Kvm switch won't stay on second computer, switches back
Hello. I have had this KVM switch working for a few years now, although I did have some issues like what I'm going to describe at one point and they seemed to resolve themselves.
I just got a new pc computer and got everything set up again. When I click the kvm to go to my mac, it switches over and I can see the mac desktop. However, it only stays for about 3 seconds and then switches back again.
Also, I am randomly hearing the sound that I hear when I do switch over -- when I have not hit the kvm switch.

i have found that some graphics cards only allow for one monitor. at least that is how it was when i had an acer a few years ago, i currently have an area 51 m9750 which has a much better graphics card setup so it has the option for multiple external monitors...
search for WIN 7 & KVM switch issues... you will find thousand of hits, because WIN 7 has one unique feature where it disables internal and external ports if these are not in use.
In a KVM solution setup this would mean, while you are connected everything is fine, now when you switch over to your (Lets say) WIN XP and work for 30 minutes on it... and then switch back, WIN 7 might have already scanned and seen that the USB port where the KVM cable comes in is IDLE... so it disconnected it... you cannot get it back until you reboot your WIN 7 system. Its not the KVM solution is one of those Microsoft wonder weapons that breaks what has worked for 20 years
try to disconnect all of the KVM switch and
then try use one pc only and trace for the bad
and if all are the same then you must go to the
warranty center and ask for replacing the KVM
The switch may be the problem but it also may be the monitors internal power supply. To check you can open the case by the little switch and remove the plunger ( the little pin that moves up and down) If you get a picture back then the switch is the problem and you will have to bend the flat spring up to give it a little more movement. I would be if the monitor is about 2-3 years old that the problem is in the power supply board. After a few years many LCD monitors have issues with the power boards blowing capacitors. It happens on desktop monitors and rack mount units too. If you have an external power adapter for the monitor check the voltage output and replace if it is not steady. If the power supply is internal to the monitor then you will need to open the case and check the capacitors for heat damage. Check our site at: www.ccl-la.com/badcaps.htm for pictures of what to look for. Replace any that look like the pictures and you should be back going again. The values that you will need are going to be marked on the sides of the bad caps. Be sure to use a high temp replacement or the problem will be back in a month or two. If yo don't want to do the repair yourself we do offer a repair service of the monitor for $40 plus return shipping. If you have any questions just let me know.
I hope this helps, if so please rate our solution.
I have had the same problem off and on since I bought my Iogear 2-port kvm switch over a year ago. I have a DYNEX wired, multimedia, usb keyboard and a Dynex wired usb mouse. The operating system on my desktop is Windows XP, SP3 and on my laptop it's Windows XP professional.
Yesterday, my keyboard "died" on me about 8 times and each time it requires unplugging the keyboard usb cable from the switch and my laptop, rebooting, then plugging the usbs back in. Really, really frustrating and annoying. I'm not a techno guru, but I got to thinking that maybe the keyboard driver might be the culprit. I decided to go to Control Panel, clicked on Keyboard, then Hardware/Properties/Driver/Update Driver. I clicked on "update driver" and let it find one automatically. It took what seemed like a long time for it to find the driver but it found one. The device name changed to KeyMaestro P2360, the driver updated, and I noticed 2 additional files were added to the System 32 directory.
It's only been a day but so far so good. My keyboard hasn't failed yet since the keyboard driver update. I don't know if this is the solution for you or not, but it seems to be the one for me. I'll know for sure if I can through a few days without it failing again.
Typically, the KVM indicator light will only light up on the connection that is currently active. The indicator light will switch to another connection when that connection becomes active.
First I would make sure that all the mouse and keyboard connections are secure. I have seen where these sometimes pop out, and thus some componenty will not work. I would then make sure that all the computers are fully powered on. The KVM will not allow you to switch to a device if it is not powered on. The KVM may indicate that a connection is down by a blinking light if you switch to a port and the connection is not up. It sounds that you have atleast one good set of cables. I would confirm that the other sets of cables are good as well. Do this by swapping the other cables with the one port that you know you have working. Finally, with a set of good working cables, swap them over to the other ports on the KVM switch. Although it may be improbable, you may have a bad KVM.
AS always, I would review the product manual here:
