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.
if I want to connect the macbook to an external LCD monitor, I will need a mini-DVi to DVI adapter, but the adapter is so short. So should I connect the adapter to the DVi cable that is connect to the monitor? The adapter is so short that there is no way it can be directly connected to the monitor......
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 Dell Inspiron 1520 and my friend has a Latitude D820.
Tonight she accidentally plugged my power adapter into her laptop. A few hours later, she noticed that her laptop indicated that it wasn't plugged in, and that's when we realized that she had accidentally used my adapter instead of hers.
Now my adapter doesn't work at all. We've tried the adapter with both our laptops with different outlets with the same problem, so we know it's the adapter. The green light also doesn't come on when it's plugged in anymore.
Did plugging my adapter into her laptop somehow screw up my adapter, or could this just be a coincidence? Is there any way to fix the adapter or at least figure out what the problem is? And if I have to purchase a new adapter, do the universal ones they sell at retail electronics stores work OK? I would order one from Dell but I'm working on a project now and I don't have time to wait for it to ship.
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 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?
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).
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.
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.
I've got a new power adapter which is 65w. When I plugged it a warning message popped up saying Im using a 65w adapter and my system will operate slower and that my battery will take longer to charge.
The part with the battery taking longer to charge I get but does my system will really work slower ?
I really would like to get two of these, since they are less than 1/3 of the price of the adapters I can get in Norway, but I'm a bit suspicious.
The original adapter for my Precision M6500 is 210 watts (which is totally crazy, but I guess the Fire GL card eats most of it), and this is rated at 90w. But will it even work? Here's the eBay auction, it's in Great Britain:
I just received my e6400, and it is now charging the battery. The ac power adapter is very very hot, is that normal? Should I ask them to change one for me?
how the power adapter of the Studio XPS 13 looks like, because the size of the power brick is essential to me. Although you can buy a separate one but that would be a waste of money.
So my question is, what's the difference between the 65W power adapter and the 95W power adapter? This is because choosing the Geforce 9500GE online would change the power adapter from 65W to 95W.
Why is this anyway? Isn't the 9500GE suppose to save more battery than the stock 9400GS?
I have the Aspire 1410 -2285 with Windows 7 and the Celeron SU2300 Processor. The AC power supply clearly shows the specifications as 19 volt, 1.58, amp, 30 watt. I want to purchase another adapter but everywhere I search lists the adapter for the 1410 as 19 volt 3.42 amp and 65 watt. This include Amazon. Can I use this AC adapter with this computer.
I've been thinking about buying a new power adapter to replace el-giganto that came with it. I understand that there is at least one Kensington power adapter that works (model 33197). That one, IMO is a bit too large. Curiously, that adapter is not directly visible on Kensington's website for Laptop Power Adapters, but is searchable (by part number).
So my question is whether there are any people out there that have used, for example, the model 38066 or the model 38067 successfully? Those two models are smaller (physically) than the 33197, but they don't actually list the Wattage they provide (they're listed by Voltage and Amperage - which kind of makes Wattage, but not exactly). It seems as though they might be 90W adapters (as the product pages make continual reference to their power efficiency over "other 90W adapters" which leads me to believe that they're probably around 90W adapters.
Or whether the model 38031 or 38030 will fit? These adapters are a bit larger, but appear to offer more input amperage. Though they also say "Up to 90W output" so ...
From what I understand, the HP Envy 15 will throttle the machine with less than 120W of input wattage.
I am in need of a new AC adapter for my HP Envy 15. Can any of you veteran owners recommend me a reliable and quality one (and hopefully under $100), preferably with a decently long cord?
Have had my xps 16 for a few weeks. my power adapter is making some strange sounds. It's kind of like a really light fizzy/crackling sound. The best way to describe is that it sounds like a soda/carbonated beverage. Not all the time, just sometimes. I thought it was just random, but I was using it earlier, and noticed it made the sound when I was doing some task on the computer, i.e. scrolling down on the touchpad, or opening a folder, etc....????
Anybody experienced this? It's the 90W adapter, and I was going to call Dell and get the 130w anyway, but does anybody have any thoughts?
How do I tell if mine is 130 W or 90 W? I have 2 adapters: the 1st came with my older 1640 and says 90 W on the front, while the newer one that came with my 1645 does not say anything related to W. The part # is WK890 and everything else is about Amps, Voltages, Made in China, etc.
