820-3115 running slow

[pcfriends]

attempts 4 5 6 7 : fail

I will keep trying tomorrow

 

[pcfriends]

thank you man im waiting for another smc and then I wil retry

 

[larossmann]

just buy five or ten of them and figure it out. stop using the word fail, it just didn't work that one time. it will work the next one.

hey I change SMC once more , and now machine turn on again , and I have green light and orange , I run as and now I only have 1 bad sensor TA0P all the others show ok , how I can diference witch one is it?

 

[larossmann]

Can you remind me the full name of it? It usually says fin stack sensor, proximity sensor, pbus voltage sense, etc. TA0P what? I don't know it off the top of my head. I am guessing it is one of the sensors near U5511

 

[dukefawks]

I believe this is Q5520, check around that area. Is it reading high or low?

 

[pcfriends]

ambient air sensor

 

[dukefawks]

It is also possible you used an SMC from a different board, you sure it came from 3115?

 

[pcfriends]

damn Im not sure ebay seller said 3115

 

[pcfriends]

hello masters for q5520 on pin number 3 I have 1v , for pin #2 I have .60v , for pin #1 I have 1v , also on diode test I read .751 on all the pins , I should replace it?

 

[dukefawks]

What is the sensor reading? Check hardware profile in ASD.

 

[pcfriends]

location: TA0P -124 c type temperature , description : airflow temp

 

[pcfriends]

How I can find out the name of TA0P on the schematic ? or any other sensor ? where is a guide to understand the asd names to match them on the schematic ? , and what should be my next step?

 

[dukefawks]

-124 means nothing is connected to the sensor. You can bridge the 2 sense wires together and I think it will read 8C or something, try if it reacts to that.
There is no way to find the exact sensor. Some diagrams have them listed and you need to figure out what they are on another diagram.
I still think bad solder on U5511 or dead Q5520. Or we are looking at the wrong sensor, you can remove Q5520 and see if an extra error pops up.

 

[pcfriends]

hello master duke I remove q5520 and guess what? and extra error sensor show up on as q5520 is Th1H Fin stack wtf? then where is the TA0P?

 

[pcfriends]

im afraid I didn't explain right , I remove q5520 and on asd another sensor error show up Th1H Fin stack , so q5520 is not TA0P

 

[pcfriends]

Q5515 is TM0P memory proximity I remove it and try test , so any idea where I can find the name for TA0P?
