Won't power on/turn on USB keyboard

I just got this G5 Tower and it boots to the screen indicating that there's not OS/boot device (pardon my limited Mac knowledge). I'm trying to get it to boot to an OS X install disk (no hard drive present, I want to see that it will manage to boot to that disk before I spend the money on an HDD). The problem is that the keyboard doesn't get power. Sometimes the lights will blink at first then it goes dead. The weird thing is that a USB mouse powers up just fine. I have no idea how to troubleshoot this; do I need an Apple keyboard? Are only some PC USB keyboards compatible? Right now there's no HDD in the system and Id just like the assurance that it can at least boot to disk before I buy a HDD for it.
Thanks in advance for any help you can provide!

The current state is that it can boot to my Install DVD now
Great!
Do you mean the Installer doesn't see it, or Disk Utility doesn't see it?
Did you format it HFS+ yet?
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the Erase tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled.

Windows XP won't boot, turns off USB keyboard

Hey Macfolks,
I'm running the latest Boot Camp on a 21" iMac (3.06 GHZ) and Snow Leopard. Windows XP (service pack 3) ran great the first time I installed it using Boot Camp assistant, but...
Now when I try to boot to Windows I have two problems:
1. It won't boot up, but freezes on a white screen.
2. It kills the USB keyboard. The keyboard and mouse running through it just stop working.
I can get the keyboard back if I restart, hold OPTION then choose the start up disk -- which I'm shocked works at all because the moment the OSX login screen comes up, the keyboard's frozen again -- then unplug the keyboard, restart again under OSX and plug the keyboard back in to get it working once more.
Honestly, I just want Windows to boot up like it's supposed to. Does anyone have any suggestions?
Many thanks!

I heard a rumor that Windows XP has trouble with iMacs and the new Boot Camp. Can anyone confirm or deny this?
Thanks!

DV2000 has a bad hdd that won't power up

This DV2000 i'm working on has a bad hdd that won't power up & used a usb device to clarify the issue.
Shouldn't the system bootup to bio's even though the hdd is gone?
Worked on alot of desktops & I know they should boot to bio's so you can set the hdd to auto.
This thing now won't even bootup to the bio's, just a black screen with all light's lit up on keyboard & on front.
It beeps 2 short beeps (very low beeps). No loud annoying beeps like i've read on here & the support site.
I'm pretty sure it's not a overheating gpu issue.
Hooked it up to an external monitor & stll won't show a screen as long as I entered the right keys.
Thank's for any comments you might have.
David

First thing, see if it will boot into the Recovery Partition: Hold down Command R at restart.
If it boots up there, then it's likely that the hard drive has failed, or simply doesn't have a working system.
If it doesn't boot up there, then it's likely to be some other part of the hardware.
If it is the hard drive, then this can be replaced. You can find videos showing you how to do this on sites like ifixit.com.
Then you can just restore all your data from your backup. You do have a backup, right?

The reason i flash is for compatibility issues
If an issue is noted, now that you have found the forum, before a flash, many times answers may point to something other than a UEFI/BIOS problem. Anyway, if you have the Intel ME driver, chipset driver, and USB Renesas 3.0 driver installed, there are no UEFI/BIOS settings other than enabling all the USB 'enable' options. In this situation, when a keyboard did work, and then didn't with a flash to a newer release UEFI/BIOS, MSI needs to be made aware of this so they can address it in an upcoming release. Again, if there are no compatibility issues experienced with an existing/older UEFI/BIOS version, there is no practical reason for flashing. It is not a driver.
If and when a flash is required, please use the forum's USB flasher found here at this link;
https://forum-en.msi.com/index.php?topic=108079.0
After a flash, it is also recommended to do a full battery removed CMOS clear and reset.

MacBook Air 11-inch, Mid 2013 won't boot with external USB keyboard

Hello,
Just bought a MacBook Air 11-inch, Mid 2013 (8GB, i7, 512GB SSD) today.
All available software updates are installed (OS X 10.8.4 (12E3067)).
Also have a Macbook Pro Retina.
If I connect a external USB keyboard (Kinesis Advantage Pro USB) to the Air then it don't boots.
If the keyboard is connected directly to the Air USB port then it don't shows the Apple logo on grey background after power on, just give a endless loop of the turning on sound.
If the keyboard is connected to the Thunderbolt display then same empthy grey screen after power on and no sound at all.
The same keyboard and Thunderbolt display work well with my Macbook Pro Retina and a Macbook Air 2011.
Any ideas ?
Thanks,
Karsten

I like it very much. I use it on my iPad (and occasionally my iPhone). I'm kind of a keyboard snob actually. I tried the Apple wireless keyboard first. Apple keyboards have a short throw that hurts the tips of my fingers. They're very pretty but the on button turns on when I don't want it to and my iPad wakes up in my bag. Strike 1.
I went to a little keyboard called the Joy and it had a positive switch so I didn't have the wakeup problem. It worked well though after several months I wore it out and had to replace it with another one. I also didn't like how flat it sat and used rubber bumpers on the back. It too had a short throw that hurt my finger tips after a while but it was better than the Apple.
Then I discovered the Logitech bluetooth keyboard, the K811. This is a great keyboard. It switches between multiple targets with one press, it has a positive on/off switch, the keys light up, it's rechargeable and lasts a long time, and the slight cushioning on the keys keeps my fingers from hurting. I put the rubber bumpers on it though like the Joy because I like the keyboard to sit up a little. It's a tiny bit bigger than the other keyboards but I like it a lot, better than my MBA keyboard and better than my iMac wired keyboard. I'm trying out an after market keyboard on the iMac now but I'm thinking about switching to one of these for the iMac.

