MacBook Pro 15" (Late 2008) not powering on!
MacBook Pro
Screen Size: 15"
Year: Late 2008
Specs: Unknown
I have aquired a MacBook pro from a friend and it does not turn on at all, I have tested the charger which works fine, changed the RAM which works fine, and even the battery says it has full charge.
I press the power buttong and there is absolutely no sign of power, neither the fans or the hard drive spin up, there is also no error beeps. The laptop is completely dead.
I have read online that it could be a possible graphics chip problem but from my experience with laptops with graphics chip problem (commonly nvidea) they turn on but there is nothing on screen or lines all across it.
I am asking whether or not to waste my time with this macbook, is it a logic board problem?
If it is a LATE 2008 then the graphics chip shouldn't be the problem as that was on the Late 2007 and Early 2008 models.
That doesn't mean the graphics chip hasn't failed and taken the rest of the logic board with it. Or simply the logic board has failed which seems to be fairly common for Mac notebooks.
In other words Yes it is Dead.

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.
Memory in the MacBook Air is not upgradable. If that's what you have, you should restore the previous system from a backup, or replace the machine. Ask if you need guidance.
The Etrecheck report clearly shows that SylvieRose has a Macbook Pro, not a Macbook Air and that there are only 2 GB RAM installed. The Etrecheck report can be very informative if one takes the time to examine it.

