MacBook Pro 17 2009 - 820 2610 - No Power

HI all. Looking for a list of components to check on the logic board of a MacBook Pro 17 2009 820 2610 that has No Power problem but Green Light on MagSafe.

I already checked infamous C7771 capacitor and i have 1.1 V.

Also on C7292 I have 3.3 V.

Is there a easy list of components to look at without have to deal with the schematics?

Thanks

the schematics are easy, if you cant handle them you shouldnt be working on the board. Try the power button jumper

Ciao , thank you for your reply !

I have a similar problem But no green light at all !

Checking on in this days... but I’m following a very instructive videos on youtube !

As much as you can try to follow the logic-board , I did silly mistakes in the past !

At this moment checking again with a big lens ? ! Replace C7771 ( was 0,3 V ) now fine but not power on, no G light still !

Please keep us updated

Thank you

@netquik This is the link to the video ( sorry guys it is in Italian: https://m.youtube.com/watch?v=GJS5TFsQOl...

This is for your board: https://www.informaticanapoli.it/downloa...

Be very careful please as you mention U7000 alias ISL6258 or ISL6259 They are not compatible! As you can read here: https://logi.wiki/index.php/ISL6258_ISL6...

take care
