I have 8 gb on my macbook pro, but it sometimes only recognizes 4 gb. Whats going on?

I have 8 gb on my macbook pro, but it sometimes only recognizes one of the banks and thus only 4 gb. I was about to open my Macbook Pro mid 2010 2.66 up but it went back up to 8 gb of ram.
I also noticed that the macbook would go to sleep and not wake up again, sometimes. Not sure if this is related.
I did the usual, resetting the PRAM and the other thing with "shift control option." It didn't work and kept on saying 4 gb.
I woke up this morning ready to break open the mac when it read 8 gb. Great! But the **** is going on. Is that memory slot loose?
My google search and search through these forums were useless, no solutions. One guy tried changing his memory into the two banks, no difference. Sometimes it recognizes bank 1 sometimes it doesn't. Another put his ram in another computer, it's not the ram. Someone suggested the motherboard, then someone said "no way" for some arcane reason.
The only solution that seamed viable was going back to snow leopard, the last great OS. Im on mountain lion, not to shabby, but no leopard.
Problem is that I am out of warranty.
Any suggestion would be helpful.

why don't you try this:
open the back of your Macbook - if you're technically capable...
take the ram out, clean it up with a pencil eraser - blow it out - put them back in, slowly and in a slight angle until they lock into place - make sure they are seated correctly...
restart your macbook - if the same bank is still not detecting - then the issue is your RAM slot...
good luck

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem?

My Macbook pro, (late 2010) sometimes will sleep and won't wake up. then the sleep light flashes.What's the problem

Hi I've been following this thread (along with a different one on the same topic). I've been having the same problem with my ibook. I can add that I have no problem with startup. It's just that the screen "goes to sleep" unexpectedly and may operate normally for a few minutes or a few hours at most. Opening and closing the lid or restarting seems to cause it to awaken but then usually for just a few seconds or minutes. If it is connected to another video display that display continues functioning fine even though the computer screen is blank. In addition the desktop is there and visible faintly or if totally blank can be backlit through the apple logo and can be read. I've had my logic board replaced twice under the extended warranty and assumed it was that but now I'm thinking of the reed switch. Apple refuses to consider any further work under warranty as the last repair was in Jan, 06 and they claim only a 90 parts warranty and the machine is from 03. Any thoughts before I cut the wires? I have reset the pmu, run cocktail and disk utility. Other than the sleep issue the machine works fine. thanks Ronda or anyone else who has any ideas... Dave

I see that i have a problem after installing my new hard drive on my macbook pro mid 2009 version. I put a new hard drive, with all of my information from my old drive installed on it, into the computer. but now have the blinking question mark folder

i see that i have a problem after installing my new hard drive on my macbook pro mid 2009 version. I put a new hard drive, with all of my information from my old drive installed on it, into the computer. but now have the blinking question mark folder. I see that it means that it isn't reading the new hard drive.
did i miss a step between transferring all of my information from my old hard drive to the new hard drive and installing the new hard drive into the computer. I believe that i installed properly. it was quite easy.
thanks for your help

It means there is no bootable system on the drive. If you still have access to the old drive, then I suggest you boot from it then clone it to the new internal drive. Use OPTION boot to boot from the Recovery HD on the old drive:
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     1. Select Disk Utility from the main menu then press the Continue
         button.
     2. Select the destination volume from the left side list.
     3. Click on the Restore tab in the DU main window.
     4. Select the destination volume from the left side list and drag it
         to the Destination entry field.
     5. Select the source volume from the left side list and drag it to
         the Source entry field.
     6. Double-check you got it right, then click on the Restore button.
Source means the external old drive. Destination means the new internal drive.

The RAW files I just downloaded on new MacBook Pro are designated as JPEG in the photo info box. Why??

The RAW files I just downloaded on new MacBook Pro are designated as JPEG in the photo info box. Why??

How did you download? Have you been using the Import panel?
How is the pop-up selector for the "Raw+Jpeg" set?
If you are importing raw+jpeg pairs, and you set this to (Use Jpeg as original), then you will see a little J on the thumbnail, otherwise a R.
Or did ou import with Jpeg only?

My MacBook Pro will not sync address book changes with my IPhone. Why? It used to.

