HT2477 Will a new SSD Drive improve my battery life?

My battery life is too short. There are of course some tweaks I can do that will improve that a little. My questions are:
1) is I would up grade to a SSD drive how much effect will it have on the battery life
2) is there a battery for my MacBook Pro (2012) that would improve run time.
3) any guess what it might to make these upgrades
Thanks,
Bob Hahn

1) I didn't notice any difference in battery life when upgrading from an HDD to an SSD.
2) The batteries that Apple makes are the most reliable (third party batteries are generally junk).
3)Not sure what you mean exactly.  It seems your mac is pretty new and you shouldn't be having battery problems already.  If it is less than one year old, it is still under warranty.

    I have a MAC Pro from 2011 currently running MAC OS 10.9.5.  This weekend I cloned the MAC HD drive to a new SSD drive for improved performance.  The clone was completed successfully with no errors.  After the clone completed I successfully restarted my system using the SSD as the boot device.  I then successfully tested all of my products, including Photoshop CS6 and all of its plug-ins.  I successfully tested the key features that I frequently use.  Today while attempting to launch Photoshop CS6 a message is being displayed indicating that a scratch disk cannot be found.  All drives are available on the system via the Finder and Disk Utility.  I can access all drives including the old MAC HD which is no longer the boot device.  I've even attempted to launch Photoshop from the old device yet the same error persist.  Is there a way to review/edit/change Photoshop preferences if Photoshop doesn't launch?  I've even restarted my system several times to see if that would resolve the issues.  Does anyone have any recommendations for this issue?  Have you previously address this issue? 
    Thank you Gregg Williams

  • I have replaced my old hard drive with a new SSD drive. Can I restore a complete Time Machine backup

    I have replaced my old hard drive on a MacBook Pro midyear 2010 with a new SSD drive. I have a complete system backup of my old drive in an external hard drive using Time Machine.
    Questions that I would like to get answered.
    1) Can I connect my external hard drive to the macbook pro and use that to boot up my machine by pressing and holding down the Options key? Once booted up successfully, can I use Disk Utility to format the new SSD and then restore the complete time machine backup?
    2) If that is not possible, can I use my old drive which I can connect using a USB adapter and use that to boot up by following the same strategy as listed in Step#1 above?
    3) If neither options are possible, do I need to use a bootable USB drive for Mavericks OS X to boot up the machine,
    I have Mavericks OS X ( 10.9.6) and I do not have a DVD of the OS.
    Any help is appreciated.

    Let me first document the steps that did not work and then I will document the steps that worked.
    1) Replaced the hard drive with SSD.
    2) Connected the original hard drive using a USB adapter to the MacBook to make it behave like an external device.
    3) Powered on the machine and on hearing the chime pressed Command-R to start in recovery mode.
    4) Chose the Disk Utility option to erase and format the SSD. The format chosen was Mac OS Extended Journaled.
    5) Once the formatting was done, then clicked on the "Restore" tab in Disk Utility
    6) In the Source field, dragged my original hard drive from the left pane and placed it in the field
    7) On the destination field, choose the new SSD drive. Clicked on "Restore". Gave me a warning, accepted the warning and the restore was under way.
    8) I had 236 GB to restore so took 3.5 hours before it was done.
    9) Disconnected the external hard drive ( my original internal HDD), shut down the machine and powered on again.
    10) Heard the chime and after that it was a white screen with no Apple logo.
    Was visibly upset and started thinking what my next move will be. Then tried these steps
    1) Again powered off the machine.
    2) Connected my internal HDD once more as an external drive
    3) Powered on and on hearing the chime, pressed Command-R as before
    4) Once the OS X utilities screen popped up, this time chose Install OS X
    5) Erased the contents of SSD once more and reformatted it using Mac OS Extended Journaled.
    6) Installed OS X by following the prompts.
    7) Once the OS was installed, I was presented with an option on how to transfer data to this new Mac
    8) Chose the option to move the data from my original HDD.
    9) Took another 3 hours to move the data.
    10) Removed the original HDD once the transfer was complete, powered down the machine and started it once more.
    11) Booted successfully and all my content is now accessible on the new SSD.
    Moral of the story - It is the spirit that counts.

