Installed new memory and Macbook Pro wont start.

I bought a total of 8GB from PNY for my mid 2009 MacBook Pro (2.8GHz Intel Core 2 Duo). I installed it and my macbook wont turn on. When I press the power button it just beeps. The LCD doesnt turn on. I reinstalled it a few times to make sure that it is sitting correctly with no luck. I reinstalled my old memory (2x2gb) and it works fine.
The new memory I bought is PNY 8GB (2x 4GB) Bual Channel DDR3 PC3-10666. The package says that it is compatiable with 1333MHz and 1066MHz. This is the listed memory on the PNY website for Mac laptops.
Am I using the worng type of memory? I'm pretty sure my MacBook Pro can take 8GB...right?
THANKS!

One beep indicates no RAM installed. See http://support.apple.com/kb/HT1547.
What happens when you reinstall the old original memory? Does the computer boot then?
You might want to read the information at macsales.com (OWC). Certain models had to be updated to take additional memory.

Installing new memory in MacBook Pro

I just installed a 2GB of memory in the slot where the 1GB was because it was not being recognized in the second slot.
When I first installed the 2GB in the top slot, which was the available slot, I turned the computer on and it didn't recognize the memory. I opened the back up again, and figured out that the memory was not pushed in all of the way, so I made sure that it was pushed in and when I turned the system on the little light was blinking, then I checked it again, and then the computer sounded that it was coming on but never came on, but the light was solid.
In order to make sure that there was nothing wrong with the memory, so I put it in the slot that the 1GB previously occupied, then put the 1GB in the available slot, which was the slot that was open from the beginning. At that point the system didn't boot up. But upon removing the 1GB from the slot and the 2GB being in the slot that the 1GB originally occupied, the system booted up fine.
The problem appears to be the slot.
Please advise.
thanks

I've encountered the same exact problem when trying to install an Axiom Memory Solutions 2GB PC2-5300 667MHz DDR2 SDRAM SODIMM [http://www.axiommemory.com/config/products/branded/MA347G/A-AX.aspx] for my 2.16GHz Intel Core Duo MacBook Pro. It is currently up and functioning with the 2GB memory stick in the inmost slot alone but does not allow for both 1GB and 2GB memory sticks to be installed at once in either order of configuration. I have yet to test to see if it will function with the 2GB memory stick in the outermost slot alone, in which case if it were to function in this configuration I would conclude the problem to be caused by the combination of the 1GB and 2GB memory sticks.
Every bit of information I had read prior to making the decision to purchase this 2GB memory stick assured me that my version of the MacBook Pro would function under a 2GB/1GB configuration, but my findings here prove otherwise.
In order to determine what step needs to be taken in order to obtain 3GB of overall RAM, I need the following to be ansered:
Does my version of the MacBook Pro in fact allow for a 2GB/1GB memory stick configuration? If this is the case, which 2GB memory stick must I obtain [in order to assure I'm purchasing the correct memory stick - this time - I require the utmost specificity]. If this is NOT the case, I must therefore purchase another 2GB memory stick to accompany the one I just purchased in order to obtain the maximum 3GB RAM for my version of the MacBook Pro [that only allows for 3GB maximum even if 4GB of RAM are intalled]. I would naturally purchase the exact same 2GB Axiom memory stick I previously purchased, but I need to know if this configuration will in fact allow my MacBook Pro to function.
I apologize for my lack of brevity, but I would prefer to be specific and not have to deal with this problem too much longer.
Thanks,
Christopher

Monitor not working after installing new memory in Mac Pro

I installed 4GB of new memory in my first generation Mac Pro following diagram. When I booted the monitor is black. The key board is working but not the monitor. I removed the new memory and tried again but same problem. Any suggestions on solving this problem would be greatly appreciated.

Well no one really buys from Apple and higher density goes into A1:2 then B1:2 and four DIMMs in those is best symmetrical configuration.
You say you tried xyz but not really very specific to me.
Some users doesn't tell much. However sometimes putting all the 512MB (not 500) on one Riser and the 4GB set on other has worked.
If it doesn't work with just the new RAM alone in A1:2 then it is bad or wrong and needs to go back.
And there have been 3-4 article changes on how to reset SMC. Yours has an SMC button. Leaving unplugged alone is a waste and almost useless. Hitting power button while unplugged was added in 2009.
And it could still be your GPU which is common - 7300 or X1900 or 8800GT... or...

