Hello to all. $ [% f! I4 V! B! R) K e, T# ^
My name is Stefano and I write from Italy.
8 y7 N$ ]$ l; P. v- K3 p$ eI have just registered on this forum and I do not understand how it works yet because I do not know Chinese. I apologize.
$ x+ w0 } l8 `) s* j& jI too have a Dell D600 that does not charge, but power on.
, n& B6 l6 C7 ~) T0 sI tried to follow the suggestion of BANDAOT in your thread, but I have not solved the problem.
8 z* y8 |# Y3 f5 g) {( f% RI fear that it is a problem of recognition AC adapter because when I insert the power cord, measuring with the oscilloscope on the central pin of the connector is not present the "1-WIRE" signal, but I see only one level of 3V with pulse-off very short every 1 second and only for a few seconds. In the BIOS mask is not recognizing the charger. If I link the same charger in another Dell notebook is recognized and is displayed with the oscilloscope quick burst of data, after the battery starts to charge. I do not have the wiring diagram of the motherboard but I have followed the signal "1 WIRE" and perhaps enters in LPC47N254-AAQ. Should I replace it or can be another problem? 3 K4 j% L/ } E1 t7 N