  • My late 2012 mac mini boots slow with new ssd drive

    So here is the situation.  I purchased a 128gb ssd drive, installed it a usb enclosure, formatted it to Mac OS Extended (Journaled), cloned it with carbon copy cloner 3,   used the option key during boot up and selected the ssd drive and it booted my mac mini and it functioned perfectly.  I than tested it for dozens of reboots and it worked fine.  I then took apart my mac mini and removed the original hard drive and installed the new ssd drive.  When I boot to the ssd drive it still takes 47 to 53 seconds just like the old drive.  Aren't ssd drives supposed to be a lot faster?
    My solution or tip is as follows; The reason it takes so long to boot is because the mac mini doesn't know you replaced the old drive and it is looking for it during the boot process.  Finally it can't find the drive so it boots to the ssd drive.  All you have to do to correct this is click on "system preferences", select and click on "startup disk" and select your ssd drive and click on "restart".  After these steps your mac mini will now boot in about 17 seconds.  Issues solved. 

    Yes, my solution fixed the issue.  I went from a 47 to 53 second boot time to a 17 second boot time.  The ssd drive is significantly faster than the original drive that came with my late 2012 mac-mini.   This is my first post and I wasn't sure how to post this as a tip.  I have another tip regarding usb 3.0 hubs. 

  • Should I put the new SSD drive in main HDD bay or the Superdrive/Optical bay for a Mid-2010 Macbook Pro?

    Hello All,
    I'm considering getting a new SSD drive to add on to my Mid-2010 Macbook Pro (13 inches, unibody), and wondering which one of the following two options I should really adapt: 
    (1) Replace the original OEM hard drive in the main bay with the new SSD drive, and then remove the Superdrive (or the optical CD drive) and to be fitted into an external enclosure for using it externally in the future, and then relocate the original OEM hard drive into the Superdrive position, so both the new SSD (preferably for running the OS and system files) and the old OEM hard drive (for storing media and documents for example) could be used; and
    (2) Keep the original OEM hard drive in place in the main drive, and buy a superdrive/optical drive caddy to goes with the new SSD drive, and together place the new SSD drive fitted inside the caddy into the position of the Superdrive/Optical CD drive, and configure the boot preference to be booting from the Superdrive/Optical Drive (which is now the SSD drive with OS and system files);
    I've done some researches and some suggested that option (2) is better approach for at least two reason: (a) the MBP main drive come with some sort of shock proof sensor, so placing the original optical hard drive in the main is better than placing it in the super/optical drive where there is NO shock sensing feature provided, and placing SSD in the super/optical drive, one doesn't really have to worry so much about shocks; and (b) as during the process of shutting down the MBP, for optical hard drive, some power will sometimes needed to finally spin down the drive, but if such optical hard drive is place in the superdrive, the power maybe cut off right away when MBP shut down, which may cause issue to the optical hard drive in a long run as it never properly spin it down.
    Then the main concern is that, if I adapt option (2) above, placing SSD in the super/optical drive bay and install and running the OS from there, will it decrease the performance (i.e. speed, latency, and etc.) as if i was to put the new SSD in the main drive?
    Also, any suggestions with respect to Samsung 840 EVO vs. Samsung 850 EVO (250GB)? any well-rated HD caddy aside from OWC for moving the main HDD to optical CD bay? and perhaps an external enclosure for the Superdrive?  Thanks in advance for any comment and/or suggestion. 
    - Jack

    Could you provide some rationale(s) behind it?  As far as I know, the mid 2010 Macbook Pro, the HDD is running via the SATA interface at running at 3.0 Gb/s, which is SATA II, and the Super-drive and/or the Optical drive, which is also running via SATA II interface, so I would assume the performance (i.e. primarily in speed) would be similar if not the same by placing the SSD drive in either one of the two places. 
    Also, wouldn't it be better by placing the SSD in the optical so the OEM HDD could be kept in the original main bay since it has the shock-sensing feature there?

