Logitech K400 Keyboard Not Working In Windows 7?
Nov 5, 2012
i have logitech k400 wireless keyboard with touchpad. it works fine in bios and in xp but on some reason it does not work in win 7.it detected the device when i plugin the small wireless device and says "ready to use" but nothing is happening. keys are not working, touchpad is not working, mouse buttons are not working (touchpad buttons).there is no driver cd that came with the keyboard it is plug n play.it worked almost instantly in xp, 1-2 seconds and worked.my main keyboard is saitek cyborg v7. if you think it conflicts, then earlier i used a mini wireless keyboard with touchpad and it worked fine under Windows 7.somewhere on logitech site i read that someone had similar issue and that he said it worked in safe mode because some program was blocking it?@! i have not tested in safe mode but something tells me it will work either way i dont care about safe mode. i know keyboard is fully working and i need it with my Windows 7 machine.

I've run into an old problem when trying to reinstall windows 7, when I put the CD in and alter the BIOS to boot from CD, I get to the screen saying "Press any key to boot from CD" or something like that.
I've got a logitech G15 keyboard and a Microsoft media keyboard, both are USB, when I press them there is no response and it boots from the harddisk. I've had this problem ever since I installed Windows XP, first I thought it was a keyboard issue, but then I got the G15 and the problem persisted.
Since then I've replaced the motherboard, PSU, infact I think I've changed every single component, but the problem persist. Anyone have an idea of what is causing this? I'm forced to dig into the old storage at work for old PS/2 keyboards every time I'm installing a new OS
PS: The keyboards both work perfectly in BIOS, after booting an OS and when the installation disk has booted. Just in that place in between where you need to press buttons to either boot from various media or skip disk checks etc.

have just had to deal with 2 lappies of mine getting the Blue Screen, now neither one will work, so here I am with a "new" hard drive with Windows 7 32 bit and I'm wanting to throw it through the window in front of me.I am using an IOGear Bluetooth adapter and I keep getting the message that a device wants to connect "click here to allow" so I do, now they want a pairing code. Does anyone here know if there is such a beast that will work so I can get on with solving the REST OF MY WINDOWS 7/STARTING OVER problems, of which there are numerous ones.ould be so very grateful if I could just get off of this lappie keyboard, which is extremely uncomfortable, not user friendly and I won't last much longer with it

Causing me to unplug it and plug it back in again. It happens mostly when it's been idle for some time.
I'm guessing it's something to do with the power management? Also maybe a recent update has upset some setting or something...
Got a list of Vaio updates to attend to but I'm not sure if I want any of them? The thing works so only win 7 updates

I've not found much information while conducting a search here on LogiTech Drivers. From what I understand LogiTech isn't creating drivers for Windows 7 Beta, should I just use the Vista versions despite getting a Compatiability Message?

My brand new Logitech G510 keyboard won't wake my PC up from sleep mode. My mouse (Razor DeathAdder) will wake up PC from sleep mode. When it does wake from sleep mode I hear the beeps like new hardware has been found and then I can use my keyboard. I've checked for the latest firmware and software from Logitech's website, but it's a fiasco looking for updated drivers and firmware on their site.

as described I use a Logitech G510 keyboard with multimedia keys and the posibility to insert a headset into it (the keyboard got its own soundcard). The keyboard also got a volume wheel which worked with Vista like it should: I could controle the speaker's volume by the keyboard.
Now with Win 7 I can't use the wheel anymore, even with the latest drivers.
My system:
OS Win 7 professional 32 bit
Intel core duo E4500 2,2 GHz; 2GB RAM
Sapphire HD5770 graphiccard

On my home built system, when booting up, if I don't have this generic Dell usb keyboard hooked up, I can not choose from multiple drives I have installed with the Logitech G510 keyboard( which I use to choose, I just have to have this other keyboard connected). Other than that, it behaves normally, fine.Is there something I can do in the way of getting a driver onto a usb thumb drive and then keep that thumb drive permanently attached (like inside the case)?

I have the Logitech x520 speakers and Windows 7 x64. Since I've installed the new os, my 5.1 has not been working. Just the main front left and right speakers work, plus the sub. Under the configuration, it is set to 5.1, and when I run a test, all speakers make the test noise. I then thought it was iTunes, but doesn't seem like it. How come my speakers test correctly, but when I play music, only two +sub work?

I can't get Setpoint to install and without installing it my mouse (MX400) some times laggs on a click. It's strange, sometimes it will work fine then all of the sudden, when I click something it 'sticks' for about 1-2 secs. Any ideas?

