, the computer will not turn on when I use my Targus APA68US. The other computer in the lot, a Fujitsu Lifebook 735Dx works fine with this power adapter. The only differnece is that the Fujitsu Lifebook is DC 16V 2.7A, while the Vaio is 16V 2.0A. Can someone help me, I had a similar Vaio back in the day.
