Macbook Pro Early 2008 running slow, hot even with upgrades - what to do?

Hello!
Specs:
I have a Macbook Pro Early 2008 (Model A1260). I have upgraded both the RAM (from 2GB to 4GB DDR2 667) and the HDD (from the factory installed 200GB 5400 to a 750GB 5400).
Previous to this, I was running Leopard, and upgraded to Snow Leopard then Lion as my specs match the requirements. On the old/original HDD and RAM, All was good for about 3 months, and in the past month or two, I began to have performance issues, so after trying everything (including a clean wipe & reinstall using Lion Recovery) and doing a lot of reading in these forums and others, I decided/hoped the problem would be remedied with some upgrades (hence the new HDD & RAM upgrades).
This has helped to the point where I can now run safari without having to force reload or having the whole computer freeze (although that has now happened once), but I wasn't even able to load a youtube video.
CPU Usage:
I checked the activity monitor and I'm getting a pretty constant CPU usage of about 50% (even with no other apps running):
(The above is with just Safari, Dropbox, smcFanControl & Activity monitor)
My fans are engaged constantly (smcFanControl has my computer at 75º-80ºC at any given time that it's on).
The CPU usage & temps seems high - but I am not sure haven't found very good answers online.
Things I've Tried (Post RAM & HDD Upgrades):
I tried to perform a hardware test (holding D before the gray screen) - and both times I tried it, it did not work, as in Lion just loaded as normal.
Ran repair permissions - and some things were repaired.
Tried to run Verify Disk - no dice - the computer froze and I had to use the power button to shut it off & restart
Reset the SMC per apple support instructions - had no effect on the fans or heat (though I'm still not sure if this is a real problem or not!)
What I'm looking for :
Any ideas on what could be going on - is this just par for the course on older models running lion, or is there something more to be done?
I am really hoping to squeeze a few more years of service out of this machine! Thanks for any advice you can give me!

Incase you are using your MBP like a laptop (which it is NOT)...................
According to the user manual it states in part:
"Do not operate your MacBook Pro on a pillow or other soft material, as the material can block the airflow vents. Never place anything over the keyboard when operating your MacBook Pro. Never push objects into the ventilation openings."
MacBook Pro: Care, Use, and Safety Information
"Do not place your MacBook Pro on your lap or other body surface for extended periods of time. Prolonged body contact can cause discomfort and potentially a burn."

MacBook Pro (early 2008) not sleeping after 10.6 upgrade

I upgraded my early 2008 MacBook Pro to 10.6 on Tuesday in what appeared to be a seamless upgrade. Everything works perfectly afterwards except that it now no longer sleeps when left. It will sleep when put to sleep or when the lid is closed but no longer from the Energy Saver settings. I've done a PRAM restart, tried it on power, on battery, with and without drives and networks connected but it stubbornly refuses to sleep. It ALWAYS slept reliably under 10.5 and nothing has been changed apart from the OS upgrade. I can see no untoward processes running in Activity Monitor and am at a complete loss to explain this very frustrating behavior. I would appreciate any help as this has completely ruined an otherwise faultless upgrade!

Hi-
I had the same problem. Open console in the utilities folder, and look to see if there is an epson file that it is trying to launch. It should look something like this:
9/9/09 5:13:47 AM com.apple.launchd.peruser.501216 (com.epson.epw.agent93833) Exited with exit code: 1
9/9/09 5:13:47 AM com.apple.launchd.peruser.501216 (com.epson.epw.agent) Throttling respawn: Will start in 10 seconds
9/9/09 5:13:57 AM com.apple.launchd.peruser.501216 (com.epson.epw.agent93834) posix_spawn("/Library/Printers/EPSON/InkjetPrinter/EPW/IJEPWAgent.app/Contents/ MacOS/IJEPWAgent", ...): No such file or directory
Snow Leopard changes the epson drivers in /library/printers/epson/inkjetprinter/... to /library/printers/epson/inkjetprinter2/..., and deletes the files that the computer is looking for. The easiest way to fix this is to go to epson's web site and find the driver's download for the picturemate dash (PM260). Under there you will find a universal updater for 10.6-10.6.x. Run this installer (file name is epson13044.dmg) and then restart. Check the console to see if it is trying to launch the file, but you should be good (if this was the source of your problem.)
Hope this helps, and let me know if you have any more questions.

