Illuminated macbook keyboard- not all keys illuminated.

hello
im hoping maybe some one can help me figure something out.
i have a 2.4 Ghz aluminium macbook i got apple refurbished about a year ago.
i noticed this morning that only a few of the keys are illuminating fully in the center of the keyboard
while the rest are very dim to the point of being useless.
i have not had this problem before and it was working fine on when i last had them illuminated on thursday, today is monday.
anyone know what could have caused this and if there is a solution?
any help would be great. its not a massive issue everything else is working fine.
its just a little annoying.

Hi Pete,
I just noticed 2 other things in regards to your post.
1) Sorry, I meant to type your dumb sisters drunken friends ... and not her boyfriend.
2) I also noticed you have a unibody construction. Im afraid you might have to replace the top case.
Newer "chicklet" constructed key sets are normally attached directly to the top case, but you might want to confirm that with Apple. The Mac Book air keyboard is attached to the top case and is only replaceable when purchasing the entire top case. If its any consolation, it will more than likely repair the other issues you mentioned in your last post in regards to the clicking and trackpad problems as well.

Not all keys responding - can it be remapped ?

not all my Macbook pro keys are responding and some seem remapped. How can I remap the keyboard to original settings. I can type using the keyboard viewer and the mouse - a real drag- any ideas?

Go into your System Preferences, Universal Access, and choose Mouse & Trackpad.
Chances are "Mouse Keys" is turned On. Turn it off, and you'll be set.
Ever since Apple removed the "numlock" on certain MacBook models, there's apparently some shortcut you can inadvertently hit that turns this on, and when you do, your i key becomes a mouse click, and the characers around the i actually operate the mouse (this is what Mouse Keys does).
It's frustrating and I only just now figured it out myself.

DROID Physical Keyboard Problem - All keys don't work!

Like many others, I switched to VZW in December from an iPhone so using a virtual keyboard was familiar to me - however, I had tried using the physical keyboard but noticed that not all the keys work (i.e. the space bar, backspace (delete)). I simply wrote it up as quirk and thought it was something that would be corrected in a future update (2.0 -> 2.1). Now 2.2 is about to be pushed any day now and rather that be optimistic that it's a firmware issue, has anyone else had this problem?
I've done a factory reset on the device so it currently has nothing but the stock applications that it came with; so it can't be a market app that's causing an issue.

Hi. I am sorry you are having issues with your keyboard and I will be happy to help you from here. I haven't had issues with my keyboard at all. How long has this been going on? It sounds like a hardware issue that we can help you with by going into the local store.
Please let me know if you have any other questions.
Thanks!

Home sharing iMac and MacBook Pro: not all songs are playable

Hello
I set up Home Sharing between my iMac and MacBook Pro so that I could stream the music that's on the iMac to the MacBook Pro. On the MBP there are no songs, all of them are in Apple Lossless format on my iMac. I first tried to use "‘share my library on my local network" but because I wanted the play count to go up as well I chose for "Home Sharing". Setting up was simple. After all preferences were adjusted, I opened iTunes on the MBP and it immediately found the shared iMac library. There's now only one problem: not all songs are playable. Some don't even start. How is this possible and what do I need to do to resolve this?
FYI: the iMac is connected via ethernet to my cable modem which sends a wireless Wi-Fi signal to the MBP. Signal quality is excellent.
Also, is it possible that playcount is only available with Home Sharing and not with "share my library on my local network"?
Thanks!

It very well could be the antivirus app, most are intrusive and debilitate rather than enhance performance and should be removed using the developers instructions. You haven't really told us anything useful such as any settting you may have changed. However if you began working backwards resetting any changes and uninstalling the apps added since the performance issue started then you probably will find your issue.

HT4236 when i sync photo's between my i pad & my macbook pro not all of them appear on the Ipad? any ideas

Hi there, when i sync between my Ipad 2 & Mac book pro, not all the photos make it.
Anyone have any ideas, its quite frustrating
All boxes are ticked for full transfer,
best wishes

Try deleting the photo cache from your computer and then re-try the photo sync and see if they all then copy over - the location of the cache, and how to delete it, is on this page.

