Step 1Question
What colour is the charge light?
We're doing this to find out whether the charger is being accepted at all.
Know where toprobe next.
NextProbe asks what you can see, lights the next point on the board, reads your meter and moves on, from a dead board to a confirmed fix.
Try it on the demo board
Three questions about what you can see, then the board lights the next point and a simulated meter does the rest. No account and no download.
Step 1820-00000Open
Reading
Waiting for a reading
C7010 has failed short across PPBUS_MAIN, so the bus reads as a dead short in diode mode.

How it works, in three steps
Pick the board
Type the board or model number, or walk brand, line and year. The profile shows the known faults before you open the case.
Pick the board (sample data)
Board number, model number or name. Part of a number works: 820-33.
Answer what you can see
Up to three questions: the charge light, the current draw, the fan, the display. Each one is answerable at a glance or by voice.

Follow the lit point
Black lead here, red lead there, the reason why, and the expected range. A steady reading saves itself and the next step loads 2 seconds later.

What every step gives you
Every step says where both leads go Red lead on C7010 pin 1(PPBUS_MAIN) and why. A steady reading saves itself with a verdict In range. Every confirmed fix teaches the next session Seen on this board 31 times.
A fault opens the branch for that rail and an in-range reading closes the branches it rules out, so a session never asks for a reading the last one made pointless.
Readings are stored in base units and shown the way the bench reads them: 0.412 V, 1.2 kΩ, three decimals in diode mode. Every range shows its source and how many samples back it. See how it works in detail
