Frequent keyboard failure

I have had a problem with my keyboard not working since I switched to this KVM switch. It will work fine for a day or two, then suddenly only about 50% of the keys will work, mostly letter keys with the ctrl key taking on the function of the caps lock key, or the keyboard will not work at all. The mouse still works without any problem. I have tried hitting the reset switch and changing servers on the switch, but the only shutting down the server, then unplugging the cables from the box, then hitting the reset on the Black Box, then powering the server back up will fix the problem, only to have it reappear again within a few days. I am using Dell 2950 PowerEdge servers running Windows 2003 Server with service pack 2. Any suggestions are greatly appreciated.

Mac keyboard not working through SV211KDVI on windows

Chances are that the distance between the keyboard & the PC computer is attenuating the signal of the keyboard below the threshold (or level) required for interfacing with the PC computer.

Perhaps a shorter KVM cable between the KVM unit & the PC computer could be helpful.

Wireless keyboard and mouse works fine with computer but when I attempt to use it on the f1dh104l switch it does not recognize the mouse or keyboard. it is a dell e6400 laptop that i'm attempting to...

the problem is that most Wireless Keyboard and Mice combos use Composite USB, the KVM however is expecting one signal on each entry port (one for mouse, and one for Keyboard).

replace yoru wireless Combo for a standard Keyboard and Mouse to make this work.

A work around would be using a MS Wireless Mouse and a different brand of Wireless Keyboard using both Wireless receivers and plug them into different ports on the KVM

I just bought d-link kvm-221... switching two pc's in a single monitor is working fine but the problem is my keyboard and mouse are not working (didn't detect by kvm-221).

D-Link KVM's have a shortcut for "resetting" keyboard+mouse.

Hold down Scroll Lock and press M

If that does not help, try unplugging mouse and keyboard for 3 seconds then plugging them in again.

Keyboard not working on one side of switch

the GCS632U has keyboard and mouse emulation that may not function correctly with docking stations. To ensure the KVM it self is working correctly I would suggest plugging the single USB from the KVM directly into the laptop and see if you have the same keyboard problem. This will at least tell you if the KVM is working properly or not.

Belkin normally make very good KVM switches but they are pricey, cheaper ones can be picked up on Ebay, but not too sure of the quality

Repeated IOGear KVM switch failures

As a wild guess, it sounds like a static discharge MIGHT be affecting the switcher causing it to crash.

Try increasing your humidity to 40% and grounding yourself before touching the keyboard... This is the season for these static electricity problems... get nipped all the time and you MAY not even feel it to be enough to zap the switch.

Keybrd quits working on laptop after ctl-alt_del to reach login

Repeating keys? This is a common problem for KVM switches if you go beyond the devices' capability. As you can see, GCS62 is a PS/2 KVM switch and it was designed to work only using a regular PS/2 keyboard.

This KVM switch does not support PS/2 to USB adapter. It might work but it's not guaranteed to work correctly. This does not work properly if you have a docking station for the laptop. It might work for couple of months then it would stop.

You smay isolate the problem by following the steps below:

1. Connect the keyboard directly to the computer to see if you will get the same problem.

2. Power cycle the KVM switch by disconnecting it from the computers and leave it unplugged for a minute or two.

3. Avoid using hybrid connection (PS/2 converted to USB) only for testing purposes.

4. If that work, then you know the answer is that this KVM only designed an work correctly with native PS/2 connection.

Mouse and keyboard not recognized on second computer

Solution for the mouse. I have 8 KVM's. Most of my computers work with the KVMs. On 1 inland KVM the logitect and Microsoft optical mice do not work on one computer (but work with the other computers). They both are USB. I hook them up with a USB to PS2 adapter. If I use a ps2 ball mouse connected to the KVM the mouse works. All the Mice work if I directly connect them. Since I do not want a ball mouse I got a Frisby optical PS2 mouse. It works with all the computers on the KVM's.

I do not have a solution for the Keyboard yet. 1 computer (ASUS MB) on my trendnet or belkin 4 postion KVM does not recognize the keyboard.

KVM freeze, mouse and keyboard failure upon keypress

When ever trouble shooting a KVM that has a problem with one computer always swap the cables at the computer end -- that will tell you if you have a computer or KVM issue.

Can's switch without it switching back to first PC

Sadly, it is probably the KVM as this particular model has a string of failures and is only rated 2 out of 5 stars on Amazon due to poor performance. :( What I would do first is plug in Computer 2 directly to the monitor, keyboard and mouse with no KVM. If those work fine, it is probably not a computer issue; if you don't get video here, then it is a seperate issue with that PC. If Computer 2 is working, plug both computers into the KVM but switch the cables (plug Computer 1 into the KVM using Computer 2's cables). If Computer 2 shows up and can't switch to Computer 1, then it is the KVM messing up.
