[SOLVED] Keyboard half working depending on battery or bending
I bought a second hand macbook with a dead battery being told that any knock off one from hong kong would do it.
Since I received the new battery I discovered that my keyboard stops functioning for keys such as Backspace, the arrows, Caps lock, shifts with the letters still working.
If I put back the old battery it works great, if I leave just the power cable it works half and if I put the new battery just the letters work.
Finally If I put the old battery and hold the mac from a corner I get the same result as for the new battery.
Could that come from the keyboard/touchpad ribbon disconnecting depending on the pressure applied to the case?
