Ideas on why keyboard is no longer functional after battery replacemen
I opened my laptop to find that my battery was grossly swollen. Apple had replaced the battery years ago and wouldn’t do it again (plus the pandemic). I decided to handle it myself after reading the guide. Got my new battery and repair tool kit and got to work. Teardown was tedious but doable. The battery came out surprisingly straightforward. Checked out the condition of everything and no obvious damage to anything. Installed the new battery and reassembled the laptop. Plugged into power supply and allowed for a full charge + 2 hours. Booted and all appeared fine. However, no response from any key except the power on button. Keyboard backlighting works fine, trackpad works fine. All other functions work fine. Got out my BT keyboard and no issue typing there (using the laptop and BT keyboard to type this). Reseated keyboard data cable several times. No joy. Removed and reseated trackpad cable. No joy. The laptop is fully functional except for the keyboard. Performed the SMC reset for this model, however, if the keyboard is not functioning then I can’t see how the procedure for resetting the SMC would work because it relies on the keyboard working. No joy. Anyone out there got any ideas? Thanks in advance for any assistance.
