Hi all,i am using windows vista,and recently my dell laptop battery would not charge at all,so i purchased a new battery (non dell) and initially would charge but was intermittent when i plugged power cable in when it would decide to charge.

The charger is fine,as its keeping the laptop going and symbol states its also plugged in.

Now i cannot get the new battery to charge, even after letting the power die on the battery,3rd time since purchased,after initial full charge the first time??
Can this be overcome by some settings,or do you think it maybe a hardware issue