2011 Macbook Pro boots, all keys seem to function, blank screen

Yesterday at around 5pm EST my Macbook Pro (2011 model with the AMD Radeon HD 6750M) froze while browsing the internet (specifically XDA-Developers). This wasn't a normal " freeze" were it starts responding after a few minutes. Nothing would function, the caps lock key wouldn't light up, etc. Naturally, I held down the power button and shut my laptop down assuming it would work upon rebooting. Unfortunately when it started booting it just got stuck on the gray screen sans Apple logo. Now this is where things got weirder:
I tried turning it on again, but nothing happened. I didn't get any chime or anything. I began looking up troubleshooting guidelines on the internet and reset PRAM, NVRAM, SEC etc. Occasionally I would get it to boot and I tried booting into my Windows 7 partition, but it just stalled on the Windows 7 starting logo. After this I had continued problems where sometimes the screen would display vertical lines ontop of the gray screen, horizontal lines covering the bottom half of the screen while constantly making the booting noise but not actually changing, and just not turning on at all.
Finally I let it sit for awhile and turned it on. I got the chime and decided to just let it be, thinking it might fix itself. Now, all my keys work, I can change the volume and hear it and I can even play/pause a song through the respective button. Unfortunately, the screen is just completely off, no backlight at all.
I know this isn't the Nvidia issue since I have an AMD graphics card, but I have run out of options. I booked an appointment at an Apple store, but I'd prefer to fix it myself. It seems like it is a problem with the graphics card though, maybe a loose connection. Does anyone have any idea what it could be? I typed this on my phone BTW, so sorry for any typos (I tried to correct everything).

Were you able to perform a Safe Boot? What you're describing could be a hardware or software issue. If you're able to do a Safe Boot, it's more likely a software issue. To perform a Safe Boot, hold the Shift key down right after you hit the power button and keep holding it down until a horizontal bar appears below the Apple on the gray screen. This will perform special diagnositics/fixes and boot the Mac with only essential kernel extensions.
The vertical/horizontal lines are, however, really suggestive of a hardware problem, like a video card defect or defect in the connection of the computer to the display.

Macbook Keyboard not working in Bootcamp (XP SP2)

Hey all,
Booted into XP just now, have no Trackpad or Keyboard (on a Macbook so that's all there is...). Works fine in OS X.
Any advice? Searched, but all I could find was about external kb's.
Reinstall BC? Using 2.1 atm..
Cheers.

You should probably post your question in the Boot Camp forums:

Macbook keyboard not working in X11

I just installed arch on my macbook 2,1 and I got X11 to detect my screen, but the keyboard doesn't work. i.e. absolutly NO input.
The only thing to do is to emergency shutdown. I haven't really done anything to my xorg.conf except set the keyboard model:
Option "XkbModel" "madbook79"
Any Ideas?

I believe this will solve your problem: http://wiki.archlinux.org/index.php/Xor … otplugging

Keys on external keyboard not working

Hi folks,
I recently purchased a USB keyboard (extended numeric) for my MacBook Pro, and all has been good until this morning, when the V and Y keys (both lower and upper case) have stopped working, i.e. when I try typing with them, nothing appears. With the V key, the Edit button flashes, and nothing happens (that I can notice, anyway) when I try the Y key. (Thankfully my macbook keyboard is all okay.)
I wondered if the keyboard might have shorted, but all other keys are working okay.
Any thoughts?

Yes, the built in keyboard works perfectly well, both with the external keyboard connected and disconnected. I'm hoping the external one isn't beyond help... it's such a pain to have to replace!

MacBook pro Keyboard not working after coffee spillage. Possible replacement?

Hi there,
4 days ago I spilled coffee (nescafe with sugar, no milk) over my Macbook (mid 2012 non-retina). I turned it off instantly and I've put it upside down. Then I opened it and I started to dry the notebook.
I had few attempts to turn on over the weekend, only one successful, so I gave it a rest until today.
Today I did complete teardown of the laptop with a friend, I sprayed all of the parts with special electronic-contact spray and I was able to turn it on sucessfully.
However I figured out that when I turn the laptop with keyboard connected (regular MacBook keyboard, not external), then there were 90% chances that it will turn off before even booting.
So I spilled ethanol over the keyboard few times, sprayed with the same spray, but no luck. It seems the keyboard is making some non-desired contacts with some electronic part.
The laptop is working without a keyboard, but I would like to change it if possible.
Is there a possibility to change the keyboard? I don't have official Apple store in my country, so I was thinking maybe ordering from ebay. Any suggestions on where I can order a keyboard?

