Years ago, I had to return/replace this type of a battery several times because of erratic behavior in the laptop. Suddenly I had one that lasted for 5 years before not taking any charge anymore. So, I'm going to order a new one hopefully without having to restart the return charade BECAUSE:
I observed that the battery's CONTACTs are unreliably INTERMITTENT. So far, it helped for a while moving it in and out in order to chafe the contacts' surfaces against each other.
