Nitro 5 AN515-54 no power, no charging light, won't turn on.

Hello and thank you for reading -

This Acer AN515-54 stopped powering on and no longer lights up when a power adapter is plugged in, no ability to turn on the machine.
Things I have tried:

1. Did a hard reset of the battery, by disconnecting the battery and charger and then holding power button for over a minute, then plugging in battery or charger one at a time or both.
2. CMOS battery reset
3. Checked power supply and the charging jack on the machine with a multimeter, both read 20v instead of 19.5v mentioned on the machine. But isn't .5 volt close enough? This is the default charger that came with the machine.
4. Checked pins below the charging jack to make sure it also read 20v.
5. Looked at the schematic (for the 515-51, which is the only one that I can find online). It says check to make sure SW2 works on the motherboard, but I cannot locate SW2 on the motherboard of my 54 model. 

Can anyone help with finding the Acer Nitro 5 515-54 schematic or service manual online? This would tell me where SW2 is and then I could test it.

Any other things I can try?

Thank you.

Plebworks my advice to you and I appreciate that you have done all the preliminary troubleshooting that you can do but, your Nitro 5 AN515-54 needs to be diagnosed by an experienced tech that has all the equipment and expertise in micro soldering to fix your power problems, as the charging circuitry inside your laptop has problems e.g. mosfet, resistors, capacitors etc that are burned out and need replacing and fixing. Btw, have a look at Alex who’s the best at this and many more fixes at NorthridgeFix and one of his many fixes of the type of power and not charging that he fixes of a “Dell Latitude 7490 Laptop No Power Not Charging Motherboard Repair” or at Electronics repair school “Dead laptop no power not charging? You can fix it!” who all diagnose and fix many of your problems.

Plebworks,

Are you getting any light indication when charger is connected.
