Plugged In, Not Charging problem

My Toshiba Satellite laptop running Windows Vista seems to be having problems charging.  Just recently it says "Plugged In, Not Charging" when the power cord is plugged in.  I found that if I unplug the power cord and plug back in, it starts charging for some period of time (5-10% increase) and then quits again.  

I thought I was taking good care of my battery, I would always let it charge to 100% and unplug the power cord and then let it almost completely die and then repeat the process.  Is this bad?

I would check your power cable pack thing. Are you able to borrow one from somebody else to see if that's the issue?

It's a good idea to let it die completely once in a while, but not every time it's fully charged. The battery in a laptop is only good for x number of full charging cycles. The charging function in modern laptops is sophisticated enough to prevent overcharging when the plug is left in.

It depends on the battery type. If the battery is a lithium type you don't need to let it drain. The older battery types such as NiCad and NiMh need to be drained completely to keep them in peek shape, modern batteries don't require that.

I am unable to borrow someone else's battery charger.  Any other ideas?

>>I found that if I unplug the power cord and plug back in, it starts charging for some period of time<<

This idea works on the theory that the battery is so dead that the charging routine doesn't recognize the battery properly.

You could try repeating the process of plugging it in only for as long as it's charging then unplug and re-plug to start it charging again. After several times it will build up enough power in the battery that the laptop will recognize that there is a dead battery present and start charging fully.

OK, I am doing this right now, I am up to 44% by unplugging and plugging back in all the time but it is still only charging for 5-10% at a time.

Well, there goes that theory! If it's at 44%, that has to be enough for the laptop to recognize the battery properly.

unplug the power cable , remove the battery for 5 mins then plug the buttery and the power cable.

I had the same problem in the past with my HP laptop, and that works with me!

if that did not help, i afraid that the buttery is faulty.

It worked!  I left the battery pack out over night and when I plugged it in it charged to 100%.  Thanks.
