Hi this laptop had liquid damage: I found a couple of burned contacts on the keyboard connector, and it worked for a while after I cleaned them. After that, the keyboard stopped working completely I replaced the sfp connector and still the same. I doubt the problem is the keyboard, as it was working ok until it stopped completely. I suspect either a DC line is broken or there is a fuse failure.
if I get an schematic I will check.
There are several compatible boards, the models are: 827824 , 827823 , 809842 depending of the installed CPU
Alternatively, if somebody can confirm...
