MacBook Pro 13 (2020) · Charges on and off · Sample passport RT–001

The history is missing.
Without the repair history, Retrace only has the symptom to go on, so it suggests the most common cause. It has no idea a battery was already tried.
Check first: Read battery health and cycle count; run on AC with the battery removed.
This is a suggestion for what to check first. A technician should look at the laptop before anything gets replaced.
What’s in the record?
- Charging problem reported
“It only charges some of the time.”

What was learned
stays with the laptop.
Each result you record changes what Retrace suggests next. When the laptop is sold, the buyer gets all of it.
In this example the switch between owners happens in your browser. For a real laptop, Retrace asks Sui who owns it, through Tatum, before showing any history. The records themselves come from Walrus Memory.
