Apple :: MacBook - USB Power- IPhone Is Drawing Too Much Power And Thus The USB Hub Will Be Deactivated
Aug 14, 2009
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.
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 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.
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?
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 beforeóthe 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 drawbacksónamely, 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).
Calendar and Contacts have their own icons on the Macbook but Notes is no where to be found. I did find a Notes folder in my Mail but nothing seems to Sync even though I clicked the Sync Notes Option in my Itunes.
Why can't something as simple as Notes sync between the Iphone and a Macbook?
I would like an all inclusive iphone headset that also works well for movies and games on a pc. I do not care about size, but i dont want anything to bassy or cheap sounding. I have given up on apples products, the standard iphone headset breaks way too easily on me. (THE REMOTE PART). I was also wondering where all the new headsets (the iphone one with volume control, and the high end one) are that they said would be released.
I have a Dell Latitude D800 that will not power on. When the power button is pushed the green power indicator light comes on, the CDROM spins for a moment, but then nothing happens, there is no BIOS information displayed, no power on self test, no Dell logo. It just sits there with the green power light on.I have tried removing the power & battery then pressing the power button for 10 seconds (actually, I have tried as long as 60 seconds). I have tried to turn on with the power connected but not the battery. I have tried removing the connector cable for the power button and the connector cable for the display and then reseating them.
I have just installed an i7 2670Qm on my T420 today.The machine will crash pretty soon after booting up, with the screen having colorful vertical and horizontal lines before it restarts itself and give the memory error beeping pattern (1 beep-pause-3 beeps-3 beeps-pause-1 beep).So then I took out one RAM from the bottom, and the machine appears to work normally again, more or less. ¬† In the OS (Win7 64), The power manager alerts me that the 65w AC adapter is giving not enough power, so the laptop is running on battery.¬†I thought I just need a 90W AC brick so the laptop will work as it should, so I am arranging a 90w one to come in later. But on a second thought, if the battery cannot start the laptop with 8GB of RAM properly. ¬† Is it the CPU or RAM or Mobo or something else? Where should I look?The machine works fine with the previous CPU i3-2310m and 8GB of RAM.The RAM modules I have are 2 x 4GB Samsung 2Rx8 PC3-12800S-11-11-F3.The BIOS version is updated to the latest 1.46.
I enjoy the feature of automatically powering off the optical drive in power manager. My issue is after reformatting my T530 the option is there until I do an update using the Lenovo ThinkVantage System Update. One of the updates seems to remove the feature from the power manager.
After replacing the fan, I have a power up issue with the laptop. Basically, the laptop will only power on with the power cable disconnected at the motherboard. It was by mistake that after the fan was replaced and everything was put back together, that I noticed that the battery was not charging. ¬† I then reopened the machine and reconnected the power cable to the motherboard and nothing - no power. ¬† When plugging in the power source with the battery in place, the LED adjacent to the power socket lights up WHITE then stays ORANGE and will not power up. No other lights, no fan noise, nothing. ¬† If I remove the battery, the LED adjacent to the power socket lights up WHITE and stays white however will not power up either. Same agin, no other LEDs, not fan noise, nothing. ¬† I have now opened the machine back up and disconnected the power from the motherboard. Put it all back together and the laptop powers up as normal with the battery and it works fine. (Well until the battery runs out anyway).
Our Studio 1749 will retain a solid connection when the power adapter is plugged into¬†the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.
When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?
I have an Aspire 6930 that suddenly died and will not power on.¬† The LED power button was dark and unresponsive.¬† I performed a power reset and the blue light on the power button came back on until I pressed the button to try to restart the laptop.¬† When I did that,¬†the blue LED¬†immediately went dark and stayed that way until I did another power reset.¬† It never gets to the point of anything powering on.¬† Is it a problem with the battery or it the laptop toast? ¬† This is a real bummer since I just replaced the hard drive a few weeks ago and replaced Windows Vista with Linux Mint (which btw is blazing fast compared to Vista).
Acer 5253 - Will not power on, battery or on AC power.¬† Have tried all the suggested solutions but none have worked.¬† Is it possible to get maintenace instructions (disassembly, where certain items are located, etc)?¬†
I found an antique Powerbook 520C at my uncle's place. I got it to start by randomly pressing button's as none of them sports the universal power swith symbol but it shut down on me... Can anyone tell me where is the power switch on that thing?
I was just wondering since battery life is lower on an MBP running vista, and the MBP is one big heat sink, is there an alternative to SMCfan for vista that works with the MBP? And what is power management like on vista for he MBP? I think i"m finally going to break and get one
when you click on the battery icon and then it lists the battery saver, normal, better preformance list. well mine has disappeared. anyone know how to get that to come back? I hate going into energy saver options just to change stuff around.
So my trusty old Thinkpad crapped out on me last night. I seem to have no power (adapter works, though) so I think the problem is unrelated to the hard drive and that should be okay. I've decided to replace it with a Macbook. In order to get the files off of my completely dead TP--which I'd prefer NOT to put any more money into at this point--can I turn the HD from the TP into an external hard drive and use bootcamp to boot windows from the (now) external HD, then pull files off it it that way?
Also, I read in the Migration sticky that you have to use Windows XP with SP2 and NOT SP1 with an SP2 upgrade. I think I had XP with SP1 and an SP2 upgrade. Even checking out the Windows site, those full versions all only come with SP1. What's the trick?
