Powering MacBook only with power chord?!?

Is there a way of using the power chord without recharging the battery simultaneously? I asked at future shop and they suggested to simply take out the battery while using the power chord, but in doing so I am exposing parts that are simply not meant to be exposed. Is this a good solution or is there an option on the computer that I have simply not seen that will enable me to do so?!?
MacBook Pro Mac OS X (10.4.7)

I have read a lot about shortening the battery life of a lithium ion battery by having it always charged...cycling is good. Is there a type of technology in the MBP that will prevent deterioration of this sort or is it still applicable? Thank you.
Apple have an extensive KB article that deals with advice and tips on how to keep you Notebook's lithium-ion battery in tip-top form.

Palm TX works only if power chord is plugged in, crashes if i take the power chord out

Hi,
I brought a new Palm TX in 2008. I never used it because I was busy with work and it was never used. I recently found it when cleaning my storage. I tried to charge it for 2 days continious. As soon as I take the power chord out, Palm TX crashes. It comes back up again only if I connect it to power supply. Does not work all by itself.
Sincerely
Sudhi

The battery is dead. There are many places online that sell batteries and do the repairs at nominal costs.

How to wake from sleep only with power button

Hi,
I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.
Unfortunately my cats like to touch the keyboard, thus waking up my Mac.
Is it possible to wake the mac only by pressing the power button?
If so, how?
regards
kpgkpg

The USB bus is unique from other buses in that it always has power present to it.
Because of this, it can be used to sense activity at a keyboard or other input device to facilitate wake from sleep.
The power button also always has power present, with the main purpose of on and off being extended to options for sleep and wake. This is possible due to the use of a momentary contact switch, with fuction that can be interpreted (time held) for various purposes via software.
why the action on the USB bus has to be a keyboard inpput, but not a mouse click. strange.
Mouse click should also wake the machine if the mouse is USB. If Bluetooth, an option must be selected in the software, and then not all mice are equal.
If wireless, then, again, not all are equal. Some will wake a machine, others won't.

Powermac G4 : Wake up only with Power Button

My Mac used to wake up with just moving my Logitech USB Mouse until the fans went haywire. Now only by pressing the Power button, does the Powermac G4 wake up. Fans have been changed, Hardware test and Memory test have been run, still no change. Any suggestions how to restore the wake-up to previous state. Thanks.

whether using NVRAM or PRAM, the Powermac G4 reverts to Panther on restart. I am told this is normal.
That sounds like a dead or weak PRAM battery. "Normal" is that the computer remembers its startup volume settings. Are you unplugging the computer from wall power? What you see can be a symptom of having a dead PRAM battery combined with pulling the plug out of the wall every night. Turning off a power strip of backup power supply has the same effect.
There are a number of G4 variants and I've not yet seen a mention of which G4 variant you're working on. The later Mirrored Drive Door G4s do better with both drives set to cable select. The older variants retain the older "master/slave" relation for drives. Do "About the Mac..." then click on "More Info..." in the resulting window. Copy/paste the "Hardware Overview" info from the next screen into a post here, deleting your serial number. That screen for my G4, an MDD, looks like this:
Hardware Overview:
Machine Name: Power Mac G4
Machine Model: PowerMac3,6
CPU Type: PowerPC G4 (3.3)
Number Of CPUs: 1
CPU Speed: 1.25 GHz
L2 Cache (per CPU): 256 KB
L3 Cache (per CPU): 1 MB
Memory: 1.75 GB
Bus Speed: 167 MHz
Boot ROM Version: 4.4.8f2
Serial Number: <deleted>
That might help us work througha n model-specific issues.
What kind of keyboard do you have the requires USB 2.0? Most are slow devices and more than hapy on a USB 1.1 port.

My MacBook Pro's battery is completely dead and even with the power chord attached it doesn't turn on. Any solution ?

