Why is the power button not working?
After a digitizer and wifi chip replacement my power button and i also think volume stopped working?
GSM iPad 2 with 16, 32, or 64 GB of storage, and a Dual Core A5 Processor. Model Number A1396. Repair is complicated and requires heat and prying.
The iPad 2 has a ribbon cable in the top-right corner that’s responsible for the power button, volume, and mute slider functionality. This ribbon is frequently stuck to the digitizer, and is easily torn if you don’t know it’s there, and don’t take active measures to gently seperate said cable form the digitizer during repair.
Edit: Yes it’s a hardware problem.
