    @ mothcollector,
    The keyboard is part of the top case. In order to replace the keyboard you will have to separate the metal plate which is riveted to the top case. Is it doable? Yes. Is it easy? Probably not.

    Hello,

    Thank you for the effort that you put into this.
    My model is a Satellite L55-B5276. It keeps losing the time and date in the BIOS. I cannot locate a CMOS/RTC battery. Unless I missed it I didn’t see in your photos either. Can you advise?
    Thank you for your time,
    Robert
