Asus N53SN battery indicator blinking green and light

[danniel05]

Hi everybody. I don't think its a new question but as i checked the forum i couldn't fix the problem with my laptop.
It's been a month that i have problem with my asus n53sn
Whenever i Plug in the laptop and battery is charging i see a blinking led from battery indicator.
I replaced the battery with a new one and same problem happened.
I checked my old power adapter voltage and a new adapter and both were giving 19 voltage.
**This problem fixes only when you unplug battery while system is running( of course plugged into adapter ).

And by the way, when the blinking problem happened a month ago, my wireless adapter keeps disabling by itself .. donno why. I'm connecting via Lan cable to internet now.
I have tested all of the above mentioned in win7, 8 and 10.
nothing changed. Same problem

Can anyone help me out plz.
I really appreciate it

It could be the port where the charger plugs in.

Hey there danniel. Does either battery actually charge and discharge? If not, it's probably a problem with the main circuit board.

Well thanks for the answer. When the battery charges at 100% i turn off the laptop. I unplug the adapter and after 2 hours when i want to turn on the laptop i see that it won't turn on. The battery is fully discharged that i have to plug in AC Adapter. When the windows runs battery indicator shows 1% battery ...
Actually this problem occurs to both batteries that i have .. no difference

Well i can use the laptop easily without any problem through AC Adapter port without battery .. but i still have issues with Wireless Card that keeps disabling. Could it be the problem? I will try that . Thanks by the way

If the battery is saying it is full but then then showing dead right away like that, and the device won't power up while on battery alone, I would say you need a new battery.

Happy to try to help.

You're sure the laptop is actually being powered off, and isn't in sleep mode? (But that's still draining the battery egregiously fast.)

Unless you drew a short straw and got a second bad battery (or a cheaper, aftermarket battery), you may have a problem with the laptop's main board. Double check the terminals, if you can (the gold pins where the battery connects) and make sure no problems there. This could be an issue with a circuit that you won't be able to see.
