Can I use my MacBook without the battery inserted?

If the MacBook is anything like all of Apple's previous laptop then yes… you can use it without a battery. Although, with the magsafe adapter I would highly recommend keeping the battery inserted. These adapters do come off very easily and you may find your laptop going off without warning.

Additionally, I do strongly suggest you constantly use your battery. It will extend it's life rather than shorten it. Not using the battery will actually shorten its life.

Finally!
If I use the battery even when I've the power cord
connected they not will be damaged?
If i disconnect it ,the clock goes down at 1 giga and
thre's no protection from electric shock...
Wich is the finally word?
It is best to use or not to use the battery when use
electric power ??

From the article http://www.apple.com/batteries/notebooks.html, you should use your battery as much as possible.

I've had my MacBook for just one week and, like the first poster on this thread, use it as a desktop at home, not as a portable.

Because the battery in the VAIO I used as a desktop for six years made the clock lose a few minutes a week, I removed it and inserted the space saver. That was the first thing I intended to do after taking this MacBook out of the box but, unlike VAIO, MacBook has no such thing: the battery compartment cover seems to be an inseparable part of the battery itself.

I'd really like to remove it and leave it packed away in the box for the next however many years I use this thing. I considered improvising a dust/insect shield (paper or plastic and tape?) to protect the void which would remain on the underside of the MacBook, but I suspect that would horrify any conscientious technician.

The question remains: is there a safe way to remove the battery and protect the space from intrusion (dust, insects, objects, whatever)?

Keep your desk area clean, the insect will unlikely to be around a clean area.

But battery technology is better now and it doesn't have memory effect anymore, and longer life altought it still have a certain life span period not eternal life.

If you are affraid the battery fail and mess up with your clock, set it to adjust automatically at the system preference > date & time and check the set date and time automatically option.

Remember, choose a correct timezone first, otherwise it will keep displaying different time from different zone.

Back on lombard and pismo G3 laptop era, apple sells hollow battery casing as a weight saver, I don't know if apple had a plan to sells another one like that for MacBook. Could be, could be not, it is apple decison or third party decision to make.

Yes you can but the processor will default to 1ghz
mode.

Imola, I found this strange decrease in performance too. Could you please explain why Apple implemented this feature (or bug?) to our MacBook?

"Not a bug, but a feature..."

The battery cushions CPU requirement spikes which results in requested current increases. The battery takes the edge off the power supply.

When there is no battery available, then the power manager notifies the CPU, and the CPU orders a throttle back on itself.

It is a good thing... efficient design.

I'm sure if someone was really smart, and there was a real demand in the market for battery-less operation, a space-saver could be designed using a capacitor, similar to what car stereo enthusiasts do for smoothing voltage requirements when the "thump" is cranked up for the audio amplifiers. I'm just guessing. But, by that time, such a space-saver would probably end up weighing more than the battery it is replacing.

I would describe a charger that is under-rated to supply power top the laptop as neither bug nor feature but bad design!

On this basis, what happens when the battery is flat at 0%, does it go down to 1Ghz?

If it drops to 1Ghz CPU speed with no battery, why is it stuck at 2Ghz on battery and making my MacBook a portable space heater as well as a laptop?!

"Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge. This keeps the battery juices flowing."

from the apple page, i understand it by that fully charged batteries should not be plugged into the adapter for a prolonged period of time, but to be expended a while before plugging in the AC again. do you all understand it in the same fashion too?

seems like a rather troublesome affair, but i'm imagining holding my macbook around the house (and toilet), and i think it's nice =p

Yes you can but the processor will default to 1ghz mode.

Can I contact you in private (In italian) ???
Thanks

With my current notebook, when it's unplugged, it slows down and the screen dims. It's not apple. You're saying to do that with the MacBook? That's cool. I hate having a cord.
