Am i supposed to keep the charger in my macbook air

I started charging it when it was at 30%. its now at 100% and I've kept the charger in. Is this good for the battery life or should i remove it once it is at 100%...? and is it okay to begin charging around 20-30%??

its perfectly fine to keep it plugged in when it reaches 100%, and yes, recharging between 20-30% is also ok. Read this for more information: https://www.apple.com/batteries/notebooks.html

HP Battery, Is It OK to keep the charger plugged in ?

Hi All
This is my first question here and I hope you'll help me
I want to ask if it is OK to keep the charger plugged in the laptop while the battery is full ?
I mean when the battery is 100%, will the energy go directly to the PC or it will go to the battery before ?
This question was solved.

Hi,
Nowadays batteries should be smart enough to stop getting charged when full. I can't see the difference from removing and keeping batteries on AC, some machines sit on docking stations all the times and some machines can be ON/OFF. This is my reply to another post:

No Internet during power outage - Isn't the battery in the NTU supposed to keep the circuit up?

During yesterday's power outage in Northern Virginia I lost all Internet connectivity; yet my NTU battery was up but my Verizon router was saying the cable wan was down. Why?
Isn't the NTU battery supposed to keep the circuit up in case of power failure? if is not, why did I spend $30 replacing it when it failed since Verizon is too cheap to replace it, even though we all pay them those outragous bills every month.

No, only the phone circuit, for up to 8 hours, if you have phone service. Although my experience is that the battery does power the internet and TV service for a short time to cover a brief power outage.
As to why you paid $30 to replace the battery, I have no idea, you can generally get batteries locally or from Amazon, etc. for $15 to $20. And it is very clearly stated that the battery is your responsibility, you should have already known that.

Can I use my iPad mini to extend the display from my Macbook Air?

Is there a way to utilize my ipad mini wifi, to extend the display from my Macbook Air?

There is no need to charge it before you first use it. You cannot run the battery too low as the system will shut the device off before that happens to protect the battery.
Generally speaking, your Lithium battery will have the longest useable life if you avoid deep cycles. Since you can plug and unplug it as you wish, the best thing to do is just charge it up (however much) whenever it is convenient to do so (whether it is 10% discharged, or 20% or 50% - basically don't pay any attention to the battery level, just plug it in when it is convenient to do so to keep the battery topped up). And try to avoid frequent deep cycles where you run it all the way or very near to the point it auto-shuts off.

TS2570 trying to reinstall the OS on a MacBook Air.

I'm trying to reinstall the OS on a MacBook Air. I got it from my former company, and they didn't keep the OS install disc, in fact they wiped it and put Windows 7 on it. I have quite a few macs, and have always used an external USB disc and can install but this machine is so fickle and throws up the multilingual failure message upon boot. I was, however, able to boot into a recovery volume that was on my external hard drive, and I burned Snow Leopard to the machine's OWN hard drive, and when it booted up, it failed again.

Welcome to the Apple Support Communities
You have a Mid 2012 MacBook Air. This MacBook Air isn't compatible with Snow Leopard, and that's the reason why you are getting a kernel panic when you try to start up Snow Leopard.
In order to reinstall OS X, you can use that recovery volume or Internet Recovery (hold Command, Option and R keys while your computer is starting). Then, open Disk Utility, choose your hard disk at the top of the sidebar, go to Erase tab and erase the drive. Finally, close Disk Utility and reinstall OS X

Should I calibrate the battery in my MacBook Air?

My pc crashed. All my info is on excel in my pc. I managed to print out excel. Can I transfer the printout to my MacBook Air excel?

I have a pc that has the majority of my info. Two years ago I purchased a MacBook Air. Recently my pc crashed and I am able to start it up for very short periods of time. One of those moments I printed out a worksheet in excel. My question is am I able to scan the printouts and get the info into my MacBook Air excel, or by any other means. I was unable to save the excel worksheet from my pc into my memory stick, but I can try again, if necessary. Thanks

If you can fire it up long enought to print, surely you can copy the documents to a flash drive in less time. Keep trying.
Scanning spreadsheets and using OCR is going to be tough, nevermind getting any formulas.
If the Hard Drive is not the cause of your maladies, then I would use a USB drive adapter to copy the files to your MBA. The cost of an adapter is around $25-$30. I'd say it beats the heck out of trying to make use of printouts. I use an Apricorn Drive adapter. Since you don't menti0on the cause of the system crash, I can only guess and probability says its the drive though, for which this won't work.

I lost the connection between my MacBook Air and Bluetooth wireless speakers (Logitech) when updating to OS 10.7.4. Tried all the "fixes" I could find, no results! Can you help?

Error message as above and below:

BT won't deal with this - they redirect me to a 'partner' who want to charge to discuss the problem. Nice, eh!

The fan sound of macbook air

Is it normal to hear the fan sound of macbook air. not all the time

Welcome to the Apple Support Communities
Sometimes, when you are doing heavy tasks with your computer, temperature increases. Your Mac turns on fans automatically when temperature increases a lot, so it will keep your computer safe. It's normal and you shouldn't be worried if this doesn't happen all the time

I would like to know how do I install the brazilian keyboard into macbook air, keyboard with accents (Portuguese Language), I tried so many times how to put into it (Macbook Air). So, thanks for now! I'm waiting for it.

I would like to know how do I install the brazilian keyboard into macbook air, keyboard with accents (Portuguese Language), I tried so many times how to put into it (Macbook Air). So, thanks for now! I'm waiting for it.

After you go to system preferences/keyboard/input sources as suggested by sberman, click on the + button and scroll down to Portuguese and select that. Over at the right you will see the choices Brazilian, Brazilian abnt, Portuguese. You might want to add all three to see which you like best.
The "Brazilian" layout is pretty useless. It is identical to the US layout and the only way to make accents is via the option key shortcuts: option + n, then o gives you õ.
The Brazilian abnt and Portuguese layouts have dead keys for adding accents over at the right edge of the keyboard. But these may not match what is printed on your keys.
You may prefer to stay with the US layout. On that you can get accented letters by just holding down the base letter and selecting what you want from the popup menu that appears. Or you can use the option key shortcuts.
Another option is the layout called US International PC, which has accent deadkeys on ~, ', etc.
Which ever layout you want to use, you must select it in the "flag" menu at the top right of the screen.
To see which key does what for any layout, use the Keyboard Viewer:
