IMac OS X (10.5) Black screen,chimes when switched on,light on keyboard and mouse. Have tried few tips to restar it. Still black. What could it be?

Try to start up in Safe Mode. It uses a "one size fits all" display mode, runs one pass of Disk Utility "Repair Disk" as it starts up, then loads with minimal extensions and presents a login screen (even if you normally auto-login). It takes five minutes or more.
If you get a picture, use System Preferences > Displays ... to change your screen resolution at least once.

Try:

- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HT201263 My Ipad worked perfectly and one day it went dead. It won't power up and I have tried the tips online. The screen is black. It has been charged.

My Ipad worked perfectly but one day it would not power up and hasn't in a couple of weeks. I have tried the tips on line and have put it on the charger but the screen remains black.

I suggest booking an appointment with the genius bar, there most likely is a hardware problem with the iPad. Apple will replace the iPad if it is in warranty. If it isn't in warranty they will still replace it with a price

You see a closed lens or black screen
If you see a closed lens or black screen when you open the Camera app, try these steps:
Make sure that there’s nothing blocking the camera lens. If you’re using a case, try removing it.
Force the app to close, then open the Camera app again.
Restart your device, then open the Camera app again.
If your device has a front and rear camera, try both cameras by tapping the camera swap icon . If you see the closed lens or black screen on only one camera, take your device to an Apple Retail Store or Authorized Service Provider for more help.

Did anything happen to prior to your phone acting this way? It sounds like your screen is dead, but it is hard to say without knowing what what the cause.
1) was this a gradual problem? Did the phone screen start dimming a couple months ago and now has degraded or after some event (known or unknown to you), the phone started behaving this way.
2) Can you give more specifics on the problem? You said you have a black screen, but also you can see what you're doing on screen. Is the screen just really dim? Is the screen completely black? Does anything else besides attempting to reset the device cause it to flash white?

IMac Intel slow keyboard and mouse response

I have an iMac running Snow Lepard that within the last two days is experiencing keyboard and mouse delays, about 10 seconds or more and I am seeing the rotating ball. The keyboard is directly attached while the mouse is bluetooth but both experience delays. I can type something and then 10 seconds later it will catch up. Same thing happens if I try to scroll down with either the keyboard or mouse. I do not see the spinning ball during this tim, I only see it when I change applications. I have more than 20 percent memory. I shut down and unplugged for greater than 15 seconds. When it came back up I saw a grey screen with white and black tiny squares.

Hi erahi,
It's not the update that's the problem. That update has been used successfully by millions. What probably happened was that there were some pre-existing issues you didn't even know about and the update exacerbated them. But why are you updating to 10.5.3 instead of 10.5.4?
Let's test this first:
Try starting in "Safe Mode" (It will take more time to startup in Safe Mode because it runs a directory check.)
If that works go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting.
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.

HT3924 can i use iMac keyboard and mouse when it is in Target Display Mode and attached to my MBP?

I can attach my iMac to my MBP via thunderbolt and run it in Target Display Mode, so that itsimply becomes a screen attached to my MBP.
What I really want is for the keyboard and mouse of my iMac to also operate as if they were attached to my MBP, but I cant seem to achieve this.
Is it possible?

Its a wireless mouse and keyboard - dont think I can re-pair the keyboard to MBP since I need it talking to the iMac to enable and disable TDM?
I expected TDM to natively pass through the mouse and keyboard to the MBP, since that is the obvious user requirement. But this does not happen.
So I guess I want a workaround so my iMac keyboard and mouse can drive my MBP while attached via Thunderbolt cable in TDM mode.

I use free Yahoo mail webMail access because folders I created in webmail access doesn't get set up in Apple Mail. While I was searching for post about password and keychain issues, I stumbled on several threads that complain about Mail folder issues, so I'm holding off on Apple Mail.
On the password and keychain issue that your post is all about. I've been using login keychain to save and automatical fill my login screens for a year or so successfully, with Safari and Chrome. Automatic form fill also works for Facebook login. Unfortunately, about 4 to 6 months ago, automatic password form fill stopped working with Yahoo webmail, while still worked for GMail (Safari and Chrome). I tried deleting the password entry for my two Yahoo email accounts to start fresh, but neither Safari not Chrome will even ask me if I want to save the password. I was so frustrated that I eventually installed the keypassX 0.43 (password manager) that is quite primitive sompare to OS X's keychain (when it works). Probably no surprise to you yet.
The surprise, to me at least, is that, for whatever reason, password auto form-fill from keychain started working again for Yahoo webmail login on Safari about 5-7 days ago. Still doesn't work on Chrome!
Two tips I can share, at least with webmail access:
1. Password is save only for one of my yahoo mail accounts. When I login in with my other yahoo account, I get no prompt to save the password, and form fill doesn't work when I try to log in a second time with my other Yahoo mail account.
2. On inspection of my login keychain, I see a webform password item saved for my Yahoo account that works with keychain. The name of the password is: login.yahoo.com(MyAccountName1#). When I open the password item and look in the Access Control tab, I see Safari and Chome are listed as allowed to access this password item..
I also an "Internet password" item with a name of just login.yahoo.com. When I open the the password item, it looks just like the password item created for MyAccountName#1, but the MyAccountName#2 is listed in the Account field. Inside the Access Control tab, no apps are listed in access permission. I added Safari and Chrome to the lists of allowed app, saved the password item.
Now when I bring up the Yahoo login page(by bookmark) on Safari, form fill fills in MyAccountname#1 for name and the proper password and I can login in. When I change the name to MyAccountName#2, the correct password is retrieved and I can log in! Alas, it still doesn't work on Chrome.
BTW, I changed the password item type from "Internet password" to "Web Form password" and saw no difference! I also edited the name to be "login.yahoo.com (MyAccountName#2)" to look like the web form password item that works, but it has no effect either.
From my experimentation, here's my observation:
1. A Web Form password item is created for the first account name(MyAccountName#1) for login.yahoo.com and typed as Web Form password. When I log in using MyAccountName#2, an Internet Password is created, but no applications are listed as allowed to access the password item, even when the password item was created after just logged in and logged out to yahoo with the account name and password for MyAccountName#2.
2. Manually adding Safari as an app that is allowed to use the password item works. Doesn't work with Chrome!
The version of Safari I'm using is Version 5.1.7 (6534.57.2). My installed version of Chrome is Version 21.0.1180.79 beta.

