Strange thing just happend to me. I decided to leave my laptop on without charging and it lasted for awhile and died. Come this morning, I plug the charger in and it seems to work! 🙂 I'm not sure if it was a glitch, but I was prepared to replace the battery. Maybe a moderator/ someone who knows a few things about these laptops could share more info on the subject. In addition, I ended up buying another charger thinking mine was dead, I used it to power on my laptop before I had identified that the orange blinking light was not going away.
