Apple :: MacBook - Using On Battery Power - Closed The Lid -won't Start Up Again
Dec 13, 2009
I have a MacBook pro which I was using this morning on battery power, closed the lid to take a break, now it won't start up again. Tried plugging in the mains but nothing?
The small 'sleep' light at the front isn't pulsating as normal but is on all the time.
A few weeks ago my battery started to function poorly...checked out the diagnostics, showed it was in "poor" condition. I planned on going to Apple store soon but now my power adapter has also seemed to have gone bad. I plug it in, but no power goes to the Macbook Pro ( I can start it on limited battery and see no power being received) and the little green light isn't going on the plug into the computer itself. The power brick or whatever you want to call it gets very warm but I think that could be a malfunction? Before I call Apple do you think I just need a new battery and AC adapter?
I'm having some issues with my MacBook's USB hub. I have the macbook from 2007 I believe that has 2.0GHz and 1GB of RAM. WHenever I connect my iPhone to the USB port to sync, it pops up with this dialog box that says that my iPhone is drawing too much power and thus the USB hub will be deactivated.
yesterday my SSD took a dump and replaced it with my stock HDD (160GB). My boot time with the SSD was 21 seconds. I did not install EFI 1.7. Now, with the 160GB, the boot time is 1:10. Is that normal? What can I do to make it faster?
I am looking into getting one of the new macbook pro's. Though I must say the non removable battery does concern me a bit. In past laptops I have had, I without a doubt saw increased battery wear and tear when I left the batter in the laptop while the laptop itself was plugged in. I completly destroyed a battery on my Dell laptop by doing this for about a month when it was asking as a desktop. I took the laptop which used to get around 4 hrs of battery life and then after a month it got no more than 15 minutes.
So after that I always took the battery out, so now with the new macbook pro's you cannot take the batteries out, so wont the batteries wear down to nothing faster than if you took them out when not using them?
I will be teaching in China with my MacBook with OS X. What do I need to enable me to use Chinese electricity? Do I need to know anything special to hook up to the internet at a university or an internet cafe? I will be in & near Beijing.
I am looking for a reliable car power inverter for my 2007 Macbook Pro. My car has 2 power outlets (12V / 120W). I know there is a 15A fuse, so the maximum it can handle is 180W, but of course I do not want to take that risk and stay around the recommended 120W. Because of this, it limits the number of choices I have concerning power inverters. I have seen one from Duracell called the Pocket Inverter 100. Here are the specifications:
AC Output Power (Max Continuous): 80W AC Output Power (Peak): 100W AC Output Surge Capacity (Peak): 160W AC Output Voltage (Nominal): 120V AC Output Waveform: Modified Sine Wave
So, this leads to a few questions:
(1) The MBP Magsafe Adapter requires 85W. However, this inverter can provide only 80W of maximum continuous power. Will this be sufficient to charge and run the MBP in the car?
(2) I searched around and read a few posts by others regarding pure sine wave and how it is important to have it running to laptops. Now, this inverter has an output of a Modified Sine Wave. Will this be fine and will the Magsafe adapter be able to handle this?
(3) recommendations for car power inverters within these specifications?
My 3 months old unibody macbook pro power down itself when i am use batteries. i did smell somethings burning after it is been powerdown, do you all face this by the way i am just surfing cnet tv, call apple singapore and they ask me to bring to HQ
I have a Latitude E6510 that will not start. When pressing the power button, the power light goes on for about 5 seconds and then turns off. I also notice the battery light flashes a few times when re-connecting the AC adapter.
Removed the battery, held in the power button 30 seconds, but still not working.
We have had this laptop about 6 months. About a month ago, it exhibited this problem. After talking to Dell Support, they recommended a system board replacement. The laptop was sent in and the board was replaced. When I got it back and tried to start it for the first time, it did the same thing. I then pressed the Latitude "ON" button, and the laptop started.
Now it is doing the same thing, and I find it hard to believe that another system board is bad. I am suspicious about this "ON" feature, that maybe the laptop is "stuck" or something trying to get into the "ON" mode. Or maybe it is just trying to get into "ON" mode.Â
I am not sure what the "ON" feature does, but I have noticed a few other posts on the internet of users having the exact same problem. Again--I find it hard to believe a second system board could be bad.
I just want to get an idea of the power of the 9600m GT video card that comes with the macbook pro's. Now on my desktop computer I have a 3 year old ATI 1600x 512mb PCI-e video card which is definitely getting old. My question is can anybody tell me how the 9600m GT compares to the ATI 1600x, is it better? this way I can get an idea of the power of the 9600m GT because I know pretty well what the 1600x is capable of.
I need to replace a battery in my First Generation MacBook Pro. Is new battery released for latest MacBooks Pro is going to be compatible with it? Or I have to look for a First Gen battery (A1189)?
