Right guys, time to fix my personal laptop. something i have not really looked at in depth yet.

Before someone says 'keyboard power button' Its not. It also runs of battery just fine.
Does an SMC reset, but if i turn it of its dead again till i plug it into a charger. Something around the SMC not right maybe?

u5010 and associated components replaced due to damage there prior.

U5750 replaced, no change in symtoms, ill look at it in the future, bet its something iffy to do with the SMC i fitted to this board long ago (or maybe the KBC).

Tested the keyboard with another board and it doesn't have the same symptoms.

i will get the battery information in just a moment however im not sure that would cause an SMC reset, i believe it still SMC resets like this when the battery is unplugged.

So as soon as you hit the power button the light turns green? Check if SMC_RESET goes low if you hit the power button.