My macbook pro early 2008 running 10.8.2 frozen in system preferences under desktop/screensaver after a hard reboot and force quit still frozen with spinning wheel - help

After selecting System Preferences and the selecting Desktop/Screensaver the laptop stays in a frozen state. It continually shows a spinning wheel and even after a Force Quit and also Holding Down the Power Button to shut laptop down anytime I go into Desktop/Screensaver it still shows a Spinning Wheel. What can I do to try to resolve this issue????? I'm thinking I will have to Re-Install Mountain Lion on my MBP. I just purchased this as a used system and also my 1st Mac coputer. It is most probably something I have done BUT now need to resolve this irritating issue since I can't change my desktop picture nor change my screensaver. Who knows what else may be going on.....
Please, someone give some constructive guidance...

Quit System Preferences if it's running. In the Finder, hold down the option key and select Go ▹ Library from the menu bar. From the Library folder, delete the following item, if it exists:
Caches/com.apple.systempreferences
and move the following item to the Desktop:
Preferences/com.apple.desktop.plist
Launch System Preferences and test. If you still have the issue, put the item on the Desktop back where it came from and post again. Otherwise, delete the item.

Questions regarding hard disk replacement in MacBook Pro Early 2008 Edition

Hello -
You folks probably get this a lot but I have a MacBook Pro Early 2008 edition and would like to upgrade the base 200 GB 5400 RPM drive to a Seagate Momentus 7200.4 drive. I have a few questions regarding this, and would appreciate any feedback.
1) Does anybody know if installing a new hard drive in a MacBook Pro would cause the warranty to be invalidated? I don't believe a hard drive is considered a user replaceable part, at least from what I read, and I would like to know if replacing it myself would void AppleCare.
2) Does anybody have any experience with the Segate Montentus 7200.4? I'm interested in how reliable the drive is and how much heat it generates. I've quickly discovered that I can use my MacBook Pro as an oven in tight spots and would like to prevent it from cooking its own internals.
3 random) Does anybody know at what temperature the system actually overheats? I'm seeing 171 F and this is with smcFanControl turned up to the Higher RPM mode. I'm a little nervous when I'm running WoW and the system is averaging above 170 with smcFanControl totally cranked up to 6000 rpm.
Thanks everyone!

Thanks for that. I've had mixed results with both Seagate and WD, but less issues historically with WD. My experience with IBM/Hitachi makes is nearly impossible to recommend their products, so based on what I'm seeing the Western Digital Scorpio Black looks like the best bet. Do you happen to know if Apple will do hardware installations outside of warranty repair scenario's? Ripping open my only notebook to perform "involved" hardware maintenance is not something I'd prefer to do, even with my technical background.

I have an early 2008 macbook pro that is running slow after upgrading to lion. Is there anything I can do? this is what I have,Processor 2.4 GHz Intel Core 2 Duo, Memory 2 GB 667 MHz DDR2 SDRAM.

First, back up all data immediately, as your boot drive may be failing.
Launch the usual set of applications you use when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. What approximate values are shown for Reads in/sec and Writes out/sec?
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

