Nitro 5 AN515-55 not Charging!!

LalaKhan

When I plug in the charger and

1. The Laptop is powered off:
The orange LED turns ON for 5-10 sec and after that it starts blinking and stuttering randomly.
Sometimes the Blue LED also starts blinking with the orange one.

2. When I turn on the laptop (charge 0%):
The laptop turns ON and give me a critical battery error. And then turns off. During that time the blue and the orange LEDs both blinks at a fixed rate of 1blink per second (not randomly)

How this may have happened: The extension that I was using had a loose connection which may have turned the charger ON OFF rapidly and the laptop is now not charging. 

There is no official acer service center in my country. So for repairs my option is either to take it to a laptop repair shop where they might experiment on it. But luckily I am an electronic engineer.

Here is what I have tried:
1. Software battery reset by holding the power button for 20+ seconds and then waiting for 20mins. This model does not have hardware reset.
2. Charger voltage reads 19.5V
3. Our mains voltage is 245Vrms. Could that cause an issue? The charger is providing the desired output though.
4. Opened the laptop and disconnected and reconnected the battery cable.
5. Disconnected the battery cable and turned ON the laptop with AC power only. (Turned ON for half a second and then turned off)

I am really sorry for the inconvenience..   Let us do the basic steps first..

Doing the power drain and bios defaults will really help.  Kindly follow the steps given below:

Turn off the laptop. Disconnect or unplug  the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, you can find a  pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and - sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer.  Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.

If you dont find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery.  Turn off the laptop. Disconnect or unplug  the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door.  Just below that you can find a latch.  If you move the latch you can remove the battery door. Once the battery is removed,  flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 

 

If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt ) then please unplug all the cables and devices out of laptop.   Hold the power button for 1 minute.   Connect all the cables back and restart the computer.  

While turning on the computer, tap f2. It  will go to bios. Press f9  once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear.  Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.   

 

It might also be the issue with battery, charger or power outlet.   Try to use the charger in a different room on a different power outlet.  Try to bypass the surge protector and connect it directly to power outlet.    Try to use an alternative charger if possible.    Try to turn on the computer without the charger and check it  ( as long as the battery is not drained out )  

Try windows x 

go to device manager 
expand Battery
right click on all the items below battery - uninstall 
Restart the computer 

 

It should work fine..
