I bought a laptop from Dell about a week ago and I plan to use it extensively. I`m talking about around 4 to 8 hours of use in one sitting. I know using a PC would be the smarter choice, but this just out of my curiosity. I`ve been taking the battery out to save it from over heating when leaving it on for a long duration. I`m also trying to make the battery last as long as possible, when I do decide to use it on the go.

And one more thing... The battery is on the bottom of the laptop (of course), but there are these supports that lift it up from the back, so the laptop slants towards you a bit. I think this makes it easier on some people, but I believe the real reason for the supports is to lift the vent from suffocating on the table. Two vents are on the bottom, two vents on the side. All are used.

So my question is, should I leave the battery in when using it for long hours, or should I take it out and just plug the laptop into the wall? If I do take it out, does it affect anything?

Thanks.

I guess I could, but I'm not really willing to put anymore money into this.

Here are some things to know about the type of battery that's powering your Dell laptop.

-It's a Lithium-ion (Li-ion), these are the most common used today in almost every consumer electronic devices.

- These guys don't have memory affect syndrome where a full drain is required before recharging. In fact if you do a full drain, your actually damaging it.

-These guys will degrade overtime so by leaving it out, your also ruining its life span.

-Over charging it against the specified amount of time (or %) will also screw it up.

This is why it's not wise to buy a spare battery as it just rot itself while it collect dust, by the time your going to use the spare one, it's probably long dead.

Oh, thanks for the info. So would the battery degrade faster if I left the battery out or left it in?

Basically, unless you're simply going to use the battery, you're screwed. It will ruin itself whether you leave it in the computer [with the computer plugged in], or if you leave it out.

Li-ion dyes, when it dyes. Not using it won't help as said. If you need the battery power, Opt for a bigger one. You could get a 12 cell battery. They shouldn't be that expensive.

Also, 90% of new laptops won't actually boot without the battery in. For efficiency and reduced space they power the battery from the charging circuit which directly runs onto the board's power supply. When you unplug, you're just disconnecting the outside DC source and letting the battery do the work. When you remove the battery, the external DC doesn't have a path to the board.

This is the biggest load of shit, ever. I have 3 laptops in my house, all can turn on as long as plugged in. They do not need the battery in it. But removing the battery is not going to keep it alive. Its not going to die any faster.

Just exercise it. Go on battery power, let it get down, charge it up. Not a full discharge, just use it like normal and charge it when its dying.
