MacBook Pro will not work without external powersource

Hello all,
I have (and love) my MBP. I've never had issue with it until tonight. My battery is at 100% charged, but when I unhook the Magsafe power source, the MPB shuts off instantly - and will not spool up until it is plugged back in.
Any ideas?

Check your System Profiler (Apple menu > About this Mac > More Info, click on Power). Post the Battery Information and Charger stats here, please.
Here are mine, for example (currently on battery, need to plug in soon):
*Battery Information:*
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 5825
Remaining Capacity (mAh): 1211
Amperage (mA): -1972

Macbook Pro will not recognize my external hard drive

I just updated to a newer MacBook Pro. I ran Time Machine on my old Macbook from a 2TB external USB hard drive. When I hooked the hard drive to my new Mac, it wouldn't allow me to select it as the drive for Time Machine. So I dismounted the hard drive and hooked it back to my old macbook to see if it still registered there (which it did). Now when I try and hook the hard drive to my new macbook, it will not recognize it at all. First question, why will it not recognize my new macbook, and second question, why does Time Machine not recognize the hard drive? It has my old time machine files on it...hopefully I don't have to reformat it and lose all my backup??

My hard drive is now connected. But Time Machine will not let me select the hard drive as my back up drive. This hard drive was used on another Macbook, so Time Machine doesn't seem to recognize the hard drive on the new one. Do I need to reformat the hard drive? I hate to do that because I have the previous backups on there.

DVD player on Macbook pro will not work

I have a couple of problems with my Macbook pro:
1. it will not recognise any devices all of a sudden i.e my camera
2. DVD player will not work and keeps coming up with an error message.
please help

Help us help you by posting more info:
MacBook Pro variant and screen size (there have been many since the MBP was introduced 8 years ago)
Mac OSX version
If the DVD failure with burned disks or commercial DVDs? Will it mount a commercial CD?
If you don't know your MBP version and your OS version is 10.7 or higher, you can get it by doing "About this Mac" from your Apple menu and, in the resulting window, click the "More Info..." button to get this:

MacBook Pro will not shutdown with external HD Screen

I have been working with the same configuration for over a year with no problems. I have an external 20" HD screen that I use with my MacBook Pro (cover of mbp is closed not dual screen use) and an external keyboard and mighty mouse. Ever since upgrading to Leopard, when I select Shutdown from the apple menu the computer goes through the shutdown process and the screen goes dark. When I go to unplug the monitor and keyboard the front light is pulsing on and off like it is in sleep mode and NOT shut down. I open the cover but nothing happens, I try to wake it up but it won't wake up. I can hear the fans running and even after 20 minutes in this mode the bottom feels hot so it is as if the processor is working.... I usually have to open the lid and hold the power button for 5-10 seconds to actually get it to shut down... Anyone else having this problem or know what it could be?

I have exactly the same problem. Moreover when trying to wake up my Macbook Pro 15 inch (bought end October 2007) running Leopard 10.5.1 after use with an external screen, at work and at home, it wakes up but I often loose keyboard access, both internally and externaly, and both external and internal screens go black. Under these conditions the computer starts heating up and the fans start spinning. The only possible intervention left is to reboot the machine. This has already led to two hard disk crashes and a motherboard being replaced (all within two months), but the issue continues. Now, I noticed the following: when I boot the MacBook Pro by pressing the power switch while it is connected to an external keyboard and screen and I close the lid, it boots normally into one of the user accounts. When I now switch to another user account the external screen presents the additional window without the menu bar (mouse is active) as if the the primary window (with the menu bar) would be presented on the internal screen. However, when I open the lid the internal screen remains black. The new user account is active though since mail messages come in as normal with a beep. When I want to force the Macbook through a sleep and wakeup cycle to activate both screens they stay black and I loose all keyboard and mouse control and I have to reboot. After all this I am afraid to reboot and force a third disk crash. Has anybody experienced the same, or a similar, problem?

