Hello.
Have this lenovo that customer sais was sutted down during diagnostic app and start without video. but when it gets to me it looks like IC for ALW power is keep restarting. The ALW 3,3 and 5V rail goes up for a half a second and again after few seconds. Dont have schematic as i see it is not awailable
when it not give ALW it board consume 0.49W and when ALW works it consume 0.13W which is normal consume
i found that i have enable signal for just half of second. vreg voltages is ok and steady
after few klicks on "novo" button board start for two seconds and ALW miracle stays on for about ten second and than does down again
