MacBook pro, AGND

[lcdcaps1]

I am not sure if this has been asked before but, I will appreciate everyone's help from everyone here

Macbook schematics show gnd and agnd
Upon checking ohm reading from agnd to a screw hole it is connected

One of the cap pads goes to agnd that is ripped, so i was thinking to scrape where the agnd pad and make a ground pad


If I were to connect this cap that goes to agnd to the scraped pad, gnd
what would happen?

But why does the schematic show two grounds but practically they are going to the same place?

Thanks all

Re: MacBook pro, AGND

One will be a digital ground while the other is an analog ground. Granted, they are both ground (well behaved ? - small joke); they are different in the following sense:

Hi
Thanks for your reply to the post
I understand there are two grounds, Analogue and digital
As both grounds are going to the same point would be ok to scrape copper and connect the SMD cap to this ground but this would not be AGND but normal GND

Thanks all