  • Approach for fresh OSX install to new SSD drive with restore from TimeMachine

    I have an early 2010 MacBook Pro with running Mavericks with FileVault 2 encryption.  The drive seems to be failing.  I am not able to boot it up.  I get a "Prohibitory" sign with freezing.  I have attempted various recovery steps:  booting with Command-R, running Disk Utility, attempting to do a full restore from TimeMachine, turning off encryption via terminal/command line with no success.  I am not able to mount the disk volume.  DiskWarrior doesn't seem to support bootable Maverick volumes.  I don't the the existing drive deserves additional time.
    I've purchased a new SSD drive and I plan to do a fresh OS install on that drive, followed by a restore of my most recentTimeMachine backup to that drive.  My backups are not encrypted.  Because the current HDD seems to be toast and is running FileVault 2, installing from scratch and then restoring apps and data seems to be the most realistic approach.
    Can somebody please tell me what the preferred sequence of steps would be to do this?  Particularly the initial OS X install?  Since the new drive will not have a recovery partition, I assume that I cannot do Command-R at boot-time to start the install.  My system has a DVD drive, but I don't have a Mavericks install disk.
    Comments appreciated...

    Restart the computer. At the chime press and hold down the OPTION key until the boot manager appears. There should be a disk icon for your Time Machine backup drive. Select it and click on the arrow button below it. This will start you into a hidden Recovery HD on your Time Machine backup drive. Select the Disk Utility option and click on the Continue button.
    1. After DU loads select your SSD (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    2. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
    3. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    4. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    5. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    6. Quit Disk Utility and return to the main menu. Select the Install OS X option and click on the Continue button.
    7. Be sure to select your SSD as the installation target.

  • I installed a new SSD drive in my computer and now Adobe Creative Suite Web Premium says I don't have a license. I have license. It was very expensive. I am disabled now, and I need this software working.

    I installed a new SSD drive in my computer and now Adobe Creative Suite Web Premium says I don't have a license. I have license. It was very expensive. I am disabled now, and I need this software working. Adobe Acrobat has been a primary tool for accommodating memory problems after a brain injury. (A car ran me down while I was out getting exercise.) I installed the SSD because I needed my management of PDF files to run faster. I called tech support for help when the software first stopped working, but they needed me to give them a number from my original disks. Because of my disability, I've been having someone come in to clean, and the shelves where I kept my software packages were cleared. I've been hunting for them ever since, but I can't look for them myself for very long at a time. Today I finally found them, but now I can't seem to contact tech support. What happened? I don't want to delete my old files because I need the setup to remain unchanged, because I don't do well with changes. I think all I should need is to have someone located the license file on drive E: and move it to wherever it is needed on the SSD drive, but I don't know what to look for.

    Tech support is not normally available on weekends.  You should contact them as soon as the weekend passes and pick up where you left off with them.

  • Do I have to activate AHCI mode on a Mountain Lion after a new SSD drive installation?

    Hello All,
    Do I have to activate AHCI mode on a Mountain Lion after a new SSD drive installation?
    I have a new Corsair GT SSD sata 3 drive on my mack book, I have read on corsair web page that is good tho activate the AHCI and TRIM but I cant find information about how to do this on OS X.
    Thank you all

    That's information for non-Apple hardware. You can activate TRIM using third-party software: TRIM Enabler 2.2. However, most new SSDs should not need TRIM activated on the Mac.

  • How can i improve the battery life of my iphone 5s, it drains to fast and i don't know what to do?

    http://www.apple.com/batteries/iphone.html
    Take a look at this to make sure your settings are optimized to the best it can be.
    If all else fails, try and restore through iTunes, set up as a new iPhone and manually sync your apps and media back to your iPhone.
    If still persists after this, you might call Applecare and see if they can run a battery diagnogstics..

