How to set up energy conservation

Desktop using alternating current, the majority of energy-saving features of the computer may not be very great importance, but it needs to use battery-powered laptop computer, the use of energy-saving features should be taken seriously. How to design computer hardware more energy-saving, this is not a user problem to be solved. Users can do on the computer is set up on the efficient use of energy-saving options.

Energy-saving two set-conditioning needs of users: First, the computer's BIOS setup program on energy-saving way in the set; most important thing is that the Windows 98 operating system, such as many energy-saving settings and operation. Computer systems in the practical implementation of it, Windows system should take precedence over energy-saving settings in the CMOS settings.

1. BIOS settings in the energy-saving

In the CMOS settings, has a large "Power Savings", which can choose to "Maximum laptop Battery Life" and "Maximum Performance" and other options. "Maximum Battery Life" is the default mode of energy-saving settings. The notebook has several energy-saving mode, such as Idle Mode idle mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. The
notebook computer settings, have been able to regulate power consumption, mainly in energy-saving computer into the state, the timely closure of some of the equipment without the use of the system. If the state of waiting, turn off the display and hard drive; into the dormant state, in addition to the closure of the display and hard drive, memory can also save the contents of your hard disk, the entire computer system shut down to maintain the basic state, once activated, or restart the computer, desktop Will return to the precise state of dormancy before. In the energy-saving settings in the CMOS, mainly set up by Idle Mode to enter Standby Mode of the Standby Timeout time set by the Standby Mode to enter Suspend Mode of Suspend Timeout. Notebook computers use most of the Phoenix BIOS. Various energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.

2. Windows of energy-saving settings

For the average user, in the Windows system for the management of energy-saving operation may have a better understanding of some simple. Windows help file, "the management of hardware and software" entries, two laptop computers and energy-related content: "Energy Management" and "the use of portable machine," "management on the laptop power supply." Energy-saving settings in Windows, you should read it.

In the Windows "Control Panel", click "power management", will be able to open the "power management attributes" dialog box. As shown in Figure 1, "Power Management Properties" dialog box, should "use of power" set to "Portable / laptop" and reasonable arrangement "to wait for the system" and "turn off monitors," " The closure of the hard disk "option. Different computers can have some options to manipulate the differences in the new factory-to-date computer and the software will be more workable option, the details should be set up in accordance with its own computer functions and help files for Windows.

If the need to completely run out of notebook battery power, do not look for other ways to discharge anything, only the "power management attributes" dialog box will be the "power scheme" is set to "always open" and will "wait for the system" and "shut down Monitors "and other options set to" never ", but also allows the computer automatically calculate a number of complex 3D demo program, which will soon be able to use the remaining dry battery power, of course, when these do not forget to dispose of Unplug the AC plug.

Charging techniques

A number of lithium batteries is equipped with notebook computers, such as the use of the wisdom of the SBS battery technology, accurate measurement of battery life, so to use up some of the worry. The use of nickel-metal hydride batteries should be careful not to over-charge frequently, or else they will reduce the battery life, so to very good control of the charging time.

Ni-MH battery charge in the pre-discharge should be in charge should be fully recharged, the use of methods and the use of mobile phones and pay attention to issues of Ni-MH battery is the same. Bought a new nickel-metal hydride battery cell phone, require the completion of three fully charged and discharged after a normal start to use it, the laptop battery should also be the case.

Most users accustomed to the use of each notebook computer, plug the AC power supply, with very little battery power for laptops. In fact, at least a month should be used to power batteries once or twice, the battery will be fully used up, followed on a one-time full of alternating current. Remember this one:
rechargeable batteries, dry full charge, useful and friendly, just do it a little trouble.

When the need to replace notebook batteries, preferably with a selection of models to replace the battery. However, if the old computer is to use nickel-metal hydride batteries, in order for longer battery-powered, of course, can also be specified by the computer user's manual or manufacturer's recommended selection of models of lithium batteries.

The use of laptop batteries and energy-saving skills

Look at popular science books as a child, learned through training in mice with the roller cage in one direction on North Korea to carry out running for the next generation to provide electricity, very strange. But the idea of the industry and the latest ideas, it is necessary to the far less. In order to get laptop power supply to support a longer period of time, the industry invented a patented technology: the keyboard charger.

Keyboard charger

The charger is a key concept: a magnet assembly in a number of keys on the keyboard, power button mounted on a coil seat, tapping the keyboard when the user when the magnet coils in the campaign, resulting in induced current, the current through into later To come to the battery charge. It is said that those gathered by tapping the energy of the keyboard, battery life can be increased by 20%. To be playing a joke, the proposal in its notebook computer casings on the coat light bulbs, power failure or Zouye Lu day when beating the keyboard to lighting, is really called "flashlight."

Energy-saving notebook is a request

Not long ago, playing one of the old 386 laptop, which does not drive, multi-media did not, of course, can not keep up with current notebook fun, but one thing I feel deeply that the battery seems to be very durable. Although there is no computer is now 386 strong computer 3D and multimedia features, but from the word-processing needs of the energy point of view, it is much more energy. In all fairness, the notebook is really not as easy to use desktop, the reason why we use the notebook computers, because we lack a fixed quietly sitting in one place of business conditions, so we have to move office, so we are not the notebook computers for the completion of the What 3D design and video production, not what is used to playing three-dimensional simulation of the game, all the basic word processing, data and Internet use, such as office and therefore may not need the latest CPU and strong 3D accelerator card, it is necessary to know that these two components in the Desktop are in need of cooling fans, that is to say they are energy-hungry. If you care about battery time-keeping, you buy the laptops when they should take these factors into account.

Nickel-metal hydride batteries and lithium batteries

At present, the major notebook computer batteries using both: Ni-MH battery and lithium batteries. Since there are two types of cells exist in the market, of course, also have their advantages and disadvantages. The most obvious one, that is, we buy cell phones when they have made very clear that the Ni-MH battery cheaper than lithium batteries, its negative side is the relative size and weight of larger. Lithium batteries with these characteristics is just the opposite. As the user like lighter, thinner, longer battery maintenance of the notebook computer, so lithium batteries subject to the pursuit of more high-end products favored by the user.
