    Superb pictures, really helped me as I have an Acer Aspire E15, E5-523-904B which is not working after rain soaked while plugged in gulp! I’ve tried most things like removing the battery (after seeing how you do it) and plugging in power adapter but still no joy. No led lights showing, also removed hard drive, memory, fan (which was very dirty). I can’t find a cmos battery on the motherboard though, should I have one?. Any help you can offer would be appreciated. An internet site I was on said it might be the power button board/cable. Best wishes Tom

    @ Tom,
    In my example the CMOS battery shown in the step 8. It’s a CR2032 type battery.
