My laptop battery died and would not hold a charge. I just bought a new one and my sister told me my old one died because you’re not supposed leave the battery in and get on the computer while it’s plugged into the wall.

I’ve been doing it for about a year before my old one died and I don’t think it makes that much sense. I don’t want to mess my new one up so if you know anything about this please reply.

My Laptop battery is at full charge, but when I am using it in my bedroom I just keep it plugged in so it won’t use any of my battery life. Do you think it’s bad for the battery to keep the laptop plugged in after the battery is fully charged? I have left my laptop plugged in for days already without using the battery, but I don’t want to kill the battery by doing so. You know what I mean?

Thanks much!

It’s a Toshiba Satellite laptop, made this year, Windows vista, yadda yadda. Look my point is, if my battery gets wasted to a point where it won’t charge anymore, will my computer still work plugged into the wall? I can’t afford to get another battery. I can’t afford a pack of cigarettes.

I thought you were supposed to charge them fully, then let them drain almost completely, then charge them, and so on.

But this month’s issue of PC World says that’s only the case for (older) nickel-cadmium batteries, and that current lithium-ion batteries have “the opposite problem”—does that mean they best keep their capacity if you leave them plugged in as much of the time as possible?

Ive got an old Mac Powerbook G4, and ive noticed lately that the battery continues to drain even when its plugged in while im using it. When i stop using it the battery charges back up. Can you have to many accessories plugged into a laptop so that the battery on it will drain even when the computer is plugged in?

I currently have 5 external hard drives connected (3 of which drawing from their own power cords) my iphone and my ipod.

I know lithium-ion batteries run for a certain amount of charge-discharge cycles, but I don’t know if any cycles occur while the battery is fully charged and plugged in.
