Does increasing the RAM reduce or increase battery life?

Recently I upgraded my Macbook Pro i5 13" Early 2011 from 4gigs of RAM to 8gigs. The RAM I used are PNY - 4GB PC3-10666 1.3GHz DDR3 SoDIMM Laptop Memory. I bought them at bestbuy and the "tech guy" said they were fine to use on a mac (and they were.) So I go home and install them. I love the speed boost it gave but the down side is it that it cut my Macbook's battery life down from maybe 7 hours down 5 (That's doing the exact same thing before I upgraded.) I searched online forums and they both have conflicting answers. Some say that adding RAM should improve battery life because the HD get accessed less. (http://forums.macrumors.com/showthread.php?t=1090350) Others say that adding RAM is reduce battery life because it refreshes all the time. I know cheap RAM like these do not come without strings attached, but is it possible that I may have gotten faulty RAM? If so, can you guys recommend the correct kind I should be using? I still have 3 weeks to return them.
Oh on a side note, I was thinking of upgrading to an SSD. Does that also reduce battery life? Here's what I had in mind, http://www.amazon.com/gp/product/B005T3GPXE/ref=gno_cart_title_3
Anyways, that's all.

The answer, I regret to say, can be found in [this thread|http://discussions.apple.com/message.jspa?messageID=11980463#11980463|Th e sad truth about iPod/iPhone battery life].
In order to upgrade this solution from a suggestion by someone who isn't suffering the issue to an account of firsthand experience, I'll tell you that in a household with 2 iPod Touch devices that were both decimated by the upgrade to iOS4, this method cured the battery life of both units and will probably work for you.
+The solution boils down to the following:+
Using iTunes, run the "Restore" to factory settings.
I performed this technological equivalent of ritual sacrifice with full knowledge of the devastation it would wreck on the volumes of settings/passwords/usernames/servernames and countless other bits personal information manually entered over 2 years. I did it partially because I only half-believed it would work and was wantonly hoping for an even greater excuse to complain. 3 days later, I'm still finding information I have to look up and reenter.
+For my own part, I would have greatly preferred the ability to restore my iPod to a state just prior to installation of iOS4.+
Perform this restore at your own risk.
On the 4th page of the thread linked above, +Lawrence Finch+ describes a few less drastic steps you can attempt first if you are equally reticent to give your iPod a lobotomy. I tried them all. A series of acts which served only to prolong the inevitable and increase the amount of time wasted as well as to further inflame my ire.

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.
From what I read, I have 2 choices: 1. to install OSX and then upgrade to Mavericks, but I'm not sure if this would be possible (to upgrade directly from OSX to Mavericks); and 2. to use a software called Super Duper.
I wouldn't like to have to use a third party software to do this, so the question is: is there a better way to install directly the Mavericks not having to use a third party software?

Install the new drive in the computer.
Install the old drive in an external USB or Firewire enclosure.
Boot the computer from the Recovery HD on the external drive.
Use Disk Utility to partition and format the new internal drive.
Clone your external drive to the internal drive.
How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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.
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 is also a good vendor for drives.
Step Three: Boot from the Recovery HD on 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 Recovery HD then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility from the main menu and click on the Continue button.
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.
4. 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.
5. Set the format type to Mac OS Extended (Journaled.) Click on the
      Options button, check the button for Zero Data and click on OK to
      return to the Erase window.
6. Click on the Erase button. The format process can take up to several
      hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Using Disk Utility still opened.
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.

I want to increase the RAM of iMac?

Hi,
I want to increase the RAM of iMac 27"(Late 2013) to 32GB, is it possible to do the same?
If yes, then please let me know the steps to do it.
Thanks & Regards,
Ankush Madan

Yes, you can upgrade it to 32GB, most on this forum recommend two vendors OWC (www.macsales.com) or Crucial. If you are in the USA use OWC, if you are anywhere else then Crucial. BTW here is s link to show how easy it is to install:

HI,
I have checked the kernel-hugemem as:
# rpm -qa | grep kernel
kernel-smp-2.6.9-67.EL
kernel-hugemem-devel-2.6.9-67.EL
kernel-devel-2.6.9-67.EL

kernel-smp-devel-2.6.9-67.EL
kernel-xenU-devel-2.6.9-67.EL
kernel-2.6.9-67.EL
What is the meaning of above output, I mean have already kernel-hugemem rmp installed?
If yes then why the system not using it.
When I had install 24 GB RAM, my OS detect it and also show the RAM 24 GB (checked by free command), but my Database was having high CPU after increasing RAM 24 upto 24 GB.
So, Should I install this rpm "kernel-hugemem-2.6.9-67.EL.i686.rpm"?????