    The camera can be focused by take the point of focus on the touch screen.
    If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

  • My hard drive is fried.  I need to reinstall moutain lion to a new SSD drive.  How do I install without media?

    My hard drive fried.  I can't reinstall from the OSX utilities because it only shows the recovery partition.  I was thinking about adding an SSD drive.  But I dont know how to install OSX mountain lion without any media.  What are my choices?  What should I do?

    First, the recovery option is built in to OS X - not the disk. If you install the new drive without formatting it first or without having an OS on it, it will not work (at least as far as I know). Most drives need to be formatted and it needs to be Mac OS Extended (Journaled) and use the GUID Partition Scheme.
    You said that your hard drive is fried but that you can access the recovery? The Command + Option + R is the internet recovery which means it accesses Apple's servers and a limited number of things including disk utility. I've not dealt with this type of problems, so I'm not sure, but If you can access that and you have your new drive in an external enclosure and attached, then you may be able to use Disk Utility on the recovery to format your new drive and then choose to install the OS directly on it.
    The second possibility - and, according to the following article, this should work directly (I've not tried it, so I can't guarantee it will):
    http://support.apple.com/kb/HT4718
    The easiest way would be to attach the new drive in an enclosure and use your internal's disk utility to format and then clone the entire thing to it, but that does not appear to be an option. Unless...... do you have a bootable clone backup or a Time Machine backup?

  • Boot Problem with new SSD Drive on CQ60-409SA

    I have just replaced my HDD with a new Sandisk 120GB Extreme 11 SSD.
    All went OK with no problems installing Win 7 Ultimate and much faster search time, etc..
    The problem I have is that when I boot the laptop from cold, i.e switch it on for use, the SSD is not recognised and I just get a Black screen with Flashing cursor top left corner, but if I then press Control-Alt-Delete, the system Reboots, and then boots into windows no problem.
    I am trying to find out if I can Access BIOS Advanced Options, if I press F10 during boot I only get Options like Change Boot order, and not more Advanced Option to change Drive parameters, etc... and F2 does not run Diagnostics for SDD.
    Any help would be greatly appreciated as I am very pleased with the performance increase the SSD drive gives to Windows and Boot itme except for having to boot twice.
    Best regards,
    This question was solved.

    No worries.
    What year model is your notebook?
    About your request for the Advanced options, unfortunately that is not possible with a BIOS supplied by HP.
    You can, if you don't mind taking the risk, go to a BIOS Mod forum and look for a modified BIOS for your notebook there. The modified BIOS will have advanced options.
    Have you tried the Solution and Update finder on the Support download drivers page for your notebook? It says that it will find missing drivers.

  • Best way to migrate to a  new SSD drive for performance and reliabilility

    Hello all,
    My 2011 15" MacBook Pro is about 3 weeks old and my new OCZ Vertex 3 120GB SSD is coming in tomorrow.
    What is the best way to move my system over to the new drive? I have Time Machine backups on my external Firewire drive as well as complete drive images made with CCC. I have read where some have had problems cloning to a new SSD using a drive image.
    My plan is to format the drive and install the OS with the cd then move my applications and files over with Time Machine but it would be much easier to just clone the existing drive image but I don't want any problems down the road. What is the best practice?
    Thanks.

    Follow this outline:
    +Step One+: Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Quit and shutdown.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    +Step Two+: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who are also a good vendor for drives.
    +Step Three+: Boot from the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive then click on the downward pointing arrow button.
    +Step Four+: New Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your new hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    +Step Five+: Clone the old drive to the new drive
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4.Check the box labeled Erase destination.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    Destination means the new internal drive.
    Source means the old external drive.
    +Step Six+: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

  • Reinstall new ssd drive from time mechine

    how to reinstall my new blank internat ssd drive via time mechine..

    How old is your Macbook Pro? If your model is on the list you can boot from internet recovery (start computer and hold ALT+CMD+R). Other way is to use Recovery disk assistant but that will need to be prepaired before you replaced drives.
