hi , laptop have no sign of power .

i have check on con14 pin 7 have 0v.
pin 1 have 3.3v when i push power button 3.3v goes to 0v.



i have check voltage on Max 8770

pin 8 have 19v
pin 19 and 25 have 0v




is it correctly ?
many thanks

Я проверить это con14 у 0В 7.
Есть контактный 3,3, когда я нажимаю кнопку питания идет в 0v 3,3.

У меня есть одна проверить напряжение Макс 8770
есть 8 контактный 19V
вывод 19 и 25 у 0v


Разве это правильно?
большое спасибо

The Max8770 makes power for CPU and starts last of all other power sources.
You mean - the notebook is NO POWER ON?
If so, check another power sources, and reactions MIO (KBC) after pushing the power button (RSMRST#, state of signal S3, S4, S5, powergoods, ect. ).

hi,
laptop is no power on , no light nothing.
i'll look on KBC.

HI can you tell me which pin i have to control on WPC please ?
thank you

1. Check RSMRST# on U51 - must be logic 1.
2. Check NBSWON# (pin 20 on KBC) - signal from power button.
3. Check reactions DNBSWON# (pin 15) on pushing power button. - this signal go to ICH8
4. Check Susb# (pin 14), SusC#(pin 98) - this signals go from ICH to KBC.
5. Check POwergood (pin 108)
6. Check SUSON, MAINON signals - must be after susb#, susc#.

hi,
1 i can't undestand "logic 1" can you explain me more please
2 no signal bettween power button (pin1) and KBC pin20
3 no voltage
4 pin 14 no voltage , pin 98 have 0.02v
5 powergood have 0v

High signal level is usually 3.3 or 5V. There is confusion with active signal level. In this case # says that signal is active when logic level is low, i.e. 0V.

Ok.
RSMRST # (pin 4) on U51 have 0v

i made mistake when i check :
pin 20 of KBC have 3.3v when i put power button voltage go to 0v.
