Dell touchpad stuck - DELL Inspiron 15 3520 Cnfg 2 Lptp 3Yr 2nd 2012

Anonymous,
The Error code that you have mentioned, 2C00:x21D, indicates that a 'Stuck Key' has been detected. The keyboard is continuously transmitting a scan code. The touchpad error might have come up because of the stuck key. You may have to replace the keyboard.
Thank You,

Disabling the touchpad on a Dell Inspiron can be useful when typing for long periods of time, or using an external mouse. Bumping or tapping the touchpad while typing can cause cursor jumping and unwanted results. Use the touchpad software to enable or disable touchpad controls. Download the driver for your touchpad at the Dell Support website.

Click on the "Touchpad" icon in the task bar. If the icon doesn't appear, you can download and install the driver for the touchpad from the Dell website, or choose "Start" and "Control Panel." Choose "Device Select" on the touchpad menu, or choose "Mouse" in the "Control Panel" menu and "Device Select." Click "Disable" under "Touchpad" to turn off the touchpad, or click "Disable Touchpad/Pointing Stick When a USB Mouse is Connected."

Is the right click button stuck down? Have you tried pressing it a few times to see if it will resume working?

Try an external mouse. You might have to turn off the touchpad in BIOS (F2 key on boot will get you into setup). Look for Mouse/Touchpad under 'Post Behavior' or perhaps elsewhere (differently displayed in various BIOS setups).

you are facing a defective mouse touchpad...have it repaired

well u need a flat screw and that usually will pop it off

u can try this all u can do is just go to this website and click on driver detective scan now and then click on the download now and then restart ur computer and then the touchpad should work and still if it doesnt work then uninstall and resintall the touchpad driver and the synaptic drivers and restart the computer and still if it doesnt work replace the touchpad from dell...the website is http://www.drivershq.com/Drivers/VistaDevices/Dell-Input-Dell-Touchpad-Pointing-Stick-Driver/13926/Drivers.aspx ................... thanks

Download and run the touchpad driver from support.dell.com. Go to drivers and downloads>enter your service tag or choose your model>choose your operating system and click the "Input device drivers" category and download the touchpad driver.

In the touchpad settings (Control Panel, Mouse) see if tap to click is enabled, if so uncheck and see if there is any difference. Also try booting in the safe mode, and see if that changes anything (F8 during boot to access safe mode) If no difference, then you'll likely need a new palmrest to fix the touchpad. If the touchpad works normally in the safe mode, try a new touchpad driver from support.dell.com
