MacBook Pro (Retina, Mid 2012) - Boot Camp/Win 7 - Num Lock Problem

Hey,
I have a client who has a MacBook Pro (Retina, Mid 2012) who is experiencing a problem when booted into Windows 7 via Boot Camp in that he cannot type certain character like # (hash character by keystroke alt + 3) without Windows 7 error bleeping at him. He needs the # character as part of his password for logging into webmail.
The Boot Camp setup has the latest Boot Camp drivers installed (this was a fresh Boot Camp setup/install today) and every other part of the hardware works I suspect that this problem is not a key mapping problem but more something to do with Windows registering Num Lock as being active.
If the problem is that Num Lock is enabled then what is the keystroke to disable Num Lock? I thought it was fn + 6 but did this change since the Unibody MacBooks?
I understand that there are ways of resurrecting number pad fuctionality as decribed in the MacWorld article (see link below) but this is a Mac OS X System Preference and as such would not operate when booted into Windows via Boot Camp.

How do I toggle num lock in Windows 7 via Boot Camp 4.0 on a MacBook Pro (Late 2011)?

Is there a keyboard shortcut to enable num lock on the MacBook Pro 2011 (Late) in Windows 7 via Boot Camp 4.0? I have a mouse with a numpad mapping on the side of it. When I press the number keys, the cursor responds in the way one would expect it to with the num lock off (ie, 6 moves it right, 4 moves it left, etc); however, I need to use it to produce numbers.
I have read http://support.apple.com/kb/HT1220, which covers the previous MBP keyboard (on which the F6 key function was numlock), but I can't find any information regarding the possibility of doing this with the new MBP model keyboard (on which the F6 key function is increasing the keyboard backlight). Any thoughts? Suggestions?

I was looking for this answer and found it on another site. I realize this is an old thread, but just in case someone else stumbles here and needs to do it, here's how to turn numlock on or off in Windows, and to make it stick:
Run Registry Editor (RegEdit)
In Windows 8 or earlier you can press Command-R, then type regedit
In Win7 or earlier, you can also just click Start menu, and type regedit in the search field.
In the Registry Editor, navigate to HKEY_CURRENT_USER -> Control Panel -> Keyboard
Within the Keyboard folder, you should have an entry named InitialKeyboardIndicators. Set the "Data" value accordingly:
0 = Num Lock is turned OFF after login
1 = Disable Num Lock
2 = Numlock is turned ON after the login
I hope this helps.

New out of the box MacBook Pro with Caps Lock/Num Lock lit keys

I just set up my brand new MacBook Pro 15" laptop and, right out of the box, the Caps Lock and Num Lock keys were lit up. I didn't think anything of it, and transferred all my user files from my old PowerBook G4. Well, they 2 keys seem to be working in reverse. When Caps Lock is lit up green, all characters are in lower case. Same as Num Lock. Any advice? Do I have a lemon?
Thanks!

I've also had this problem twice over the past couple of weeks.
I have a theory that it has something to do with plugging in my USB mouse during the system boot. A reboot cured it both times though, and it's not gotten tot he point that it's annoying enough to investigate further.

MacBook Keyboard Caps Lock and Num Lock are working in reverse!!!

Ok, this sounds very strange...my keyboard on my MacBook only works when both the num lock and caps lock keys are depressed (so the green lights are illuminated). if the num lock is off then the keyboard does not work. if num lock is on and caps lock is off then the keys only type in ALL CAPS. if both num lock and caps lock are on (green lights) then the keyboard behaves as it should--except it's supposed to be that the num lock and caps lock keys should be off! I've checked system prefs for keyboard and mouse and for universal access, i've reset to defaults, i've restarted the machine...NOTHING works!
Has anyone ever seen this before? Any clue what to do?
thanks

Do computers have child diseases? My computer's immune system now seems to have taken care of the caps lock/num lock problem. I haven't had any inverted startups in weeks now. Very strange!
In my experience, the treatment is to ignore the fact caps lock/num lock is lit, and to restart the computer. If you need to log in to restart, do it as if startup was normal, since caps lock/num lock is not actually turned on.
And hope for the natural healing.
Does anyone have different experiences?

Blinking Caps Lock and Num Lock Keys Lit after spilling water Macbook Pro.

What does it mean when the caps lock and Num lock key blink, after spilling liquid on a Macbook Pro? Does this mean that liquid is still present? Also, the white light by the latch was blinking. What does this all mean?

Possible liquid damage.
Immediately disconnect all peripherals, power cord & remove the battery. Turn the computer over with the lid partly open and the hinge facing upward to let the liquid drain. Do not flop it over and lay it flat - you want to separate it from the moisture. Place paper or cloth towels under the machine to sop up the mess.
After the computer disgorges whatever you spilled on it, don't turn it on for 72 hours or longer. You want to computer to dry out completely before turning it on again.
Some users here swear by hairdryers. Blow drying the innards may bake whatever was in the liquid onto delicate computer components. Better to let the computer air dry.
Use plain tepid water to clean out the computer. If you spilled iced beverage more than likely this ice fried the hot motherboard.
Sugary, acidic or milky drinks will almost always cause problems later on as the residue starts slowly corroding the computer innards.
Swab down any sticky parts with distilled water or denatured alcohol.
If none of the above works, you will need to take the computer to a repair shop. Apple Care does not cover liquid or food damage. Believe me, they can tell. So the old "my computer stopped working" line is not going to work.

