I own a Compaq M2015LA Presario Laptop, The battery it´s been dead for 1 year. I continue to use it only with AC adapter. The adapter finally went out. So I decide to order a new Battery and AC adapter as well. It powers up but does not charge the battery. Battery was good and new. I used the fully factory charged battery until dead, before I try to charge it for the first time. Any ideas????
