Late 2008 MacBook Pro Forgetting date and wifi settings

I have a 15" refurb MBP 5,1. It just started forgetting the time, date and my 802.11 settings including the WPA encryption key.
Previously I made a post in the Power Forum saying that when I plugged in the power adapter I got a message in the upper right saying "not charging" yet it really was. Now this.
I ran a repair permissions and that didn't seem to have an effect.

Happened to me the other day. First time date and wi-fi were lost. Second time only wi-fi. It has worked OK since then.
It could be the back-up battery or an intermittent problem with the Non-volatile RAM. Might be a case of back to Apple for a replacement!

  • Renewing a Late 2008 MacBook Pro: hard drive and battery substitution

    Hi all,
    I am an happy user of a late 2008 MacBook pro.
    However, with the passing of time, it became slow and the battery also deteriorate (it still quite OK, but it is not like at the beginning).
    But let's start from the beginning: the hard drive
    By googling for a while, I noticed that several people experienced very slow performance of their late 2008 MacBook Pro. That is also my case. Apparently, this is due to the hard disk which is dying, and then I considering to change it. However, I haven't found answers to these questions:
    - Is it possible to mirror all the containt of the current disk to the new one?
    - I only have the original installation disks of the first Leopard. I made all the updates through the network. Moreover, since it passed lot of time, I am afraid that some sector of the installation disks may be damaged. This means that I may fail in the installation of Mac Os X on the new hard drive. If I have to reinstall everything from scratch with the new hard drive and without installation disks, how should I do?
    - If I go a Mac Reseller shop, will do they perform this operation? And how much does it costs to make it? Or I may also go to some generic computer reparation guy?
    - Is it convenient to save all the data (movies, documents, pictures, emails, etc) somewhere (e.g. external HD) and then perform a completely new installation?
    Next, let's consider the battery.
    Here is a screenshot taken with iStat Pro:
    Do you think it is worth changing it? From System Profile I have those other info:
      Full charge capacity (mAh):          3386
           Current (mA):          846
           Voltage (mV):          12029
      Condition:          Replace soon
    What do you suggest to do then? How much does it cost a new battery? Actually, I think that also the processor performance deteriorate (it often becomes very hot, especially when watching Flash or Silverlight stuff), but, unfortunately I cannot change it.

    Hi!
    Thanks for all the answer. Please let me to resume this old and interesting discussion.
    After having evaluated several solutions (including NAS, different ways of backup, etc) I bought an external firewire HDD, since I believe it nicely fits my necessities. Next, after these holidays, I will finally replace my old HDD with a SSD one. I think 120 GB are ok. I just need the apps and small-sized documents (rather LaTeX, Matlab, word, pages or excel documents, etc. - no movies or mp3 (I have Spotify, for that) ). Large files (e.g. movies, pictures, etc) may end up in external firewire HDD.
    Now, let's consider the OS. I currently have 10.6.8 and I am very satisfied of that. I find it very stable, and all the apps I need are still well supported. On the other hand, given that there are like 5 years that I have the same installation, I may have a lot of obsolete files and setting that I can safely remove. This means that once I will have performed a backup of my documents, my email, my pictures etc. I can safely throw away all the rest. Hence, I may perform a brand-new installation of the OS. Although I am happy with 10.6.8, I was wondering if it is worth to upgrade it (I have a 2.53 Ghz Intel Core 2 Duo - 4 GB 1067 Mhz DDR3 RAM) to Lion, Mountain Lion or Mavricks. In that case, which would be the real benefits? And what about the cons?
    Finally consider that I only have the Leopard installation disks from 2008 (not even Snow Leopard) and I will bring my laptop to a techician to change the HDD (I know, it is simple but I don't have all the screws etc. and I will not buy them only for this purpose). Once he will have replaced the HDD, will he re-install the OS also? Or I have to reinstall the OS through my original DVD (5 years old, I don't even know if they still work) and upgrade to Snow Leopard again by myself? I would exclude the carbon copy solution since I may want to throw away a lot of garbage and perform a brand new instalation of the OS. How to proceed? Thanks again!

  • 2.8ghz late 2008 macbook pro with 8gb  and a happy ending but...

