The problem is the parts are missing from the board I am repairing. If someone had a board like this they could take a closeup picture of the resistor values for me and tell me the value of this missing capacitor
I would greatly appreciate it. I am missing a 603 capacitor and two 603 resistors.

This boardview does not include component values, and without a schematic, we cannot determine them. However, there is one solution: if you cannot find a clear image scan of the board, you can check the datasheet of the chip connected to the resistors to obtain the values or refer to another schematic that uses the same chip model.

According to the schematic, pin 24 is SDA and pin 25 is SCL in the PMBus section.
Solder SDA, SCL, and GND, then connect the programmer to your computer and power on the device.
If you’re using an offline adapter, first solder the chip, then connect the adapter to the programmer before connecting the programmer to your computer.
Software Setup
Open IR PowIRCenter or XDPDesigner, depending on the chip type.
When the programmer connects successfully, the status indicator in the lower-left corner will turn green.
Click the Auto Populate Devices icon (first icon on the left).
All connected chips will be displayed under Total Pout (e.g., IR35217, IR3580 if both are connected).
Select the desired chip from the list to display its register map, where you can view and modify parameters.
Backing Up the Program
To back up the current program, click Save Config File.
If a user password prompt appears, simply ignore it and click Continue.
The file will be saved in .txt format, which you can use later.
Alternatively, you can save the entire board data by clicking File > Save Board Design, which generates a PCB data file.
Writing a Program
To write a configuration, click Load Config File and select the desired .txt file.
Then click Write All Reg to program the chip.
Utilities & Diagnostics
The software also offers several utilities under the Utilities menu.
For example, selecting SalemDevice will display a counter showing how many times the chip has been programmed (some chips have a write limit).
Clicking Check MTP will reveal additional memory/programming details.
Selecting Device Status will display a phase fault report to help diagnose potential hardware damage.

Inductor Motherboard Tester, Detect Inductance & Coil Activity – Diagnose Dead Rails in Seconds!
Inductor Handheld EMF Pulse Inductor Tester for Laptop Motherboard Repair
This compact diagnostic tool is designed to detect high-frequency electromagnetic pulses emitted by PWM coils on laptop motherboards. It allows technicians to quickly identify switching activity in critical power rails—such as CPU, GPU,POWER SYSTEM or charging circuits, without the need for pulse trigger test with oscilloscope.
Simply place the tester near a motherboard inductor; if switching pulses are present, the onboard Green LED will turn on. This makes it an essential tool for diagnosing issues like dead CPU rails, shorted VRMs, or missing gate drive signals during board-level repair.
Detect Missing Switching on Key Power Rails
Identify inactive S5, S0, VCORE, or VCCGT rails with ease.
Pinpoint Faulty Components
Helps locate issues such as open coils, circuit bad MOSFET drivers, or failing PWM controllers.
High-Frequency EMF Detection
Sensitive to switching frequencies from 100 kHz up to several MHz.
Instant Visual Feedback
LED indicator on when switching pulses are detected.
Specs:
Power: CR2032 coin cell ( not included )
Indicator: Red LED for for POWER & Green LED for pulse detection
Trigger range: 100 kHz – 5 MHz
Size: Compact and fits any technician’s toolkit

DDR5 LAPTOP TESTER FOR Motherboard Detect the CPU Short or Open And Slot tester with Light Detection
DDR5 Laptop Motherboard Tester
Quickly detects CPU shorts, open lines, and DDR5 slot faults.
LED indicators show fault status—off for open line, extra bright for short.
Test points like BULK,ALERT,HSA,RESET, HSDA, HSCL،POWER GOOD can be measured online.
Pin reference guide on the back for easy troubleshooting.
DDR5 Laptop Motherboard Tester – Detects CPU Short or Open Circuit & Slot Status via Light Indicator
How It Works:
Open Line (No Connection): The LED remains off, indicating a possible fault in the DDR5 slot or the CPU—this may also suggest the CPU requires reballing.
Short Circuit Line : The LED will glow brighter than the others, signaling a short in the slot or CPU area.
Important Test Points:
For advanced diagnostics, you can remove the tester’s battery (cr2032) and power on the laptop to measure key signals directly from the test points, including:
Easily Detect CPU Reset Signal:
The tester allows for quick and easy detection of the reset signal coming from the CPU, helping you verify whether the processor is initializing properly.
LED Indicator Pin Reference:
If any LED shows abnormal behavior, you can identify the corresponding pin number by checking the label on the back of the tester. This allows for easier troubleshooting of specific signal lines or faults.