So yesterday I bought these quadrophonic speakers from a friend. The problem is, that only front right is working (everywhere- in test, windows sound, music, games etc.)... I thought that the other speakers might be bad, switched them but no- now when the FR speaker is the different one, it is still working and the others are not... I plugged the green wire in the green socket, the black one (rear) in the black socket, confirmed it in the realtek manager (front speakers, rear speakers)... I tried setting it to other mods (5.1, 7.1), it�s the same, only front right speaker is working... I downloaded the newest driver (2.52 or whats the newest one) both from gigabyte and realtek...When I plug the green wire in my notebook headphones socket, both speakers work ok (I have Windows 7 ultimate on my notebook to, but the sound card is not realtek hd)...

installed the R/C last night. When it finally was done installing doing an upgrade from 32-bit vista to windows 7, the final reset loads up and i cannot use either my mouse or keyboard. I have tried pluggng them into every usb slot i have, restarted with both plugged in and not plugged in.tried the 2 other mice and another keyboad. One being a microsoft keyboard that. The keyboard does work when choosing between the different loadup options, but still doesn't work in safemode.When i try to reinstall either Vista with my bootup cd or with the copy of windows xp i have, it starts the loadup , but keeps getting the blue screen before the install even starts.

Keyboard and mouse not working in Windows 7 (desktop), even in safe mode. The keyboard does work in the BIOS. I have tried to attach a PS2 keyboard, but it doesn't work either. I can't get to the device manager to check drivers.

I have an issue with my USB keyboard and mouse combo (and the issue seems to apply to any USB mouse or keyboard). They have stopped working on my PC (windows 7 self built PC). They don't even function to enter the BIOS. I recently upgraded my PC with a new motherboard (Gigabyte), CPU and RAM. After the install everything was working fine. I was using a USB connected controller that controlled both a wireless mouse and a wireless keyboard. This combo set worked fine for a few days after the installation. Suddenly (for no reason I can figure out) the USB mouse and keyboard stopped working. I have an old keyboard that connects via PS2 connector and it works fine. I have a mouse that has a USB connector and it doesn't work. Other USB devices pull power from these same USB ports with no issue. I'm able to charge my Kindle, my Andriod cell, my Sansa MP3 player and it will recougnize USB thumb drives with no issues at all. When I plug in the USB mouse I notice that the light on the mouse will come on at first but dies and windows gives me a message saying that it failed to recougnize the device and then that it failed to load drivers. I've been told to check the Legacy USB support setting in the bios and I have. I've enabled and disabled the setting a number of times with no difference.

I have a Toshiba A300-18A laptop, bought in Portugal in 2008. It came pre-installed with Vista and I always left it in place because I couldn't find a proper time to backup everything properly. These holidays, I finally had the time to do that and 2 or 3 weeks ago I installed Win7. I didn't do an upgrade and did the custom install over the previous Vista version. Right after installation, during the first uses, my keyboard froze during an internet session. Simply, no key would work, but I had full control of the computer otherwise. Over the next days I found it happened quite frequently, and it didn't even need to be on internet. The most often place to freeze is in text editors (ConText, TexnicCenter), Excel (I'm using Office 2007), an online MMO and even the login screen, before I can actually access my computer. A restart usually solves the problem temporarily, sometimes I need two restarts in a row.Due to this, I did a reinstall of Win7, this time formatting the C: partition where I was making the installation. So this was a real clean install and I still had the same problems. I thought it would be drivers, so I installed some drivers I downloaded from Toshiba support center and THEN I found out about Toshiba's Win7 installation.Still the same problems. There are more curious things about the keyboard: it usually seems to think ctrl is pressed. I have opened the on-screen keyboard and noticed the ctrl-key depressed. Unpressing this key, thought, does not rehabilitate the keyboard. This ctrl-press must not always be on, thought, because sometimes I notice parallel behaviours and other times I don't. For example, I don't get 'save file' dialogs if I press 'S', but I do see the screen zooming in and out in a web browser if I roll my mouse-wheel. Also, I have some defects in Office (namely Excel) that I think may be related, and this since my first install: sometimes I'm going to Open Excel or Word and it says I have the ctrl key pressed and asks if I want to go through. More commonly I don't get this warning, but inside Excel, the usual shortcuts ctrl-c ctrl-v, ctrl-o (new book, portuguese version) offer me the insert/delete rows dialog. Sometimes ctrl-ins has this behaviour too, other times it works fine while ctrl-c does not. It's all very random.Finally, to complete the problems described in the subject. I've also noticed a behavious I NEVER had before installing Win7. Most often while playing the MMO (but not exclusively there) my screen goes white with some activity going up and down (sort of a mis-tuned TV from the analogical days) and I can only bring it to place changing windows to get my normal desktop. The MMO runs in dedicated full-screen mode and I guess it must be changing resolution. Also frequently (about 40% of the times), when I boot my computer it shows up the wrong resolution (1024x768) and, in the login screen, the little button on the bottom-right that allows one to shut down and restart shows up only these two options when ordinarily it shows 4 to 6 options. During normal use, I often get the video-going-white problem when I tilt the laptop display up and down.In 3 years I never had one single of the symptoms with Vista, now I get them everyday. Problem is that I quite enjoyed Win7 (and I don't like Vista) so I'd like to keep this OS if possible.