    This machine was bought on June 2009. A week after the mid 2009 were released. It was a refurbished unit which might explain it.
    Ok let's get started. I am using 1x4gb crucial module & 1x4gb owc module. Why mixing brands? Well by the time I decided to go from 4gb to 6gb, I found on Amazon the 4gb Crucial module for $190 while at Owc it was at $249. 6gb was a good combination for me and my needs. However, it didn't stop me from trying 8gb even knowing that my computer wasn't capable of using them. What was next? Yeah to buy another 4gb module This time I went for something cheaper (Owc's $179) since I wasn't sure if that was going to work.
    Ok enough of that and back to topic. 8gb works fine in the 32 and 64 bit kernels. I tested the 32 bit kernel for almost 12 hours with absolutely no problems. I was able to use 7.99gb flawlessly with the cpus fully stressed.
    The 64 bit kernel provided the same satisfactory results. The machine felt fast and reliable at all. The only thing I notice different was the temperature. While on the 32 bit kernel the cpu reached up to 85C, on the 64 bit it reached up to 92C
    I will keep testing the computer in the next days, but overall, I am pretty sure I will not have problems.

    Is this a math quiz? Do you have a technical question?

  • I have a late 2008 Macbook Pro last updated to Mavericks OS.  The screen died and it's not worth replacing.  How do I remove the hard drive and use a drive sled to access info I need?

    I have a late 2008 Macbook Pro last updated to the Mavericks OS.  The screen died and I took it into an Apple store and was told replacing the screen and the hardware to repair everything would cost almost as much as buying a new laptop or a cheaper model.  I was told that I can use a drive sled to access data I need on my hard drive. How do I remove my hard drive and use a drive sled to get to the information I need?  What makes matters more complicated is I need to update my iPhone and my iTunes/App store purchases.  How can I accomplish this?
    My wife has a late 2008 Macbook Pro as well, which I am assuming I need to run my hard drive.  Is there a way to just access just my hard drive without interfering with hers?
    I know this is lengthy.  Thanks to whoever looks at this and offers advice/instruction.

    the device you need is an External enclosure for a 2.5" (laptop form factor) SATA drive.
    A USB-interface enclosure will be slow, but is adequate for this task and for re-purposing as a backup drive later.  A firewire-interface drive would be faster, but is harder to find, more expensive, and faster than needed for this purpose.
    The drive will mount as an "extra" drive on your wife's Macbook, and you can drag and drop whatever you wish. You could create a separate Account for yourself on her computer, and use Migration Assistant or just copy your stuff over to the new account. Then it would not interfere with her files.

  • I have a late 2008 Macbook Pro, I am trying to run MW3 but it will not work without crashing a few minuets into the game. The general specs on my computer are a dual processor 2.53 ghz. 4 gb ram and a NVIDIA geforce 9400 (9600 is the alternate card)

    Things to note:
    I have been unable to update firmware on this computer for about a year now. Im not sure why.
    I am running a bootleg copy of Windows XP on this computer, I would not like to spend $149 to get Windows 7 if possible.
    any thoughts on the matter would be greatly appreciated, thank you.

    Why don't you take your 'old' MBP into your local Apple Store and have them check out everything that's wrong with it - and I mean everything? Then, when you get an estimate about how much it would cost to get the machine completely repaired, ask about the Apple flat-rate repair pricing?
    It's worth a shot - and with what you may save, you can put in the bank for a new MBP.

  • Hello.  I recently pieced together a late 2008 MacBook Pro 15".  Everything works fine except the battery constantly goes between "not charging" and "calculating" or, rarely "charging". It does charge after a long while and will report that it is charged.

    Hello.  I recently pieced together a late 2008 MacBook Pro 15".  Everything works fine except the battery constantly goes between "not charging" and "calculating" or, rarely "charging". It does charge after a long while and will report that it is charged.
    I have reset the NVRAM and the SMC a couple of time but that didn't work so I ran an Apple Hardware Test and while testing the logic board it gives the following error:
    4SNS/1/40000000 LB1T
    I've done some research and found this is a temperature sensor related to the battery, but cannot find where the sensor is located in the computer.  Would you know how I can find the sensor to test it?  Could my battery problem be related to something else?  Would a fresh install of Lion help?
    Thank you!
    Mike
    Two pieces of information that may or may not b helpful, the hard drive is from my early 2008 MBP and the only test disc I have access to is from an iMac.

    Why do you have LION installed on that older machine?
    So you say you built a macbook from a bucket of parts eh?   Kudos

    A 2008 Mac won't have originally shipped with Lion. You need to install 10.6.8 on the computer, log into the Mac App Store with the Apple ID you used to purchase Mountain Lion, click on the Purchases tab, and download it.

