Nitro 5 AN515-55 not turning on and no battery light indicator

Hello everyone,

I have an Acer Nitro 5 AN515-55 that turned off while using it and the battery light indicator doesn't turn on when the charger is plugged in. The charger works. That has happened few weeks ago and it still doesn't turn on.

I have tried holding the power button for a minute and then waiting a couple of hours and plugging back the charger. There is no pinhole at the bottom of the laptop. I have also removed the bottom panel and disconnected the main battery (which was hard to unplug, hopefully there wasn't any damage done) and then reconnecting it again.

The computer was purchased and being used since mid 2020.

Help would be much appreciated at least to know what are the possibilities to cause such a behaviour. Thank you all in advance!

    Do the disconnecting of the battery again, on the motherboard side, that cable connector should be very tight, use your finger nails only to pull it out Next is to press uninterrupted the Power Button for 2 minutes at least (you did not mention that above) to discharge any statics. Go slow and be patient with these procedures, wait a few minutes between each action. Don't connect the battery yet but see if the laptop will start only with the adapter plugged in, without battery. If that works you may have a bad battery (or your laptop model won't work without battery). Then shutdown, unplug the adapter and connect the battery, close the back cover and try to start first on battery only and if that works with the power adapter plugged in.

    In addition to the above, you need to do a Hard Reset, which entails disconnecting the main battery, disconnecting the bios battery and take the ram out, leave all components disconnected for 30min then reconnect all components back, as this resets the Super IO and BIOS chips if they are forzenwith the ram and if you have 2x ram modules, only connect 1x ram module and then see if both lights are on the right side of the laptop then press the power button to boot your laptop and see if your laptop boots.

    If that doesn’t do anything then you have an internal problems within your AN515-55 laptops circuitries in the laptops primary power stages, like a burned out resistor, capacitor or at worse and you should hope that its NOT a mosat that regulates power to the VCORE, as that is a critical fault that can burn out your CPU and it happens very often with laptops and you need to replace the mobo. All this has to be checked out or you can inspect the laptop yourself for any burned out components at the power port if they are not burned out. Have a look at this youtube clip of the problem that I’m talking about here “Another 17R4 Dell Alienware Short circuit Repair - Will I win this time ?” as this could be the fault that you could have with your laptop if the Hard Reset doesn’t work.

    Hello,

    Thank you guys for the responses. I did everything that Puraw recommended with no success.

    So I took the laptop to professionals and they told me due to overheating the cpu is dead. How is this even possible… Isn't there a protection against this?! This is very saddening

    Thank you for the update. I was having the exact same issue (turned off while using it and the battery light indicator doesn't turn on when the charger is plugged in) and I find this post during searching. Now I'm suspecting dead CPU is also the cause of my computer suddenly not booting.

    This specific model has a very poor cooling design. As a matter of fact, I have been living with 85+ Celsius CPU temp (even easily 90+) when IDLING for quite some time. Of course I have cleaned the fans as best as I could, and have redone all the thermal paste. But it is just simply design failure, especially for CPU compared to GPU.

    The other part that I found suffering from overheat was SSD. When overheating (probably over 65 C), the SSD would lock itself at 20 Mbit/s top until it feels cool again. It was very frustrating. Also for quite some time, I have to use a small fan to blow directly at the SSD spot even when downloading or unzipping big files.
