hi sootnsmoke
I'll tell you my experience, a laptop manufacture (Not HP) created a Battery Management software to manage their laptop batteries, the software charges the battery only upto 80% and keeps the remaining 20% un used, they thought this might give the battery long life, but you know what happened that 20% got spoiled because it never used so they informed us to remove that software also now they have removed that software from their new products.. I think thats the reason
