Is it okay to just have the AC adapter plugged in w/o the battery in?

Since this is my first notebook how do I prolong the battery life of the 9 cell battery? Recently I have not moved my computer from my desk. Right now I have the battery in with the AC adapter plugged in as well.

Sometimes I remove the AC Plug and just run off the battery and when it hits 8% I recharge it.

Also sometimes I remove the battery and just use run of AC power.

For the people that hardly carry their notebooks with them, what do you guys do to maximize battery life?

 

First off, *don't* fully discharge the battery if you care for its long-term service life. Lithium-ion batteries prefer shallow discharges and frequent recharging. They have no memory effect like other competing battery chemistries.

That said, your laptop will operate perfectly fine on AC power only with the battery removed.

For best results when preparing to store the battery out of the laptop, bring the battery charge level to 40% capacity (i.e. 60% discharged) before removal then store the battery in a cool, dry place.

It is actually a good thing to take out the battery and run it on AC. That way you don't wear down the battery

 

also, if you take it out and if the power cuts off then you loose information, create fragments on the HDD, and cause eventual problems to the OS. I prefere to work with laptops rather than on desktops just for that reason.

that's like saying: if you buy a new car, and if you never use it, then it will remain new for long time ...

but to your original question - yes, you can take the battery off

 

I think you're over thinking things. The Power Manager can be set to not charge the battery if it is over a threshold, typically 95% of full capacity. The battery is going to lose capacity over time anyway, even if it is stored outside of the PC. You're better off just using the machine normally, plugging it in when possible, and definitely do not deep cycle the battery unless you need to. One thing to keep in mind -- if you remove your battery and just run on AC, your laptop will shut down when/if you lose power. Any savings that you might gain in removing the battery may be instantly negated by work lost in a power failure.