  • Just updated from a late 2008 Macbook Pro and I am getting a blink on my external screen

    I just upgraded from a late 2008 Macbook Pro with a  AMD Radeon HD 6770M 1024 MB graphics card and I am now getting a blink (black screen) every few seconds.
    Anyone know a fix.
    Thanks

    You could always give it a shot - the only problem that you might run into is that the the early 2011 might not boot when the hard drive is swapped from the 2008 hard drive. Some versions of OS X are simply not compatible between different models.
    But it's worth a try...

  • New macbook pro battery for late 2008 macbook pro dies fast.

    I have a late 2008 macbook pro 2.4 HGz Intet Core 2 Duo with 2 GB of ram. I've had it since 2009 and just got a new battery, as the old one finally gave up. That being said, the new battery dies quite fast and I'm not sure why. Any suggestions would be greatly appreciated! thank you

    Only problem is that maybe the battery you were sold was manufactured around the same time as the Mac. And LiPo batteries die because of old age as well as use. Take it out and carefully examine all markings, especially anything that can date when it was made, like copyrights or such.
    With that evidence you can go back and demand a refund.

  • How do I install Mavericks onto a new SSD HD in my late 2008 MacBook Pro?

    How do I install Mavericks onto a new SSD HD in my late 2008 Macbook Pro, and then I  hopefully can reinstall my data from my Time Machine backup?
    I presume the SSD will need some type of formatting, before I can install Mavericks from the internet? Then can I use my Time Machine backup to reinstall all my other software and settings?

    In order to load Mavericks the SSD will have to be formatted Mac OS Extended with GUID partition mapping

  • How to update graphics card drivers for late 2008 macbook pro with Nvidia 9600m GT?

    Can anybody help me update the drivers for my 9600m GT graphics card for my Late 2008 Macbook pro? I am running OS X Lion 10.7.5 with a Windows 7 partition. I have tried finding support on Nvidia's website, but at least for the 9600m GT, it isn't supported for my operating system. Would I have to update it from my Windows side? And if so, would the update apply to my OS X side as well? I have a little computer knowledge, but nothing indepth.

    Welcome to Apple Support Communities
    In OS X, Apple provides the GPU drivers and you cannot update them from NVIDIA. They are updated with each OS X update, so you are running the most recent drivers for your OS X version. OS X Mountain Lion and Mavericks have got more recent GPU drivers, but it's not worth upgrading unless you need newer drivers for an app (I highly doubt this).
    However, you can update the GPU drivers in Windows, and you should do it to get the best performance. You can download them from the NVIDIA site > http://www.nvidia.com/Download/index.aspx?lang=en-us Note that drivers are only applied in the operating system you are installing them, so they will not be installed in OS X

  • Can i connect thunderbolt duo hard drive to the mini display port of a late 2008 macbook pro which do not have thunderbolt port, but have mini display port.

    hi, i have a late 2008 15 inch macbook pro, which have a mini display port.
    I noticed that thunderbolt and mini display port looks a like. So, my question is :
    can i connect thunderbolt duo hard drive to the mini display port of a late 2008 macbook pro which do not have thunderbolt port, but have mini display port.
    thank you

    ken94538,
    no, you’d need a Thunderbolt-to-FireWire adapter or Thunderbolt-to-USB adapter to be able to access your Thunderbolt hard drive from your 2008 MacBook Pro.

  • How to transfer/migrate from Late 2008 MacBook Pro to MacBook Pro, with retina?

    Is there anyway of directly connecting a Late 2008 MacBook Pro to a MacBook Pro, with retina, in a Target Disk Mode way without having to wait for the magical adapter in July?
    Should I go to the Apple Store, buy a normal MacBook Pro, use it to do the transfer, and return it?
    Thanks to anyone for taking the time to answer.

    There is Setup Assistant when you first boot the new Mac, over wireless it's supposed to migrate for you, however I hear it can take hours and days to complete.
    http://manuals.info.apple.com/en_US/MacBook_Pro_Retina_QuickStart.pdf
    Another faster method would be to use the free/donations Carbon Copy Cloner the old Mac to a blank USB3, 2,1 drive, then hook it up to the new Mac and use Setup Assistant (or Migration Assistant) that way, it will think it's another Mac.
    You can also simply drag and drop files into a same named account on the new machine manually from the clone.
    It should take about a hour per 250GB to clone, about another hour for Setup Assistant.
    Over wireless it could take a eternity.
