820-00928 - Damaged Component

Hello,

Thank you for your help today! I was tinkering with a trashed 2017 15" MBP i7 2.8GHz 256GB Radeon 555 and I accidentally popped off a component.

In my research, I found the schematics for the board and I think I can identify it as C7052 / PPVBAT_G3H_CHGR_REG.

I have pointed to it with a red arrow (and red box) in the image attached.

The unit still powers on - and I don't notice any issues. However, how "dangerous" might it be to run the machine without this? Is this something that can be replaced?

Thanks!

First of all, welcome to the forum!

You can find it even on old MacBook boards (many models).
68uF/16V, just look for one similar in size (D2E_SM).
Not very difficult to replace it.
Apply leaded solder and remove it heating and lifting one side first.
Even more easy to resolder it; practice on scrap board.
Do NOT use hot air.

Machine can work without it.
However, may be noted when runing on max specs.
