just recently, i tried charging my ASUS notebook as it had shut down because of low battery, but when I tried charging it, the blue light in the charger doesn't appear, and if it does, after about fifteen minutes before trying again, it just lasts about five seconds and the orange light that means the laptop is charging isn't flashing at all! I searched google, and the results was that I'd take my battery out, but i can't locate it, so help!!
