Wireless keyboard/mouse unable to wake imac

I am currently using a iMac G4, D-Link DBT-120 vers B3 and have been unable to wake computer using wireless keyboard or mouse. Once computer is awake (using wired mouse) keyboard is fine. I have tried updating bluetoothversion but am told it is current, firmware tells me it has errors and to try again. In bluetooth preferences allow to bluetooth device to wake is light grey. I have followed advice in reference article about this issue and downloaded update of 10.4.6. Since the update I have not discarded .plist as suggested in anearlier discussion. Any thoughts or am I to have some wires across my desk for the mouse?
Thanks

Hi again, Mheader —
Please accept a (belated) welcome to Apple Discussions.
Sorry for not responding to your post in diga's "Bluetooth Keyboard - Wake Up Powerbook doesn't work anymore" thread. I appreciate your initiating a new thread, so we can focus on your situation. "Any thoughts or am I to have some wires across my desk for the mouse?"Let's hope we can make some progress toward a solution...
(1) When you say, "... firmware tells me it has errors and to try again" —— I think it's likely that this is the problem, or part of it. I don't have a D-Link DBT-120 adapter (your is one of the correct models), so I have to depend on the experience of others about (part of) this issue. Here are the steps for updating its Bluetooth firmware:
(a) Download Bluetooth Firmware Updater 1.2 [11/23/04]. Note that — as with any software installation — it's very important that the process isn't interrupted; don't work on any other activities while it runs, ensure an uninterrupted power supply, and make sure that Energy Saver is set to Sleep = "Never" while the installer is running. The download will place a file named BluetoothFWUpdate1.2.dmg into your Downloads folder or wherever your browser is set to save downloads.
(b) When you open this, and double-click to "launch" the enclosed BluetoothFirmwareUpdate1.2.pkg, it acts a little differently than many software update installations — there's an extra step. This (the installer actually runs) creates a file in your /Applications/Utilities/ folder named Bluetooth Firmware Updater. At this point, you're done with the .dmg image and can dismount it.
(c) Now double-click to "launch" the Bluetooth Firmware Updater application that I've just described. This begins the actual upgrade process = "flashing" the Firmware. (The Apple Installer runs again.) Since you're using a D-Link DBT-120 Rev. B3 adapter because Bluetooth isn't "built-in," the adapter needs to be plugged directly into one of the USB ports on your iMac (not a hub). Since the Firmware Update is only "flashing" the module or adapter, you should "disconnect" your mouse and keyboard during the process. The installer itself may provide an alert and do this for you. (It did this when I updated my internal module's firmware.) Follow on-screen instructions from here.
(d) As I understand it, installing the firmware on an adapter may take a very long time — I've even seen it suggested that you let it run overnight.
(e) You should clearly be able to see that the update has been successful: if an alert that the device wasn't updated appears, the process wasn't successful. If this occurs, participants with a lot of experience with adapters suggest "try, try again." (Here's an example.)
(2) You may want to read through Wake This Computer Option Is Shaded and Wake This Computer Option Is Shaded, Part 2 — which are examples where several folks were able to solve similar problems using this approach.
If the firmware update is successful, but this problem remains...
(3) Try USB device troubleshooting: USB controller problems caused by some non-compliant devices can sometimes cause the problem you're experiencing.
I hope this helps!
Please post back to share how it goes.
Regards,
Dean

Using powerbook keyboard/mouse to interact with imac

i have seen similar questions to this, but nothing exactly like what i am doing.
my problem is as follows...
i have an imac (2009 edition) hooked up to my television. the imac is in a bedroom and the tv is in the living room, so whenever i want to switch what is being sent to the tv, i have to go into the bedroom to do it. one solution to this would be to buy a wireless keyboard and mouse (easy enough). what i am wondering, however, is if it is possible to use my powerbook, which sits on the coffee table in the living room, to control the imac. i dont need to see the screen of the imac since it is on the tv in front of me, i just need the key strokes i hit to register on the imac, and the mouse movements to apply to the imac and not my powerbook.
i have read suggestions about using synergy, which allows one keyboard and mouse to control two computers. this could be what i want, but i want the powerbook control over the imac to be temporary, so that when i am in the bedroom, controlling the imac, i can use the imac keyboard and mouse.
does anyone have any experience with this or ideas of what i should do. it would be nice to re-use my powerbook and save $100 by not getting a wireless keyboard/mouse.
thanks!

It would need to be running Leopard, yes - and the iMac disk will be machine-specific and won't work. You can still, however, use VNC, which is the basis for Screen Sharing. On the iMac, go back to Sharing, Remote Management, Computer Settings, and tick and set a password for "VNC viewers".
Then, on the laptop, install Chicken of the VNC, launch it and locate your computer in the Open Connection dialog. You may need to add its address manually. Enter the VNC password, and you will be able to control the iMac.