Macbook Num Lock Fault

When I first received my Macbook (quite an early model) I found when I switched it on, that the Caps Lock and Num Lock keys worked in the reverse sense. I took me a while to work out why I couldn't type in my password and why things were being typed in Capitals with the Caps Lock off. I quickly realised that I had to switch the Caps Lock and Num Lock on in order for the keyboard to behave normally. After a couple of restarts, the problem went away and I forgot all about it.
It has now returned and I find every 3rd restart (bearing in mind the Macbook usually goes quite a while without a restart) this fault reoccurs, but just with the Num Lock now. This renders a few of the keys unusuable for typing unless the number lock is switched on.
Has anyone come across this before ??

MacBook starts with caps lock and num lock ON

From time to time after upgrading to Leopard, my caps lock and num lock lamps are lit after startup. However, all other keys work normally, caps lock and num lock are not actually turned on. Is there a way to avoid this misbehaviour?

Num Lock Pad Doesn't Work With Fill In Forms

I have Adobe XI, running Windows * and IE 11. Num Lock key pad does not work with fill in forms. Can anyone help?

Sounds like you are using a third-party keyboard: the new Apple keyboards do not have a Num Lock key and the numeric keypad always functions as such.
If you're using a third-party keyboard, and if you installed vendor-provided software to customize the keyboard, check its preferences and also check the vendor's Web site to see if there is an updated version of the software for your keyboard.
I cannot reproduce the problem using the latest model of Apple Pro keyboard (the one that came with my computer, which is the same as your computer).
2. You might also want to state the specific keyboard and version of Excel you are using in case someone else has the same configuration and can try to reproduce the problem. I tried it with Excel from Office v.X.
3. You wrote: "* Deleted Excel Preferences"Both of them, yes?
- Home > Library > Preferences > com.microsoft.excel.plist (you may or may not have this one).
- Home > Library > Preferences > Microsoft > Microsoft Excel
Good luck!

Num Lock

Hello,
I just bought an iBook and I'm wondering if it is possible that if Num Lock is on, you still can use the other "free" keys, because I need this for a music-program (Sibelius)?
Marleen Palinckx
P.S.: I have searched for it, but I didn't find a "Delete"-key %-)

Folks
Can anyone tell me if they've come across a numeric keypad that works with the music software Sibelius, and with the macbook pro? I've tried some on which some, but not all, of the keys work.
Please help - I've tried calling Sibelius with no luck.
Also, what are some good numeric keypads that work with the mac and macbook pro? I'd be willing to go out and try some that are suggested to see if they are compatible with the software..
thanks
p.s it's too cumbersome and time consuming to have to hit function everytime to get the numbers on the keyboard to work, as many of you have found, I'm sure

Num-Lock Function

I have just purchased a brand new MacBook (basic but with 2 Gig processor and 2 Gig Memory). There is no num-lock function that I can find and the keys have no num-lock symbols on them. I've tried calling tech support 3 times and the guys can't seem to figure this one out. I've tried f6, fn+6, fn+f6 etc.
Does anyone know the answer to this mystery?

It's on page 22 here:

Num lock problem - Keeps flashing

I've got a num lock problem on my new Macbook at the moment. It keeps on flashing randomly, even when I don't use it. And when I press it when the led isn't on, it doesn't do anythin. Any ideas what might be wrong?

I don't think it is serious enough to return it. I have problems with my num lock and caps lock keys also, but I think it is a problem with the PMU firmware. Quite a few people are having an issue, so I don't think it is a hardware problem.
There are also people having other problems related to the PMU, such as the coloured lines at startup. I suspect we will see a firmware update at some point that can hopefully fix it.
My advice would be try resetting your PRAM with command-option-p-r at startup (until you hear the second chime). Or resetting the PMU by turning off the 'book. disconnecting power and taking battery out, then pressing power button for 5 seconds. Then turn it all back on again and it should be ok.
Stay away from 10.4.7 too, it's just trouble.

I fixed the LCD Brightness in my Samsung NP300 Laptop

tl;dr: acpi_backlight=vendor to kernel at boot (add in grub configuration) + modprobe -r samsung_laptop && systemctl restart gdm. (i discovered it with pf-kernel, need to try in stock kernel)
Well, i don't know if this is known, but i could not find it.
Maybe its a bug to be fixed that im not aware of.
Well, i had the common problem with the LCD brightness not responding. It used to decrease, but not increase. All of this running Gnome 3.
After days of fight what i did was download pf-kernel and configure it. I selected the "samsung_laptop" module as my common sense told me, and in case it was needed the Q10 Samsung or something like that module too.
I rebooted into the pf-kernel, with no luck, the same problem was still happening.
I decided to stop gdm and use startx to try some things.
First i modprobed the samsung_laptop module just in case, started X again, and it was the same.
And then i did modprobe -r samsung_laptop, restarted X... AND IT WORKS.
NOTE: The acpi_backlight=vendor is needed in the grub configuration to this to work.
Oddly, without the samsung_laptop module.
So i rebooted to try this again. Unloaded the module, did systemctl restart gdm, aand there it was working again.
So, it may be a problem with that module, or maybe its not needed after all, im not sure.
I'm kind of newbie in all of this, so if this is dumb or something im sorry but i think it may be helpful for somebody else in my situation.
By googling i only found scripts to make this work that i did not like.
Is neccesary that i place a bug report? Im not sure if that kernel module is made to fix this or if its for something else, so i dont know if the bug report makes sense.

More history on what does what.
At first, i could only decrease the brightness 1 step, from the max to one below.
Then i put acpi_backlight=vendor in grub, and i could decrease the brightness to some value (which is not the real minimum), but could not increase it more than 2 steps over that minimum once decreased (like locked in the 2 lower values).
To manually change the brightness i echoed values to /sys/class/backlight/intel_backlight/brightness. The other one did not work (samsung...), but it wasn't what i wanted.
After changing kernel, unloading the kernel module samsung_laptop and restarting x it works.
Not sure if the kernel has something to do.
