Sounds like the cells in the battery have gone down. This can happen with new (although not as often) and old batteries at any time. Have you tried a replacement battery? A GOOD aftermarket battery is not expensive. Or have you tried speaking with Asus in regards to the warranty? (if not expired)
yes i have registered for a onsite visit, the tech guy told me that he will visit with the new batteries.
but what does that bulb icon indicator means ?? its continuously glowing when laptop is on ,,whether battery is inside or battery removed