Windows 8.1 freeze on any hardware scan or changes. USB wireless keyboard mouse not working

Problem : System Freezes frequently on any hardware scan or changes.
Symptom : Wireless Keyboard Mouse not working.
Caused by : VMkbd.sys located in C:\Windows\System32\drivers.
Issue : VMware player or VMware Workstation installed on Windows 8.1 causes compatibility issue leading to system freeze
Soultion : Please follow steps below
Step 1: Start > run > regedit
Step 2: Locate to this registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-BFC1-08002BE10318}
Step 3: On the left side plane, Right click on the registry {4d36e96b-e325-11ce-BFC1-08002BE10318} and then export it as backup. Just to be safe.
Step 4: Edit the UpperFilters, The value current would be kdbclass vmkbd. Remove the vmkbd. So only value left would be kbdclass.
Step 5: Restart your system and connect your USB wireless reciever. If all is well it will not freeze your windows now.
This worked for me. Hope this works for you. Enjoy..!!

Wireless keyboard stopped working on my iMac

My wireless keyboard stopped working on my iMac. It shows that it is connected, but it won't respond. It's not the batteries, and I tested keyboard on my iPad and it works fine on the iPad, so it is not the keyboard itself.
I also tried to connect a different wireless keyboard to my iMac, but the same thing happens... it shows that it is connected, but it doesn't respond.
When I go preferences > bluetooth, the device shows as connected. I have tried to remove it by highlighting it and clicking the - (minus) , but the - (minus) is not clickable. It is gray.
Also grayed is the box that says 'discoverable'. the box is checked however.
I am at a loss!! Any ideas

Wireless keyboard & mouse

Hi there. I just installed on my MBP Mac OS X 10.5. I wanted to install WinXP as my secondary OS with BootCamp.
My wireless keyboard & mouse are not detected when I boot in Win.
How can I get my keyboard & mouse to work
Thanks!

A quick look at the requirements for the Apple wireless keyboard and mouse says nothing about Windows, meaning they are not supported by Apple for Windows use. That does not mean, however, that someone has not found a way to make them work. As Allan has already stated, the Bootcamp discussion area would be a good place to look. It is possible that there is a third-party application which allows them to work in the Windows environment. Good luck.

Hp model #RK713A wireless keyboard + mouse

can i purchase a usb dongle that will work with my hp model #RK713A wireless keyboard + mouse?

I am also looking to buy the dongle for this set up. My son got one and then shipped to boot camp (USMC) and now we can't find the dongle. It is a beautiful and new set up except for the missing dongle. I hate to buy a whole new set up.

Impossible, there are zero, as in none, zip, nadda viruses for OS X. If you have viruses on it they are for MS Windows and will not affect OS X. I suspect the hard disk has crashed, if you have backup then it's not a big deal to have it changed, just take it into your local Apple Store or AASP for service. If you have not been backing it up you may be in for a painful lesson on why backup is critical.

Can't wake mini w/ wireless keyboard/mouse!!

My new mini is great, but when it sleeps I can't wake it up! I'm supposed to be able to hit any key or move the mouse to wake it up, but nothing happens. I'm using a Gyration cordless keyboard and mouse. They seem to work fine when the mini's awake, but once it sleeps, there's no way to wake it back up without hooking up a corded keyboard.
Any suggestions?
TIA!
Keith

Thanks for the replies!
Repeated entries (on any key) don't work. I don't see a power key on the wireless keyboard. Originally, the "Allow Bluetooth devices to wake this computer" was unchecked, but checking it doesn't seem to have helped (I'm pretty sure the Gyration keyboard & mouse aren't Bluetooth equipment).
The mouse & keyboard share one receiver in a USB port. The Gyration equipment has never successfully awakened the computer, but I've only had it one day. This is also my first day using the peripherals. My wife used them in her classroom and said they were o.k. She no longer needs them, so I figured I'd try them w/ the mini. I'm hoping to find a better solution than unplugging the receiver every time the computer goes to sleep.
Any more ideas?

No sound from iMac with a wireless keyboard/mouse

I just installed FaceTime on my iMac and am able to hear a friend who calls from her iPhone, but she cannot hear me. I have a wireless keyboard and mouse with this Mac. Does that have anything to do with it? If so, can it be fixed and how? Thanks!

(1) Have you checked your FaceTime > Video menu command to be sure that you have selected your iMac's built-in microphone?
Also check  > System Preferences... > Sound > Input to be sure your iMac's built-in microphone is selected as your system's "sound input:" device.
(2) If the problem remains, both of you should test FaceTime with at least one other person to try to determine which of you has the problem.

When i boot my mac it opens with a grey screen and the wireless keyboard, mouse illustration and won't do anything elsens,

When I turn on my iMac (27" intel) all I get is connect my wireless keyboard and mouse on a grey screen. The mouse will connect (sometimes) after I wiggle it a bit, but nothing from the keyboard. After a few minutes the disk utilities box comes up. I ran permissions and repair permissions, verify and repair on my computer and it tells me everything is ok. But it won't let me past this screen. Any suggesions? Help!?!

