BATTERY CHARGING AND REPLACEMENT:

One must charge one’s laptop battery to keep it operational.

Procedures:

 Plug the laptop battery charger into the wall socket.

 Put on the wall socket to start charging.

 Never you over charge the battery. Once the battery is fully charged, disconnect it from charging unit (that is unplugging it).

NOTE:

 There is no need to fully drain your laptop battery every time you use it. It does not take longer time to recharge the battery.

 Nowadays laptop/computer batteries are made with lithium ion and it is the lightest of all the metals.

 Lithium ion is not harmful on the environment.

 It is the most technologically advanced battery, but unfortunately with time you will need to replace the laptop battery after some years.

What is Preventive maintenance or preventative or scheduled? Is a maintenance that is regularly performed on a piece of equipment to lessen the likelihood of its failing. It is performed while the equipment is still working so that it does not breakdown unexpectedly.

In practice, in a preventive maintenance schedule may include things such as

 Cleaning

 Lubrication

 Oil changing

 Adjustments

Corrective maintenance is where equipment is repaired after wear, malfunction or breakdown. Corrective maintenance is a task. Performed to resolve equipment failure and restore it to operational condition. This type of maintenance is the most commonly used approach and it occurs when routine check-ups fall through the cracks, leading to major mechanical problems. MRO items (maintenance, repair, operations items) are materials and products that companies buy for maintenance and carrying out repairs.

What is the relationship between corrective maintenance and preventive maintenance?

 For preventive maintenance, when planned well, can comprehensively reduce the overall maintenance cost and increase the productivity of equipment and facilities while

 Corrective maintenance is usually performed after the occurrence of a malfunction or failure in equipment.
