Aspire A515-51 won't turn on - only blue light on random key

Hi,

my Aspire A515-51 suddenly turned itself off while i was using it. After that moment only this strange thing happen:

If i try to turn it back on with the power button, no effect (no blue light on the led… nothing)

If i press a random key on the keyboard it the blue led turns on, the screen backlight turn on, the pc starts booting… but after a couple of seconds (i never go past the "acer" logo on the screen) it turns back off.

So far i have tried:

Pressing the battery reset button for many seconds, no change
removing the RAM, no change
Removing the ssd, no change
disconnecting the internal battery and the cmos, no change

Any idea on what could have happened?

Thank you in advance

This is a 2018 laptop and if the battery was never replaced it may have died after 6 years. Replace the battery and if the LEDs still won't turn on replace the power adapter as well.

Thank you for the suggestions:

I tried to replace the power adapter and nothing changed. I have no new battery to test it, but shouldn't it turn on if attached to the AC, even if the battery had died?
