April 2006 MacBook Pro freezing up

Hi everyone!
The MacBook Pro I bought in April 2006 (has CoreDuo 1.83 ghz) has started freezing up, particularly during on-line game play (I'm a geek, okay, and I play WOW.) :0) I increased my memory from 512 mb to 1.5 gigs back in January, but did not use Apple memory. Also, despite numerous fan control apps, my MacBook Pro is still really hot to the touch after extended use. Are these two issues related, and if so, what can be done?
Thanks for any ideas anyone has!
MacBook Pro Mac OS X (10.4.9)
MacBook Pro Mac OS X (10.3.9)

The 'freezing up' could be heat related, memory related or storage capacity related (at a guess)
Heat: Run the Hardware Tests from Install DVD1 (hold d at start) and see if it reports any MTR (fan motor) or SNS (heat sensor) errors ?
Memory: This is also tested when you run the above but a better check is <a href=http://www.memtestosx.org/">memtest (small charge for the download)
Storage: How much free space left on the drive? When did you last run the 'chron' jobs to clear caches etc?

April 2006 macbook pro core2duo wakes up from sleep with in sleeve

The title pretty much sums it up, The past couple of days I've gotten home from work and my macbook pro will have the screen on, and running. I have no open programs, I have reset the pram and the cmu to no avail. This really concerns me, I'm wondering if anyone has any insight. I made an appointment at the genius bar tomorrow, but I know that the problem won't be able to replicate when I get there. Just seeing if anyone else has encountered this.
Thanks

Welcome to Apple Discussions!
There are a couple of things to check.
First, be sure the Mac is truly asleep before you put it in the sleeve.
Second, be sure the latch is working properly. If the lid pops open because the latch pops loose, the Mac could wake up.
Otherwise, good luck at the Genius bar.

Mid 2006 Macbook Pro won't boot (from HD or optical)

My mid 2006 Macbook Pro will not boot from the hard disk, or from the internal DVD. I am currently running the latest version of Lion (10.7).
I tried searching the forums and found a similar issue here:
https://discussions.apple.com/thread/1687899?start=0&tstart=0
But that was with a Mac Mini. And it doesn't look like the OP issue was ever resolved. I am having the exact same problem.
When attempting a normal boot from the internal HD of the Macbook Pro. It will make the happy chime of a successful POST. It will display the Apple logo. And that's as far as she gets.
No spinning wheel, no error image, no nothing. Eventually the system will start spinning up the fans as if it were under load (this was after about a half hour of just letting it sit there).
Doing a verbose boot, it never went past this:
com.apple.driver.Apple.IntelCPUPowerManagement
Photo of verbose boot:
Here's what I've tried.
1. Bought a brand new battery (as the current one was at death's door)
2. Zapped PRAM (Apple + Option + P + R)
3. Reset SMC according to these directions: http://support.apple.com/kb/HT3964?viewlocale=en_US
4. Attempted to boot to my original Tiger (10.4) install DVD, only to stop at this point during a verbose boot (Apple V):
Extension "com.apple.driver.AppleACPIPlatform" has immediate dependencies on both com.apple.kernel and com.apple.kpi components; use only one style

5. I am able to put her in Target Disk Mode (hold T at boot). Then with a firewire cable I can connect it to my wife's Macbook 13" and I am able to run disk utility on it! Disk Utility did find and repair errors, however, it still refuses to boot.
6. I attempted to boot from my wife's Macbook 13" in Target Disk Mode. I put her machine in Target disk mode. Connected the firewire cable. Powered on my 15" MBP while holding the option key. Then I selected her drive as the boot disk... however it still refuses to boot even from a known working HD.
7. Finally, I swapped around RAM DIMMs with no change in behavior.
Help! I know she's an older gal (Laptop is 6 years old now) but I'm not exactly flush with cash and would rather not give up on her just yet.

My Mac started freezing (colored pinwheel) every time I tried using any application (i.e. Safari, iPhoto). After restarting for the 2nd time, it would no longer boot - makes start up sound but gets stuck on gray screen w/ apple icon. I tried resetting PRAM also - did nothing. I decided to reinstall OS; problem now is my HD is nowhere to be found! I am a tech dummy so this is way beyond my comprehension...I'm not seeing my HD from the Disk Utility either???
Side question...I backed up my files (mostly pics JPEG and videos) on DVD (had to compress to save). Why can't I open files on PC?

