    No kbd or mouse (WinXP and Logitech)

    This is a Dell system with a wireless Logitech mouse and keyboard. All MS updates have been applied. A few days ago there was a notification that Logitech had new updates. These were downloaded and installed. Now, the mouse and keyboard do not work. When the system starts, the mouse cursor is in the middle of the screen. Neither kbd or mouse respond. I have tried the following actions: replacing the batteries and resynchronizing the receiver unit. All lights seem to indicate contact. If I try to start the system in Safe Mode, at that point the keyboard works (F8) and I can select Safe Mode. As the startup proceeds, the system gets as far as loading the AGP driver and then hangs. I have not tried booting into the command line only mode. I have also tried using a wired mouse, but no luck there either. Is there a way to start the system from a cd, go to the hard disk, and remove the Logitech software? Or are there other methods to get into the system so that I can try a Restore Point? Any other suggestions?

    If you haven't successfully logged in since making this change then you should be able to use F8 to start with the "Last known good" configuration.

    That was one of my ideas as well. However, as the user has no password, the system continues to boot right on through to the desktop. A couple of programs that are run at startup start, but without kbd or mouse, I can't even kill them.

    The F8 key must be pressed almost as soon as the system starts to boot. On Dell systems, there is an initial splash screen where you are offered the F8 or F12 (I believe) options. Press F8 then or simply continue to tap the F8 key as the system is starting.

    Re: No kbd or mouse (WinXP and Logitech)

    Thanks for thinking along. When I press F8, the Menu comes up offering various modes of operation. I can move the cursor with the kbd to select Safe Mode, and then press Enter. The system now starts going through its various checks of the hard disk partitions, and then it starts to load the various drivers or whatever it needs in order to get into Safe Mode. But at a certain point, it just hangs and never continues on to successfully start in Safe Mode. I am beginning to think that the only way to repair this type of problem is by using the recovery cd from Dell and hoping that it will offer an option to simply repair an existing installation.

    Have you tried contacting Logitech ?? If it was their download that borked the system they might be aware of it by now and have an answer or at least a suggestion. You might also try contacting Dell support to see if they have any suggestions. I'd use the recovery CD as a last option

    Re: No kbd or mouse (WinXP and Logitech)

    Logitech said they'd never heard of this problem, and tried to blame it on a firewall or antivirus program. I do not accept the firewall possibility, that is not logical. The AV program could have had a negative effect, that sometimes has been known to happen. If that is the case, and the drivers or dll's for the kbd and mouse are blown, what are my options then to repair or replace them?

    Always somebody elses fault, eh ?? If you can't get it to boot up I'm not sure how to proceed. I'll have a look around and see what I can come up with.

    Re: No kbd or mouse (WinXP and Logitech)

    But what happens if (as Stuart has suggested) you select "Last Known Good Configuration" rather than "Safe Mode"?

    Re: No kbd or mouse (WinXP and Logitech)

    If I select Last Known Good Configuration, I get exactly the same results - the desktop will eventually show up, mouse is centered, startup programs run, and absolutely no response from kbd or mouse. Last Known Good configuration is useful if you have got hardware driver problems, or something that wouldn't let you get to the password login screen. Once you have entered your password (if there is one) LKGC considers this to be a successful boot. And that is again part of the problem. The system will boot, it appears to be able to see the wireless receiver so it thinks that a mouse and kbd are attached, but they just do not work. And I find the system hang situation when going into Safe Mode also quite unusual. Any ideas on what the difference is between the boot process of Safe Mode and Command Prompt only? Who uses what mouse/kbd driver software at what point in time?

    Re: No kbd or mouse (WinXP and Logitech)

    I don't have any new ideas at the moment, I will keep thinking.

    I had never before realised that significant disadvantage of allowing Windows to automatically log in without a password being required. It certainly will make the Last Known Good option much less useful, as you will only be able to use it if the system really can't startup, rather than if you can't log in.

    Re: No kbd or mouse (WinXP and Logitech)

    Does the PC have a PS2 socket that you could connect a different keyboard to? Or could you try connecting a USB keyboard? It is possible to do most Windows things without a mouse if you know the appropriate shortcuts.

    Re: No kbd or mouse (WinXP and Logitech)

    Possibly the system hang when booting to Safe Mode is keyboard related. As you know, in Safe Mode, Windows loads only the bare minimum of drivers. It's probably loading a keyboard driver, but since you are using a wireless keyboard, would it be possible that the system thinks that there is no keyboard attached? Have you tried booting to Safe Mode with a regular keyboard? If that works, you would be able to navigate through the Start Menu (with the keyboard) and perform a System Restore to a point prior to the new Logitech drivers installation.

    Maury,
    Does your Dell have a floppy drive? Do you have a boot floppy?
    Do you ( or a friend ) have a boot CD available?

    Either of these should give you access to a CMD prompt, where you can try to remove the Logitech drivers manually and plug in a wired type mouse and keyboard temporarily.

    Re: No kbd or mouse (WinXP and Logitech)

    Thanks for all of the useful suggestions. What I have tried so far was to use a standard PS2 mouse, but that didn't work. This might possibly be related to the fact that the Logitech keyboard was still attached, I am not sure. My next step, probably Sunday, will be to try both PS2 mouse/kbd and then USB mouse/kbd. Once I get one or the other working, then I can figure out the rest. As for booting from floppy, the hard disk is NTFS, so a Win98 or DOS floppy won't help. If I could find a way to boot into NTFS from CD, then I still need to know which files might best be deleted (or renamed) to prevent them from loading until I can get regular functionality.

    In all my years of working on computers, this is truly a unique problem, and I am determined to solve it properly without having to start all over, and to learn more about this startup procedure. If this can happen to me, it can happen to others and the solution may very well be worth it's weight in gold.