MacBook Pro will not run my external monitor

My External monitor will not come on with my MacBook Pro after I installed Mountain Lion. I get the wallpaper but that is all. Any ideas? I have been running the Mcbook Pro with the cover closed with the external monitor, with no problems up until I installed Mountain Lion.

My hard drive is now connected. But Time Machine will not let me select the hard drive as my back up drive. This hard drive was used on another Macbook, so Time Machine doesn't seem to recognize the hard drive on the new one. Do I need to reformat the hard drive?

Macbook Pro will not recognise WD external hardrive

Hello,
My hard drive, which has all my time machine back ups on it, just stopped working. It was working fine last week when I last backed up, however when I plugged it in to my macbook pro today my computer would not recognise it. I am quite worried as my hard drive has all my files and photos on it.
I believe the model of my hard drive is a WD 1TB external hard drive, and it is a few years old. I have never had any problems to date.
When I tried to use disk utility though, it picked up the hard drive in there but said it needed to be repaired but would not repair it.
Can anyone tell me how I can fix this or what my next steps should be?

First see if another computer recognizes it. If not, it's possible the drive is still good and the circuit board in the drive housing has failed. That's relatively common. If that's what it is you need to get the actual drive out of the WD housing and into another external enclosure. Something like this:

My 2011 i7 15" Macbook pro will not work with hardware virtualization

I have a Mac Book Pro with an Intel i7 2.66 MHz chip and it will not support Hardware Virtualization. When I try to create a Virtual Machine in VMware Fusion it fails with the error that my MBP does not support "Hardware Virtualization".

clivefromcape town,
replacing a hard drive is one of the easier “surgeries” to do in a MacBook Pro; it really isn’t difficult.
Regarding my opinion on HDD vs. SSD, I have a Mid 2010 MacBook Pro, and I did a SSD “transplant” on it this past autumn. I’d chosen the 512 GB Samsung 840 PRO SSD; a major selling point for me was its five-year warranty, which I’d interpreted as being representative of Samsung’s best estimate of product return rates. Other people here have good things to say about the Crucial SSDs; I’ve never had one, so I can’t comment on them. My MacBook Pro certainly boots up faster and loads programs faster because of the SSD, but a SSD will not make programs run faster unless a program’s performance bottleneck is with disk access; most programs will not have such a bottleneck. Your recent RAM increase will probably help more with program run speed than a SSD would. That being said, I neither watch movies nor listen to music on my MacBook Pro; perhaps a SSD would help with movie playback, since that might be an example of a disk-bound program.

My MacBook Pro will not start without the charger plugged in despite saying not charging and with a green light!

I have done a system report that says that my battery is normal. What should i do next? Thank you!

LEH65,
have you tried resetting your MacBook Pro’s System Management Controller?

Macbook Pro will not boot on external Firewire drive. Mybook with 2 partitions containing 2 OSX images using CCC. Volumes will not display when booting but do display when the internal drive is running OSX using Startup utility.

Any comments are greatly appreciated.

Applejack is just a command-line "front-end" for a number of different command-line tools you can use in single-user mode, and I'm not sure whether it's Lion-compatible. You can always try booting into single-user mode and executing:
/sbin/fsck -fy
That's unlikely to solve your problems, though. Since you can't boot from two different hard drives and your optical drive, that indicates there's a more serious hardware issue, or multiple hardware issues.

I have a late 2008 Macbook Pro, I am trying to run MW3 but it will not work without crashing a few minuets into the game. The general specs on my computer are a dual processor 2.53 ghz. 4 gb ram and a NVIDIA geforce 9400 (9600 is the alternate card)

Things to note:
I have been unable to update firmware on this computer for about a year now. Im not sure why.
I am running a bootleg copy of Windows XP on this computer, I would not like to spend $149 to get Windows 7 if possible.
any thoughts on the matter would be greatly appreciated, thank you.

