No liquid damage whatsoever I replaced the battery following the iFixIt guide for Apple MacBook Pro 13’ A1708 Battery replacement. After booting up it seemed totally fine until I tried typing in my password and had no responses from any of the keys. Checked keyboard and trackpad ribbons and reseated themRestarted, checked every key if any of them worked but only the power button is responsiveBattery is good and trackpad is responding. Any thoughts or suggestions?
Are you sure the uppercase ribbon cable (which connects the keyboard & touchpad to the logic board) is not damaged or the latches are in good working order? Unlike the older retina systems the power button lines are part of the TouchID button. If you can ,plug in a wired USB keyboard & mouse. If these work you have a connection failure between the internal to the logic board.
