Analysis of the problem of electric power in notebook and its practical tips

Heat dissipation

On the surface, the heat of the Notebook and the power of the notebook has no connection, in fact, the relationship between the two is very close. Notebook due to small size, the natural flow of air dependence is almost impossible, so many of the use of heat pipes and other cooling technology, but when the temperature is too high, the notebook will also start the built-in cooling fan to help dissipate heat. Due to the use of the notebook is a temperature-controlled fan, only when the temperature reaches a certain program will start, so as long as we can help the notebook cooling, control the temperature of the notebook, you can reduce the time to start the temperature control fan, so you can extend the use of time notebook. Use the notebook as much as possible in a well-ventilated place, pay attention not to let sundries plug the notebook's cooling hole, if it is in the home and office use, conditional friends can prepare a water cushion (that is, the kind of pouring into the liquid mat, the average person in the summer sitting on the cooler), and then put the notebook on the water mat to use, Since the water has a good thermal conductivity, can fully absorb the heat generated by the notebook, so that the notebook kept at a lower temperature.

　　CPU Operating Frequency

In the notebook to make some mobile CPU and general desktop CPU is very different, the mobile version of the CPU frequency is generally not fixed, it will be the CPU requirements to change the CPU's working frequency, of course, the higher the work frequency will be more cost electricity, So in the notebook as far as possible do not run on the CPU requirements of higher software, so that the CPU can control the frequency of work to a certain extent, to achieve the purpose of saving electricity.

　　Setting up power management

The Power management program can be set up in the Windows Control Panel, and we can generally set it to portable/laptop type. At the same time, I suggest that you can in the display properties of the screen saver directly set to "black screen", and the wait time set to 5 minutes, so that when we do not operate the notebook for a period of time, will be directly to the black screen state, this is more than running other screen saver program to save

For some famous manufacturers of notebooks, usually provide some more professional power management software, in conjunction with their respective notebooks, often have some special features: such as Sony's dedicated power management program can set the speed of the cooling fan, You can also turn off unused IEEE1394 interfaces and memory stick slots to save electricity; IBM's power Management program can reduce the refresh rate of the LCD screen; The Toshiba Toshiba Power Management Program can directly shut down any device you specify without power. Reasonable use of these software can further extend the use of notebook time.

　　Hard disk

For a notebook hard drive, it is the power consumption of the parts, as long as the power consumption in the read and write state, the more access to the hard disk, the more power of the hard disk, so do not normally run large software on the hard disk, and do not use the battery to defragment the disk. Conditional users can appropriately increase the physical memory of notebooks, reduce the use of virtual memory system, in the case of using WIN98 system, if the physical memory reaches 256MB, you can completely disable virtual memory, which is also a good way to save electricity. In addition, we can also set the hard drive to stop working time, in order to let the hard disk in the appropriate time to enter a stop state, please pay attention to this time according to the use of their own notebook hard disk to set reasonable, if the time to turn off the hard disk is too short, the hard drive may be frequent start and stop, this will affect the life of hard disk.

　　Drive

Notebook CD-ROM is also a large power consumption in the notebook, the full speed of the CD-ROM drive than the hard drive more charge, but also will produce greater heat, so when we do not use the disc in a long time it is best to remove the CD ROM from the optical drive. Because most of the notebook is 20 times times the speed of the Low-speed optical drive, generally do not recommend the use of optical drive spin down software, so as to avoid the speed of reading disk has caused too much impact. For frequently used discs, the best way is to use virtual CD-ROM software to virtual to the hard disk, this is the most power-saving method.

　　External devices

The general notebook will have a lot of peripherals to use, but please note that these peripherals as long as the connection to the notebook, even if it does not work will consume laptop power, so when we do not need to use these peripherals, it is best to take them off the laptop. There are some ports of the notebook such as print port, COM port, etc., when not working will also consume notebook power, if you do not use these ports, preferably in the BIOS to disable it. If your laptop also has an infrared port and a wireless card, you can turn it off when you're not using it. Many friends in the use of notebooks like the use of external mouse, out of the need to save electricity, it is best to use the notebook with the mouse, even if you want to use an external mouse, I suggest that we do not use a photoelectric mouse, because it is more than the ordinary mice to charge electricity.

　Software

When you select the software that is running on your notebook, we do not have to use some full-featured but very high system requirements of software, we can also choose some of the same functionality but the system requires lower software, for example, we only need to do a simple typing work, do not need to use Office XP, its function, although powerful, However, the requirements of the system resources are also higher, we can use the lower version of the OFFICE2000 even windows with the WordPad and Notepad to achieve the same goal, which can greatly reduce the use of CPU and hard disk, but also a good way to save electricity.