MacBook Pro Early 2008 Severe Overheating

I have an early 2008 (non-unibody) 2.5 ghz 15" MacBook Pro with some severe overheating issues. I'm trying to eliminate what ISN'T the problem and at the point where I think it may be a malfunctioning heatsink. I'd like to get a more expert opinion though.
The first symptom was hotter than usual operating temp, which could be felt near the top of the keyboard. It became so hot that it was no longer comfortable to place the machine on your lap. The fans were operating way more often and harder than usual. Eventually, one of the fans got worn out and started making a heck of a racket. I've read a lot about this and I know it's not uncommon.
I thought it was some software that may be causing the problem, so I took a day and opened up the machine, blew out any dust, disassembled and lubricated the right (problematic fan), formatted the drive, and reinstalled OS X. I really thought this would help, but when reinstalling OS X, the machine kept overheating to the point where it would shut down. I felt relieved when I was able to get it completely installed.
Now with no other software installed and just Safari running, it sits at an operating temp of about 90C (according to SMCFan Control)! The right fan is screaming again. I can get it down to 75C by forcing the fan speed up to 6000, but that's with no program running. Heat is particularly severe at the bottom of the screen at the fan exhaust (slightly more on right).
Unfortunately, I can't run a hardware test because the SuperDrive is dead (3rd one on this machine).
Any help on diagnosis is very welcome.

From Apple support article TS1258:
MacBook Pro (Early 2008): Dark bands showing intermittently on built-in display.
If the issue persists when running Mac OS X v10.5.3 or later, a quick reset of the display panel will reset the LED backlights. The quickest way to reset the display is to use the following key combination:
Press Control - Shift - Eject.
After the display goes to sleep, wake it by pressing any key on the keyboard.
I get this all the time on my 2008 MBP and the above usually works.

My Macbook Pro (early 2008) won't boot, then booted, now won't boot again.

Hey all,
Summary:
My GF's Macbook Pro (Early 2008, non-unibody I believe) "died" earlier this year without notice or a cause for why, then it worked months later, then it didn't again.
Symptoms:
It stopped booting, with the only signs of life are:
The annoying boot sound that you hear right-away, like a winding sound. "Weeeeah woooo"
A fan turns on immediately after the sound.
The front light (on the open button) is solid.
The battery will light up and show how much juice is left.
The only thing to do from here is to hold down the power for 10 seconds.
Don't worry, my story gets more interesting...
Now, I had another computer and my GF didn't need her macbook seriously for a while, so I didn't research the problem or how to fix it, until last week. Perusing the various help forums and communities, I came across the reset SMC suggestion, so I decided to try a few things on Apple's SMC reset page.
I tried a couple things, including taking the battery out, and LOW AND BEHOLD: IT CAME ON, like nothing happened! The screen was fine, the performance was fine, it updated (to the new Safari and iTunes, as an example) fine, and it restarted fine multiple times. One of the main reasons I wanted to get it working was to save some family pictures we had saved, so I started uploading the images to an image cloud site. I'm sending them at full-res so it takes a while and I go to sleep around 2 am so I'm not too late into the office in the morn. When I wake up, I go to check the image upload progress and the laptop is Off. I figure it just went into standby after finishing, so I hit the power button...
And it doesn't boot again. It's back to the same issue as before. I try doing what I did last time, then resetting the SMC, but nothing has worked this time.
Any ideas? It's out of warranty of course, which is why I'm here.
Thanks in advance!

Since no one else is answering, I’ll jump in.
Your story is interesting indeed. I’m not sure I can help you fix the Mac but it sounds like there is a reasonable chance of recovering the data.
I assume it came with installation disks. Will it boot from them? If so run Disk Utility from there and try to repair the system disk.
For the hardware problems on your Mac it is time to take it to Genius Bar at an Apple store for a free diagnosis and estimate of repairs.
Genius reservation http://www.apple.com/retail/geniusbar/ .
It could be your disk failing but it sounds more like flakey electronics in the system. Let’s assume is is the system board until a Genius tells you otherwise. If so, you can simply put the working system disk in an external enclosure, mount that on your other Mac and copy the data. Here is a source for the inexpensive hardware you would need:
Toolkit: http://eshop.macsales.com/item/OWC/TOOLKITMHD/
SATA enclosure: http://eshop.macsales.com/item/OWC/ES2.5BPU2W/
There are multiple directions to go from here. Let me know what happens when you try theses first options.

