Just bought this MSI CX62 6QD-047US from Amazon Warehouse. Everything was going great until I realized that the battery wasn't charging. My laptop only works when I have it on the charger, as soon as I unplug it it dies. It has a non removable battery in it. I tried using the battery reset button, but that didnt work either. Drivers are up to date as well. Any ideas? I would really like not to have to return it.
