Hello there, 

Hoping someone can help me confirm the source of an issue I am having with my Acer AN515-51-71LP (Model N17C1). 

Device has been working fine, but all of a sudden this morning it would not power on. Assuming it was a charging issue, plugged into the charger. No lights. When power button is pressed and held, the "POWER" indicator light turns on. Device does not attempt to boot (no fans, no beeps, nothing). I did a power drain in several different manners (removed battery, held power button 30s, wait 5 minutes, plug charger back in THEN battery. Did similar procedure using the button on the motherboard) to no avail. Same issue. 

So, I pulled out the multimeter. Confirmed that charger is putting out 19V. Tested charger at the motherboard - it appears to be delivering 19V to the board. So I tested the battery. 0.00V. I thought "great, battery replacement is easy." However, I then realized that the laptop should be powering on without the battery so long as the charger is plugged in and power is getting to the board (which it appears to be). It does not appear to be the power button itself, so the only thing that I can think of is possibly an issue with the motherboard (specifically, circuitry that receives/interprets/transforms the 19V incoming power), OR this device is an odd duck out - the battery really is dead and, for whatever reason, it won't turn on unless battery is detected. 

I'm hoping that someone with a little more expertise on this particular product may be able to shed some light. Does the battery need to be installed and have some voltage detected in order for the device to power on at all? Or, is there a component I can test to see if it's a simple issue associated with the incoming power? Or, am I screwed and it's the motherboard and I need a new laptop?

EDIT: I did already try removing the RAM sticks one at a time. Same symptoms.

    UPDATE: I just noticed that the "CHARGING" light is solid blue if I unplug/plug back in the charger. However, when I press the "ON" button, the light goes out. It does not turn back on unless I unplug the charger and plug it back in OR if I HOLD the "ON" button for a length of time. 

    Not sure if this is relevant or helps.

    I did read that you need to battery plugged in while i was researching my laptop not so long ago but memory is vague....laptop doesnt run on 19v, battery requires a higher charging voltage to take a charge so im thinking the system is preventing it to turn on as the operating voltage and amps is too high from the charger for the operating system of the laptop.

    like a cars operating voltage is 12 volts but the alternater output 14.2Vs so it can charge the battery. Same would apply here as is DC electronics.

    try googling some more or order a replacement ebay cheapy
