Question about D-Link KVM-221 (DHKVM221) 2-port KVM Switch

Open Question

Acts like a stuck key

Intermittently while typing one key will "stick". Usually the 'Y' key. It is random in nature and doesn't happen at regular intervals. I am using an HP USB keyboard and a Dell USB mouse. I checked the connections for both usb devices and they are ok. This is really annoying as I will use the backspace key and will delete the previous 2 sentences if I am not careful.

    I have the exact same problem with a Microsoft Ergonomic 4000 running through a D-Link KVM-221. It's totally random; I can't nail down any pattern for when it occurs. It's most noticeable when in Outlook and the delete key sticks, deleting every message in the inbox. :(

    I have the exact same problem with any random key sticking. I had replaced the IO Gear KVM because it got fried somehow so I decided to use the D-Link KV221. I have a Logitech wireless keyboard/mouse combination MX700. Every so often a key will get stuck and stay on and if I am not careful when I delete an email in my inbox it will start deleting all emails. It is definitely random in nature to no specific key or to any program because I have the same issue with Outlook, Excel, Word and my contact manger. It is definitely the D-Link switch because I never had a problem with my IO gear KVM switch. If you know how to solve this issue I’d love to hear about it.

SOURCE: using KVM-121 with 2 monitors

You should be able to -- the KVM switch would just switch inputs for the monitor, but since your two monitors would be plugged in directly to your computers, the switch wouldn't actually be affecting your monitor inputs.

Just make sure to plug your monitors directly to your computers and not use the switch.

SOURCE: Hi, Is it possible to use

As it stands on its own, no. You would need either a USB adapter to match either the keyboard or mouse port on the KVM. Another solution might possibly to get USB Hub to attach. Without physically testing it myself, I am not sure if it would work, but it is possible.

Hi, my acer aspire 4930's keyboard not functioning correctly.. when i press letter "a" it appear as "A1" same as "Q" appears "Q1".. pls help me


Hi.

Try cleaning the keyboard with a clean, dry paintbrush just in case there is anything stuck under the keys. Once you have cleaned the keyboard try typing keys to see if it does the same thing. If the keys type as normal then you have resolved the problem.
If the keys still type other characters along with the letter then there is a strong possibility that the keyboard needs to be replaced.
This usually happens when something has been spilt on the keyboard causing it to type random characters or the characters directly above or below them.

Seeing as the keyboard is a laptop keyboard you can use a wireles/wired keyboard or you can use the on-screen keyboard if you can't get the keyboard to work.


If there is anything else please post back.



Good luck.

My Logitech keyboard worked perfectly last week, but when I came back from my friend (I had my keyboard there, for the third time) it didn't work perfectly after 1 day, it started typing randomly but when...


When my logtch does that is usally is a stuck key. It can also be a low battery or the antenna is too close or too far away.

Most of the time its a stuck key. turn it upside down and knock on it like you are knocking on a door. that usually will jar the keey loose. you may be able to find the stuck key by pushing on them and see which one doesn;t pop back or feel right. Don;t try to pry it loose do the knock.

If the battery has just enough power left you can get some wired things happening but usually it just stops working.

Move the antenna so that it is about a foot away and is clear line of sigt from the keyboard to the antenna. You may want to reset or reconnect using the button on the antenna and the bottom of the keyboard.

9 out of 10 times its a stuck key.

Bios continous beep, repeated ////, intermittent touchpad issue


The beeping when powering on is from the keyboard buffer being filled up by a stuck key. Same thing in windows. Best bet is to just replace it as it is pretty cheap.

Here is a link for one for $25

Non-functioning keys toshiba equium keyboard m40x 149


Have you tried connecting a regular desktop keyboard to your laptop? If so, does the same thing happen?

Keyboards do develop problems, and can usually be fixed by replacing the keyboard. It's not necessarily a virus (actually highly unlikely).

Channel switches on it's own


This is probably a sticking button, similar IR signal from another remote control, or simply a short on the system board that holds the controls.  A simple cleaning might take care of this.
