M30: BIOS password: never set but now asking for a password
I've never set my BIOS password before on my Toshiba Satellite M30 laptop.
However i have just switched it on, and the laptop is asking me for a password.
Does anyone know why this is so?
I am not asking on how to hack it - but just wondering what the hell is going on!
Hi Daniel,
The BIOS password(s) are stored on the CMOS chip itself, and the normal procedure for resetting them (if the password is not known) is to fully reset the CMOS chip contents.
Although this sounds pretty straight-forward the problem is that the password information is stored in a non-volatile part of the chip so that the normal BIOS reset techniques do not affect it. Techniques such as disconnecting the CMOS battery in order to remove all user information will also not work.
ASPs use a special device for resetting the CMOS chip contents although some repairers will opt to change the mainboard where they do not have the necessary equipment available.
regards,

Installing Photoshop CS4 from original Disk onto my new Macbook Pro. Serial number accepted but now asks for the serial number of a previous version e.g. CS3 which I no longer keep. How do I resolve ?
Tina Hadley did you migrate/transfer your applications over to your new Macintosh? If so this could cause problems with your serial number being recognized. Please run the available uninstallers located in Applications/Utilities/Adobe Installers folder. Once this is done you will also want to run the CC Cleaner Tool. Details on the use of the CC Cleaner Tool can be found at Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6 - http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html.

Help. I just got a new iPad 2 and set up sync with iCloud and no password. Now asking for a password and I never set one up. What password does it want: iTunes, iPhone (no real password there either). Tried as many passwords as I could think with the iPad locking me out since I don't have the password! Would like to use the iPad but can't get on to try it.
Thanks.
DesparateSo I guess it will only be new apps that I download that are allowed to give me their updates while 13 updates wait for me on an ID I can no longer access.
Yes... sorry.
In the future, if need be, you can re download your purchases for free > Downloading past purchases from the App Store, iBookstore, and iTunes Store
Good rule of thumb is to back up your purchases regardless > Mac App Store: Backing up your app purchases -
I turned my ipad off. It's now asking for a passcode. Is that the same as the password for my Apple ID. I used it but it still will not let me get access,

You will need to restore your device as New to remove a Restrictions passcode. Go through the normal process to restore your device, but when you see the options to restore as New or from a backup, be sure to choose New.
You can restore from a backup if you have one from BEFORE you set the restrictions passcode.

My MacBook is now asking for a password. When I login, it loops to a blue screen, and back to the login. Incorrect logins create a shaking of the login screen. I tried restarting with the shift key depressed, with no luck.
I performed a hard shutdown, and upon start I could access my system without logging on. I'm not sure what caused the issue, but I have not booted up in almost a week.

HELP! my mac has logged me out and now asking for a name and password?
I was logged on shopping on top-shop online and suddenly the mac shut down.
It seems it has reset its self! My icon has disappeared and its now asking for a name and password.
i have tried my log in but it is not working.
Is there another way to reset the password?
can i reset it to log back in what can i do?
I have rebooted the computer several times but i dont know what to do!First, make sure caps lock is not on.
Another reason why your password might not be recognized is that the keyboard layout (input source) has been switched without your realizing it. At the login screen, you can cycle through the available layouts by pressing the key combination command-space or command-option-space. See this support article.
If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
Otherwise*, start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. In the window that opens, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
▹ Restart
from the menu bar.
You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
*Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions. -

I want to set up my Apple ID for my phone but it ask for the Gift Card but I dont use them ? what do I do ?
If you are trying to create an Apple ID without using a credit card, you have to follow the directions in the article you were reading (http://support.apple.com/kb/HT2534) exactly. Note that you have to start by downloading and installing any free app, then create the ID. You shouldn't be asked for a Gift Card to create the ID.

I added a custom ringtone . Then later I tried to add another three set but now after sync . Am not able to get rid of the first one... It's still there as my custom ringtone. But my iPhone in iTunes shows all four... But the phone shows only one...?
Paul--you are a life-saver!! Worked great. I did have to look around to make sure I was getting 4.9 instead of 4.7 (even when the file was named 4.9 at techspot.com), but I finally got the right file, did the install as you suggested, and everything is now fine. One note, though, that I haven't seen mentioned in any of this thread: when I first tried to open up iTunes after getting back to 4.9, the following message appeared: "The file iTunes Library.itl cannot be read because it was created by a newer version of iTunes." I merely went to the old .itl file that was created when I did the update to iTunes 5, renamed it, moved it over to my now new 4.9, and iTunes opened fine. My library was a few days out of date, because of the few days' lag from the time I did the iTunes update, but that was easily taken care of, and everything's now working fine. Thanks again!!!

i was charged for a movie that never was downloaded, i asked for it but the conection was too slow and I never was able to have the movie that i asked for...how can i get it without being charged again, who could remove the chage from my Crecit card?
You may not be able to get a refund, since the terms of sale for the iTunes Store state that all sales are final. You can contact the iTunes Store, explain the reason for your request, and ask, though:
http://www.apple.com/support/itunes/contact.html
It's possible they'll make an exception for you, particularly if the problem was on their end preventing the movie from downloading in a reasonable time.
Good luck. -
Student account for Adobe CC - downloaded and worked but only for TRIAL - now asks for license - how do I access the programs? I was given a redemption code (apparently redeemed already). How do I get the licensing code?
Ask whom/wherever you got the redemption code from for one that has not already been used.

On my iphone 5 i have two iTunes ID, one is no longer in use, but keeps asking for a password which I no longer have, whilst the other is still being used. How do I delete the old ID?
Hello steveod2
The main thing to do is to sign out all services on your iPhone, like iCloud, iTunes & App Store, iMessage and FaceTIme. Check out the article below for more information.
