Retrieving original admin password from sleep mode

Just set up my computer running OS X, put the computer to sleep and either I typed my password incorrectly originally or I forgot my password. How do I reset or retrieve my password?

Everytime when i retrieve my Mac Pro from sleep mode, it doesn't respond,screen goes blank, and on front bottom side white light indicating sleep modes keeps on blinking, I have to press power key turn it off and then start again.

Even some times it starts, but it takes long time.

TS1819 Mac OS X 10.7.4. How do I configure my network settings so I don't have to enter the password to my wireless router every time I start up or come back from sleep mode?

When I first got my MacBook Pro my wireless network at home (Linksys Wireless Router) popped right up and I entered the password and had no problems automatically connected after that. I went to a friends house this weekend who also has a wireless router named Linksys, obviously with a different password. Ever since I connected to her network I have to enter my network password at home everytime I start my computer up or wake it up from sleep mode.
My questions is what caused this to happen and how do I reconfigure my network settings so that I don't have to re-enter my password all the time?
Thanks

My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero

My zero Key isn't working after waking from sleep mode. This is a real problem for me because my password contains a zero. I don't recall spilling anything or jamming it just that it worked before I closed the computer and wasn't after I woke it up.
I would like to fix the key but if that's not possible right away , Is there a way to reset my password without being able to type with a key thats in it?

Start by swapping the keyboard. You don't need to spend a fortune, and handy to have spare. USB cables can be bad even new.
When I had some problems Apple wanted to blame the mouse, keyboard, cable, but in the end I found
A. run Disk Warrior
B. Corrupt pref or conflict with version of Hardware Monitor and other background tasks

My password works fine when I turn the computer on, but when I try to wake it from sleep mode the computer doesn't recognize my password -- the same one I used successfully when I turned the computer on.

Okay, I seem to have solved the problem I posted about earlier. I noticed that the language preference in the upper right hand corner of the screen (between the date and time and the Spotlight icon) had somehow gotten switched from American English to French. When I switched it back to American English, my password worked when waking the computer from sleep mode. I have no idea why changing the language preference would affect the way the password works but that seems to have been the case. I'll post again if I experience more problems.

T440s display won't wake up from password-protected sleep mode

The display on my new T440s stays off and cannot be recovered, when it is in password-protected sleep mode (or when it has gone to sleep from password-protected screen saver mode). The only way to recover is to press the power button to shut down completely, and reboot the computer.
When I remove the password protection from sleep mode, the display turns on and off as expected during sleep/wake cycles.
Have any of you experienced this? Is there a fix? I do want to use password protection in sleep mode for security.
Thanks.

I posted this yesterday on another Mac site and thought I'd post it here, too, since my experience is similar to rmckillen's, and BobThe Developer has an explanation for it (thanks!). I've had my 15" MacBook Pro for almost 3 months, and it's been working fine until now. Tonight after it went to sleep while open, I tried to wake it up and the screen stayed dark, though you could faintly see what was on it. When I tried pressing the power button, I could see through the darkness that I was getting the usual message asking if I wanted to shut down. I waited for the approximately 2 minutes for that to happen, and then the machine appeared to shut down for a few seconds--only then the dark screen with faintly visible image of what was really there appeared again. I tried closing the machine and opening it again, but that didn't help, nor did clicking the mouse. The only thing that worked was forcing a quit by pressing command-control-power all at once. The machine shut down, and then when I turned it on again, everything was back to normal. My question now is, should I bring my machine in to Apple about this--will it be something they can fix, or is it just a problem I'll have to live with (or will the next operating system address it?)? Thanks...

Resetting admin password from non-original CD

We have a 400 Mhz Powerbook G3 running Mac OS X 10.3.3. We got it from eBay as is––no CD's, no other information. Now that I have inadvertently locked System Preferences, that is a problem because we do not know the admin password.
I see that you can reset the password by booting up from a Mac OS install disc. My question is, would it be possible to do that using the OS X install disc for v. 10.3.7 that came with my iBook G4?

Usually the OEM install disc that comes with a particular computer model will not work with other models. However, you can give it a try. If you can get it to boot the Powerbook, then after the installer loads select Reset Admin Password from the File menu.

When my IMac awakes from sleep mode, the password login screen freezes and no cursor appears.

Hello! When my IMac awakens from sleep mode, my log in screen is frozen (I can't type anything) and there is no cursor.
I can turn the computer off and on again and then I have an active log in screen, but if I walk away from the computer and it goes into sleep mode and i have the same problem trying to bring it back from sleep mode.
Thoughts?

Hey Kristogirl,
I understand that when waking from sleep mode, your iMac freezes. Try executing these two troubleshooting steps:

Everytime I wake up my computer from Sleep Mode the sound starts to crackle on my X-Fi?

BT Keyboard Loses Connection When Waking from Sleep Mode

I'm running Windows 7 on a late 2009 27" iMac and my Bluetooth keyboard keeps loses connection when I wake my computer from sleep mode. Usually the only way I can get it back is my resetting. Anyone know of a way to fix this? Any help would be great appreciated.

