    It may be a failed update, but the LEDs not showing is indicating a Power failure. When did you replace the battery? If you are not worried about losing the Acer warranty open the laptop and disconnect the battery cable from the MOBO, take out the CMOS coin battery and shorten the +/- contacts inside the CMOS housing. Replace the coin battery with the + sign up and close the CMOS housing. Press the Keyboard Power Button for a full minute and check the DDR4 RAM modules if they are seated in the slots properly, reseat if necessary. Don't reconnect the battery yet but close the back temporarily without the screws and plug-in the adapter, try to boot. If that works, unplug and reconnect the battery cable to the MOBO. Try to boot with battery only, if no luck, try to boot with adapter and battery. If no results you probably have a dead battery.

    But without the battery, it should still work like its plugged in AC or power connection? Does t intefere with the cmos battery too?

  • It would be interesting to inform the model of the computer! Example: AN515-55-5780. Now, if the LEDs are not lighting, check these tips:
    a) Test the output of the power adapter with a multimeter, in the continuous voltage range. Check if 19v or similar is coming out.
    b) try disconnecting and reconnecting the lithium battery.
    c) if the problem persists, then you have a problem with the 3v and 5v primary voltages. They are voltages coming from the primary pwm. Without these voltages, the computer does not turn on and the LEDs do not light up, because they are voltages that have to appear as soon as you connect the battery or the power adapter.

    The laptop will work without battery, and CMOS won't be affected if the bayttery is disconnected, it has its own coin battery inside.
