Wireless keyboard stopped working, flashing green light (not batt. related)

Hi, I had the exact same problem, and I found to fix it.

I think this issue will be caused by an electric loose connection of AA batteries and wireless keyboard.
The design of power supply unit is very poor due to focus on slim and cool design.

Please try to pack the metal that conducts electricity between the last AA battery and lid of
the keyboard.
I placed the spring of the metal, and then this issue was fixed.

I hope this issue is fixed in your environment.

P.S
I think the problem that the keyboard connection is often lost and the problem that mouse tracking
is very slow at the time are different.
A latter problem is easy to fix.
Could you please turn off airport (802.11b/g). I think this issue will be the software problem of Mac OSX.

Just to add another voice, I had the same problem. Apple 'helpfully' suggested that I change certain preferences, not understanding that my wireless keyboard wouldn't work. My new slim, sleek, wired keyboard looks great, works every time, but I still feel a bit cheated by Apple.

And.... another one. The new Apple Wireless Keyboard works.... for a while. I got it paired and working, but it will shut off and/or show "keyboard connection lost" in the middle of a session, for no apparent reason. Very frustrating. The little green light will come on when first connected and will flash a few times, then go out. Sometimes the connection continues, sometimes it is lost. Changing to new batteries does nothing.

C'mon Apple, what's the issue? It's not like you can't duplicate the problem - witness the number of posts here.

Add me to the list. I recently purchased the new aluminum wireless keyboard. I already had the wireless Mighty Mouse, which worked fine with my old Apple Wireless Keyboard with the number pad.

Now I keep losing my keyboard connection. And often the mouse slows down to a ccccdrrraaaaaaawwwwwwwwllllllllllll. I usually have to turn both devices off and then on again. I have no problem pairing each of them, but ever since I added the new keyboard neither one works reliably. It's so maddening when I'm trying to get work done.

There is no other bluetooth device nearby. I have an iPhone, but bluetooth is turned off.

Apple, please HELP!

Same problem... was really frustrated that a manual or troubleshooting guide is nowhere to be found on the apple site for the mighty mouse but fortunately after a lot of browsing i found this post.

Lots and lots and lots of thanx Kate!

So Apple Customer Support replaced the keyboard, saying that it's likely a 'hardware issue' (although I doubted that). No improvement with the new unit at all.

• starts up normally and lights green light then flashes green light 30 sec. or so
• will pair with computer and operate for 1-2 minutes
• "connection lost" and disappears from bluetooth list
• new batteries do not help

Same procedure. Same result. Trying any further would fulfill the definition of insanity. Suggestions, anyone?

To anyone and everyone in this thread:

I have added this exact same issue to this thread earlier. There seems to be tons of people with this exact same problem. Far to many for this to not be from the same source. Does anyone know if Apple reads these things? How do we get Apple to take notice of these messages? Seems like the Apple customer support is oblivious to such a wide spread problem. I will always be a Apple fan and they have gotten great reviews on their customer service but I suspect that that is for newly purchased items and they fall short for later problems that people have. Is there some where else we can write to? Does Steve Jobs answer E-Mail?

i just want to add a me too - my keyboard started flashing the green led and otherwise stopped working just an hour ago. seems like i will have to buy a new one tomorrow.

i do not know if it is because of recent os updates, but i have had a lot of problems with os freezes the last 4-5 months, and now this. i really hope all problems will go away with leopard.

everything is lower case because i am writing this with the software keyboard.

And then it started working again 20 hours later. I'm not entirely sure why, but just before this happened I removed all registered devices from the Bluetooth control panel and started a new search for the keyboard. It was discovered almost immediately, but when I was asked to enter some random number I got no response. I started another search, same result. The third time, however, it just worked, I didn't even have to enter the random number.

Hi just got mine yesterday, it worked fine for about 1hr, I dont have a pairing problem or a battery problem, the software keys still work, but I have no letters or numbers??????
REALLY *****
I have a heap of essays to write!!!!
HELP US PLEASE

OS X 10.5 and I'm still having the same dramas. one thing I did do however was reboot using bootcamp and XP and my wireless keyboard works perfect. So I guess that means I don't have a hardware problem... the whole key board also works during the log on, just so I can put my password in??? any ideas??

Another "me too". First unpaired about 2 weeks ago. Happened again today. Have not installed any recent system updates. Holding the wireless keyboard close to my PB and flicking off/on power while searching for BT devices discovers it and while quickly typing in the pass keys works, recognizes it as my custom-named KB, but for how long? Using it to type this reply - light is not illuminated.

OK - time to bail on this. I've returned the keyboard(s) and given up trying to get an Apple wireless solution to this. Nobody's able to fix this at Apple - Customer Support just knows how to manage shipping atoms back and forth, Applecare's manned by barely post-pubescent, but well-intentioned young technicians who do not know Bluetooth - and I'm not going to spend any more time on this until Apple acknowledges the problem and provides some software that works. Best of luck, everyone.

Hi Brian:

I have exact same issues as you, both with the keyboard and Apple support. The only thing is that I can get my keyboard to connect if I do a complete shut down and restart. I loose it after my machine has been idle for for the day. A compete shut down and restart gets it back. But I have switched back to my wired keyboard and what I see when I loose my bluetooth and I go into my system profiler is that there is no info for my bluetooth hardware. Also there is no Bluetooth icon in my system preferences. The shut down and restart brings the info up in system profiler and my icon comes back and I can use my wireless keyboard. Seems like this is a problem with the bluetooth on the computer. Can you give this a try if you can and see the same thing.

Good news...my keys are working again and I haven't had any freezes...the sad part is I don't know exactly what I did to fix it other than:
1) I upgraded to OSX 10.5 Leopard (the key board still had problems)
2) I went to preferences/ International/ input menu/ ticked the boxes for 'Character Pallet', 'Keyboard Viewer', 'Australian', 'US' & 'US Extended' and 'Show input Menu in menu bar'
3) Then I went to the little flag 'Input menu...' and selected 'show keyboard viewer'
4) Then the amazing thing happened I played on the keys that were working, started going right around the keyboard, then I notice the caps lock light came on and all the other key from then on have worked perfectly.
I hope this might help someone, it has been a big drama for me.
Thanks
Sam.