If the MBP doesn't wake when you open the lid but does when you press any key afterward, do this:
Applications > Utilities > Terminal
Copy and paste the following text in the Terminal window:
*sudo pmset lidwake 1*
You'll be asked for your admin password. Type that in (Note: the password will not be displayed as you do so). Press Return, and quit the Terminal. Close the MBP, wait for it to sleep, and open it again. Does it wake now?
If you want to change it back so the system doesn't wake when you open the lid, repeat the procedure, but this time type or paste:
*sudo pmset lidwake 0*

Satellite P200D-11R sound and graphics crash after waking up from sleep mode

Hi,
I am wondering if anyone here has had similar experiences to mine (below) or can offer any solutions.
I have upgraded my P200D-11R OS to Vista 64 Ultimate to take advantage of the extra performance. I also add that the BIOS has already been updated to version 1.4.
Well, everything works fine with the standard 2Gig of RAM which the laptop was supplied with originally, however, when I upgrade the RAM to 4Gig (2 x 2GB Samsung 667mHz modules), sound and graphics problems appear every time the machine is brought back from sleep mode.
The sound card makes a very laud fuzzy noise every time it wants to play a sound and the graphics produce lots of horizontal lines on the screen. I then just have to restart the machine which means loosing all my unsaved work.
Everything works fine as long as the machine does not enter sleep mode. I have currently disabled the sleep mode to prevent the machine from entering it but I am finding life very hard without it.
I am very surprised and also disappointed at the fact that Toshiba did not test these machines with Vista 64 Ultimate and 4Gig of RAM!
Extra info:
The memory is the same Samsung type as the 1Gig modules supplied by Toshiba originally with the machine, and the part number Toshiba recommends.
I have tried installing other (more recent) device drivers by Realtek and ATI without any improvements.
The memory modules pass all tests and are not defective. They have also been tested on my friends Dell notebook with no problems even in sleep mode.
I have installed my friends Dell 2Gig memory modules in my P200D and they too produce exactly the same results with post-sleep crashes.
My thoughts are that this must be another BIOS issue unless anyone can shed some light on the issue from another angle.
Please help! Many thanks in advance.

Hi Sascha
Since you are running a Vista 32bit version, the upper limit of the memory recocnised by the machine is 3.2gb which is the maximum a 32bit operating system can address and use. The diffrence here is that I also upgraded my OS to Vista Ultimate 64bit to get yet better performance out of the 64bit dual AMD processor.
3.2gb of RAM on 32bit OS does not necessarily increase the performance. However, it keeps the performance stable when you open many more programs at the same time since the machine has more RAM to play with before staring to use the much slower hard drive as operating memory (Page File), to keep all thoes open programs running.
A 64bit OS such as Vista Ultimate 64, recognises the whole 4gb of RAM and much more (for instance, 8gb with 2 x 4gb RAM modules). The 64bit OS itself would generally consume more RAM to start with, however, with 4gb I found the general performance to be much better. Going back to the problem however, my P200D-11R with Ultimate 64 and 4gb RAM refuses to wake up from sleep mode gracefully and the graphics and sound crash every time, forcing me to restart.
My feelings at present is that eventhough your machine may be slightly different, I bet if you upgrade your OS to 64bit, the machine will start recognising all of the 4gb of RAM and post-sleep crashes will start to appear!

When trying to log back from sleep mode, the screen behaves as a rotating cube, with the mouse pointer in the top left corner. Hangs.

When the computer in woken from sleep mode we see two login options (bineg used by two users).
But when we try to login, the screen just behaves as a sluggish rotating cube.
Nothing works, we just have to hard boot at this time.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Can't use mouse/keyboard/trackpad when waking iMac from sleep mode

Basically as the title says. When I wake my iMac from sleep mode I am unable to use my keyboard/trackpad/mouse during the login window. Once the screen goes black by itself, after a minute or so I can then log in properly.
Yes the keyboard/mouse/trackpad are all connected when it wakes from sleep as I can use any of them to wake it from sleep, I just can't move them or type with them in the login window.

IMac with waking up randomly from sleep mode

Hello everybody!
Since I installed Snow Leopard (all updates done) my iMac is randomly waking up from sleep mode without any reason that I know of. Some days everything is fine, next day it wakes up when I am at work and retrieves mails (thats how I see it is awake).
Also I set it up to shut down after 1h idle time- this does not work as well.
Any ideas how to track the problem?

My MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode

Hello, everyone. Since I updated to Yosemite, my MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode.
Does anyone know how to fix that?
Thanks in advance,
Arthur.

Hi, arthurpacifico.
Thank you for visiting Apple Support Communities.
Here are a couple troubleshooting steps that I would recommend trying to see if it corrects this issue.
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
Reset your computer’s PRAM
http://support.apple.com/kb/HT1379
If the issue persists, try the troubleshooting steps I have attached below.
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.Restart your computer.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.