I'm not even coming close to this with my 2010 macbook pro 13 inch unless I turn my brightness down to 50%, on reboot it defaults to 100%. This is when doing nothing or just surfing the net. I can get about 7 hrs, with my laptop screen turned to 50%. Any tweaks available? I'd love to know how Apple came up with 10 hrs.
is it true? so what if i dont really bring my macbook pro 17 around with me? normally just gonna put it in my house, if i 24/7 keep on using the adapter would the battery easily die?
I use my macbook a lot lately without connecting it to a power outlet. I disconnect it from power supple in the morning and put it in my backpack, and after 3 hours I waked it up by opening the lid and I notice the battery is at 95%. The battery is pretty much out of power after about 4 hours of use with airport on for wireless connection, and at the lowest brightness. Is it possible there is a battery leak, or is this normal? The battery is at 99% health and 40 cycles. It was went down to 96% health before, and it came back to 99% after I calibrated the battery.
I have a Macbook Pro I bought in summer 2007, and I'm have concerns about its battery life, and so I was wondering if anyone could help me please.
I hardly ever use my laptop away from my desk, so it's plugged in all the time. While plugged in, I still keep the battery in the laptop. It's only been through 10 cycles in 2 years, and I know I should've calibrated it monthly, but I didn't and I really wish I had now. Right now, when unplugged, my battery only lasts about half an hour. I downloaded coconutBattery and apparently, my original battery capacity was 5600 mAh, and now it's only 543 mAh.
My question is, did I mess up the battery myself by not calibrating it, or was the battery defective in the first place? :S Or is it just old?
I'm a real n00b when it comes to computers....but if this ISN'T my fault, the laptop is under an Apple Care Protection Plan, and so would that cover the battery? Is there any way to fix it without getting a new battery?
I bought a new white macbook a few days ago. I just noticed now the batter meter says "not charging" and its only at 95%. Is there something wrong with my battery? should I drain it all the way and then recharge?
i've just purchased a 2.0GHZ aluminum macbook recently and am having a small problem with it. The macbooks battery percentage indicator seems to be dropping a percentage point every couple of days even though i'm on mains power? The power adaptor LED is green idicating the computer is fully charged. I've calibrated the battery as apple recommended but its still doing it. The apple tech guy said that it is possibly a 'power board' problem rather than a battery fault and it will need changing. Has anybody else experienced this problem? Other than this small problem the macbook is fantastic, should have coverted over from a pc years ago
how long the macbook pro battery last. The 17" is 8 hours and 15 and 13 " is 7 hours. I would just want to know those who own a macbookpro. How is you macbook pro last according what it advertise?
I normally just want office work,web surfing, chatting, editing pic and youtubing and little game.
Looks like our hunches about what's inside the next MacBook Pros are panning out: AppleInsider hears that Apple's got new MacBook Pros running that can switch between integrated and discrete graphics automagically, which exactly describes Nvidia's Optimus dual graphics tech.
If you remember, the unibody MacBooks from Oct. 2008 were the first to use Nvidia's GeForce 9400M, a combination chipset/integrated GPU that ridiculously outperformed Intel's own integrated graphics, and the Pro models at the time could switch between power-saving integrated and beefier discrete graphics, though it requires a logout.
Nvidia got cockblocked from making chipsets for Intel's latest-gen chips (read: Core i3, Core i5, Core i7), ruling out using Nvidia's better integrated graphics; Nvidia canned their chipset business entirely. So! Nvidia's Optimus tech works with Intel's crappier integrated graphics that are built onto the same die as the newer Core processors, but even more seamlessly than before—the computer automatically switches between Intel's power-sipping integrated and Nvidia's monster discrete graphics, depending on what you're doing. No logouts required.
In the demo we saw on a Windows machine, the automatic part of the tech has some drawbacks—namely, it's entirely dependent on software to tell your computer which graphics card to run. But Apple's obviously worked pretty closely with Nvidia on graphics before, so it seems logical they're doing so here, too. Though I don't expect we'll know until the new MacBooks finally arrive, whenever that happens (hopefully, soon).
As a new 13" Macbook Pro owner, I am wondering if upgrading with non-Apple certified HDD and RAM components could drastically effect the battery life.
I am told that there is firmware in the HDD of the one that comes with a Macbook that is necessary for maximum battery life. From comparing two HDD's in my Macbook (one certified and one not) I think this might be the case. What is your experience?
Also, does there exist Apple certified RAM and, if so, does it offer more battery life compared to non-certified?
I have just bought my Unibody Macbook. I haven't received it yet, but I was wondering if anyone has any tips on undervolting, buying a different battery, etc. to get more battery life on it. I really need it for school and I don't always like sitting next to the plug in a classroom.
I had a MacBook unibody for about a week while I installed Bootcamp XP/etc on it for my daughter - then I shipped it to her. I would like to get one for myself later this year, funds permitting. However, I have seen comments in several posts about potential problems with the battery cover. Does the battery cover have a design weakness or is it just really tricky to re-attach to the system?
