- Do not use the CD drive frequently when the Laptop is in battery power.
- It is better to optimize the power option through the control panel option. Select maximum battery for maximum effect.
- It is very important to reduce the programs running in the back ground when the Laptop is in battery power as they run at boot up and increase the CPU load and battery consumption.
- De-fragmentation of the hard drive regularly is very helpful in making it faster. This increases the efficiency of the hard drive and decreases the power consumption.
- Do not keep the charged battery for long time without using it. If once charged, it should be used at least once every two to three weeks.
- Use the Dim mode in its lowest range to reduce the brightness of the screen. This considerably reduces the power consumption. If the CPU Fan control is available, reduce it to minimum.
- The heat vent is placed on the sides and back side of the laptop. So it is very important to place the Laptop in a well ventilated place during use. As a result, Laptop runs smoothly.
- Clean the air vents with a cloth or keyboard cleaner.
- Deactivate the programmes that are running automatically, when the Laptop is running on battery.
- It is better to reduce the number of external devices connected to the battery when using in battery power. For example, USB devices, WiFi etc. These devices are powered by the Laptop and use more battery power.
- Avoid playing games and playing a DVD in battery power.
- Increasing the RAM of the Laptop by adding an additional RAM is one of the very useful things. It allows the laptop to process more and fast rather than relying on virtual memory. Virtual memory increases the hard drive use and increases the power consumption. But the use of additional RAM will increases the power consumption slightly, so use only if memory intensive programmes are used.
- Do not store much data especially Audio and Video files in the Desktop since it is running in C drive. Save data in other drives.
- Reduce the use of Graphic in the Laptop while running in battery. Graphic and Video cards use much power similar to the Hard drive.
- Clean the drives to remove unnecessary files using the Disk cleaner option in the Performance and Maintenance of the Control panel.
- Always keep the battery contacts clean. Inspect the battery atleast once in a month. If the contacts are dirty, clean it with sand paper or file.
- Hibernate the Laptop when not in use so that, it can be run very quickly and avoids the boot up.
- Do only one thing at a time when the Laptop is running in battery. For example avoid combining the job of Typing and browsing. Stop all other programmes and do only one at a time.
- Stop the auto save option of Word and Excel while running the Laptop in battery. Since the auto save is working at regular intervals, it increases the hard drive activity and increases the power consumption.
- Another important point to be remembered is that we have to choose best Laptops with good features to increase the laptop battery life time.
- Switch off the wireless card if you are not interested to access your network or internet.
- Reduce the volume level or mute it.
- Disabling the Bluetooth option helps in getting more life to our laptop battery.
- Disable the unused ports and components like VGA, Ethernet, PCMCIA, USB, etc. while the laptop is running on the battery.
- It is better to stop the work if the laptop runs on very less charging battery. Otherwise it may be damaged.
- Do not try to work on the laptop continuously for too long.
- Be careful when charging your battery. Never hook it up to charge it when you’re not around.
These tips are important precautions to be taken to increase the life time of laptop batteries.

Physics is a diverse area of study and in order to make sense of it scientists have been forced to focus their attention on one or two smaller areas of the discipline. This allows them to become experts in that narrow field, without getting bogged down in the sheer volume of knowledge that exists regarding the natural world. Below is a list – by no comprehensive – of different disciplines of physics.
- Acoustics – the study of sound & sound waves
- Astronomy – the study of space
- Astrophysics – the study of the physical properties of objects in space
- Atomic Physics – the study of atoms, specifically the electron properties of the atom
- Biophysics – the study of physics in living systems
- Chaos – the study of systems with strong sensitivity to initial conditions, so a slight change at the beginning quickly become major changes in the system
- Chemical Physics – the study of physics in chemical systems
- Computational Physics – the application of numerical methods to solve physical problems for which a quantitative theory already exists
- Cosmology – the study of the universe as a whole, including its origins and evolution
- Cryophysics / Cryogenics / Low Temperature Physics – the study of physical properties in low temperature situations, far below the freezing point of water
- Crystallography – the study of crystals and crystalline structures
- Electromagnetism – the study of electrical and magnetic fields, which are two aspects of the same phenomenon
- Electronics – the study of the flow of electrons, generally in a circuit
- Fluid Dynamics / Fluid Mechanics – the study of the physical properties of “fluids,” specifically defined in this case to be liquids and gases
- Geophysics – the study of the physical properties of the Earth
- High Energy Physics – the study of physics in extremely high energy systems, generally within particle physics
- High Pressure Physics – the study of physics in extremely high pressure systems, generally related to fluid dynamics
- Laser Physics – the study of the physical properties of lasers
- Mathematical Physics – applying mathematically rigorous methods to solving problems within physics
- Mechanics – the study of the motion of bodies in a frame of reference
- Meteorology / Weather Physics – the physics of the weather
- Molecular Physics – the study of physical properties of molecules
- Nanotechnology – the science of building circuits and machines from single molecules and atoms
- Nuclear Physics – the study of the physical properties of the atomic nucleus
- Optics / Light Physics – the study of the physical properties of light
- Particle Physics – the study of fundamental particles and the forces of their interaction
- Plasma Physics – the study of matter in the plasma phase
- Quantum Electrodynamics – the study of how electrons and photons interact at the quantum mechanical level
- Quantum Mechanics / Quantum Physics – the study of science where the smallest discrete values, or quanta, of matter and energy become relevant
- Quantum Optics – the application of quantum physics to light
- Quantum Field Theory – the application of quantum physics to fields, including the fundamental forces of the universe
- Quantum Gravity – the application of quantum physics to gravity and unification of gravity with the other fundamental particle interactions
- Relativity – the study of systems displaying the properties of Einstein’s theory of relativity, which generally involves moving at speeds very close to the speed of light
- Statistical Mechanics – the study of large systems by statistically expanding the knowledge of smaller systems
- String Theory / Superstring Theory – the study of the theory that all fundamental particles are vibrations of one-dimensional strings of energy, in a higher-dimensional universe
- Thermodynamics – the physics of heat
It should become obvious that there is some overlap. For example, the difference between astronomy, astrophysics, and cosmology can be virtually meaningless at times to everyone, that is, except the astronomers, astrophysicists, and cosmologists, who can take the distinctions very seriously.
N.U.P.A, in liaison with the patron, N.U.P.A(Mr. Mjomba) and the chairman, Physics Department (Prof. Mwabora), is inviting all the Physics students from all levels of study for a special students meeting to be held at the department.