Is there a way to use an adapter to connect my ipad to a USB keyboard and to an ACDC for power

I have a tablet keyboard with a male USB plug attached to it and it came with an adapter with a female USB on one end and a mini male USB on the other end. I was wondering if there is a way to use that keyboard with my iPad and iPod? There are adapters that plug into laptops and pc's that you can plug keyboards and mice into. Will it work if I plug the iPod or iPad into one and the keyboard into one and then plug one into the ACDC power adapter (since I am sure the keyboard will drain the battery quicker). I am so tired of the iPad keyboard always hiding what I am trying to type.

As far as I know, there isn't any support for USB keyboards. THe iPad is designed to work with blue tooth ones.
That power issue that you state is why it likley won't work. An update in 2011 reduced the amount of power allocated to the charging port and I don't think it's capable of outputting enough to run a keyboard.

Using Apple USB Keyboard Extension Cable for Power

I have a USB keyboard extension cable. Part number is 591-0079. Can I use that to extend the power cable for my iPad when it is plugged in? Can I also use it for my iPhone?
I wanted to check first to make sure because it predates the iPad and the iPhone.
Thanks any advance.

So there won't be any problems transferring power through it? It will charge iPad and iPhone without any trouble?

1st gen 4GB nano won't power up with USB

My new-to-me old Nano doesn't work on battery power, even after new battery installed, but powers up and plays when docked onto speaker. No big deal, and merely mentioned as a possibly related symptom...main issue is that it won't power up using USB cable to PC. My other nano works fine with the same cable. The bad one gives an Apple logo, then backlighting flashes on for a mere fraction of a second and then it shuts down. Then about three seconds later it all repeats again. There's only 25 songs on this 4GB model. I could care less about this problem if only my music was already loaded onto it. It cost me $15 on ebay and $5 for a battery, so $20 into a useless unit bites. $30 could have gotten me a good working one...hopefully this can be revived for cheap?

Well, I tried to other things... I turned off the backlighting to see if less current draw would help. It didn't. Also, the backlighting option gets deleted off the main screen menu after it dies/reboots.
I also tried connecting to PC with the ipod screen ribbon cable disconnected just for kicks...still a no-go.
I just want to load it up with songs...sigh.

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!

G5 dual 2ghz. Been unplugged for a while. Powers up but no video or power to usb keyboard. Boots up fine in safe mode, restart into normal mode ok. After shutdown, back to same issue. What's happening?

G5 dual 2ghz. Been unplugged for a while. Powers up but no video or power to usb keyboard. Boots up fine in safe mode, restart into normal mode ok. After shutdown, back to same issue. What's happening?

I keep seeing people ask and the advice to replace if it has been unplugged, but really have nothing to confirm that from my experiences.
My experience is that a weak or dead battery can cause much more than date and time issues.
I have seen it time and time again.
Deal with used machines and you will quickly learn....
I'll give no "recipe" or set list of symptoms, but the range of irregularities that can occur make it a quick and easy first line of troubleshooting, especially when the machine has been off the mains for a few months.
Why fight mysterious maladies and troubleshoot with the knowledge that the PRAM battery is beyond it's useful life.
Maybe they recharge?
Not likely. They are chemically nasty, disposable, one way discharge batteries.
They aren't Lithium-ion batteries

My kid just got an iPod 5th gen (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line and lightning symbol. No other response at all.

Sorry about the long title.....its my first post.
My kid just got a brand new iPod 5th generation (today from Santa) and it won't power up or charge. The only response is when I connect the USB and press the power button or front button the Battery appears with red line on left and lightning symbol below. There is no other response at all no matter what I do, including holding both buttons down for extended period. My other kid got one and it works perfectly.....I have interchanged usb cables ports etc. but still no response....I would really appreciate any help.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Make an appointment at the Genius Bar of an Apple store since you have a hardware problem with the iPod. This is because as you said the same cable works with another iPod.

My usb keyboard is no longer detected after the power was switched off

I sometimes relocate my Imac to another office and after the power has been switched off the computer no longer detects my usb keyboard.
This had happened several times now and sometimes it all of a sudden starts working again after a couple of hours (but it doesn't now).
The computer keeps searching for a wireless keyboard which I don't have. I have tried everything from switching off power again to reboothing, but nothing works. I have checked all USB ports with other devices and they all work. The problem is not the keyboard itself, because it does work when I plug it in to my MacBook.
Anyone recognize this?

Yes, to a blue tooth mouse only. I have tried disabling the blue tooth connection, but when i restart my computer it automatically connects again.
I got the keyboard to start working again now by pressing all the keys one by one (in order to discharge them, read that somewhere). I helped. But how annoying is that?!

I have a macbook and when I power it on and then select myself as a user...It won't power up. It stays in the white screen with the apple logo. I am online currently under 'guest user'. Is there anything I can do from the keyboard to fix this??? Help!!!

Could you specify the model of MacBook and the OS X it's running, please? Some of the advice or references vary along with the system, so this could be helpful to formulate a reply. I've never used a Guest User selection, but do have more than one User.
If the computer does not have an optical drive, you may be able to boot it into a recovery disk mode or something; in an attempt to see what is wrong and maybe fix it.
Good luck & happy computing!