Installed new screen on macbook pro 15" and now it boots fine but doesn't show the grey boot screen???

I recently installed a used but in good condition glossy display on my 15" macbook pro as mine the backlight was starting to have issues and there were some surface scratches on the screen. Anyway the screen works perfect except I don't get the grey boot screen when i start the machine up. You can tell the screen is on as you can see the backlight come on. But the screen doesn't actually show anything until it starts to go into OS X. not sure what the problem could be. I relize this is not a big issue but I am stumped on why it is doing this. Also maybe I am just crazy b/c I have dealt with the other screen for such a long time now but it doesn't seem like I am getting exactly the right colors and brighness on the new screen. I have calibrated it and all and like i said it might just be me. More concerned with the whole no boot screen issue. Anyone experience this before, and if so any solutions for me. Thanks.

It's hard to diagnose but you do have a problem. Take it to an Apple store or AASP and have them diagnose your damage. And, no AppleCare does not cover user accidents. Check with your homeowners insurance.

How to increase disk read and write speed after installing new SSD (2009 Macbook Pro)? Why not as fast as advertised?

Hi everyone,
I just installed a Crucial MX10512 GB SSD into my 2009 Macbook Pro. It's definitely much faster, but the read and write disk speed is around 200 Mb/s for both versus the 300-500 Mb/s that the SSD advertised. Any ideas as to why? And is there anything I can do to make it faster? Before I installed it, it was between 80-90 Mb/s.
Specs:
- currently have about 460 of 511 GB of storage available
- am using 2GB of memory
- running on 10.10.2 Yosemite
Thanks!

Drew, forgive me for being so computer-incompetent but how would I boot from another OS? And shouldn't I be checking the read speeds on my current OS (Yosemite) anyways because I want to know how the SSD is performing on the OS I use? And finally, what kind of resources would it be using that would be slowing down my SSD?
Sorry for all the questions - I'm not a Macbook wiz by any means!
You could make a clone of your internal OS onto an external disk. Hopefully you already have a backup of some form
A clone is a full copy, so you can boot from it. It makes a good backup as well as being useful to test things like this.
Carbon Copy Cloner will make one or you can use Disk Utility to 'restore' your OS from the internal disk to an external one.
Ideally the external disk is a fast disk with a fast 'interface' like Thunderbolt, Firewire 800 or USB3. USB2 can work, but it is slow & may effect the test.
You connect the clone, hold alt at startup & select the external disk in the 'boot manager'. When the Mac is finished booting run the speed tester.
Maybe this one…
https://itunes.apple.com/gb/app/blackmagic-disk-speed-test/id425264550
Test the internal & compare to the previous tests
A running OS will do the following on it's boot disk…
Write/ read cache files from running apps
Write/ read memory to disk if memory is running low
Index new files if content is changing or being updated
Copy files for backing up (Time Machine or any other scheduled tasks)
Networking can also trigger read/ write on the disk too.
You may not have much activity that effects a disk speed test, but you can't really be sure unless that disk is not being used for other tasks.
Disk testing is an art & science in itself, see this if you want to get an idea …
http://macperformanceguide.com/topics/topic-Storage.html
Simply knowing that it's about twice the speed would be enough to cheer me up

Installing New Hardrive into Macbook Pro 13" and can't boot

I have installed a new 500Gb 5400rpm drive into my macbook pro 13. Before I swapped the drives I used time machine to back-up onto my Lacie drive. Now the new drive is in. I turned on the computer, pressed the option button and nothing came up. I have now put my old HD into an enclosure and booted up from that drive. I copied my whole hd over to the new drive once it was formatted and tried to boot but this didn't work. I thought once I had the time machine back-up on a drive I would be able to press option when I turn on the computer and then that would workj. I don't have my OSX 10.6.8disk so am now just booting up off my old hd which is pointless. Can anyone help as I am losing my mind.