I read somewhere that even with the drained out battery the mac should work with power chord attached. In my MacBook Pro 8.1 (late 2011) the green battery indicater on the side of the laptop just blinks depicting that the battery is dead. But the mac is not turning on even when the power chord is attached. I don't mind working with the power chord all the time but at least the MacBook should turn on. When I press the power button I hear nothing, I see nothing , there is no change. It's just a dead laptop. I am worried. Is there something else wrong with my MacBook Pro

Ok...I'd be tempted to try another charger if you have access to one. If not, I'd book a Genius appointment at your nearest Apple Store & get them to take a look for you.
Good luck.

My HP Compaq powers on only when force i plug in. Doesn't turn on with power button!

I have a HP Compaq 6710b.. Its Over 6 yrs old..
The Issue is really annoying.. The laptop powers on only when i force plug in the charger pin and the laptop works fine after that..
But the laptop never turns on when i try to power on by pushing the power button!!
I couldn't understand the reason why...
Any thoughts about this issue? HELP!!
This question was solved.
View Solution.

There are no settings in the BIOS that affect the use of the power button.
The power button works at the hardware (firmware) level.
Pressing the button is translated into action for the system board by logic conditions. There must be voltage at specific points in the power circuit. If the voltages are not present, then the power button will not operate. This could be caused by a failed resistor, mlcc capacitor or a faulty solder joint, if the power button has been tested and shown to be working normally. Even lint could cause this to happen. This can troubleshot by visual inspection and use of a multimeter.
Hi all,
This may be a solution for others but unfortunately not me..
My whole Power Circuit has been replaced with brand new circuit by authorised service personal in my country (will not HP, but he is an authorised service dealer of HP).. It was replaced/repaired a year ago and after that i hardly would have used the power button.. I also use the sleep mode and mouse to wake up.. (would have used power button not more than 20 times in one year. And especially during update shutdowns)..
So its better i will check with BIOS/CMOS setting and battery and get back soon.. Why i am mentioning this is because, for the past 8 months, when even i remove the battery and put back in and start up the lappy, the date goes back to 1980.. I guess this happens because of faulty/dead CMOS battery.. Because i had a similar problem with my Desktop too and when i replaced the CMOS battery, the date problem on my desktop vanished.. (Surprisingly, even some Digital cameras hav this issue too!!)..

Reset the SMC, then test your MacBook Air again.
Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset:
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

MacBook Power Chords

Is the power chord for the MacBook Pro (2009) interchangeable with the power chord for the MacBook (solid black) version?

The 60W power adapter that came with any MacBook will properly support any 13" MacBook Pro and the 15", 2.53GHz mid-2009 MacBook Pro that has only one GPU. All larger and faster MBP models, and all 15" late 2008 models regardless of speed, require an 85W adapter to function normally.

Any way to power on macbook pro with external wired keyboard without opening the lid?

Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
There are only two practical differences between Sleep and Shut Down:
1. Sleep will wake instantly, so you don't have to wait for startup.
2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

Charging Macbook with Macbook Air's power adapter

I have noticed that the power connector on the late 2008 aluminum Macbook accepts the Macbook Air's power adapter's plug. The Macbook Air's power connector also accepts the aluminum Macbook's power adapter's connector. So, can these power adapters be used interchangeably? The output power specifications are a little different. The Macbook Air's power adapter supplies voltage that is a bit lower than the aluminum Macbook's.
The reason I am asking is that if my wife and I both travel with our laptops (she has Macbook Air and I have the new Macbook), it would be nice to be able to bring only one power adapter and use it with both laptops. I have also noticed that the airplane power adapter shipping with the aluminum Macbook (late 2008) is the same one that I bought for my wife's Macbook Air. However, according to Apple, the airline power adapter does not charge the battery, but only powers the laptop.

It is safe to use your macbook power adapter on the macbook air, but not the otherway around. The macbook air power adapter won't supply enough power to the macbook and probably will overheat and eventually burn out (if not worse).

What is the problem with 15-inch Macbook Pro model 2011 after connecting to TV with HDMI chord?

