Q: Fan noise & Battery

Hi guys....

 

Recently my macbook pro early 2008 (intel core 2 duo, 2gb RAM & 250gb Hard Disk) wouldn't switch on...

 

I saw a youtube video (http://www.youtube.com/watch?v=pPBN374PM7E) which told me to:

 

1) Get the battery out.

 

2) Hold the power button for 10secs.

 

3) Keep holding the power button and insert the power cable.

 

4) Do this for 10 secs.

 

5) Then release and count again till 10secs, but the power cable still in.

 

6) Insert the battery again after 10secs count down.

 

7) The click the bottom on the battery.

 

8) It switched on

 

Though, it made a loud noise of the fan and no battery was detected even though I have a battery plugged in.

 

Please can you help its urget!!!!

MacBook Pro, Mac OS X (10.7.5)

    Woah.......that video was made by a 10 year old.  Yeah, no on that.

     

     

    noisy fan reasons:

     

    A: you notice it more in a quiet room (the typical case) which is normal, all is AOK

     

    B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.

     

    C: fan rotor is going bad and making a whirring or buzz noise (rare).

     

    D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)

     

     

    A and D are normal

     

    B and C are not.

     

     

    If B and C continue for a long time (B is just a cleaning), they eventually cause the fan to either sieze and/or die.

     

     

    Make appt. with apple for diagnostics, however WHILE you have it apart, clean the fan good.  compressed air and Qtips.

     

    Its likely your fan rotor is dying.

    Try these directions:

    Note the ones for a MBP where the battery can be removed by the user.

    Thanks,

     

    But will this reduce the fan noise and eventhough my battery is plugged in and after I remove my power cord the computer is still on but the battery isn't detected in the system...

    It depends upon the reason why the fan is noisy.  It may if the system is not functioning correctly.

    and eventhough my battery is plugged in and after I remove my power cord the computer is still on but the battery isn't detected in the system...

    In what way?  Post from System Profiler the following:

    Hi thanks for replying once again.

     

    I tried the intructions for resetting the SMC, I tried this one:

     

    Resetting the System Management Controller (SMC)

    Resetting the SMC on Mac portables with a battery you can remove

    Note: Learn about removing the battery on MacBook and MacBook Pro.

     

    1. Shut down the computer.
    2. Disconnect the MagSafe power adapter from the computer, if it's connected.
    3. Remove the battery.
    4. Press and hold the power button for 5 seconds.
    5. Release the power button.
    6. Reconnect the battery and MagSafe power adapter.
    7. Press the power button to turn on the computer.

     

    But my mbp didn't turn on.

     

    Also, yesterday it did say "Condition: Replace now" in the battery section.

     

    I did have this problem before, but the youtue video helped me and sorted out the battery.

     

    In conclusion, my mac is not turning on. It did turn on when I followed the instructions from the youtube video...

     

    Its not a battery problem, because the lights on the battery show it is full.

    A healthy MBP should operate with the power adapter attached and the battery removed.  (though slower)

    That suggests that there is a problem.

    Not necessarily.  'Replace now' usually means what it says.  The battery lights show that it is full as it can get but it does not mean that there is enough amperage that will last for a meaningful period of time.  Check the capacity in System Profiler and compare it with mine.

     

    It seems like an appointment at an Apple genius bar would be a good option and I suspect a new battery may also be required.

     

    Ciao.

    Ok thanks for that...

     

    Lastly my problem is pretty similar to this http://www.youtube.com/watch?v=Laocw-AO7Fw but I have a macbook pro early 2008.

     

    Also I have a replacement charger instead of a charger from the apple its a charger for a 3rd party.

     

    Is dat good or not?

    Those instructions are for a Mac where one may not remove the battery.  The young lady said she had a Macbook Air.  Not applicable in your case

     

    Also I have a replacement charger instead of a charger from the apple its a charger for a 3rd party.

    More often than not, third party knock offs are bad.  That may very well be a contributing factor to your difficulties.

    Thank you so much for help!!!

     

    However, I bought this mbp privately (from a friend).

     

    Now will the apple retail store be able to help me repair this laptop or buying a new battery and a power adapter?

    The Apple store will assist you.You being a second owner will not be a deterrent for them.
