T61 Laptop Keyboard Mouse Issue

Is the computer a desktop PC or a laptop/notebook?
are the keyboard and mouse both located on the same surface? Maybe you're pounding the keyboard , thus causing the mouse to move slightly. If that's not the cause, you can try replacing the battery in the mouse. If that doesn't fix it, try opening Control Panel/Device manager. In Device manager double-click on Mouse. Click on Driver tab. Click on Update driver. Alternatively, right-click on Mouse (in Device manager) and select Uninstall, yes, ok.
Restart the computer by holding down the Power on/off button for about 6 seconds. Wait 10 seconds then press the Power on/off button again to turn the computer on again. When it boots up it Windows will reinstall your mouse.
If you're using a touchpad go into Touchpad properties (usually located in Mouse in Control Panel). In Touchpad properties window you can adjust the sensitivity of the touchpad. On our Lenovo laptop, for example, the cursor would frequently jump, jitter, or otherwise move around when we were typing. Sometimes it would move slowly around even if we weren't typing. After adjusting the touchpad sensitivity in Touchpad properties window the cursor became much more stable, and it only moved slightly if I was really pounding on the keyboard.

Try ensuring that the touchpad hasn't been accidentally disabled (Hold down the '[fn]' key and press the F6 key on your keyboard to toggle the touchpad(mouse) to be enabled or disabled.

Have you tried using an external keyboard and mouse?

If the external keyboard and mouse work then we know it is something to do with the built in keyboard and touchpad on your laptop (likely - but not positively a hardware issue). If it does not work then we know that the issue is likely (but again not positively) software based.

You'll probably need to update your mouse & Keyboard drivers to Win7 compatible.

hi friend,
Erratic Mouse

1. The solution for an erratic mouse involves going into the registry on Windows. Backup your registry files. Never make changes to the registry without doing this. Go back into the registry. Go to the editor. Locate the key phrase that reads: hkcu---control panel---mouse. Delete this line from the registry. Close the registry editor. Shut down your laptop. Wait for 5 minutes. Reboot your laptop. Windows will create a new registry key for you. This should solve any erratic mouse problems.
Mouse Not Found on Laptop Boot Up
2. The laptop mouse is plugged in. You boot up your PC. The mouse isn't found. Chances are the mouse cable came slightly unplugged. Unplug the mouse. Re-plug the mouse into the laptop port. The laptop should recognize the mouse. Reboot the laptop if it is still not working after you check the cable.
Mouse Moving Slowly
3. A laptop mouse that is moving slowly is probably dirty. This type of equipment is prone to collecting dust and dirt. It's like a magnet for dirt. The solution is to clean the laptop mouse. Unplug the laptop mouse from the computer. Remove dirt particles from the optical mouse with a pair of tweezers. Make certain the eye area is clear. A small piece of debris can cause an optical mouse to move slowly. Remove the ball from the mouse, for a standard mouse. Wipe the ball with rubbing alcohol. Wipe the inside of the mouse with a dry cotton swab. Remove all debris and dirt. Replace the ball.
General Mouse Tips
4. Clean the work area where you will use your laptop mouse. This will reduce the amount of dirt that collects in the mouse.
   
   Work in areas that don't have high traffic for pets. Sitting with your pet cat or dog in your lap and using your laptop is not a good idea. The laptop mouse will attract and catch pet hair and dander, requiring you to clean it more frequently.
   
   Wash your hands prior to using your laptop or your laptop mouse. This will keep the equipment cleaner to make it last longer. Less maintenance will be required for both the laptop and the laptop mouse.

jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); }); instructions for sticky keyboard: Step 1 Soak up spills immediately after they occur. This not only reduces the risk of damage, it prevents much of the fluid from spreading beneath the keys. Use a towel, cloth or anything else you have handy at the moment.

Step 2 Unplug the keyboard from the computer or disconnect the power supply if you are using a laptop keyboard. Make certain nothing else is connected to the keyboard and unplug any USB devices.

Step 3 Pop the keys off your keyboard using a dull knife or flathead screwdriver. Do this slowly and carefully to avoid damaging the keys or the keyboard.

Step 4 Place the keys in a bowl full of warm soapy water, and let them soak for 20 to 30 minutes. Dish detergent is effective at removing dirt, oil and stickiness.

Step 5 Use a damp, lint-free cloth to wipe the large areas of the keyboard. A cotton swab can be used in smaller spaces and around the edge of the keyboard.

Step 6 Set the keyboard aside, upside down, on a towel and leave it to dry for several hours. This will also allow any trapped fluid inside the keyboard to drain out.

Step 7 Wash off any remaining dirt, oil or debris from the keys. Use a cotton swab to clean inside of each key, if necessary. Rinse the keys very well with warm water and set them on a towel to dry.

Step 8 Replace the keys once the keyboard and keys are fully dry. If your keyboard is still sticky, fluid likely leaked deep inside the keyboard. You can attempt to clean the internal part of the keyboard by yourself, but this will void the warranty and risk further damage. Either purchase a new keyboard or send yours to the manufacturer for repair.

jQuery('.article ol .image').each(function(i,e){ var $this = jQuery(this); $this.find('img').error(function(){ jQuery(this).remove(); $this.remove(); }); }); Tips & Warnings

• Using a can of pressurized air to clean your keyboard will remove any loose dirt and debris but will not get rid of stickiness or oil residue. Take a photo of your keyboard before removing the keys to make replacement easier.

Sound like you might have a virus - try running antivirus program - such as Avast or Antivir - which is free.
If that doesn't work, then try doing a System Restore - if that doesn't work, then do a System Recovery complete re-install - but back up your pictures and documents first as you will lose everything and you'll be starting over again fresh.

Try another keyboard and mouse then repost your findings. If it still does not work the ports on your system may be failing and you can try a usb keyboard and mouse

I've had this a work a number of times and it is usually a case of replacing the keyboard of the laptop. Its usually the pointing stick in the middle of the keyboard thats interfearing with your usual mouse motions. You can disable this usually by going in to the keyboard settings in control panel and disablign it in "pointing devices" This would resolve the issue without the need to replace the keyboard.

If your mouse is "locking" the two most likely causes are either due to a battery issue or a connection issue. The first is unlikely since you're saying it started just after you replaced the battery, but you might want to try again if you have other new batteries around that you can use. Also you could try Re-Pairing (if you have the bluetooth wireless keyboard/mouse combo that dell offers) the keyboard and mouse after reboot. step by step Instructions for re-pairing or fixing a corrupted are should be available on the Dell support website and vary depending on the exact model you have.

Assuming that your keyboard stops working when its on (same for mouse) then it means your machine will be frozen

1. Try to give it time (around 3 mins) without doing anything letting it resolve the issue the keyboard should work on later. If this solve your problem then your computer is just slow bcoz of a virus, too many programs to load at start up, new software or hardware update.
2. Try using a different keyboard when yopu boot up preferably a PS/2 keyboard,if this one works well then its means you nmeed to load new drivers for your keyboard and mouse
3. Also try running chkdsk to clear your harddrive for errors.
