Dell laptops feature a row of hot keys, which are configured to quick-launch an Internet browser, frequently used programs or control speaker from the press of a button. While these hot keys are convenient, many Dell owners find them annoying; the slightest bump to a hot key can accidentally launch a program at the wrong time. If you rarely use hot keys or you find them troublesome, you can turn them off. Disabling Dell hot keys is not permanent; if you want to use hot keys in the future, you can reconfigure your computer to restore the feature.
Right-click on the desktop and select “Properties” from the shortcut menu to open the “Display Properties” dialogue box.
Press the “Settings” tab in the “Display Properties” dialogue box and click the “Advanced” button.
Select the “Intel Graphics Technology” tab to open the Dell configuration page.
Click “Hot Keys” and check the “Enable Hot Keys” check box to disable the hot-key feature and click the “OK” button.
