Help Me to Identify a Part in Macbook Pro Early 2011 Motherboard

[nirmal_kumar]

Dear Friends,
I am facing a strange issue (after using the laptop for more than 10 hours continuously) similar to this thread. https://www.electronicspoint.com/fo...macbook-pro-core-i7-2-0-15-early-2011.273515/

Unable to Poweron the Laptop. Battery is not getting charged but when i hold the power button and plug the magsafe it works. But still battery not getting charged (tested with a new battery also).

I scanned the Motherboard closely and identified a component which seems to be burnt out. Can someone help me to identify this component and whether is this related the to the above issue i am facing? and how easy to replace this component?

Hello,

I can not see the image, as a login is asked for.
Resize the images to about 300 kB and post them in the forum.
You can also use a cropped picture extra with the details.

Hello,

The TXC part is a crystal:

I do not think that is defective.
The parts next to the TXC look eroded:

Yes. You are right. Do you know whats that part for and whether the issue in behaviour of charging is related to this?

Do you know whats that part for

They are part of the oscillator cct

and whether the issue in behaviour of charging is related to this?

maybe, maybe not ... depends where in the scheme of things this oscillator is
without good circuit info, that is pretty much impossible to tell
