I replaced my ASUS laptop battery because the charge light started blinking orange and the battery would only last a couple of minutes before dying. This condition started suddenly, not with the usual slow decay in life. A new battery solved the problem, but after a few weeks the same thing happened again. I've now replaced the battery three times and still have the same problem. Obviously, either the computer charging circuit has a problem or the batteries are failure prone. So far, I have used generic batteries (not from ASUS).
My question is whether it's worth buying an original battery to see if I have better results, or whether this is most likely a motherboard problem. While I realize that 3rd party batteries may not be as good as the brand name ones, it seems a bit unlikely to me that three would fail in the same way, so I'm hesitant to invest in a relatively expensive "original" battery if my computer is just going to destroy it.