Macbook Pro 15" late 2008 random improper shutdowns on battery
Hi, my macbook pro 15" late 2008 model shuts down by itself when on battery. The problem started one day out of nowhere about 2 months ago. There seems to be no recurring pattern in the shutdowns as I can sometimes use the computer for one or two hours, sometimes only 5 minutes before it shuts down. The computer works perfectly when the charger is plugged in, and also when the battery is pulled out and only the charger is plugged in.
Here is what I've done so far:
Reset of the SMC
Reset of PRAM
Repair of hard disk and disk permissions with Disk Utility
Reinstallation of Snow Leopard 10.6.3 from disc and then install of all software updates
Reinstallation of all updates with the downloadable Combo Update
None of this fixed the problem.
I am a student in Glasgow, but normally live in Luxemburg. When I went back to Lux for the holidays I sent the mac for repair at Lineheart Luxemburg. The first time it was returned to me after a week. They hadn't detected the problem because they had only ran the tests with the charger pluggged in. I was quite annoyed as you might understand. All they told me was to buy an 85W charger for the mac as I only had a 60W one. This is my uncles old computer and I don't know why he had the wrong charger. I got the computer a year ago and it had worked flawlessly until now. The 85W charger didn't fix my problem.
I sent the mac back to Lineheart and they ran a second test for free. They found the problem and all they did was to repair the hard drive with Disk Utility and reinstall Snow Leopard 10.6.3. WHICH I HAD ALREADY DONE MYSELF. This time I was really annoyed. The problem basically occured again straight after I went to get the computer.
Now I am back in Glasgow and I have an appointment at the Genius Bar tomorrow. I hope they can be of a bit more help although the people at Lineheart are "Apple Mac Certified Technicians" too. I've already spent 140€ for nothing.
All I really want is to test the computer with another battery since the problem seems to really come from there. However none of the technicians did this and I don't have any friends with a similar model of Macbook.
The cycle count is at 263 and the status is "normal" for the battery.
There is a weird problem though, when I plugg in the charger the icon on the top right will first say "not charging" if I unplug the cable at this moment the computer dies. If I leave it in for about a minute it will start calculating the time until full charge. This takes MUCH LONGER than it used to and when it's done I get something silly like 20 hours or 6:30 hours until full charge. After 5-10 minutes it starts calculating again. After a long time I get something more sensible like 1:30 or 2 hours until full charge. Notice that during this entire time, the percentage of the charge will not have change by a single percent. It can sometimes take up to an hour until the battery actually starts charging.
I've read on different forums that this can be related to the logic board and then my Macbook will just have to become a stationary computer since I can't pay 1200€ to get the logic board replaced. I really hope I just need battery replacement.
Also, after I turn on the mac again after an improper shutdown my antivirus (avast!) will give me a message "An internal error has occured. You can find more information in the system logs. After filtering for shutdown this is what I found. (sorry for the screenshot, I couldn't find how to copy the log)
Sorry for this very long description but I wanted you to have all the information. I'm really getting desperate so any help is appreciated even if it's only on how to locate the problem I would be so gratefull. Thank you all.
Daniel LecoqYes, I boot up from the OS 10.6.3 installation disc and use Disc Utility to repair Disk and Permissions. I must tell you though, I've done the disc repair and permission repair quite a few times and it has never helped. Right now I've forgotten the OS disc in Luxemburg so I can only get it when I'm back in 3 weeks.
I ran Disc Utility today though and repaired permissions. The only one that wasn't fixed was an SUID-file.
I also checked the disc and it has some problems but I can't fix them until I get my OS disc or if I ask them to do it at the Genius Bar.
Yes, I have a Time Machine backup on an external usb HDD, last time I backed up was yesterday. -
MacBook Pro, 15" Late 2008, 10.6.7 Model 2,2 2.16 ghz Core 2 Duo
MacBook Pro, 15" Late 2008, 10.6.7 Model 2,2 2.16 ghz Core 2 Duo
This condition just sprang up. Machine not dropped, no new parts added, OS stable, no single or significant change to anything on the box. No new external hardware.
Did a restart and the following thing happens:
When power is initially put to the box, the screen lights up, and it displays a full screen, small checkerboard pattern. You can see the Apple icon underneath the checkerboard. The boot circle spins, and then the screen displays grey, and never makes it to blue.
So I tried to boot up in safe mode. The same thing happens at the start of the boot sequence, however, after entering the safe mode, the startup proceeds normally, boots to the harddrive, and when the box changes from grey screen to blue screen, the checkerboard on the screen goes away and I have a perfectly good display, with everything working normally (but in the safe mode).
I have tried the following:
Boot from Apple CD . . . Still get the checkerboard pattern through grey screen, then as the OS loads, the pattern gets worse, (goes from a full screen pattern, to something like a "two page pattern" and it never gets to blue screen, you can never see the OS desktop.
Won't boot from USB drive.
Won't boot from external Dvd drive (Reads the disk, but won't boot, just like the internal drive).
Already changed RAM, RAM slots, etc. Nothing plugged into any port. Everything disconnected.
Changed internal harddrives, same thing happens. Zapped the PRAM, Firmware is good, etc.
Since this event happens no matter the harddrive, and the box won't startup from the Apple CD, I'm guessing it's a piece of hardware that has gone bad.
The only thing I can think to do, is to unplug all the different ancillary items, (ethernet, USB, airport, CD, etc), one at a time, off of the motherboard, and keep trying to start up normally in an effort to isolate the hardware that is bad. In other words, if I unplug the airport card from the motherboard, and the machine starts normally, then I think I would have isolated the problem. IF it does not start normally, unplug the next sub system, and try it again.
YEs, I did run Techtool Pro, and etc., and all systems passed.
Any thoughts ?
Thanks So much,
erebus
Doesn't the safe mode disable all the hardware sub-systems? IS this why my machine starts in Safe, but won't boot normally ???Yes, I boot up from the OS 10.6.3 installation disc and use Disc Utility to repair Disk and Permissions.

What is the maximum hard drive size can I install into my MacBook Pro 15 "late 2008 ?
Hello community, I play with the thought in my MacBook Pro 15 "late 2008 equipped with an SSD hard drive. What is the maximum hard drive size can I install? Thank you in advance
Dirkmende1, greetings:

I don't recommend you to install a hard drive bigger than 2 TB if you are going to install Windows in Boot Camp or you may have problems
The largest 2.5" SATA HDDs of 9.5 mm thickness that I am aware of are 1 TB in capacity. There is a 12.5 mm thick HDD that will fit some MBPs. But I have not seen any of larger capacity.
Are there now 2 TB HDDs available for MBPs? If so, I am interested.
Ciao.
Both OWC and Crucial have SSDs of about 1 TB capacity.