Why don't you take your 'old' MBP into your local Apple Store and have them check out everything that's wrong with it - and I mean everything? Then, when you get an estimate about how much it would cost to get the machine completely repaired, ask about the Apple flat-rate repair pricing?
It's worth a shot - and with what you may save, you can put in the bank for a new MBP.

My MacBook Pro will not connect to my home wifi but will connect everywhere else. My other Apple devices (I-pad, I-touch, another MacBook Pro) connect to the router without problems. It was working fine but all of a sudden stopped working.Thanks!

try this.
get back into your router's settings and start deleting devices that are not connected to your router.
you can also delete the ones that are connected - they'll connect again.
on the DHCP side of it, increase the amount of users that can connect/log in to your router.
see if that sorts it out for you.
good luck.

The MacBook Pro will not allow me to cut-and-paste to and from or to click-and-drag to the external drive. I can copy-and-paste, but then I must send the original to the trash, which doubles the time and effort. Is there any way to cut-and-paste?

I have recently switched from a PC to a MacBook Pro.
I have a large number of documents and photographs on a multiterrabite external drive, backed up on a second multiterrabite external drive.
Both external drives are formatted for MacIntosh. This has been verified by agents at an Apple store and also at Best Buy in two different cities.
This is the problem:

Also, the MacBook Pro will not allow me to rename multiple documents or photographs. I can click-and-rename a single one, but this is impossibly time consuming. I can batch-rename in iPhoto, but when I transfer the photographs to the external drive, the rename does not transfer.
I’m reduced to using my wife’s Toshiba to cut-and-past, rename, and transfer documents. It works perfectly. Is there any way to do this on the MacBook Pro?
Thanks!

No, this is a philosophical difference between Apple and Microsoft. Apple believes that it's dangerous to cut a file in case the user never pastes it; in that case the file is lost. Microsoft seems to not have this problem (if I remember Windows correctly) because they don't delete the originating file if it's cut but never pasted.
Even though Macs have a lot of keyboard shortcuts, philosophically Macs have traditionally been mouse-first. This applies to file copy operations. In your case, what a Mac user would do is open the source window, open the destination window (on your second drive), and then Command-drag the selected files from the source to destination window. This is because a normal drag would leave the originals behind, while adding the Command modifier key tells OS X that this is a Move, not a Copy, so don't leave the originals behind.
(In addition there are different rules for drag-copying within the same volume or between different volumes. If you drag between two folders on the same volume, the files are moved. If you drag between different volumes, the files are copied unless you hold down Command to delete the copies on the source volume.)

Two problems in this case. First, batch file renaming is not built into OS X unless you build something with Automator. However, there are many utilities that can do batch file renaming which you can find at macupdate.com or on the App Store. Since I work with media I often batch rename using one of the media managers I have lying around like Media Pro or Adobe Bridge (comes with Photoshop).
iPhoto is a database front end designed to shield the file system from the consumer and let them concentrate on creativity and sharing. As such it is often a poor choice for managing files directly. When you "transferred the photographs" chances are you moved the originals, not the ones iPhoto edited which are stored in a hidden folder.

There will not be a way to do it exactly like Windows. As described above, there are ways to do it "the Mac way." If it is possible to remove judgment on which way is "better" you might find the Mac way to be acceptable, but of course sometimes we simply prefer what we're used to.

My macbook pro will not recognize my WD external hard drive 1tb

My macbook pro will not recognize my WD 1 tb external hard drive that I have as my time machine backup. I worked just fine for a long time now The only way I can see it is through Disk utility. And when I try to repair the disk it say it cant be repaired, and i need to back up files and reformat. All my backups are on the hard drive. How do I back up the back if I cant get it recognized? Uggghhhhh I have several years of info on the hard drive .. PLEASE HELP!!!

Hi cterry66,
Welcome to the Apple Support Communities!
I understand you would like to reset the user account password on your computer but do not know the original password. If you set up your Apple ID with that user account, you can use that Apple ID to reset your OS X user password. Please use the information provided in the attached article to complete the process.
OS X: Apple ID can be used to reset your user account password - Apple Support
Cheers,