My MacBook Pro will not sync address book changes with my IPhone. Why? It used to.

Then you may have to try manually resetting the syncservices folder by following Julian Write's post (from https://discussions.apple.com/message/9274781#9274781):
Ok, as you can't reset SyncServices in the "normal" way, you'll have to resort to the "other" way:
Although it's not advised to do so in normal circumstances, you'll need to manually delete the SyncServices folder.
Before doing so, you MUST make a backup of both your Contacts and Calendars:
In Address Book, choose *Export > Address Book Archive...* from the File menu.
In iCal, choose *Back up iCal...* from the File menu.
Then, make a backup of the SyncServices folder located at:
~/Library/Application Support/SyncServices
By backing everything up first, you don't risk losing anything.
Finally delete the aforementioned SyncServices folder and restart the Mac. This will force Mac OS X to recreate the SyncServices folder, and hopefully fix your problem.
I believe in Snow Leopard you can back up your calendar in File>Export>iCal Archive rather than File>Back up iCal as posted above.

No problems, go ahead, I'm doing it too, when the price for 16GB comes down a wee bit more.

Why does my 2012 macbook pro become slow sometimes?

I've purchased my 2012 4gb ram Macbook ram w/ 500 gb hard drive around September. It started off extremely fast the first 4 months (when I had mavericks), but there we're problems with the Video playback towards the last 4 months (It would Freeze and unfreeze & the the audio-video sync would be way off after 30 mins of netflix, which would cause the whole computer to slow down). So, I installed the Yosemite update, which made it even worse to the point where my macbook was unusable. With yosemite, I'd have an average of 500mb ram free memory available, sometimes even lower. Now, I did a manual restore to OS X 10.8.5 Mountain Lion, and I see the major difference in speed. I could use safari now & get an average of 1.47 gb of free ram available (with just the safari application open). Now, the video playback issue still occurs sometimes & having about 4 programs open does make the computer slower than usual, but not as often. I'm hoping this is just a ram issue, becuase I'm expecting on upgrading my ram to a 16gb ram or higher while still on Mountain Lion just to be able to run Logic Pro & Adobe Premiere in the near future. If its not a ram issue which is causing this problem on my macbook, I'd be ****** because I'd be spending almost $200 on a ram upgrade and it not resolving this issue would kill me. Could someone help? Ill even take a Diagnose test like Etrecheck if you need me to. Thanks.

Macbook pro runs slow, sometimes it is more than a minute to load a webpage and sometimes freezes.

My MacBook Pro is running very slowly, sometimes more than a minute to open a webpage or access a link on the page. Using Safari and sometimes it freezes and the force quit window doesn't appear using option-command-escape. Then only holding down the power button shuts down the computer. Thanks for any help.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

My macbook pro got hotter sometimes

I got a macbook pro mid 12 model. at the biggining the tempereture was stay cool and same all the time, but as time passes now-a-days my macbook got extreem hotter sometimes and get cold after few moments, it also happened when i used some specific software, so I stoped using those software. But the raising of tempereture is still happening. Need some sollution immidiately. Me using OS 10.9.2

Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

My 2006 Macbook Pro Only Starts sometimes

My 2006 Macbook pro starts sometimes and loads normal but sometimes it just loads to the Apple and the spinning gear. This just started happening recently. Any ideas? I have reset the Pram, and even installed lion again on the computer and it is still doing it.

Jakebeal,
have you tried going into Disk Utility and running its Verify Disk option, to make sure that everything’s OK with the folder structure on your MacBook Pro’s internal hard disk?

HT1338 my macbook pro will not boot up

my macbook pro seems to be dead! No bong at start up. I can hear the opitical drive start up briefly, then nothing: the only sign of life is the tiny white light on the open button at the front of the machine. tried safe boot, tried zapping PRAM, etc. etc. runing out of ideas. also has cd in drive that doesn't act like its wants to come out!

You can hold hte trackpad button down while booting, this should eject the stuck disk.
Far as your other hardware problems, see the first few steps here
Step by Step to fix your Mac
especially the SMC reset and checking the Magsafe links, let the machine power up overnight and see if it works.
Good luck.