IMac wont recognise keyboard and mouse

Hi
I have a strange problem.
When I am trying to start the computer, Leopard does not recognise my keyboard and mouse.
When i press the power button on the machine the optical light on the keyboard comes on, however as soon as the apple logo appears it goes off. The machine boots to the log in screen, however I cannot log in. If I move the mouse to a different port, the light comes back on, however still does not work.
What is really strange is if I boot in bootcamp, the keyboard and mouse work fine.
Both keyboard and mouse are connected directly to the machine.
Any ideas?

I have the same problem and the same Imac.

Keyboard and mouse won't connect to iMac

This morning, I suddenly lost connection between my 27' iMac and the wireless magic mouse. I had just scavenged a pair of batteries from a remote control the other day and while I wasn't notified of low batteries this morning, I assumed those new batteries must be dead. So I replaced them with shiny new ones and.....nothing. Using keyboard navigation, I tried to re-connect but nothing would work. My next step was a restart. This is where the computer lost the keyboard. So, again, I replaced the batteries in the keyboard and went through the initial bluetooth setup assistant procedure when trying to restart without a keyboard. It would find the keyboard, connect to it and then immediately loose it. I never got enough time to enter the password confirmation the setup procedure gives you. I found an old wired keyboard and mouse and got logged in and I've been playing around with the bluetooth setup assistant with no luck. Both the mouse and keyboard go into "discoverable" mode when turned on (blinking green light) and the assistant sees them but will not connect. For the keyboard I get the message "the pairing attempt was unsuccessful. This configuration of Mac OS X and Bluetooth software could be invalid or unsupported." I'm running 10.6.7, update as prompted and haven't done anything out of the ordinary on this machine recently.
Any ideas?

Paul,
I don't think you did anything wrong. I think it was just "one of those things". Things should be OK now.
Give a shout if they aren't.

HT1752 I have an old iMac (the rounded type with monitor). I need a new keyboard and mouse. Will any work? thanks for any help!

I have an old iMac for 2002....it's the rounded type that has an attached monitor. The software is way outdated (OS X 10) and I only really use now to access 3,000 plus songs and old video of the family. Both the keyboard and mouse no longer work. Am I able to use any keyboard/mouse and plug in using USB? Thanks for any help!

Most any USB mouse or keyboard should work. Borrow one if you can and just plug it in.
If the USB circuits are at fault then you can access via Firewire Target Mode with another Mac in order to get at the files.

Another alternative would be to remove the hard drive and use a USB adapter to access it as an external drive.

I am using Photoshop CS5 on a new iMac with a wireless keyboard. I used to be able to hit F11 to perform a custom sharpening action but now the F11 key is the volume control key and I have tried everything to disable or switch the volume key. I have also tried assigning other function keys to initiate the action. Is there a simple solution to this? What am I missing?

Try unmounting the volume on your iMac using Disk Utility. Then mount it again. You may need to reboot the laptop or relaunch its Finder process (using the Force Quit window) after remounting the drive on your iMac. Remember that no process may be accessing any files on the drive you plan to unmount, or the unmount will fail. Unmounting and remounting an external drive on my iMac made it become visible on my MacBook Pro after it had disappeared.

Macbook pro does not respond to bluetooth keyboard and mouse at login screen

i've seen this question floating around and i don't think i've found one that has been resolved. i'm hoping someone may have an answer by now.
i do not have this issue when i boot into windows 7 (bootcamp) the macbook pro responds to keyboard input and mouse input immediately on the windows 7 login screen. when i boot into mac, there is no response from either. i've seen suggestions of waiting for 30 secods. i still get nothing after waiting for over a minute.
what i do right now is use the built-in touch pad and keyboard of the macbook pro to get past the login screen. once i'm logged in, i can see that the bluetooth devices are not yet connected (the three dots that go across the bluetooth symbol at the top right of the screen are not yet there). then after a while, maybe about half a minute, the bluetooth keyboard and mouse are connected and i can use them normally.
it is not a big deal but it is very annoying.
i am using a logitech bluetooth mouse (v740) and an adesso bluetooth keyboard (wkb-4000bm). i also tried an azio bluetooth keyboard and had the same issue. all these keyboards are made for mac.
thannks in advance.

just a correction, the keyboard and mouse don't always automatically reconnect once i'm logged in. most of the time i have to go click the bluetooth icon at the top right of my screen, select the mouse and then select "connect". i have to do the same to the keyboard.
