[SOLVED]820-2523 not charging

[dukefawks]

Original issue is Q7055. Replace ISL again.

replaced isl now im not getting pm_slp_s4l board will not turn on.

I cannot see over the internet what you have broken....Is PPBUS still present?

 

[Gmorb]

yes its there at 8.16v

 

[dukefawks]

And what does a low PPBUS voltage like that mean?

 

[Gmorb]

ohh too low.

 

[Gmorb]

ok got the machine working again but it wont charge. charger light slightly pulses while connected. 17/18 - 27/28 of u7000 are giving proper readings.

 

[dukefawks]

What is PPBUS then without a battery?

 

[Gmorb]

8.19v without and pulsing 11-11.20v with battery connected

 

[dukefawks]

Did you replace the ISL with a 6258? This is not a 6259! If that is correct check voltages at Q7065.

 

[Gmorb]

Switched out the isl for a 6258 now its back to charging normally!