Liquid Spill
If you believe you’ve spilled anything (water, soda, trendy energy drink, etc.) on your Apple notebook, shut it down immediately, lest you continue short-circuiting your computer and thus blasting small holes through its components. Just because your computer works for a while after you’ve spilled liquid on it doesn’t mean you’re in the clear. Damage from liquid spills start out small and difficult to diagnose, and then over time spreads to become larger functional issues.
The best thing to do in this case is to take your Mac to an Apple-authorized service center. But if you are feeling handy and are OK with voiding your AppleCare warranty (AppleCare does not cover accidental damage), you can clean your computer yourself. Unplug it, open it up, and disconnect the battery and all connections to the logic board. Then sit the open computer by a fan while gently scrubbing all sections of the logic board with cotton swabs and isopropyl alcohol. Clean both the top and bottom of the logic board if possible, then let the exposed MacBook dry in the path of the fan overnight before piecing everything back together and turning the computer back on. With any luck, the crisis will be over.

Thinkpad keyboard problem - some keys generate multiple keys when pressed

thinkpad keyboard problem - some keys generate multiple keys when pressed
For example, "t" generates "tr", "y" generates "yu", "backspace" generates "backspace" plus "IBM access connections", "m" generates "mn" and "n" generates "mn". Not all keys are wrong.
For what it's worth, the odd behaviour started shortly after a trip to Miami in which I had a meeting at a cafe in which we were undercover but it was pouring cats and dogs - it was like having a meeting in a sauna - so I am wondering if the high humidity could have caused the behaviour.
I tried replacing the keyboard but the new keyboard has the same problem.
The machine in question is a Thinkpad T23 running Windows XP Pro
Any help would be appreciated as I am now in Los Angeles using a borrowed Mac! :-)

i have something along the lines of the same problem.
http://bbs.archlinux.org/viewtopic.php?id=56777
my conclusion is something in the last system update screwed it up.

Satellite L750/04K Keyboard not registering every keystroke

I have just purchased a L750/04K laptop but the keyboard does not seem to be registering every keystroke.
Often you have to press the space a couple of times, or other keys as well.
It doesn't matter how fast or slow I type it happens randomly.
Any help resolving this would be greatly appreciated.
I am using windows 7 in 64bit mode.

Hi buddy,
Have you noticed the same behavior with external keyboard? Probably only the internal keyboard is malfunctioning and so not all keys will be recognized.
Also check the current BIOS version and have a look on official Toshiba website for an update:
But if an external keyboard works properly the internal keyboard must be replaced. During valid warranty time it can be done for free from an authorized service provider.
Check this!!!

SAP Note 0407563: Key Figure Model versus Account Model in BW

I am reviewing a document on Key Figure Model versus Account Model in BW.
There are a number of references to "SAP Note 0407563", can anyone with access to this note post it here for me to review. Sometimes some otf there links prompt for password.
Thanks in advance.

