Re: Acer one KAV60 bios needed

Hi, pin 3 is the +3VALW and pin 4 is the ON/OFFBTN#. On the board you could have a diode who is open, follow the trace from the switch to pin 4, you should have 3.3V on the switch also.

Re: Acer one KAV60 bios needed

I checked on the switch pin 3 have 3.3v but pin 4 have 17.42v

Re: Acer one KAV60 bios needed

When you push the switch, does the 3.3V on the switch go to zero?

Re: Acer one KAV60 bios needed

on the connector on pin 3 have 3.3v when press power button 3.3v on not goes to zero.on power button no 3.3v

i have attached the image on the switch

Re: Acer one KAV60 bios needed

There you go, if you don't have 3.3V on the power button, it will not work. Follow the path from the switch to one of the chips, the chip could be open.

Re: Acer one KAV60 bios needed

the one the chips on the power button?

Re: Acer one KAV60 bios needed

pin 4 is connected on this chip on power switch but still the same voltage 17.42

Re: Acer one KAV60 bios needed

You have to follow the path from the switch to one of the chips, not the ribbon cable to the chip, you have to find out why you do not have 3.3v on the switch.

Re: Acer one KAV60 bios needed

When you find which one, you should have 3.3V on the other pin of this chip.

Re: Acer one KAV60 bios needed

This chip has no continnuity kn the power button and the 1st pin have 17.42 the ontgrr pin has 0v

Re: Acer one KAV60 bios needed

What about the other chip?

[String2016]

Re: Acer one KAV60 bios needed

The other chip the second one continuity connected to pin3 and pin 2and 3 of the chip has 3.3v

[JaroTech]

Re: Acer one KAV60 bios needed

What about the voltage of the other pins? Is the third pin of this chip connected to the switch?

[JaroTech]

Re: Acer one KAV60 bios needed

To be sure, on your picture of the board, write down all the voltages of both chips and the flat cable.
