I don't know very much about Japanese culture, but I find interesting the differences between Kyoko-Godai's and Asuna/Míraka weddings. The first seems to be like more traditional, being the latter more like a Christian ceremony. Is this related to social class? Or it was just an arbitrary decision from Rumiko-san?
The pictures show bottom left and right flex cables in a trackpad from a Macbook Air M2 2022. The one on the right looks ok to me, but the one on the left has something weird between the tracks. Do you think this can be liquid traces?
This macbook was peed by a cat, but I couldn't find liquid spill traces on any PCB. Trackpad and keyboard don't work.
Hi guys,
My cat peed over my macbook air. I dried it with towels inmediatly, turned off, and put it upside down. Also disconnected the battery. Two days after I brought it to an apple authorized repair shop and the verdict was that it boots to macos, but keyboard (complete top case), trackpad and lid angle sensor should be replaced, charging me almost $600. They didn't find any liquid spill traces inside, tough.
Since I studied electronics and I've repaired some laptops (primarly replacing parts), I went on trying to repair it by myself. I confirmed that the logic board, the daughter board and the trackpad doesn't have any liquid traces. I've seen a couple of videos on youtube looking for examples, and I don't see any type of corrosion or burnt components in my laptop, as in those videos.
Things I've tried:
- Disconnected the lid angle sensor since I read somewhere that it disables keyboard/trackpad when laptop is closed (and if it fails it can detect that it is always closed) -> keyboard and trackpad still don't work. Cap key led doesn't turn on
- Thinking that trackpad and keybaord share som data bus, I disconnected the trackpad to see that it is making a short circuit or something -> keyboard doesn't work either
- Disconnected the keyboard and connected the trackpad again -> trackpad doesn't work
I've been thinking on buying a keyboard replacement on aliexpress and connect it to the daughterbord, turn on the computer and see if it works.
What else can I check? Any help is welcomed.
EDIT: I disconnected the interposer/daughterboard, but trackpad still doesn't work. I suppose the failure is in the trackpad itself, or in the logic board. Am I wright?
