What components are missing from the logic board of this A1466 2017

What are the names and relevant parameters of these electronic components on the logic board of this MacBook Air A1466?

When replacing the components, after removing the electronic components, I can't find the corresponding ones to replace them, nor do I know their relevant parameters.

Here are the pictures before removing the components:

Here are the pictures after removing the components (three positions marked

Here are the three marked components:

Here is the overall picture:

Additionally, when testing these marked electronic components with the continuity/resistance mode of a multimeter, there is a constant beep. Are these electronic components faulty? Among them, all electronic components in two positions are beeping continuously.

@libai73344 the components you are inquiring about are as follows:

Reference designator U7090 is a LT3470AED Buck regulator. Here is the LT3470A datasheet

Reference designator R7096 is a 200K ohm 1% 1/20W resistor in a 0201 package

Reference designator R7080 is a 0 ohm 5% 1/20W resistor in a 0201 package

Parts are available at Mouser.com Digikey.com as well as many other places.

All the parts that are showing continuity with your multimeter are capacitors. Yes, they do need to show continuity. You would need to measure capacitance or short to ground but not continuity or resistance to determine their condition.

@libai73344 seems like everybody has the schematic but not the boardview file. You can download it from here from here and of course another copy of the schematic. To view he boardview use the Boardviewer 2.0.19 or above from here.Let us know if you have any issues with that. Also, let me know when you have downloaded those files, since I do not need more traffic on my drive :-)

To start things you really need to review the schematics and board view drawings to properly identify the components and what signals to expect. Mostly we work with voltages not continuity and when in doubt resistance.

Here's the schematic Schematic Macbook J113 82000165 05100385 my copy of the board view is damaged I suspect the newer viewer I have doesn't like it. Look online for 820-00165 which is the boards ID used in both the 2015 & 2017 models as you need to reference it for the location and the chips ID to then locate in the Schematic view to then know what the signals that are expected.