Once you have purchased a MacBook Air with the memory configurationit was built with, it has all the memory it will ever have,
Lesson: Buy with the max memory available. Currently 4 GB.

I came up with a way to increase the bottom line and increase public opinion of Verizon.

When the Verizon customer service staff read script to customers all day, they know all the details... all the small details. The average user does not. Some people use Verizon email for important email, and then other email accounts for less important messages. There should be an option to pay a fee if the average user does not see any reason that Verizon would turn off email. Other companies have email.
Look at the ads for the Discover card in the subway. They read - Discover IT is New, IT is Different, IT is Human. Talk to a real person anytime you want. It will change the way you feel about ________.
What if Verizon changed. What if all the staff of Verizon, knowing that their Midyear reviews are coming suggested change. What if they could say "I came up with a multi-million dollar way to increase revenue." I came up with a way to increase the bottom line and increase public opinion of Verizon.
Give the customer a choice to pay $200 for a one time transfer of email. Then Verizon is a hero and makes money too. Multipy $200 by the number of people who had to give up internet this month and that number has to be big! Put that message on your midyear review. Nobody can tell where it came from. They will only know that you are trying to think of ways to increase the bottom line. Who knows... maybe there will be a raise in it for you! Good luck.

Oh yes, this is great – At last, I can see what I’m trying to do at least. Appreciate your input so rapidly. I jump on the link so rapidly that I failed to notice if there might be a set half this much. I might be able to see it half this much increase like 100% instead of 200%? Oh don’t get me wrong. I’m not complaining, was just wondering – what if…
Thanks,

I'm using LR 5.6. The Enter key should increase the exposure but it increases Contrast instead. How can I make the Enter key adjust the exposure?

Hello
As explained in the heading, I'm using LR 5.6 on a PC (Win 7). The Enter key should increase the exposure but it increases Contrast instead. How can I make the Enter key adjust the exposure, as it should? I have reset the settings to Default in the Develop module but to no avail. Please help! Thanks.
Kind Regards
Farrukh Hyder

I am not aware that the ENTER key should increase exposure, and it certainly does not increase exposure (or any other slider) on my Lightroom 5.6 (Windows 7)
If you click on the word Exposure, then the + and - keys increases or decrease exposure by 0.1 or -0.1

Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.
If this does not help, setting it up as new device without using any backup would be the next step:
Use iTunes to restore your iOS device to factory settings - Apple Support

Does Mavericks have any effect on MBP battery life?

Does updating to Mavericks have any effect on the battery life of the MacBook Pro?

It's suppose to have a postive affect on battery life. At least that's what I'm seeing in comparison to OS X Mountain Lion (Macbook Pro Retina).
See Conclusion at the bottom of this PDF from Apple. You can also skim through the PDF to see how battery life is extended.

How can I get the best out of my battery life?

There are a variety of things you can do to extend your device battery life, and use your phone for longer periods of time to see you through the day.
Set your screen to timeout after a period of inactivity. This way your phone is not sitting idle with the screen backlight consuming extra energy. The recommended screen timeout is 30 seconds, but most phones will allow from 15 seconds to 10 minutes.
Turn off location services (GPS), Wi-Fi and Bluetooth when not using these functions. When they're on, your phone constantly searches for your current location and open networks, which has a big impact on battery life.
Turn down the screen brightness. For example, on an iPhone 4 the lowest brightness setting gives roughly 6.5 hours of continuous use, whereas the highest setting gives roughly 3.5 hours. You can always adjust the brightness when you're outside so you can still see your screen clearly. Some devices have an auto-brightness setting, where the phone adjusts the screen brightness depending on the light around it.
Close your applications. On smartphones, returning to the ‘home' screen only minimises your apps – they keep running in the background. Closing your apps fully will save power; for example, on Samsung Galaxy devices hold down the home button for two seconds to see a list of all open apps. You can then swipe these to the left of the screen to exit them completely. On an Apple product, double press the home button to bring up all active applications and exit from there.

Re: How can I get the best out of my battery life?
Hi,
When I make phone calls people on the other end have difficulty hearing me. They describe as they can hardly hear me as if I was speaking through the pillow etc). I am not touching any buttons and obviously it is not mute. This was happening couple of time in June, then every now and then. Recently it happened a few time in 2 weeks. I was trying to check if it was a reception issue but the place I spoke from is my office I make 70% of phone calls from. Can you book time for me in repair shop and address the issue.
Thank you.

After making a call I put my phone in my pocket and when I bring it out to make a call the player is on killing battery life. How can I shut the player off or prevent this from happening?

Try to position your iphone that the screen is facing away from your skin.
Make sure that the back part of your phone will be the one that will contact your skin inside your pocket
Thats what i do:)
