Problem with my MacBook 7,1 after Memory Upgrade

Hello, I have a MacBook (7,1 late 2010 model with the Intel process) and I just tried upgrading the original 2 GB ram (2 - 1 GB chips) with 2 - 2 GB chips (Total of 4 GB of Ram). It boots up fine, allows me to log in then when I went to the Apple Icon to get the system specs, the mouse icon starts to spin. It did this for 5 mins. before I had to do a hard restart. I took them out and place them back in three time, each time it boots, allows me to log in but then if I click on an app (FireFox, e-mail, etc.) the mouse icon just spins and spins.
I then put the original memory chips back in and the computer is working fine. I assume that with the computer booting up, that the ram chips are not bad. I'm running OS Lion. Any help would be great, thanks.
Got the ram from OWC, they both are Apple/Micron PC850 DDR# 1066MHz SO-DIMM.

it could be possible that one of your new RAM module could be defective.
have you tried to boot with one of the 2GB and one of your 1GB installed? Try that with each of the 2GB then if the problem you're having occurs when you have one of the 2GB installed then you know you have a defective module.

I have problems with my Mac Book Pro after I upgraded it

I upgraded my Mac Book Pro from MAC OS X 10.9 to Yosemite version a week ago, and now it doesn´t start

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Problem with turning macbook pro on after being put to sleep

My macbook pro is acting strange, if i put it to sleep after 50% battery and turn it on again i get a grey screen, then it turns off. if i use the power button again it boots up and tell me that the time and date is not accurate then it turns off again.

Try a SMC reset
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its 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.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Has anyone else had problems with the iPhone 4 overheating after an upgrade to iOS7?

My iPhone has been running hot sinced I upgraded to iOS7. Today, it rattled through more than 50% of its power while I was sending a text message, became so hot that I couldn't hold it, switched to temperature protection mode and then shut down completely. It is now blank.

Same for me! my iphone 4s gets extremely hot whit IOS 7.0.2.

Problems with result area in workbooks after upgrade to BW 3.5

Hi,
we are experiencing some problems with our <b>workbooks</b> after the upgrade to BW 3.5. When refreshing all queries in a workbook (that was there before 3.5) without selecting a specific query we get the message <b>'Result area</b> cannot be found, specify a new one'. After selecting, the message appears again in an infinite loop.
Has anybody had similar problems and has found a solution for this?
Thanks,
EMS

Hi,
I am having that message, always if I delete a Sheet which contains an embeded query.
Even the sheet is deleted, the SAPBEX has information of all the embeded queries, and tries to find the Result area to put the data.
To find out if this is your case as well,
select an empty cell in a Sheet and continue like that, until all the embeded queries are been displayed.
Regards
Vasso

After having yet another problem with my MacBook Pro and having to wipe the drive, I am now unable to sync my iPhones etc without erasing all the music on them. Is there a way around this? I have no other library!

After having yet another problem with my MacBook Pro and having to wipe the drive, I am now unable to sync my iPhones etc without erasing all the music on them. Is there a way around this? I have no other library!
iTunes is a mess! It couldn't find it's own libraries and I was forced to create a new one. Now I don't know where my music is or if any's missing.

How crap is that?
It's not crap at all.
It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
There has to be a solution.
Why not simply make a playlist with the songs you want on the iPhone?
and maintain a current backup of your computer.

I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies. After starting it in recovery mode, it will not allow me to download OS X Mavericks- it says the disk is locked. Any ideas? I do not have a back-up and do not want to erase everything before I have explored my options. Help?

try forcing internet recover, hold 3 keys - command, option, r - you should see a spinning globe
most people will tell you to do both pram and smc resets (google) and if you still have issues, either clean install (easy) or troubleshoot (hard)

Is there a phone number to call Adobe. I go around an endless loop pressing their contact info tabs? Maybe someone at this sight can help. I am new to digital photo - I have been a B&W film photographer for many years. I have a problem with a Macbook Air. It was working fine - I was using LR and a message came on the screen that said something like the memory was dangerously low. I stopped and tried to delete LR files. I couldn't do it. I closed the program and tried reopening and got the message that there is not enough memory available to open LR. I contacted Apple. They spent a half hour on the phone with me and eventually told me they didn't know how to help. The tech said that LR had gobbled up all the memory and said I should contact Adobe and ask where and how my photo files are stored and to delete them. I have several back-ups. Thanks - Arthur

This sort of error message only comes up for Lightroom when your hard disk is full. Indeed this has nothing to do with internal memory as that will be intelligently be dealt with. If you have a mac Book Air that is not so surprising as the cheapest versions come with very small hard disks and if you shoot raw with any recent camera, you'll fill up your hard disk very quickly and you can probably only store a few months of pictures if you are a typical photographer. So the bottom line is that you need to create some room on your hard disk. You should move some of your originals to an external hard disk. You can also delete some of your backup copies of your catalog file that Lightroom automatically generates every few days and that quickly gobble up hard disk space. So first figure out how full your hard disk is. To see that, go to the apple menu, hit -> About this Mac -> More info->Storage. You should see your internal hard disk on top and you'll find that it is almost entirely full with photos. Now find your Lightroom catalog file using Finder. It is usually in a folder in the Pictures folder in your home directory. You should see a Lightroom 5 Catalog.lrcat file, a previews file and a folder called backups. Inside the backups folder, you'll find a lot of subfolders. They have names that show the dates the backups were created. If you have backups of your entire hard disk, you can delete these backups when they are older than a few months. I usually only keep the last 4 around. Just drag the folders into the trash can on the dock on the bottom of your screen and empty the trash. This will probably free up enough space that Lightroom will already run again. Now start thinking about where you will want to store older images. If you have a good USB3 or Thunderbolt hard disk that is probably the best option. There is a video here by Adobe that has some instructions on how to do this: Is Your Hard Drive Full? Here’s How to Move Images to Another Drive in Lightroom. « Julieanne Kost's Blog If that doesn't work because you don't have enough hard drive space to run Lightroom yet, here is another set of instructions to move your files using the finder to the other hard disk: How do I move only my photos to another hard drive, leaving the catalog where it is? - The Lightroom Queen. If you follow that, as soon as you confirm all your images are on the new hard disk, you can delete them from your internal one. She is not so clear about that part but if you don't delete the originals that you moved off you don't free up space. You should move the folder structure over to the new hard disk and then reconnect the folders in Lightroom. That should make it refind all your images.
That said, if you are uncomfortable with the computer in itself, your best bet is to find a local photography club. There is invariably a Lightroom savvy person in there that could help you move your files. That might be your best bet if you are uncomfortable moving these yourself. A general mac savvy person like you would find at an Apple store or so generally will not be able to help you with this except when they are photographers themselves and know Lightroom. You might get lucky with that.

Hello i have some problems with my macbook pro

I finally found out my problem with my macbook and 32inch lcd

So I dont know if you have read but i have been having a little problem with my macbook and my 32inch lcd. The problem that I have been having is when it is hooked up threw the dvi to vga going into my t.v is that when i were to close the macbook it would goto sleep. Well i have done many things to prevent this from happening and nothing worked. I have the new apple wireless keyboard and mouse. After a few post I was told to do many things like click the mouse which I had already tried about 1.1 million times. Well after I was sick of it all I just got so mad at the whole situation. I tried one last time clicking and holding the mouse button down it stayed on. I thought I was dreaming this so I then tried it again and it worked. I was having the problem of closing the macbook then waking it back upp with the mouse and the my screen which would be the 32inch lcd would just flicker a few times then say no imput. I no longer have this problem

problem solved
