I have an Asus K501 laptop that I'm trying to determine whether it has a battery issue or just a bad adapter. The computer stays on for a little while when the adapter is out so I know it holds at least some what of a charge. After removing the power adapter for about 20 min it dies. The adapter itself is a bit loose on the male side so that I have to wiggle it in order for the charging icon to show up in the status bar. I'm trying to determine if there is a better way for me to figure out whether I have a battery issue or a power adapter issue or both. Any ideas?
Also does anyone know where the best source to buy a replacement adapter is? Seems like the after market ones on Amazon are all poor quality based on the reviews.
