Wireless Mouse pointer
The mouse pointer is a device linked to the computer to control the position of the cursor on the screen.
A wireless mouse communicates with a receiver connected to the computer through a USB cable or a receiver in the computer. The receiver can also be a USB-dongle. This is a tiny USB receiver which is plugged in a USB port on the computer. Often a receiver or a USB dongle is included with a wireless mouse.
A wireless mouse requires batteries or rechargeable batteries for power.
When buying a wireless mouse pay attention to the energy consumption. In some mice the batteries last much longer than in others. Using rechargeable batteries in the mouse is much more environmentally friendly than using non-rechargeable ones. The difference is that a rechargeable battery uses 1.2 volts and non-rechargeable 1.5 volts. The mouse works fine on 1.2 volts. Sometimes the manual indicates that rechargeable batteries cannot be used while in practice it is quite possible. Try to use nickel-metal hydride (NiMH) rechargeable batteries because these have much less environmental impact than nickel-cadmium (NiCd) rechargeable batteries.
The lifetime of rechargeable batteries depends on the amperage. It is stated on the battery, for example 2000 mAh. The higher the number is, the longer the lifetime. Usually two batteries (AA or AAA) go in a wireless mouse. By using four batteries and a recharger you can always have 2 full batteries ready for use.
There are different types of wireless mice available. There are cordless mice that use a bluetooth connection or a WiFi connection. There also are wireless mice that do not work on batteries or rechargeable batteries but use a rechargeable capacitor. Make a choice between buying 'proven technology' or 'the latest technology'.
A wireless mouse has a switch. If the computer is idle the wireless mouse can be switched off so that no power is consumed.
Repair If a wireless mouse does not work, you may check whether the problem is in the mouse or the computer’s side. If the problem occurs in the mouse you can check whether the batteries contacts are clean and if there is enough charge left. Beyond that there is usually nothing that may be repaired in the mouse.
Disposal: Saving Resources
At the end of the mouse’s lifespan it must be disposed separately from other waste. The collection and disposal of these products are done by the supplier or municipality. Broken rechargeable batteries should be returned to the supplier or municipality as chemical waste.
