Various types of laptop batteries
One of the tricks: how to properly use and maintain the battery of the notebook. The battery is the key to affecting laptop standby time. To improve battery life, it is essential to pay attention to battery maintenance.
1. Carefully read the battery maintenance section of the manual before using the notebook;
2. When charging for the first time, you should charge the battery continuously for 12 hours, and fully charge and discharge 3 times in a cycle to completely wake up the new battery;
3. If you use an external power supply for a long time, it is best to remove the battery. Many friends have not noticed this problem. When the external power supply is used, the battery is not removed, which not only affects the battery life, but also makes the heat dissipation burden of the notebook computer heavier and shortens the life of the notebook computer.
4. Regular charge and discharge. Even a lithium-ion battery that has no memory effect has a certain inert effect. If it is not used for a long time, it will deactivate the lithium ion and need to be reactivated. Therefore, if you do not use the computer for a long time (3 weeks or longer) or find that the battery charge and discharge time becomes shorter, the battery should be fully discharged and then recharged. Generally, it should be fully charged and discharged at least once a month.
5. It is best to turn off the laptop when charging, so that the battery can be fully charged. Do not unplug the power supply during charging. Shutdown charging will shorten the charging time by more than 30% compared to the startup charging, and it can extend the battery life. It is best to use it after 30 minutes of charging.
6. Prevent exposure, prevent moisture, prevent chemical liquid erosion, and avoid short-circuiting of battery contacts and metal objects.
The charge and discharge times of a lithium battery are generally not more than 800 times, and each time it is charged, it shortens the life of one time. It is recommended that you use an external power supply as much as possible. If you need to plug in and unplug the power supply several times, and the built-in battery of the notebook computer is not pulled out, the battery life will be greatly increased, because each time the external power supply is connected, it is equivalent to charging the battery once.
The trick is to optimize the power management options. For laptop users, we recommend using the Windows XP operating system. Of course, if the configuration of the laptop is too low or even meets the minimum configuration requirements of Windows XP, then it is another matter. Reasons In addition to the rich features of Windows XP, the more important thing is that Windows XP's power management for laptops is the most advanced of all computer operating systems. If that works with the Centrino platform, of course it is better - as below As shown in Figure 1, the 1.4 GHz Pentium-M only operates at frequencies below 600 MHz when the load is small.
If your laptop supports Intel SpeedStep, AMD PowerNow or Transmeta's LongRun technology, it is important to remember to install the latest drivers to get the most out of it. WindowsXP is automatic, Win2000 is set as shown below, you can Find a balance between performance and power consumption according to your requirements.
1. Do not use a screen saver
2. Select “Portable/Pocket†in the power usage plan. The following times are set according to your needs. The situation of each person is different. Of course, there is no hard and fast rule. Generally, the time to turn off the hard disk is set. Slightly longer than the standby time, so as not to affect the life of the hard disk.
3. Enter “Advanced†in the “Power Options†property, and use the “Power Button†reasonably, which can bring you great convenience. Reasonable use can also improve the battery life (see the figure below). For example, setting "When you close the portable computer" to "Standby", when you leave the laptop for a while, it saves power and can greatly protect the confidentiality of private data, and does not need to wait for the restart time.
For laptops that use first-tier manufacturers (such as IBM, SONY, HP, Toshiba, etc.), they usually provide some better power management software and have some special features: IBM's power management program can reduce the refresh of the LCD screen. Rate; TOSHIBA Toshiba's power management program can directly shut down any device you specify in case of insufficient power; SONY's dedicated power management program can set the operating speed of the cooling fan, and can also turn off the unused IEEE1394 interface and MEMORY STICK Slots to achieve power savings. Reasonable use of the unique technology of these different manufacturers can also extend the battery life of the notebook.
A city bicycle,[1] European city bike (ECB) or simply city-bike, is a bicycle designed for frequent short, moderately paced rides through relatively flat urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday riding in normal clothes in a variety of weather conditions.
Generally as they are more suitable for urban environments, they focus more on comfort and practicality instead of speed or efficiency. They normally have a slightly curved, roughly planar aligned and elevated handlebar, providing users a straight sitting position. They have fewer gears and they often are heavier than road bicycles. They might have the top central frame bar diagonally aligned for allowing easy mounting in and out and they might have a back or front frame for transport of items. The saddle is typically larger compared with other bicycles and the majority is provided with chain and tires protections against oil or dirt.[1]
City bikes may be individually owned or operated as part of a public bike sharing scheme.
