With regard to the maintenance of several small notebooks common sense! ! Please take a look at that time pump! ! !
Bought a new laptop battery should be three complete charge and discharge, in order to activate the internal battery of chemicals, so that the battery into the best condition. Usually do not frequently open and close the laptop, or else they will consume a large amount of battery power. If the computer is not a short period of time, it can be in a state of sleep or hang. The use of the Windows power management features, battery power consumption can be reduced to a minimum. Can also download a power management software used to manage power of books, recommended Le Power Center is a free service designed for notebook power management software!
First, the battery charge
In order to improve efficiency and ease of use, in the notebook battery charge is generally used when the fast charge mode, a charge time in the 1.5 to 3 hours. Ni-MH battery current approach to the general charge, and temperature control (that is, to a certain time interval check the battery’s temperature rise) or law-ΔV (Ni-MH battery capacity reached 100% before the battery voltage was gradually increased However, 100% charge capacity, because of its heat through the battery cell voltage drop, and so have a drop-ΔV) measured as a result of control of charging on the basis of whether or not to terminate, together with the TCO of control (with temperature Based on the charge to cut off, cut off the temperature of 60 ℃), to ensure the safety rechargeable nickel-metal hydride batteries. Lithium-ion inspiron battery chemistry in its decision to charge, first with the constant current charging mode, constant current charge to 4.2V when the (single-core or a few energy-saving power when the voltage batteries in parallel) into the charging voltage, Pressure dropped to 100mA charge current around, stop charging.
Although many notebook computer batteries using the wisdom of the battery technology can be accurately measured and the state of charge of battery life, allow users to use many of the worry, but the battery charge when we should pay attention to the following:
1. Rechargeable batteries should be for the ambient temperature 0 ℃ ~ 45 ℃ temperature scale. The process of charging the battery temperature will affect the charging efficiency and service life, so when conditions permit, the best lithium-ion batteries in 10 ℃ ~ 30 ℃ temperature range for battery charging, so as to achieve the best efficiency of the charge . Ni-MH battery is the use of temperature control or law-ΔV to detect whether the battery is full, the experiment showed that: charging the higher the temperature, the more it is not easy to judge whether the battery is full. Therefore, Ni-MH battery charge when the desired temperature in the 10 ℃ ~ 20 ℃ between.
2. If the laptop’s AC power adapter is not a great power, rechargeable batteries, if conditions permit so that the machine should be shut down or in standby mode without any operation. Because the notebook computer power adapter to power is provided by a certain, large load system (such as the use of hard disk drive or load time, and so on) the time allocated to the Latitude CPi battery  power on the small, it decreases the charge current, the current AC power adapter from the power margin decision. If the battery is less than the current requirements of the charge current, so if things continue this way will affect the battery’s working life. Some notebook computers on the statement called for the laptop battery will not operate this is the reason. We can power adapter and notebook computers rated voltage and current power adapter to calculate the margin of power, which decided to charge the battery when the need for shutdown. The method is simpler: To compare the shutdown and shut down both cases, rechargeable batteries used in time, if the difference more, this laptop’s battery charge in the best when it shut down.
3. To ensure that the use of your laptop’s power adapter match. Inappropriate power adapter may not be fully charged battery, or Latitude CPX battery  meter can not correctly display the battery power.
Second, the battery discharge
1. Can discharge the battery in -20 ℃ ~ 60 ℃ temperature range, preferably at -10 ℃ ~ 45 ℃, because the temperature is below -10 ℃ or 45 ℃ higher than when the battery discharge capacity Will be less than the rated capacity, leading to lower battery performance (with the exception of special applications, the vast majority of laptop users, the ambient temperature is generally not lower than -10 ℃ or higher than 45 ℃).
2. Whether or Ni-MH battery lithium-ion batteries, once the battery to the laptop power supply, and so that the best discharge the battery completely before recharging, which will help extend battery life. The so-called “full discharge” the battery is not fully put the power to do, but according to different types of batteries used to power batteries to allow the value of the minimum values to the battery voltage as a basis, such as nickel cadmium, nickel metal hydride batteries single Discharge batteries should not be lower than 1.0V, lithium-ion battery power-saving single-core discharge should be an end to 3.0V (should not be less than the minimum 2.7V), otherwise they will damage the battery. Because the notebook computer (or battery) has an internal control to monitor the discharge circuit (it will be based on the battery discharge condition and the work of the current machines to determine whether the Latitude C640 battery  can continue to work to maintain the machines), so in actual use, and we only need to battery The power to put 1% to 5% charge to start worrying about the battery discharge would be excessive. If the practice can not fully discharge each time, then at least every other month to conduct a full battery discharge, as the notebook computer on a regular basis to the full discharge can increase the storage capacity of the battery, extending the battery life of service.
