Hi there,
I had this board laying around but I got a chance to get a laptop to test it.
First thing I noticed, the laptop turns on immediately after plugging the adapter in.
I tested it with a known good Nvidia card, good ram and cpu.
First question I have is what can cause this behaviour? ITE EC chip needs reprogramming? Bad BGA chipset? missing clock signals?
Can someone with more experience share some knowledge on this type of behaviour and approach for troubleshoot it?
I measured some signals with the board powered, 19v,3.3V , 5v, 1.05v 1.35v cpu,vga all tensions seem to be present.
The laptop turns on when DC in connected, no image, and fans starts full speed 15 secs after. No reaction at all. dead.
Made visual inspection of the board, everything seems good EXCEPT the chipset that has a light crack on the die.
Would this be possibly the culprit? Anyone had similar stuff with other boards?
As if its most likely the culprit, I will not loose any more time with this board, as its not worth it.
This example is more to understand a bit better what can be the reason for a machine that turns on immediately with power connected, and what should be checked.
Thanks for your time!