Black Screen on MacBook Pro Early 2008

Hey guys,
i have a problem. My MacBook Pro Early 2008 doesnt boot anymore. If i press the power button the screen remains black and the hdd spins a few seconds and you can hear the superdrive make a short noise. But nothing more happens.
I know from the nVidia 8600m GT issue and i even have the modelnumber A1260 but the apple reseller told me that if there comes no start sound , it is not that problem. My question is: is it possible that the (probably) defect 8600m gt chip on my logicboard has caused a defect of the whole logicboard ? I heard from a guy whos board was repaired for free but its PowerManagment Unit on the logicboard was defect but the Technical guy told him , that it was caused by the nvdia chip and so it was repaired for free. How can i find out if my chip was the reason for the defect ?
Iam not a native speaker and i hope you can understand what iam trying to say iam happy for every correction and help.
greets
max

"How can i find out if my chip was the reason for the defect ?"
By having it examined by a certified Apple technician. If necessary, show the tech the KB Article: http://support.apple.com/kb/TS2377 MacBook Pro: Distorted video or no video issues
"apple reseller told me that if there comes *no start sound* , it is not that problem."
You do not have a start sound?
Have you tried starting up from your install DVD?
If you have AppleCare, strongly suggest that you contact them first.

I need to install on macbook pro (early 2008) one hard disk 1 TB. Is it possible? What kind of HD is it better?

I need to replace the HD of my macbook pro (early 2008) with another one with 1 TB storage capability. Is it possible? What kind of HD is it better?
Thanks

Take a look at what is offered by Mac specialists, such as OWC http://www.macsales.com and see what drives they handle. Their drives are all guaranteed to be compatible with Macs. And they have on-line videos that show how to do the installation.
Even if there are problems getting them to deliver where you live, you can get ideas of what works well with your system.

Won't power up -- 17" MacBook Pro Early 2008 2.5GHz MB166LL/A MacBookPro4,1 Apple Model #A1261

I have a 17" MacBook Pro Early 2008 2.5GHz MB166LL/A MacBookPro4,1 Apple Model #A1261. I bought this used last year, and installed one of OWC's 1TB 2.5" Hybrid HD/SSD drives in it last January. No problems whatsoever until the past 2 weeks, when I started having intermittent black screens (NOT display sleep) -- sometimes the black screen would disappear by itself, sometimes I had to (Power button) shut down, and when I restarted, everything was OK. Until yesterday.
First let me note that, because I usually use the MacBook Pro in the same area in my house, I usually leave it plugged into the MagSafe power cube, and often just close the lid and put it to sleep, instead of going through start-up every time I need to access it. BTW, battery (NuPower) shows 5 solid green dots and does not seem to be a problem
Night before last, I shut down the MB Pro, and closed the lid. Yesterday, I opened up the MB Pro, and hit the power button. All I got was a brief, non-pulsing white light on the display-locking/“sleep light” button, and a sort of graunchy whisper from what sounded to me like the optical drive, NO screen activity whatsoever, and the “sleep light” went out within 3 or 4 seconds. Could hear NO HD spin-up sounds.
Tried everything I knew (not much), including disconnecting the MagSafe charger and removing the battery completely, letting it sit a few minutes, replacing battery and charger, and powering up. Same nothing, just another very brief whisper of activity from the optical drive. Being something of an “I’ll try anything, no matter how dumb it seems” idiot, I put a known, working, burned data CD-R in the optical drive. Removed the charger and battery again, waited, put everything back in. Tried to power up. Still nothing, same brief whisper from the optical drive, but the MB Pro would STILL not start up, the CD-R wouldn’t spin up OR eject, and I heard nothing from the hard drive, even with my ear ON the metal right over the drive.
My next “don’t-really-want-to-do-it” step is to remove the 1TB drive, replace it with the original 250GB drive, see if that works, and, as I have a “Newer Technology” Voyager S3 bare drive (works with both 2.5” and 3.5”) USB dock connected to my main Mac (a mid-2011 iMac, 2.7GHz Core i5, OS X 10.9.3), I’ll try using that to check the hybrid drive.
I’ve been a Mac-only user since 1989, and somehow this doesn’t seem like a drive problem. I’ve tried every OS X keyboard shortcut on the “OS X keyboard shortcuts” page, and the “sleep light” always comes on for a couple seconds, then goes out, the screen never even shows a flicker of life, and the HD NEVER spins up.
Can the forum please clue me in with any tricks I haven’t tried yet?
Thanks
Bart Brown

