        well ok back to this machine sorry for the big delay , well , KBC was damaged since the dc jack light was not working even after bios replacement since the original was empty !!!
        so with new KBC , dc jack leds turn up , machine turns on , but NO IMAGE """!!!
        another things i tryed with some outher dumps even some slicks gave by spider and dycc in outher post , but even does , not working , still turning on but no image ,

        no another thing i noticed , once i insert the battery the dc jack led dont turn on and machine also dont turn , only can notice a very tiny flicker from the dc jack led ,
        bad new KBC ???
        all feedback will be welcome .
        btw replaced the charger ic as well , but same issue .

                As I red the whole thread I'll like to ask about the first repair attempt with the replacement of kbc it8528e.
                The question is general.
                A lot of times I have issues with systems that don't power on, some of the have shorted kbc. I replace the kbc with new one and make sure I have working ec and bios but they don't power on. I have the signal from power button coming into the kbc but nothing happens.
                So the question is that these new kbc need programming?
                I have seen some programmers for IT series kbc, are there and configurations for them also?

                  ITe are not common to keyboard line programming ! usually more into certain ENE modules.

                  actually for my experience , on this board , they got more problems on certain regulator than that on the kbc , usually charger problems , bios , problems , short on some regulator , and yes soemthimes kbc its envolved , well electronics can be a pain in the ass , but following schematic will drive you thru the problem and you'll find pratically always an option and a figure it out way
