Everything functioned properly before heading to the grocery store. My mouse, keyboard, and TV turned off, and I left them on. After returning, I turned them back on; the TV displayed for about 10 seconds and behaved similarly to a MacBook sleeping. The TV recognized when I unplugged the HDMI and showed a different message. Pressing the keyboard keys or clicking the mouse would wake the computer for roughly 10 seconds. The system operated normally with the screen visible once I opened the lid. Using the latest MacOS 12 version, I tested a budget USBC dock and a Type C to HDMI adapter. The keyboard connected via Bluetooth, while the mouse worked with a Logitech MC anywhere 3 using a USB receiver. After restarting, this configuration remained stable for several months.
They seem to enjoy sleep cycle experiments using magnets. It’s possible the magnets weren’t fully demagnetized, and the Mac still feels like it’s saying “I’m asleep.” That sounds pretty unlikely. I’m not sure if the device would have been updated while you were gone.
It suddenly began functioning. I’m not sure what’s happening. I’ve seen this strange behavior before—sometimes I just didn’t want to charge it, and I’d have to reset the SMC.
Suddenly getting up and dancing might seem odd, but it’s just how I feel about this laptop. The analog issues point to soldering problems. I’ve dealt with Apple laptops before—those huge barrel connectors often fail when the female end gets damaged by a simple bump. I had to re-solder it several times. Maybe an Apple engineer would have a better idea. They see these kinds of failures all the time.
The magnets are quite effective. They work not just on Mac laptops but also on non-Mac ones. I had a situation where my fiancé’s non-Mac laptop would unexpectedly enter sleep mode. While at work, I couldn’t observe the details. It turned out she discovered the perfect spot to place her phone and trigger the shutdown. It seems the magnet used by the device detected when it was closed. The Apple MagSafe technology is powerful enough to cause this effect.
If the magnet is dislodged, using glue instead of solder makes sense. It looks like the part needs to be separated for repair. A big hassle, but manageable. These components are typically found in the hinge.
I have Apple Care coverage until May 2023. If there’s a problem, I’ll arrange for repairs. Currently, everything appears to function properly. Additionally, I’m concerned the magnet might detach if the device remains stationary and stays in clamshell mode.
