Diagnosing a Dead 2020 MacBook Air after Liquid Spill
A professional 2020 MacBook Air A2337 liquid damage repair was necessary for this machine (RepairID #2303) after liquid was spilled through the keyboard. The device arrived completely dead and unresponsive. When we connected our USB-C meter, the machine was stuck at 5V and 0 amps. This measurement indicated that the system could not negotiate the 20V power delivery required to boot.

Upon removing the bottom cover, we identified visible oxidation on the trackpad connection to the logic board. We advise against letting a machine stay in this state. As liquid dries, it creates oxidation that progressively damages the internal components. In this case, while the logic board appeared clear, the trackpad area was severely affected.

Addressing Trackpad Oxidation and Short Circuits

Our microscopic inspection revealed bluish-green spots of oxidation on the trackpad daughterboard. We carefully cleaned these areas using high-purity isopropyl alcohol. We discovered that the residue had created a short circuit on the trackpad board, which was pulling down the main power line. This electrical fault prevented the BridgeOS (low-level operating system) from communicating correctly during the boot sequence.
To resolve the issue, we performed precise trace repairs and replaced the failed components on the trackpad circuit. We also added extra insulation to the repaired areas to prevent any future short circuits against the base of the machine. This specialized approach allowed us to save the original hardware rather than performing an unnecessary trackpad replacement.
BridgeOS Corruption and Data Security

After the physical repairs were finished, the initial boot attempt still showed the machine power cycling. This occurs because the BridgeOS—which handles encryption keys—can become corrupted if it detects a short circuit. Furthermore, it can fail if it receives a mismatched signal during its boot cycle. Fortunately, by bypassing the faulty signals and resetting the power sequence, we restored the communication. Most importantly, this method preserved all the customer’s data, which would have been lost if the BridgeOS was permanently corrupted.

Once the trackpad circuit was stabilized, the MacBook immediately negotiated 20V and began pulling a healthy 2-amp charging current. We performed a full hardware test, confirming that every key on the keyboard and all trackpad functions were working perfectly. This case proves that prompt professional treatment can save a “dead” MacBook from permanent failure.
