I've been considering of getting as my next laptop a macbook air. Now they have flash storage and what I was wondering is the following: Is there a possibility that if the battery is completely used and there is no power, you will loose the information on your computer
View 4 Replieswhy is it when i shut down my mac i loose information like bookmarks,desktop files and my I photos?

MacBook, Mac OS X (10.4.11)
I just ordered my first mac a few days ago online, and seeing that almost everyone takes advantage of the suposed 10h battery of the 13', I wonder if it gets slower when you are using the battery.
my current notebook (compal FL90) is considerably (much) slower when it is not powered to the grid especially if I'm running photoshop for casual editing.
It's sort of come to my attention there's a few of us who are having *experiences* with a loose cover/latch. I wouldn't call this an *issue* at all, (yet) or it could be a problem with us being too picky. Either way, I'd like to know.

Is it possible for a sharp and sudden fall to disconnect the battery in the Macbook Air? My friend just emailed me--her husband dropped the MBA from the kitchen table to the floor (so just under 3'). She has an X icon where the battery icon should be and for the first few restarts, she's had to reenter wireless password information, as well as date/time. The MBA works fine when it's plugged in. But there's "a teeny dent in the upper left corner. Really tiny."

View 24 Replies View RelatedWith mine, when I drain it completely, it just shuts down, i.e. it doesnt go to sleep mode as there is no pulsating light on the front right corner. Once I start charging, however, and I can again switch it on, it resumes where I left off, so the computer has saved the contents of the memory onto the hard disk. On my SR MBP it was different, it would actually go to sleep mode when the batteries were almost completely drained.

So when I charge my macbook pro retina display too a 100% and then when I come back the next day and turn it on the battery has drained by itself by like 7%. Sometimes they are even drastic changes like 15-20%? I have just bought this macbook and is only a week and a half old? What should I do?

I have read about Macbook Pro batteries from apple.com. I use to talk to many people and ask about batteries which brought me upto this confusion. Well, my question is, should i charge macbook pro when it's battery is completely drained or it's okay to charge at any time as long as it's not at 100%? For example, I wanna start charging it while its 60% and make it to 100% or Don't charge it until battery reaches to 5 or 10 percent.

I got my first Mac last Sunday (woo!) but I was using it last night and a battery warning came up. I had been using the MBP, then turned it off and went out with battery still remaining. When I came back again a few hours later I used the Mac and after about 10 mins closed the lid for some reason. When I opened it back up it wouldn't start unless I plugged in the power outlet - the thing had completely drained. Then I checked the battery and it says to 'Service Battery'. It's now holding a charge as normal as far as I can see but the warning is still there.
A couple of other things I notice too:
- When I tilt the MBP to the right sometimes a scraping noise comes from the inside - maybe from a fan?
- When I pick it up from the bottom, the bottom of the Mac dips inwards slightly and there is a click as it makes contact with something on the inside of the case.
Are these things normal? I've made a Genius Bar reservation but I think I might just swap it for a new one.
When I close the lid on my MacBook Pro (Late 2008), the battery drains almost completely over a night or so! Very odd. Anyone else dealing with this? I reset the PRAM already.
View 24 Replies View RelatedJust wondering if anyone has ever encountered this or if any experts out there know of the issue.I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.
I just turned on my 13" MBP and got this message. Apparently, this is supposed to come up when there is only like 5% charge left. My battery indicator at the top of the screen said there was 22% charge left. Also, according to IStat, my battery's health has already dropped down to 97% after only about 2 weeks and 5 cycles. Is this normal? I'm going to try recallibrating my battery by fully charging it and then letting it fully drain. Is there a good chance that this solves this problem?

And I would like to know how to completely powerclean my computer, I know that most of the things you delete or visit somewhere on the internet, or messenger conversations still get stored somewhere inside your computer, but not possible to find or simply delete. I want my computer to be faster etc. again because sometimes it's getting a little slower than it used to be. Also I maybe want to sell it, so I thought this would be useful then. I don't want to reinstall mac OS X again, because i have many important files, photos, memories, ... etc. on my computer and I am too lazy to make a huge backup. Any good free downloadable software that deletes all the hidden files, messenger history, caches, deleted files, etc.
We own a powermac G5 that has had some problems in the past, but nothing like this. When we press the power button there is a chime and fan that shows everything is working up. A white screen appears with the apple sign showing that it is loading. After this screen has been loading for a while the computer just shuts down completely.

Pressing the power button on the main unit, the button lights, then flashes, long-short, long-short, etc.Nothing else happens - no screen, no chime, no disk activity. can I get this (and other) Power-on Self Test (POST) information?
View 3 Replies View RelatedAs I just bought a 13" MBA, I am still in my "babying" phase of the machine and want its battery power/capacity to last as long as possible. I have already done the battery calibration recommended by Apple (not even sure if its 'necessary' but I did it anyways), with charging, resting, draining, resting, and re-charging. But now I am worried about the battery cycles. Should I only plug my MBA in when the battery is close to being drained (aka use it on battery power for most of my usage?) or is it okay to drain the battery to like 80% remaining, charge, and then drain to 70% remaining, then charge again? Im not sure if Im making sense, but basically I don't want to be wasting these valuable cycles, as they seem to determine battery health and longevity. So what is the proper battery usage for the MBA, or is it basically use off power when you want and use on power supply when its available?

I recently discovered my computer had died while it was sleeping. I tried charging it but am recieving the "Battery not charging, power source: power adapter" status.My power cord light is green, always. and the computer dies instantly when I remove the magsafe.
I've tried the "remove the battery, press the power button, plug in the magsafe" troubleshooting process, but it doesn't work.I've noticed that even with the battery out, the charger reads a green light.I've tried several outlets with the same results.Here are my battery statsÂ

My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

I have a mid-2007 MBP. Here is my issue...it's been more than a year that when I totally discharge my battery (meaning the MBP shuts down), when I connect it back to the charge it is taking abotu 10 minutes to power up again...it was not the case before and my wife's MB is working well....meaning when it is down, just connecting the charger the MB is back on within a sec.
I have changed my battery but it did not change anything, I called Apple and they recommended me to restore snow leopard...which I did...I still have the same issue.
Does anyone experience this? Any idea what is happening (HW or SW issue) and is there a potential fix?
I have just bought a second hand MacBook laptop and it has a wierd battery issue that can't seem to find mentioned anywhere.Initally all seemed fine, but then I noticed the battery wasn't charging and the battery menu reported no battery found, also the MagSafe plug had not light; some searching instructed me to reset the SMC which I did, and everything was fixed, I could runs the computer from the battery and the power lead charged the battery. But now (just a day later) the battery won't power the computer at all - the computer will only work if the power is connected - however the light is shown on the MagSafe plug and the battery is being changed, but if I disconnected the power lead, first I see the restar/sleep/shut down dialog that you see when pressing the power button, then shortly after the computer turns off, if the power if reconnected, it boots from scratch, so it wasn't asleep!

View 1 Replies View RelatedThe 2011 macbook pro with i7 processor will not power up or charge at all. The problem started after my battery ran out and the computer shut down. Since then, when I plug in the charger only the green light turns on. In addition the light on the base (in front of the keyboard) flashes. Nothing happens when I hit the power button. The charger still works on other laptops. To emphasize, the screen will not even light up. It sounds as if the computer is starting (for less than a second) before stopping, only to start again but that is purely speculative.