What happens when you install the original HDD in the MBP? If it does not boot , the connecting cable may be faulty.
Ciao.

Macbook pro wont start up and clicking sound

Hi everyone
My girlfriend spilled a coke on my computer couple days ago and my MBP shut down immediately. After all i took it to the apple store in Turkey and they said the problem is from the battery and they took it off and I started to use it on charge until i get a new battery. All day i used my macbook pro on charge without battery on it. Anyway I turned my computer off and next day press the power button to start it up and it didnt start up at all. Mag safe works OK. Charger light is green light and everytime i press the power button I hear a clicking sound and my built in cam light is lighting up. I couldnt figure it out what is wrong.. If you guys had any problem like this before or know the problem about it please share it with me.. I will be appreciated.. Thanks

Macbook Pro wont start up (Apple logo and spinning thing all I get)

When I turn on my macbook pro I get the “tone” the Apple logo and the spinning thing but then the spinning thing just freezes up and does nothing for ever. I let it just site like that for 30 minutes then it just goes to black. It is plugged in so power is not an issue.
I tried to boot up in safe mode and again I get the tone the logo then the bar to show the safe mode then the spinning thing then nothing. I did boot it up via firewire target mode and was able to see the hard drive and all my files on my imac so the hard drive works (I think).
I do have the original install disk and am willing to start the computer fresh but have no idea how.
So any suggestions???
I also tried to turn on and run the repair mode I think that’s where I held down a key the screen went black and some commands ran then I typed somting like flvr - fv
Thanks Brad

Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

HT1270 Macbook pro wont start after changing memory...

Hi! I have a 13 inch mac book pro late 2010 and i just intalled the new ram sticks but its not starting up properly. It never leaves the white page with the gray apple and turning wheel... I bought the DDR3 pc3-10666 instead of pc3-8500... Is that why?
Please help!

"... I bought the DDR3 pc3-10666 instead of pc3-8500... Is that why?"
Please help!
Most likely, yes. Macs are quite fussy about RAM specs. Return the new RAM and purchase the correct type/size.
Maximum Memory 8.0 GB
Memory Slots 2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM

Macbook pro wont start up and stuck on a restart screen, after mountain lion installtion failure

Instructing me to restart my computer, it has been stuck on this cycle for a few days now and i have no idea how to fix it.
Any help would be much appreciated

StephBeard,
if you still have your MacBook Pro’s original box, it can be found on one of the stickers on the box. If you don’t still have its box, it can be determined from your MacBook Pro’s serial number. If its serial number has eleven characters, write down the last three characters; if it has twelve characters, write down the last four. If you don’t have its box, please include in your reply those last three or four characters of its serial number.

Did you try resetting the SMC and PRAM?

Macbook Pro wont start, but pretenfs like it is going to and then turns off

So, I opened a game, the Mac crashed and, won't turn back on. Itll turn on for a few seconds and play that loud noise and appear like it's functioning properly and the little bar fills up a tiny bit but then it turns back off and repeats if I prompt it...any help?

Howdy xVaGuEx,
If your MacBook Pro is shutting down unexpectedly durning startup, I would suggest that you troubleshoot using the steps in this article -
OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support
Thanks for using Apple Support Communities.

Macbook pro wont start with 3 beeps

hi
Few months back I purchased a refurbished macbook pro (late 2012 model) with i7 processor and 8 GB ram. Now after 2 months I experienced problem with mac - it wont start with 3 beeps. I looked at different articles in net and found about no memory bank problem. I opened the back and changed slots and it seemed to fix the issue. However the issue was recurring few times and ram was changed. Again the issue seemed to have resurfaced. I tried with memtest in single user mode and RAM passes the tests.
What else could be the issue around the macbook pro. Do you suggest taking it to local Apple store to get it checked?
Thanks

Test each module installed alone while switching slots (power down before switching and remove battery.) Do both modules work alone in each slot? If they do, then it would appear the memory is good as are the slots. So, something else is at play and only an Apple Store has the equipment to go further - make a Genius Appointment and take it in for service.
