by mferna14Hi, my dear friends., Maybe this might be a stupid question or something I missed or do not know. I have 2 MacBook Air A2681 (Indentical color & EMC #), both LCD screens broken. Before ordering the LCD Screens I confirmed both worked with their respective batteries & AC Adapters, & they did 100%. The LCD Screens came in today & I replaced LCD for the 1st A2681. (Removed Battery Terminal cable for both Laptops before installation of LCDs). Perfect Screen & Booted up fine. But it did not work with battery. I checked the battery connector & it was seated in well/perfectly....

A2681 turns on but not trackpad or keyboard feedback (or external keyboard and mouse) and then after a minute or so the Mac sleeps..
It's a NOT a sleep sensor or trackpad or keyboard or daughterboard or anything else (I replaced all those); it's the logic board..

by Jamey021So, what are the odds I shorted the M2 CPU? I got in an a2681 MacBook Air. Liquid damage. Ordered from China and replaced a chip (APL109D 343S00555) cleaned corosion and ultrasonic..The whole 9 yards.
Last night I put it all together and it came on beautifully. 20V- Apple Logo. I celebrated and knocked the LCD connector loose right away while holding the laptop. Now, it wont boot and it cycles on the volt meter.
Cycle 20v - .02a then volt meter goes off, then it comes on and rinse and repeat. Classic sign of a MacBook short. I looked at the board with my thermal camera and I can...01-22-2025, 05:22 AM - Loading...
