    Laptop behaving very strange


    Since this morning, one of my laptops is behaving very strange.

    Symptoms:
    • Noticeable keyboard delay i.e. what's typed appears on screen with a delay. When typing, not all characters typed are shown. Example: last sentence (underlined) was before editing noll haracters typed ahown. It's not my bad typing, I know I typed every letter and space
    • Opened menus stay open only a few seconds, disappearing then
    • Focus changes constantly between active window and taskbar
    • Back and forward using thumb buttons in mouse work with 3 to 5 second delay

    That seems not so much but please believe me it makes this laptop very unpleasant to use at the moment.

    EDIT: I suspected a keylogger but Anti-MalwareBytes found nothing.

    Not very helpful, I know, but have you tried a system restore (my favorite generic tip)?

    Kari, are you using a wireless keyboard? I find that there are times when I experience the same thing and need to resync the wireless connection. I've also seen where it was necessary to change the USB port where the receiver is connected to the laptop.

    See, for example, Troubleshoot response failures in wireless keyboard or mouse

    @Jonathan, no I have not. Ran a full scan with MSE and Anti-MalwareBytes, found nothing, decided to give SuperAntispyware a change.

    @Corrine, yes. It's a Bluetooth set. I disconnected and paired it again.

    If I'm not going to find anything, I'm going to restore an image from last week. Thanks geeks for your tips.

    Hi Kari,

    Is it the same scenario when you boot in safe mode or as another user?

    If you can open Task manager, have a look at the processes running, maybe you can fidn a suspect process and kill it.

    Some other thoughts:

    - Is sticky keys enabled?
    - I wonder if the shortcut to change languages or keyboards has been tampered with. I think by default it's something like RIGHT ALT + P?
    - Have you done the big keyboard sweep on each key to ensure that nothing is stuck down?
    - Does the keyboard work in BIOS?
    - Have you tried to Re-install the drivers?

    I've seen a case where a bad battery was causing this issue. Try taking out your battery, then run on AC power alone.

    I wonder if it's something like this post on another logitech keyboard?

    Or this You Tube video from the same article.

    If it is then at least we know what the problem is.

    Why I am suspecting a keylogger or other malware is that keyboard works flawless both in BIOS and safe mode. Checked the video and post about Logitech Illuminated keyboard probs, nothing to do with my kb.

    I think I need to restore an earlier image.

    I'd restore too, it'll solve everything and will probably take less time than troubleshooting.

    If you want one last go at it try this UnHackMe - First BootWatch AntiRootkit from Greatis Software. The trial will should get rid of any malware of keyloggers if you have them and you can uninstall it afterwards (or re-image).

    Good luck mate.