MacBook Pro Unibody (late 2008) crash when using GeForce 9600M GT
Every time I do heavy 3D rendering or play 3D games (such World of Warcraft) with the NVIDIA GeForce 9600M GT, after few minutes my MacBook Pro (unibody, late 2008) freezes, black screen and audio looping, no actions possibile, only hard shutdown... No problems with the 9400M.
What should I do? Get a replacement?I've had mine for a little less than two months and I noticed the overheating shortly after I got it. I think it's mostly because the fans don't spin up soon enough because the SMC controller on mine does not work properly and even if you reset it, it reverts back to only spinning the fans after a cpu/gpu temps over 90 degrees Celsius (almost boiling point!).
Mine is currently in for service but I'm being told that they haven't been able to duplicate the issue so I don't understand what method of testing they are using. I hope they don't keep my computer in repair for a long time. I know that if I fire up the Black & White 2 Demo, Call of Duty 4, or Spore and play for about 10-20 minutes the computer crashes if the fans don't spin up... Apple released a firmware update for the SMC controller but it doesn't apply to my model which is a MacBookPro 5,1 , maybe Apple doesn't realize yet how widespread the fan problem even on the late 2008 model is but it needs to be resolved and a third party utility to control the fans should not be necessary on the finest laptops available on the market. I'm confident that they will come up with something...

Is it possible to upgrade a macbook pro 15 late 2008 memory upgrade to 8 go
Hi from Belgium,
Is it possible to upgrade a macbook pro 15 late 2008 memory from 4 to 8 go. And if yes would i have to replace both memory modules.
I'm also experiencing problems with the battery. Could you tell me if the new replacement batteries are based on the new techonology (long lasting) or if the replacement battery will be the same as the original one.
Thanks and have a good day.
FrancisHi CMCSK and thanks.
Maybe it's because of the SMC reset I've done.
My computer wasn't responding to the power button when pressed and used to shut down unexpectedly so I did the SMC reset as per the procedure hereafter.
http://support.apple.com/kb/HT3964?viewlocale=en_US
So according to you, the battery seems to work properly and doesn't need to be replaced.
Don't know if it's important but the figures I gave where the one with magsafe connected.
In fact for the time beeing I only use my computer with magsafe plugged.
I just unplugged the magpower and here are the new figures after 10 minutes.
Charge Information:
Charge Remaining (mAh): 3103
Fully Charged: No
Charging: No
Full Charge Capacity (mAh): 3491
Health Information:
Cycle Count: 245
Condition: Normal
Battery Installed: Yes
Amperage (mA): -1431
Voltage (mV): 11816
Are these figures still ok ? Thanks for your help and have a good day.

MacBook Pro 15" Late 2008 will not sleep on its own
My MacBook Pro will sleep just fine if I close the lid or select sleep from the Apple menu. It won't, however, ever fall asleep on its own. I've tried resetting the SMC to no avail. Any suggestions as to what I should look for?
Certain settings, e.g. printer sharing, can prevent timed sleep. If it's a brand new Mac and you migrated a fair amount of data from a previous computer, Spotlight may still be indexing. There are other possibilities as well. See this kbase article:

MacBook Pro A1286 Late 2008 WiFi Hardware Question
I'm working on a Late 2008 15" MacBook Pro model A1286. It had a plethora of issues, from broken trackpad, broken keyboard, broken display panel and a shot hard drive. It wasn't working when I got it in so I couldn't verify much. Upon fixing all of those issues and firing it up the WiFi is not working. The odd this is that the webcam uses the same cable, and that works just fine. Thinking it must be the card then, I ordered a replacement Airport card and put that in today, and the WiFi still doesn't work. What else could it be? Is it possible that only part of the cable would be bad for some reason? The owner says the wireless was working before the hard drive crash. The broken trackpad, keyboard and screen all happened prior, and they brought it in after the hard drive crashed, and had been using it like that for a while. Not sure what to do at this point... Any advice would be appreciated.
Thanks.owen-b,
Installing an SSD is very simple - just like installing a hard drive - all you need is a Phillips #00 screwdrive and a Torx T6 screwdriver. See the video here -> http://eshop.macsales.com/installvideos/macbookpro_15_unibody_hd/.
I prefer Crucial SSDs (probably because that's what I have!) and you can go to their website and look at the available drives. You can usually get a few bucks knowcked off if you purchase from Amazon.
Before you install the SSD, download Mavericks, quit before it tries to update and you'll have a file named "Install OS Mavericks.app". Get a 8GB+ USB thumb drive and use DiskMaker X to create a bootable installation drive. Hold down the option key with the USB thumb drive in place and elect to boot from it. Then use Disk Utility to format the SSD ("Mac OS Extended (Journaled)" with a single GUID partition. Quit Disk Utility and then install Mavericks.
That'll do it!