Hi,
<b>SAP Note 0407563</b>
Symptom
You would like to design a data model for SEM-BPS and you are not sure, whether to use the key figure or the account model.
You are looking for proposals for data modelling.
Additional key words
bps0, key figure, characteristic, model, data modelling, consultation
Cause and prerequisites
In the following you find a simple example by means of which the terms key figure and account model are defined.
In the example we want to assign several key figures (for example revenues) to a characteristic (for example customer), whose units (for example currency DM) are identical.A modeling option, which is called key figure model, contains all key figures in one data record.
Customer Revenue_1 Revenue_2 Revenue_3
A 10 DM 30 DM 50 DM
In the account model, on the other hand, an additional characteristic is added, which separates the revenue types.
Customer Type Revenue
A 1 10 DM
A 2 30 DM
A 3 50 DM
Advantages and disadvantages from the point of view of data modelling
You can easily add an additional revenue type in the account model, because you do not have to change the data structure.In the key figure model, on the other hand, you must add an additional key figure to the structure.It actually depends on the frequency of these changes occurring.
A data record that is to be changed by a processor, is exclusively locked by SEM-BPS for this processor.A lock that only concerns individual key figures of a data record is not possible.As a consequence the different revenue types can be changed simultaneously by different processors in the account model, wheras in the key figure model one processor automatically locks all key figures exclusively for his own use.
If you use a planning function in the account or key figure model, a different Customizing is required in general. Consequently, a conversion of the data model leads to a change of Customizing in general.
Advantages and disadvantages from the technical point of view
The transaction data is stored in the BW.Analyses have shown that the read time basically depends on the number and not on the size of the data records.In the above example you can see that by changing the key figure and account model the number of records increases by factor 3, which means that you must expect longer read times.When determining the factor you must take into account that normally not all key figures are used in every record in the key figure model.As a consequence only those records are created when changing to the account model, for which the key figures are not equal to zero.
Example:
So if in the above example the key figure Revenue_1 is not used, only two records are generated and consequently the value of the factor is also reduced to 2.
After the transaction data has been read from the BW, it is stored in the application server's memory.The amount of memory required depends, among other things, on the number and on the length of the records.The length can be influenced by the data model you choose:in the key figure model the records are longer than in the account model and therefore consume more memory for each record. Therefore, the key figure or account model will require less memory depending on the relationship between record length and number of records.
When the data model is changed, also the planning functions must be revised.Depending on the type of calculation there might be advantages for one of the models.
Example and rules of thumb
The following example contains 30 key figures, which were mapped to 3 key figures and one additional characteristic with a maximum of 10 characteristic values when you changed to the account model.In both models a price calculation between three key figures each was executed.Consider the specifications in the table as relative specifications:For the number of data records you for example find a and a*10.This means that in the second case the number of data records is larger by factor 10 than in the first case.The determination of the relationships is based on 5000 data records in the key figure model.
Example: all key figures are used (100%)
measured size      :     Key figure model, Account model
Number data records:      a      ,     a*10
Read time       :     l      ,     l*10
Price calculation:      t      ,     t*9
Data record length:      d*4      ,     d
Memory requirement :     m      ,     m*3
Example: Key figures are partially used (20%)
measured size      :     Key figure model ,Account model
Number data records :          a      ,     a*2
Read time           :     l      ,     l*2
Price calculation      :     t      ,     t*2
Data record length      :     d*4      ,     d
Memory requirement      :     m      ,     m*0,8
How are the sizes determined?
Read the related notes for details on the use of the statistics.
1. a: In the statistics of SEM-BPS or BW this value is stored when you execute a planning function. The method has the name 0-DB1.
2. l: The above statistical record also contains the execution time.
3. t: In the statistics of SEM-BPS a record is stored for the planning function.The overall runtime of the planning function contains the database time. Therefore the database time must be subtracted from the runtime of the planning function to determine t.
4. d: The data record length corresponds to the data structure length (ABAP length), which is generated for every area.The name is made up as follows:
Prefix: /1SEM/_YS_DATA_
Client: mmm
Name of the area: gggggggg
The client must always be specified with three digits, the area only in its actual length.The name for an area called 'MYAREA' which is in client 001 is for example /1SEM/_YS_DATA_001MYAREA.When you determine the length, note that there is the dictionary and the ABAP length (Transaction SE11 => Extras => Structure width => ABAP length) and that the total of the two structures contained must be determined.In the structure stated above, for example /1SEM/_YS_CHAS_001MYAREA and /1SEM/_YS_KYFS_001MYAREA are contained.The total is the length you are looking for.
5. m: After executing the planning function, start Transaction STAD and find the appropriate statistical record for the dialog step, in which you have executed the planning function.The record contains a memory specification, which is the desired value for s.
Solution
Bear in mind that the values from the example are not generally valid, but were determined from a specific example.We recommend that you determine the parameters (both the values of the variables and of the relationships) for your specific case and to use it as the basis for discussion.You should not choose too few data records, because the fixed memory consumers predominate otherwise.

TS1381 My left arrow does not work on my macbook pro(model A1226). I have reset nvram, performed a safe boot, pulled the cache to desktop, replaced .globalpreference.plist, test all other keys with keyboard view (all others work) - HELP!!

My left arrow does not work on my macbook pro(model A1226).
I have reset nvram, performed a safe boot, pulled the cache to desktop, replaced .globalpreference.plist, & tested all other keys with "keyboard viewer" (all other keys work except for the arrow).
In addition, I have gone thru all the recommended checks with universal access and have booted from snow leopard dvd and the left arrow still does not work.
I have tried using the left arrow key in all of applications I use such as: excel, ms word, address book, calendar, iphoto, terminal, & highlighting an icon and using the arrows to move to another selected icon.
Here is the kicker! In addition, I purchased a logitech solar bluetooth keyboard and the arrows work fine with my ipad but do not work when paired with the macbook pro. All other keys work fine on the macbook pro using the bluetooth keyboard.
I believe this says that the problem is not in my macbook pro keyboard. So where can it be?
Can anyone think of any other rabbit holes I can search?
thanks and regards
vats3

I would also like to add that I've reverted the two cd drive and hard drive mods I did and the laptop is back to factory hardware and there is 0 corrosion or mold visible.