Hi Grace Be,
Welcome to the Support Communities!
The articles below may be able to help you with this. I've summarized some of the key points below for you. Click on the links to see more details and screenshots.
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/TS2570
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Perform a Safe Boot
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
If your Mac starts up as expected, immediately try restarting.
If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
Reset the NVRAM / PRAM
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Reset the NVRAM / PRAM.
I hope this information helps ....
Have a great day!

Cannot come out of standby w/ wireless keyboard mouse (usb)

For some reason I cannot get my mega 180 to respond to keyboard or mouse activity when in standby (wireless mouse/keyboard via usb). In ther device manager, the options to "allow this device to bring comp out of standby" is grayed out. Any ideas?
Something else I have noticed that might jog someone's brain: I have a touchscreen monitor that connects via a 9 pin adapter (it is made for a serial port) to a usb port. When I bring the computer out of standby by pressing the power button, I lose the touchscreen function, and can only get it back with a reboot.

Wireless keyboard needs pairing with my iMac

I changed the batteries in my wireless keyboard and now need to pair it again with my iMac. However I need to type in my password to wake up the computer - which I can't do without the keyboard! Any ideas?

Hi Charliecornwall,
When changing the batteries on an Apple Wireless Keyboard, the computer should maintain the pairing. If it does not, you may be able to restart the computer, and if it does not detect a paired keyboard, it should prompt you to pair it. Alternately, if you have access to a USB keyboard, that may also be used to bypass the wake screen password so you can pair the wirless keyboard.

Wireless Keyboard & Mouse Compatiblity

Im about to buy the apple Wireless Keyboard and Mouse that came with the G5 iMac, would i be able to use that with my iMac? and how?

Im about to buy the apple Wireless Keyboard and Mouse

Hi-- I just got a wireless mouse that connects with the Bluetooth (included inside the G5; depends on the kind of iMac you have . . . you'd need to get a Bluetooth adapter, if your iMac is older, and doesnt have bluetooth pre-installed).
Took me about 2min. or less to go through these simple steps:
1) batteries installed > flip on power switch (underside of mouse)
2) go to the G5 System Preferences > select "Bluetooth"
3) follow directions to turn bluetooth on, detect a new device, etc . . . it's that simple!
(you might need another wired mouse / keyboard to go thru this setup, but i'm not sure -- got mine secondhand)
Have fun!

Wireless keyboard AND Password logon on iMAC

I am a new Apple user with a MacBook Air and a iMac for professional use and I just ran into the problem that my iMac, configured with password protection, went to sleep and my wireless keyboard lost its pairing because I paired the keyboard with my MacBook Air. The mouse is working on my iMac but I cannot logon because I cannot type the password. Apple's solution is to go out and borrow or buy a wired keyboard or USB wireless keyboard and then you can logon. That is a kludge!
Apple, Hey Apple, I don't want to be the Annoying Orange but wouldn't it be much more elegant and friendly to have an on-screen keyboard where I can 'type' the logon password with my mouse? In the wireless era problem recoveryshould be made easy. Just a 2 finger or right finger click and the keyboard option pops up. Almost everyone has a wired or a USB mouse laying around but not a 'spare' keyboard. From a company that sells high-end, user-friendly, expensive, tools for our private and professional life I expect more. BTW as a 20+ year user of MS I do like my Apple tools but found some productivity and efficiency limiting bugs that really should have been resolved years ago. I will post those in the appropriate forums.

Netflix app is not populating at all on my 55l7200u anymore. We had Toshiba support come out yesterday to replace a board in the tv to stop a whistling sound coming from the tv and now Netflix App is not working. We press the button on the remote and the screen goes black for 2 seconds and then automatically jumps back to cable. We've tried resetting the factory settings, updated the firmware last night and still nothing. It's not even coming up with an error. When we go into the settings and look for information, we found a 'Netflix setup' but there is no Netflix ESN and 'Deactivating' Netflix option does nothing. The other App we use is working correctly (you Tube).
Please help.

Wireless keyboard & mouth on Rev A iMac G5.

Hi folks,
As you know, I have a Rev A iMac, which did not come with the Bluetooth module installed.
How do I go about getting the iMac set up for the wireless keyboard and mouse? Is it an internal part I need to buy or will it be an external receiver for the Rev A's?
Cheers.

Optimus...I use Logitech's MX 700 wireless keyboard and the MX 1000 Laser mouse. It is 'RF' technology instead of Bluetooth...both have worked flawlessly for over a year now.
I also believe that you can install an Airport module in your iMac yourself.For Bluetooth connection on your iMac I pretty sure you have to purchase a Bluetooth Dongle that pluggs into one of your iMac's USB ports.I did not use either of those options.