MacBook Pro 17" (Late 2007) not starting up after battery calibration (depleted)
Hi, I have spent most of today skimming through the advice given on these forums, but to no avail. I cannot power up my MBP. Since it is Sunday, I will give my best to find every piece of "soft" advice to try before giving up my daily workhorse to the official Apple Support.
Machine specs:
MacBook Pro 17" Hi-Res pre-unibody (2007)
Second battery - original bloated about a year ago (lasted 4 yrs! of continuous use)
SSD primary, HDD secondary drives
6GB om RAM
2.4GHz C2D
MacOS 10.6.8
Logic board replaced a few years back with faulty graphics (re-call).
This is what happened:
I decided to recalibrate my MBP (replaced, non-original NuPower) battery over the weekend.
I'm using my laptop at home and at the office, plugged in mostly. So it was advised to perform this procedure for the sake of a healthy battery.
Dreained it to the state of sleep nd then waited for the sleep light to go off.
A couple of hours passed after that when I returned to my desk and plugged in the adapter.
The LED went on GREEN (weird, I thought, but hoped it just did not pick up the completely drained battery right away).
Let it rest with that state for several hours. LED remained GREEN at all times.
Tha laptop sat still on the desk the whole time...
This is what I tried:
Unplugged, took battery out briefly, replugged - GREEN indicator.
Tried another adapter (60W instead of the original 85W), that adapter showed green as well.
Tried my AC adapter to charge another MacBook - charged fine, AMBER light.
- THIS MEANS the problem is with my MBP unit (incl battery).
Unplugged, took battery out, held the power button for 5secs (SMC reset), reassembled - no improvement
Tried all key-combos, held power button for 10secs
Took the battery out and tried to bott with plugged adapter, this normally works fine, but now nothing - no sound whatsoever
- THIS MEANS the issues is not with the battery, it is with the power management.
Sad thing is, that if it is the motherboard somehow that got damaged by itself, it means the end of this fine and capable machine. It is not worth the investment of a replacement motherboard and buying them from ebay is not a sustainable option
Tomorrow I will swap AC-adapters and batteries with an identical model of a friend. I will let you know.
I expect little you can help me with, but for future reference, the story might prove useful for similar cases. I was upset and surprised mainly because of the timing - not powering up after drained battery during calibration process.Dreained it to the state of sleep nd then waited for the sleep light to go off.
A couple of hours passed after that when I returned to my desk and plugged in the adapter.
Did you wait 5+ hours? Per article - http://support.apple.com/kb/PH7261 "After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer."

MacBook Pro Retina late 2013 not scanning for new WiFi networks
My late-2013 Macbook Pro w. retina screen is usually connected to my workplace wi-fi network.
Sometimes I need to disconnect from the usual network and connect to my Samsung S4's personal hotspot network.
I start the hotspot on the phone and I click on the wi-fi icon on the top bar.
Since a few weeks, the MacBook appears not to scan for new networks and does not show the phone's hotspot.
Earlier it used to display a "scanning for networks" message, and in a few seconds the phone hotspot's SSID appeared.
I am able to connect to the phone's hotspot using a workaround: from the icon, I click network preferences at the bottom of the list.
From the Network Preferences pane, in the middle, there is a droplist. I shows just the current network (the workplace network). I click the double arrow icon on the right and select "join other network". Then I cancel the popup window. The list now shows all networks around, including my phone's hotspot.
Is it a common/known issue? Will it be fixed? Thanks in advanceApparently, the 10.9.2 update fixed this.
the "Wi-Fi: Looking for Wi-Fi networks..." is back.
