there's a good chance your firewall is doing this, you should open it, and look for a setting that allows you to open single ports..\n\nR3dm0

There (afaik) isn't a button which does so. If they're not working, i presume that something is faulty with your laptop.\n\nTry levering the keys out with a ruler or nail file, and checking if there is dust or dirt underneath them. Clean it out if so.

your key must be stuck...try shaking it or pressing it or something like that.

Make sure you're tapping (not holding down on) the DEL key the ENTIRE time of startup - don't wait too late.  Also, try a wired PS/2 keyboard if yours is wireless or USB.  Take a look at the resource below.

check the connections in the back of your computer, unplug it and then plug it back in, that should fix it.  If not I bet your keyboard is messed up, new ones are like $10 or less

Do a system restore to when it was working....\n\nAlso you can go to the device manager and pull the acpi compliant system this will reload all the drivers for every device on your system....\n\nIf that does not help hold the f10 key at start up and do a recovery if that does not work..\n\nCall 1-800-474-6836 and service the unit...

How long has this been going on?  Did you change anything or install any software prior to the problem surfacing?  Have you been surfing any warez sites?\n\nSomething is interfering with your keyboard.  You've done all the right things to date so I'd suggest that you look for something in the system itself.  Some process is messing things up.  When you hold down the shift key, the process eventually dies, releasing the keyboard for normal use.\n\nMy first inclination would be a keystroke logger or other spyware.  Install Spybot Search & Destroy and Windows Defender.  Update the defs and run a full scan with both products.  With luck, you'll find something and can remove it.

you need to get your keyboard replaced or your motherboard.  It's a short.  Call your manufacturer for more info to get it repaired.

The metals nodes in some keys are stuck. It may be defective. Have it checked thoroughly.

The keyboard on a laptop is not usually 101 keys. (They usually have about 88). You might want to check what the correct driver is for your keyboad and install it. If you boot it in Safe Mode it might work enough for you to fix it.

My take:  the keyboard is probably toast.\n\nCleaning it is worth a try, but I'd start checking into getting a new one.

You need to check if your internet is connected up properly, if so then check the services on .net messenger. this may be their problem in recognising your Key Port. if your internet is not connected up properly then you must either sort this out yourself or get your internet provider 2 check it out for you.

Try getting the buttons out (very very carefully), & clean the keyboard a bit. If that doesn't work, there's not much else you can do.\n\nAlternatively, you can use the 'Charachter Map' to type.\nTo get there go to ---> Start - Programs - Accessories - System Tools - Charachter Map

if it says that keyboard error then first check the that none of the keys on the keyboard is stuck to do that press all the keys one by one and then check. If it stil says the same thing them unplug all the devices from the back of CPU except keyboard, monitor and the mouse and then restart it. or if ur using USB keyboard then try a PS2 keyboard.

Try shutting down, unplugging the keyboard, plugging it back in, and restarting. If that doesn't work make sure your "scroll lock" key is not on. If that doesn't do it you probably have a fried keyboard.

I think u have pressed the Insert button in your keyboard. Just press the Insert button once more and then it will work properly.
