Re: Dell Inspiron 5010

on the block diagram shows that you need +3.3V_RUN and you need to see SCL and SDA

Re: Dell Inspiron 5010

Could you post PU5001 voltages of all pins?
And resistance of all pins except pin19 & pin21 (don't touch these cause you may close one of the fets & will get missleading readings)

Also in this one RAM data are processed by CPU via PCI bus...Did you try another CPU???

Re: Dell Inspiron 5010

And do you have 1.5V @ PL5001???
Did you try another CPU?

[innocentforeign]

Re: Dell Inspiron n5010

pin 4 1.51
pin 8 1.51
pin 20 1.54
pin 23 1.51

at these pins are 1.5v


i don't have same CPU i try to chnage the CPU and infrom you

thank a lot for help ...

[loser18]

Re: Dell Inspiron 5010

a meant PL5001...COIL...

Because I don't like 19 4.24V...
Those fets should be open i think...

[innocentforeign]

Re: Dell Inspiron 5010

yes there are 1.5 v coming

[innocentforeign]

Re: Dell Inspiron 5010
