[RESOLVED] Laptop - No cttrl+Alt+Delete

[stanav]

Hi guys,
I have a laptop that somehow the keyboard combination ctrl+alt+del on the built-in keyboard doesn't work anymore. When I say it doesn't work, I mean not just in Windows but also in DOS (booting from a bootable floppy diskette). However, ctrl+alt+del will work on an external keyboard (PS/2 or USB). I already replaced the built-in keyboard with a new one (thinking the old keyboard is bad) but it didn't fix it.
Is there anything else I can check/test before comdemming it's the motherboard that need to be replaced?

PS: except for the ctr+alt+del combination, all other keys seem to work OK on the built-in keyboard.

Maybe one of the keys is broken on the laptop?

Click on the Letter C and then scroll down to Control Alt Delete and see if any of the listed suggestions help.

Yeah, I thought that too. That was why I replaced the keyboard, but the new keyboard didn't make any difference.

Thanks for the link, Hack. It contains lots of useful tips. However, I could not find anything that can apply to this particular case I'm having. The Ctrl+Alt+Del key combination doesn't work event when I boot into DOS using a floppy. You know, normally, when in DOS, at the A:> prompt, if we hit ctrl+alt+del it will restart the computer. However, it does nothing on this computer. If I keep on doing it many time or just holding the keys down, I start hearing beeps... That means that they keys actually do something, but I just don't get the desired response...

Then I think your orginial assumption is reasonably accurate. It would seem the keyboard, at least in this case, is not communicating with the motherboard.

there is an alternate keypress that does the same thing in windows. ctrl-shift-esc.

Yes, you're almost right, only if I can sign on to Windows. The signon screen where it says "Please press Control + Alt + Del to sign on to Windows" won't take ctrl+shift+esc as an alternative though.

I strongly believe something is wrong with the motherboard, so I will replace it. Will mark this thread as resolved. Thanks you everyone.

you can turn the control alt del requirement off. its in control panel -> users. "change the way users sign on and off". Hook up the external keyboard and get into windows and then remove the requirement.

This computer is part of a domain, I'm afraid that Windows will not let me change the way users sign on.
Thanks for the suggestion anyway.
