Unlock windows box disappears after windows automatically locks the screen


I have a professional Windows XP Tablet from Lenovo X 200 ongoing execution machine. This problem does not occur * too * often, but enough to be annoying.

After 15 minutes of inactiviy, windows is the standard screen saver routine by locking the desktop computer. Meanwhile, the white box that says click on Ctrl-alt-del to enter your password is visible. There is also the virtual keyboard on the screen.

From time to time, I go back to my computer to see that white box unlock is missing! There is no way for me to go back to windows! I have literally remove the battery and restart. During this time, I lost all my unsaved data... not to mention that I keep not the most graceful way.

This happened to someone? What in the world could be the cause?

Thanks for the comments.

Hi Jim_B_NJ,

1. you have value to request password on Resume on the computer?

I suggest that scan you SFC on the computer that would be a system file corrupt on the computer search and replace.

The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows XP installation CD.

For more information please visit the link below.

Description of Windows XP and Windows Server 2003 System File Checker (Sfc.exe)


If you don't want to try windows to ask for the password after the recovery step turn it off below.

(a) make a right-click on an empty area on the desktop

(b) select Properties in the context menu that will open

(c) click the screensaver tab

(d) uncheck the box that says on Resume, password protect to disable.

(e) click OK

If you don't want the window Ctrl + Alt + Del on the logon screen, try the steps below.

(a) click Start, click run, type Control Userpasswords2, and then press ENTER.
Note The following dialog box may appear:
You must be a member of the Administrators group on this computer to open user accounts. You are logged in as username, and this account is not a member of the Administrators group.
In this condition, you must type the user name and password when you are prompted with the dialog box to type the user name and password of the administrator of the computer.

(b) click the Advanced tab.

(c) in the Secure logon section, click to clear the checkbox user must press Ctrl + Alt + Delete if you want to disable the CTRL + ALT + DELETE sequence

    A few days ago I left my laptop compaq so that Windows Vista Home Basic is open and maybe my baby cousins, touched, after returning a few minutes later, I found that Windows vista has been unable to work properly. Every time when I started the computer, after entering my password and log, Windows vista automatically locks the computer just in few seconds and asks me to connect it again. I type my password again, and then it opens and even once will lock automatically and asks me to log in again and again...

    I can't really understand what to do with it... I don't want to reinstall Windows vista, so it might be impossible for me... what I need to do? Hope to receive useful information for it...

    BTW, I did check the hard disk with BIOS, and it showed no errors on.

    Thanks in advance!

  • Update Windows automatically restarts the computer. I would like to disable this feature.

    Update Windows automatically restarts the computer. I would like to disable this feature. I'm running a machine business with complex projects requiring a configuration long and delicate. The details below:
    Type of operating system: Windows 7 Ultimate
    Problem: Status of the project lost after auto restart during the night
    Require: A method of disabling automatic restart after an automatic update is happening.
    Tried: I already tried looking in the registry for an appropriate key change, but no have been found appropriate.

    You can configure Windows update to meet your needs, for example, download the update and then let me choose when to install the same. This way you always get the automatic updates but you chose when and where and how to install updates at a time that is convenient.

    Then I suggest to change the Automatic Updates settings to meet the needs of PAHO.

    Choice, you can turn off to THE (not recommended), you can adjust to download updates only and allow you to install them at a convenient time, you can adjust information only, or you can leave to do what he likes.

    If you update, you must restart sometime in the case otherwise you are not protected and you might as well do not update at all. Everything is a matter of choice. One size does not fit all, so a choice can be made. I have updates informed me only, then I decide what, when and how to do to install the updates. It's my choice.

  • BlackBerry Smartphones how lock the screen during a call?

    Is it possible, a third-party application perhaps, to lock the screen on my Storm during a phone call? Sometimes I have to Secretary for a while and cradle of the phone on my shoulder. During these times, I either end up the person I'm talking inhibition or try to dial a number at random my contacts inadvertently. I've heard from a third-party application that is supposed to lock the screen during calls, and I'm willing to bend on this if someone can make me pointed in the right direction, however, I would like to know if there is a setting on the phone itself which can be manipulated to prevent face composition.

    In advance, thank you to all who replied.


    Absolutely, see TalkLock or StormLock to this end, both work very well.
