Found a defective CB300 chip and removed it removing the problem I was facing, looking to identify the chip to order a new one.
It's an 820-00239 I've circled the chip in the photo hopefully it's zoomable (it's small)

Is it CB300? Or CB308 (which is the one you circled)? CB300 is the one under the little tab in the photo. And that sucker is a magnet for a tiny bit of liquid damage.
Ultimately it doesn't really matter because it looks like both of the components in question are 10μF, 6.3V ceramic capacitors in a 0402 package. Realistically, it is not entirely necessary to replace this capacitor. It may have some minor effect on the longevity of the unit, but if that was the fault, the computer should work just fine without it. Replace it if you are able to do so safely.
这个答案有帮助吗？
Thanks for help! it's the CB308 as circled, I was mistakenly referring to it as the CB300.
@Rich Kent No worries, just wanted to make sure I was in the right neighborhood! Happy fixing!