Thanks for the quick response. However, none of the following have worked:
Have you tried SMC and PRAM resets?
As usual, "sleep" light briefly illuminated -- 2-4 seconds -- then went out. No startup, no chime(s), no screen, no keyboard illumination, no HD spin-up.
Also try an Apple Hardware Test.
Same as above. Nada. "Mac NoteBook and Desktop computers shipping with OS X 10.7 or later have a partition on the hard drive or flash storage that contains AHT" -- since I can't get the drive to spin up, I can't access that partition... or anything else.
You may need the #2 installation disk.
Well, there I have TWO problems:
One is that I bought this MBPro on eBay, and received no disks -- it came with OS X 10.9.x installed (and is now at OS X 10.9.3). Is there any way to get “retail” install disks that will work with this MacBook Pro?
Second is that there's a data CD in the optical drive. Because the MBPro won't boot, I can't get the data CD out even if I had the 2nd Install DVD. Any way I can get this data CD out -- hatpin, barbecue skewer, fencing foil, sledgehammer?
I talked with OWC, from whom I bought the hybrid Seagate HDD/SSD 1TB drive last November. We tried a few ideas he had — mostly the same as those suggested by “Oglethorpe” (no relation to “Ogie” Oglethorpe in “Slapshot,” I hope!) — none of which worked, as I’ve already indicated above.
My last-ditch effort-of-desperation is to remove the hybrid Seagate HDD/SSD 1TB drive, and put in the original 250GB drive (never throw away a good drive!), and see if the MBPro returns from the dead. I will also put the hybrid Seagate HDD/SSD 1TB bare drive into my Newer Technologies Voyager S3 bare-drive dock, which takes 2.5” and 3.5” drives, and see if there’s a problem with the hybrid Seagate HDD/SSD 1TB drive. While no longer under warranty with OWC/MacSales, it IS still under a 2-year warranty with Seagate.
Any other suggestions gladly entertained.
Thanks again.

Hi, I have an Early 2008 Macbook Pro and I used it this morning but two hours later, I found it off. When I push the power button, the white light briefly comes on but it doesn't sound like it's starting up. When I hold the power button down, the white light comes on solid for about 5 seconds, then flashes rapidly. During this time I can hear the DVD drive and other components kick on, but once the rapid flashing stops, all power is lost again
The problem: Mac will not turn on.
1. If I hit the power button it is trying to start working (white light is blinking, HDD rotating, CD noise and so on), but gets shutdown as soon as I release my finger from the power button.
2. The maximum "Working" time is about 5 secs. During this time fans are working, white light is lighting, HDD working, CD does its usual noise. At the last two seconds white light starts flickering.
3. If I remove all memory slots it is working as usual!!!, I mean working without pressing a powerbutton constantly... and asking for a memory of course.
How it happened: well, it is usual thing then you are in hurry. Accidentally I hit restart. I didnt want mac to load again, so I did a force shutdown (5 secs an a power button). Thats it.
What I tried to do: I did all those "shaman" hotkeys to restart SMC. I spent a day!!! by driving around my city and asking Apple providers to fix it with no luck.
What I am planing to do:
1. I have an Apple service center here in the Tallinn who are ready to do some diagnostics. The only thing is - I dont trust them my HDD. So I am gonna clone my hard drive data somethere before they get my mac in their hands.
2. As soon as diagnistics is done I will get a price offer to fix it. It definitely wont be a cheap, since my mac is year and two months old (funny, two months and you are screwed).
3. If it will be too expencive I gonna do DIY repair.
What I would like to say to the Apple: please investigate that problem. The motherboard is definitely working. I can not fix it myself with no necessary equipments here, so I have to do expensive motherboard logic purchase.
Aleks

since my mac is year and two months old (funny, two months and you are screwed).
Not if you had of purchased Apple Care. You would have been covered for 3 years.
What I would like to say to the Apple:
This is not the place as Apple does not come to these forums.
These are user-to-user forums where everyday folk post "technical" questions and offer answers to each other voluntarily. No one here works for Apple nor does Apple get involved in responding. Not even sure if they "lurk."