Today we connected a 15-inch Macbook Pro model 2011 with HDMI chord to an Insigna Television. We plugged and unplugged couple of times. But recently the macbook pro is having technical issues. The following symptoms are:
1. Macbook pro turns on and off
2. The screen stays blue and keeps loading but does not load to the desktop so you can't access to anywhere
3. The screen sometimes becomes fuzzy and the apple logo that shows before it loads to the desktop is fuzzy
4. Sometimes fuzzy lines appear on the screen like you see on television when there's a bad signal
5. The screen stays blue
6. Sometimes little specks appear on the screen
Only thing we did was turn it off and restart but it still leads to the same symptoms above.
Does anyone have any clue what caused this problem? I am guessing it is due to the connection to the HDMI chord, since we didn't turn the macbook on and off when we plugged it, rather we just unplugged and plugged the chord while the macbook is running.
Another theory might be watching movies from an online source but the first theory seems to make more sense.
We scheduled a meeting with the genius bar tomorrow but does anyone might have any clue? And also any ideas how to fix this? This is an emergency because there are important files on the macbook we didn't back up and we hope the files are safe and we need to use the macbook ASAP. Let us know anything that might have caused this and/or any solutions or help. That would be appreciated and thank you.

Hey there! Welcome to the Discrete GPU issue clube ... post your relate here >>> 2011 MacBook Pro and Discrete Graphics Card
And for GOD SAKE! Call Apple to tell them that you're another user with such problem ... that action can improve a future recall. BTW the fix price for your problem is around U$ 1000,00 ... that's the meaning of the recall attempt

You have to remove all cables before connecting to your computer with micro usb. Power is only connected when using a 3rd gen device and done after the initial connection.

I have purchased a macbook air with 64 gb hard disk. the available space is only 10gb. With this available space, i can't use the system effectively. kindly advise.

I have purchased a macbook air with 64 gb hard disk. the available space is only 10gb. With this available space, i can't use the system effectively. kindly advise.

You should have bought one with a larger SSD. You can regain some space by disabling the sleepimage file:
To disable safe sleep, run the two following commands in Terminal:
$ sudo pmset -a hibernatemode 0
$ sudo nvram "use-nvramrc?"=false
When done, restart your computer. Now go delete the file "/private/var/vm/sleepimage" to free up some hard drive space. When you put your computer to sleep it, should happen in under five seconds; my MacBook now goes to sleep in two seconds.
[robg adds: To state the obvious, with safe sleep disabled, a total power loss will wipe out whatever was open on your machine. To enable safe sleep mode again, repeat the above commands, but change hibernatemode 0 on the first line to hibernatemode 3, and =false to =true on the second line. You'll then need to reboot again. Personally, I prefer the safe sleep mode, even with the slower sleep time and hard drive consumption -- even if for no other reason than it's great when changing batteries on a flight.]
You can also delete unneeded files:
Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion's Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

Macbook Pro?? Use on a power chord or battery?

Hi,
I have recently purchased my first macbook and was wondering whether it is better to use the power chord as much as possible or use the battery or both in a combination? if its a combination a approximate ratio would be appreciated, apologies if it's a noob question.
Thanks

The battery will be good for a certain number of discharge/charge cycle equivalents, where one cycle is a near-complete discharge followed by a near-complete charge. minor discharges and recharges only count for a partial cycle.
If you have power available, plug it in and your Mac will be faster and the battery will last longer, except: be sure to run it down a little at least once a month.

I have a newer MacBook Pro with an AMD processor. It is my understanding that Parallels can only be used on Mac's with Intel Processors. Is that true and if so does anyone have recommendations about how to have a windows side to my Mac

Then it either is a pirate clone or you are misinformed.
Apple Computer has never used AMD processors in its products.
However, the Graphics Processing Unit (GPU) is a Radeon unit, which is an AMD subsidiary. Parallels, VMWare, VirtualBox will all work fine with the Intel Core i7 or i5 CPU that powers the Mac, and use the AMD Radeon GPU that drives the displays.