I have HP Probook 4535s wich came originaly with SUSE Linux. Yesterday I changed OS to Windows 7 Professional x64 (I got all drivers from hp oficial web) but still I have this message: " Keyboard filter 01 is not installed". I tried with Windows Update, but nothing. What I noticed is that I dont have anymore scrolling function on the right side of touch panel. I have HD webcam and all new drivers and picture is not so good like before (with Linux). Do I have some solution or I have to back Linux ?

The typical -go to control panel and keyboard language setting- instructions dont work on Home Premium 7 for some unknown reason. The OS seems to be in English, but the keyboard doesnt want to change to Spanish.
Recent reinstall from partition. Legit copy, came with the laptop. Was working before the reinstall OK. Iirc the default interface might have been showing spanish, which might explain why i didnt have this problem before in the keyboard.
I think I was given the option to choose language at reinstall, and that I chose English. But everyone else who-s had problems with interface language never complained about keyboard issues.

I've come across an interesting problem recently which I have tried to solve to no avail. I installed Windows 8 Developer Preview on a separate hard drive to my base Windows 7 install, and had an issue that arose where the OS suddenly decided that the drivers the keyboard was using were invalid. This is not the (current) problem, however it is important to mention. Now, to fix the Win 8 driver problem I went to the device manager, uninstalled the drivers, and then unplugged/plugged the keyboard back in. Since that rather bodged fix, the keyboard suddenly stopped working in Windows 7. It shows up in device manager as working, and I can set macros in the associated Razer software, although it does not perform its most basic function of typing. I have tried a similar tactic to that which I employed while fixing the problem with Windows 8, although my attempts have been fruitless. The keyboard in question is a Razer Lycosa, and the OS is Windows 7 Ultimate, 64 bit.

I bought a SSD, installed it, installed Windows 7 Ultimate. Got into windows and everything was fantastic. Installed all the windows updates, video card drivers, ect... Then rebooted the computer and lo and behold, it doesn't recognize the SSD as a valid boot device anymore. Assuming that the install corrupted somehow, I decided to run startup repair on the Windows 7 disk. However once the disk gets past "Windows is loading files" all the lights on my mouse and keyboard shut off and they stop working. However up until that point they work fine, if I go into BIOS they work no problem. I have no idea what the issue is... I literally JUST used this same disk to install windows 7 and had no issues less than 30 minutes ago... The only advice I've been able to find thus far has been to ensure that legacy USB settings are enabled, and they are. Also, if I boot into windows on a different drive that has the OS installed my mouse and keyboard work just fine in windows as well. As it stands now I cannot fix my windows install or even reinstall windows...However up until that point they work fine, if I go into BIOS they work no problem. I have no idea what the issue is..

The laptop I'm working on (And HP G series; running Windows 7 64bit Home Premium) had a NASTY trojan that disabled the keyboard and mouse (is what I'm assuming). I was able to work on the laptop with a USB mouse and the onscreen keyboardAfter going through about 10 AV software I finally got rid of all the Trojans (the scans on various AV software ran clean multiple times after removal); but the keyboard and trackpad continue to be disabled.Under the Device Manager it lists as the device as a "code 10" error.Doing some Googling I found a post that said do delete the registry entries that were labeled "UpperFilters" and "LowerFilters"; which I did and I rebooted.Now my USB mouse OR my USB keyboard won't work.I tried using a Linux Live CD and the trackpad and keyboard DOES work there no problem. Also the keyboard works fine when I'm in the BIOS.It's only when I'm in Windows (even in Safe Mode) that the keyboard/trackpad/USB Mouse/USB Keyboard doesn't work...so it's not a hardware problem.Things I've tried (besides deleting those registry entries)- Startup Repair- sfc /scannow- Reinstall the drivers (when I DID have access to Keyboard and Mouse)So to recap; I cannot use the keyboard/trackpad (or a USB Mouse and USB Keyboard) in Windows (including safe mode); but they DO work when not using Windows.
