Re: hp 15-e050sp bios problem

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?

Re: hp 15-e050sp bios problem

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
