    JohnnyChin95,

     

    if you open up the Keyboard pane of System Preferences, and select the Keyboard tab, is the “Use all F1, F2, etc. keys as standard function keys” checkbox checked, or is it unchecked?

     

    If you try each of your function keys in turn, either F1, F2, &c. or Fn+F1, Fn+F2, &c. depending upon the state of the checkbox above, which function keys work properly, and which don’t work properly? For example, does Mission Control appear when F3 (or Fn+F3) is pressed? Does the Dashboard appear when F4 (or Fn+F4) is pressed? and so on.

    Hi Melophage,

    Thanks for reply,

    Ya I sure I uncheck the use f1 ~2 etc as standard, so if I press them without the fn, the special function printed on them(sound volume,play/pause,, screen brightness)will work.

    I can't remember when this problem show up, I used to adjust the brightn

    from the f1 & 2 or in side the display preferences,but now it disappears if I press the fn + f1 or 2 it will have an alert sound, which mean those key are working just software got problem, so any idea? I tried To reset the NVRAM so many time but problem just not gone.!!!!

    JohnnyChin95,

     

    have you tried resetting your MacBook Pro’s System Management Controller yet, to see if that makes a difference with its F1 and F2 keys’ functionality?

     

    Do you have reason to believe that your MacBook Pro is a counterfeit? (As you can see from these discussions, problems occur even on genuine Apple products.)

    Ya I reset it 3 - 4 time already but still the same, when I rreset SMC , I click shift control option and power in the same time but nothing Happen ( nothing show i. Been reset, but the mac not turn on during click those key,), I can't re install the os x, since I have no internet connection yet in my new house, does apple has email , so I can send to them? If I download 10.8.4/5, how big is the file?can my problem be solve after download it?

    JohnnyChin95,

     

    I don’t know which forms of support Apple offers in Malaysia, but in the US they only offer support by telephone — no support by e-mail. I haven’t downloaded Mountain Lion myself, but the Mavericks download was over 5 GB; my guess is that Mountain Lion would not be bigger than Mavericks. I don’t understand what you mean when you ask if your Mac is original — since I misunderstood the opposite of original as being “counterfeit”, what do you mean by a non-original Mac?

    Hi Melophage,

    Now I even found the auto graphics switching function in the power preference disappears!

     

    Beside reinstall os x, do I have any other way to solve my problem?(since my house temporary don't have internet)

     

    My mac actually still remain 2 month warranty but if I send to them I will wait very long to get my mac so I don't want.

     

    About the original, I mean my mac bought from online r send n assembly in shanghai, so I have a little worry does it is original by Apple's hand or is a counterfeit(does apple provide something to make sure it is a original product from them)?

    BTW, what is yr internet speed at that moment u download os x maverick n how long it take?

    Thanks!

    JohnnyChin95,

     

    reïnstalling OS X will probably be the only real solution. Will your house have Internet before your warranty expires? If not, then it would probably be better to send it to Apple, even though there would be a long wait to get it back; you’ve paid for the warranty in your purchase price, so why not make use of it? (You might also want to consider purchasing an AppleCare plan; you can do so any time before your original warranty expires.) Alternatively, do you know anyone with Internet access who would be willing to let you download OS X onto your MacBook Pro at their home?

     

    To my knowledge, all of the original MacBook Pros are manufactured in China; I don’t know where in China, though. If you received a box that has a sticker with your MacBook Pro’s serial number, Ethernet MAC address, Wi-Fi MAC address, &c., and all of that information matches what’s in your MacBook Pro, then that’s probably a good sign that you have an original Apple product.

     

    In my case, I have a relatively slow 3½ Mb/s downstream DSL connection, so it took about five hours for me to download Mavericks. If your Internet speed will be faster, then your download time should be proportionally shorter.

    Thanks Melophage, I guess send back to them is the way I can choose, but if I download the mac os x 10.8.4 or 5, does my problem can be solve? It will download some additional information some problem solving but not my problem type right?

     

    But I afraid even I download the os x 10.8.4 -5 for my mac and solved the problem software,there will be some hidden problem I don't know and not been solve so it good to send back

    JohnnyChin95,

     

    I’ve never run Mountain Lion on my MacBook Pro, so I don’t know if installing the 10.8.5 upgrade would fix your function key problem in 10.8.3 or not. If you fear that there could be a hidden problem, then your best option would be to make use of your warranty and send your MacBook Pro to Apple for them to make things right (and update to 10.8.5 when you get it back, if they haven’t done it for you).
