Our guide to cleaning and maintaining your keyboardSPEAKING/WRITING PRACTICE SECTION 1. Find a funny picture of an input device and give comments. 2. Find the information on the topics and make a report:
1. The evolution of input devices. 2. Classification of input devices. 3. Early input devices.
3. Look through the text and make an instruction how to take care of any computer input device.
Computer Keyboards can get dirty very easily, to clean the surface of a keyboard is very straight forward. Shutdown your PC and remove the main plug, unplug the keyboard (remember where it was plugged in) and hold it upside down to release any debris from in-between the keys. This is where the patience comes in, make a note of the position of all the keys or you will have trouble putting them back correctly, alternatively just remove the letter keys A - Z from the keyboard (which is where the most of the dust/debris will be) and refer to fig. 2 as a reference to put them back. All the keys can be removed although the larger keys (space bar, enter key, shift keys, backspace, caps lock, etc) can be difficult to put back so you might avoid removing them. Remove the keys using the screwdriver, ease the screwdriver under the key and gently lift the key top off (see fig. 1). Note: don't forget to make a note of their position!! When you have removed all the keys (except any keys you wish to avoid) use the compressed air (or vacuum cleaner) to remove any dust and debris from inside the keyboard.
keyboard), give the surface of the keyboard a good wipe over ensuring to clean as much as possible any keys that you haven't removed. When the keyboard is nice and clean replace the keys
4. Make an advertisement for a real or imaginary input computer device.