My macbook pro freezes and then displays a blue screen with black stripes... do you know what's wrong with it?

My macbook pro freezes and then displays a blue screen with black stripes... do you know what's wrong with it?
I have a two and half year mac book pro... I've had some issues with the screen looking scrambled when I quit certain applications, but now it's turned into something worse. I'll be working on my computer and the thing will freeze. When I force restart, the first screen, the apple logo, will be a blue tint and won't boot up normally. Then I try safe mood and it will then boot just fine. But there are blue stripes on my screen. The screen alternates from a blue tint to normal and if the computer freezes again the screen will become completely blue with black stripes. I haven't tried reinstalling my software because I don't have the startup discs that came with my computer. If I was sure that would fix it I would purchase them, but if it's a hardware issue I'm afraid that I'm screwed. I've been able to successfully get the blue off my screen by putting it to sleep and then waking it up, but that's not working well anymore either.
Does anyone else have experience with this? Is it the firmware or what? I have a MacBook Pro from early 2011 and I'm running Mac OS X 10.6.8.
Please help... Thanks!

I just experienced this exact same issue with my early 2011 15" macbook pro. Since like a month after purchasing it I had issues with the screen randomly going dark on me. I sent it in for repair inder waranty they replaced the gpu and logic board but I continued to have the same issues with the screen randomly going black sometimes I would need to reboot it in order to get the screen to go back on but it happened so infrequently and I used the computer for school so disnt find the time to resend it in to apple. Just last night the screen started to display the blue screen with black verticle lines on it. I called apple and explained to them the issues that had been ongoing since I purchased the laptop but they said because I was now outside of warantee that any repairs at thia point wouldn't be covered. Fml so glad I spent 2200 on this future proof macbook pro what a joke my sister purchased a toshiba laptop for 300 4 years ago and it still running like a champ. I loved my macbook but at the price I paid I expect it to last longer than 2 years before leaving me high and dry. *** apple??

Macbook pro freezes for no reason even after installing 10.8 on a brand new hard drive

Macbook pro freezes for no reason even after installing 10.8 on a brand new hard drive.
Tried to reset pram, smc, nvram.
Tried installing new RAM.
Tried installing new hard drive.
You should know that my internal drive is installed in a cheap external case and plugged in a USB 2.0 port because i am waiting for a new hard drive cable.all
Yep all good things happened to me...i don't know if all these problems are linked, ahh and also my trackpad is behaving very erraticaly sometimes, it's like it is possessed by a ghost. My computer is not under warranty anymore so i'd like to avoid a trip to the Apple store but i'm close to doing just that.
Any help appreciated...

It's diagnostic software. It's supposed to help you find problems. I don't think anyone is making any software yet that fixes hardware problems.
That said, the two comments:

.....also my trackpad is behaving very erraticaly sometimes, it's like it is possessed by a ghost....
would lead me to think it's the logic board. On older MacBook Pro's both the USB I/O ports and the keyboard/trackpad are fed out of an integrated USB controller integrated into the South Bridge I/O controller. On newer models, the USB ports come out of an integrated North/South bridge controller and the keyboard/trackpad are handled by an SMC controller, which itself interfaces with the I/O controller. All of these items are on the logic board, and they're all unrepairable.
...unless of course the "internal drive [that] is installed in a cheap external case" is itself causing the problems. Another thing to try might be a different USB port, if you haven't done so already.
I didn't know the price for Scannerz went up. I could have sworn I only paid 30-some bucks for it. Maybe it was on sale at the time. I don't remember.
In any case, good luck.

I replaced my hard drive on my late 2006 Macbook Pro. I tried to do a reinstall of Tiger 10.4.5 from my start up disk. I get an error that states "can't install on this computer." HELP

I replaced my hard drive on my late 2006 Macbook Pro. I used the disk utility and erased the drive and formatted it to OSX Journaled . When I tried to install the OS from the start up disks I got the error "Can't install on this computer. I have verified the drive.
I have used Super Duper to copy my old drive to my new drive. But I wanted to do a fresh install. How do I go about this?

