🎯 The Client’s Request
A client submitted a MacBook Pro (13-inch, M1, 2020) due to multiple unresponsive keys following a liquid spill. They specifically requested an “only keyboard change” to minimize cost. The critical need was speed, as the client’s work depends on the machine’s reliable function.

🔍 Technical Diagnosis
For the MacBook Pro M1 (2020), the keyboard is permanently riveted to the aluminum upper chassis (the Top Case). Attempting to replace the keyboard component alone is time-consuming, risky, and unreliable.

Our professional diagnosis confirmed that the most efficient and warrantied solution is replacing the entire Top Case assembly, which includes a new keyboard, trackpad, and fresh battery. This approach guarantees the full resolution of the failure.

✅ Execution: Top Case Replacement
Data Secure: Full data integrity check and backup.

Disassembly: Careful transfer of core components (logic board, display, etc.) from the damaged chassis.

Reassembly: Installation into a genuine, new Top Case assembly.

Testing: Comprehensive function and battery calibration.

📈 Outcome
The laptop was repaired and returned fully operational in under 36 hours. The client received a reliable, like-new typing experience, plus the added benefit of a new 100% capacity battery. The key takeaway is clear: for this model, the Top Case replacement is the only professional way to guarantee a reliable keyboard fix.
