My GameBoy Advance SP came with a little booklet saying that the internal rechargable battery it has inside (which cannot be replaced by the user) has so many charge cycles in it. I can't say more specifically what the effect is to do this middle ground option, but as long as your battery gets a recharging a few times a month that will be enough to keep it holding power. You can go ahead and unplug that AC Adapter, move it and then plug it back in if you wish to do so, and during that time, your computer kept on doing it's thing (can your desktop do that?) with maybe the only effect being that (depending on your system settings), your screen's display might have dimmed for a couple minutes - if you have it set to dim to a lower brightness amount for battery power compared to AC Adapter power.Īlso, I have heard (like many others have) that if you never actually use your battery, that it will die quickly from notĮnough use, but if you are constantly recharging your battery, you can expect it to slowly lose what used to be it's full capacity (in the long run, should last 2-3 years anyways I would guess) but one would assume that only recharging your battery once a week or so and using AC power with it for the most part would extend the life of you battery (and if you don't like to use it alot, then it makes sense to not want to have to purchase a replacement battery after 2 years or so, just so you can have one available if/when needed). You can move it around with it's small form factor and lighter weight, you can use it anywhere with the battery and having bluetooth and WiFi to use for Internet/accessories/PDA and Cellphone connections, and the battery can act like a built-in backup power supply unit (PSU) which is not just good for storms and other power outtages, but even if you just want to move the location of where you have your laptop (from one room to another) while it is turned on and doing stuff. ![]() That's one of the benefits of using a laptop as a desktop replacement actually. I do this once a week or so, just to keep the battery's power moving out and new power in, and I might re-calibrate (spelling?) the battery once every couple months to help keep the battery "knowing what it's full capacity is" and therefore keeping the battery life up to a more full capacity and for a longer lifespan. Then when it gets down to a low percent of power (10-20 % maybe), then I will plug the AC back in and let it charge up again. I will periodically un-attach the AC Adapter and use the laptop with the battery alone, or even just let it stay in sleep mode while I am not using it and let the battery slowly drain away. This is what I do with both my MacBook and Dell XPS m140. To add to what Kappy said, it will not harm your laptop to leave the AC Adapter plugged in at all times, and it will be a good backup (in case of power failure etc) to have your battery in place as well. Likewise, when you mark a reply as Helpful or Solved in your own created topic, you will be awarding the respondent with the same point values. Members may reward you with 5 points if they deem that your reply is helpful and 10 points if you post a solution to their issue. When a community member gives you (or another member) a reward for providing helpful advice or a solution to their question, your accumulated points will increase your status level within the community. The reward system helps to increase community participation. Why reward points?(Quoted from Discussions Terms of Use.) Partially discharging and then recharging the battery will not shorten its life. The MacBook battery has an average life of 500 full discharge/recharge cycles. Lithium-Polymer batteries do not lose charge capacity as do the older technology batteries used in your Powerbook. A fully charged battery cannot overcharge. The charging circuitry shuts off charging once the battery is re-charged until the charge level declines below 95 percent. If that's not a problem then you can leave the battery out. You can run the MacBook without the battery but if you do the CPU will automatically throttle down to a slower speed.