Did you do the Super Duper clone before you tried to reinstall the OS? If so, the original install disc is likely earlier than 10.4.11, and that may be why you are getting the message.
When trying to reinstall the OS, did you select the "Archive and Install" option? If not, you might try that. Here's a link that might help:

Need help migrating 2006 Macbook Pro to 2012 Macbook Pro

Hi -- The screen on my 2006 Macbook Pro (running 10.9.2) completely stopped working last weekend. It doesn't light up at all. I've tried everything under the sun to get it functioning again but I believe it is just totally dead. I tried plugging an external monitor, mouse and keyboard into it and cannot get it to show up on the screen, which is driving me crazy! The monitor works just fine with my 2011 Mac Mini (running 10.6.8). I have been able to access the hard drive via target disk mode using the Mini and copy all of the files onto an external drive, which brings me relief that not everything is lost. I tried to boot the drive in startup manager on the Mini to do a Time Machine backup and the Mini didn't even enter startup manager. It just completely ignored the fact that I was pressing the Alt key at startup and proceeded to login normally! I have tried it several times and no dice. I'm feeling frustrated! Argh! Am I doing something wrong? Am I crazy? Anyways...
I bought a refurbished 2012 Macbook Pro and I would like to transfer all of my applications from the 2006 using migration assistant but I've read that some of them might not transfer correctly, such as Adobe CS6 suite and Final Cut Pro X. Unfortunately, I don't have the disks for these applications. Am I totally out of luck or is there a way to do this that I haven't seen yet? I'm willing to try anything at this point. Another question I have is will a Thunderbolt to Firewire adapter work with my 2006 MacBook Pro?
If you have any insights on how to transfer all of my stuff over, I would very much appreciate it. Thank you!

Yep, it was in target disk mode. I don't have a thunderbolt-firewire adapter, but I'm going to get one and try that -- I honestly wasn't sure if it would even work with my older Mac. I ran migration assistant with the Macbook Pro 2006 in target disk mode connected to the 2012 with an ethernet cable and it didn't find the drive.
So there's really no way for me to gather all of the various folders for FCP and put them on the new Mac?

My macbook pro freezes in safari or google chrome or just shuts down all together

My MacBook Pro freezes constantly when using Safari or Google Chrome. I have to reset to continue with anything.
It happens more often when using Java to play games and sometimes just closes the browser.

I don't know if we are experiencing the same problem, but this is what I did and it seemed to work for me so far.
Before anything I had to hard restart my laptop. hold power button until off then turn back on.
In Finder click on Go, then click Go to Folder. in the dialogue box type
/var/db/crls
In that folder there are two files that you need to move to the trash
crlcache.db
ocspcache.db
You will need to type in your password to move these to the trash.
Restart your computer and then Empty the Trash. It is very important that you empty the trash afterwards. I forgot to do this the first time and I had to restart the whole process. It has been a few days and I have been without any problems.
I am not claiming this process to be my own, I found it on another discussion thread and it worked for me. I don't have a link to it because I had to use someone else's computer and had no luck trying to find it again. This is the procedure I followed, I do remember it well and I wrote down the steps because I had to do it twice and got tired of combing through all of the websites I have searched looking for a fix to my problem. Hopefully this helps, and try it at your own risk of course.
Let me know if you try it and it works or not, good luck.

Need to format the drive on a 2006 MacBook Pro 10.6.8. Command R does not get it to recovery mode. I need to format, reload OS10 and partition the drive.

I tried command R to get into recovery mode. My goal is to format the MBP drive, partition the drive and load Windows through Boot Camp. Disk Utility will not allow access to reformat the drive. Is there another access method to format the drive?

jjoside,
Snow Leopard (Mac OS X 10.6.8) does not come with Recovery mode; you’d need Lion (Mac OS X 10.7) or newer for that. If you’d like to reformat your internal disk and reïnstall Snow Leopard on it, you’ll need to boot from the white retail Snow Leopard DVD which was originally used to install Snow Leopard on your MacBook Pro. [Your 2006 MacBook Pro came from the factory with Tiger (Mac OS X 10.4.something) installed.] If you no longer have your white Snow Leopard DVD, you can purchase a replacement Snow Leopard DVD from Apple.

Have a 2006 MacBook Pro with wireless mouse and Keyboard. Some of keys (caps lock, tab) on KB do not work any longer. I attempted to replace wireless KB with wired KB, but could not find one that was compatible with Snowleopard (10.6.8) OS. Would like to replace KB with either another wireless KB or wired KB.
However, in view of the scarcity of the above items, it appears I might serve myself better by fixing my current KB. Any suggestions?
Thanks!