MacBook Pro (Late) 2008 running 10.8.4 Have a Black Screen cannot get out of sleep mode/will reboot/will sound off at restart.

MacBook Pro (Late) 2008 running 10.8.4
I was using my computer every morning as I do everyday with no issues. I had left home for most of the day. Closed lid and while I was gone for a couple of hours. I returned home, opened my MacBook and nothing but a black screen. I've tried many things all evening try and fix this problem out of "safety sleep mode, and other similiar tricks that other people had tried.
I still have a Black Screen and cannot get my macbook out of what seems to be the sleep mode.
I've done a master reset and after I restart, I do get the power up chime but still a black screen. I don't know what else to do. Please help. Should I bring computer to a local repair shop or is there something I can do to fix myself. I just don't know where to start.
Thank you.

Can you put a 1.5V SODIMM in macbook pro early 2008?

I was looking at the memory in my MacBook Pro (early 2008 - model MacBookPro4,1 series) and noticed that it's using a 1.5V 200-pin SODIMM but all the other SODIMM modules I've been looking at are 1.8V - any idea what would be the affect of using this 1.5V memory? Wouldn't there be a lot of system crashes if the memory were not compatible with the MacBook? If it matters it's a 2.4GHz Core 2 Duo running Lion 10.7.2
The memory part is a DMS Certified HYS64T512022EDL-3S-A 4GB 2Rx8 PC2-5300S-555-12-DO in case that helps.
Thanks...
-Bob

Abosultely positive - the model is a A1260, Part number MB133LL/A, MacBookPro4,1 according to System Information app - and these all point to MacBook Pro Early 2008 according to my research. I believe the newer MacBook's use 204-pin SODIMM not 200-pin SODIMM so that's the big tipoff to me.
I'm not much of a hardware expert but I do remember e=i*r so with the same current less voltage means less resistance and that means less heat generated to me. But like I said, I'm not a hardware engineer or expert.
Thanks again for the help...

Macbook pro early 2008 freezing only in OSX

Hi everyone,
My macbook pro early 2008 (last model before the unibodies), 2.4 Ghz, 4Gb, 8600GT freezes only in OSX.
I'm typing this message right now on the same computer, but on windows 7, bootcamp.
Whenever I boot up OSX the system freezes every few seconds for a minute, only to resume work a few seconds before freezing again.
I know it isn´t a harware fault, since I can still boot up in windows 7 and use the snow leopard CD, which brings me to the next point.
I´ve allready used the disk verifty (which pointed out errors) and the disk repair (which was succesful).
I´ve also verified permissions and repaired them successfully.
What I´ve also done is turn off the sudden motion sensor.
The last thing I´ve tried is running the software update, making sure the system is up to date.
The battery is a few months old (new one) and the power cable works as well.
All of which did not work. I really don´t want to do a complete disk wipe since the backing up is horrendous.
I´ve read a lot on the subject, but since I don´t use an external monitor or have the unibody one the supposed solutions do not apply to me.
Thanks for you help!

You have already tried the "standard" troubleshooting solutions. Most times an issue cannot be diagnosed unless the computer is physically examined by a repair tech.
How large is your hard drive and how much hard drive space do you have left? Not enough space can cause the issues you are having as well as a failing hard drive -
Common symptoms of a dying hard drive are the following:

System freezes and hangs.
If you have Apple Care, give them a call. Otherwise, take the computer to an Apple store or an AASP for a proper diagnoses.
