hp laptop battery about memory effect

Use rechargeable batteries for laptop computers, one of the relative advantages of the desktop, it can greatly facilitate a variety of environments the use of Hp dv1000 battery. Introduced the first battery is nickel-cadmium batteries (NiCd), but this battery has a "memory effect", each charge shall be required before discharge, very easy to use, and soon was nickel-metal hydride battery (NiMH) replaced, NiMH not only failed to "memory effect", but can make more per unit weight of 10% of the electricity. The most commonly used battery is lithium-ion battery (Li-Ion), it is also no "memory effect", as compared with the NiMH per unit weight gain more power, the price twice as high than the NiMH. In the same weight, this three kinds battery is 1:1.2:1.9 ratio. There is also a battery-called polymer, a very high capacity, small size, most used in Apple Computer.

laptop computer batteries currently used in three kinds of main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI.

The purchase or replace the battery when the laptop for many users, the "batteries" may be unfamiliar. The outset, batteries and battery are two concepts. A battery is composed of several slightly larger than the thumb, cylindrical, height of about 7,8 cm, voltage is 3.6v of small units, a professional name for that is called 18650, Sanyo and Samsung is the largest producer. Batteries , like a small battery, through the series combination, that is, we see the battery has. Then talk about how to determine if the battery is several cores:

One way: Disconnect the battery to the number of contacts to see him, there are a few of the tens of cores. But this is a "minister" approach. Let's take a look at "Cao Chong" is how, "said the elephant": the look of your battery nominal number of v, such as 14.4v, and then divided by 3.6 to be 4, then proved to be four batteries together in series. And then take a look at the capacity of the Hp dv2000 battery block, for example 4400mAh, then prove that the above mentioned two sets of batteries in series, because the small battery capacity is 2000-2200mAh, or even more, and together the two groups can be achieved must be 4400mAh. According to these two judgments, then the battery is 4 × 2 = 8 cores.
The composition of laptop battery

Laptop battery from shell, circuit boards and batteries, belonging to lithium-ion battery. People are talking about batteries in general refers to the number of batteries within the battery, mAh refers to the laptop battery capacity.

Mainly by the protection circuit board (or the secondary protection circuit), and the capacity of directed circuits of two parts, laptop battery charge and discharge and safety management. Laptop battery standby time mainly by the mAh value to decide. Under normal circumstances, a few more batteries, mAh value is greater the longer standby time. Laptop battery life mainly by the charge and discharge times to measure the quality of the products are generally eligible for 500-600 times. Therefore, the effective use of laptop batteries within a period of two years, expired the battery will be aging, standby time affect the sharp decline in the mobility of laptop computers.

Laptop battery tips
In fact, how to make good use of laptop batteries battery, how to extend their use of time and the use of life and so on, is undoubtedly the troubled minds of the majority of laptop users, a problem, the use of laptop batteries There are many methods and techniques, which requires us to usually use more learning and application.

(A) rapid access to hibernation
Temporary non-use of laptop computers, in order to conserve battery power, we can set the power management program, allowing the system to enter sleep mode after a period of time, but this is a shorter or longer will have to wait a few minutes, there is no way to make laptop computer system immediately enter the sleep state? laptop computer system to enable quick access to dormant state of a simple method is to directly close the display. Press the display would require little effort, you can make laptop computers into sleep mode immediately and effectively conserve battery power. When you need to re-used time, as long as the opening screen, the system will automatically return to pre-operational state.

(B) the screen-saving mode
TFT screen is the largest laptop computer power components, in order to reduce its use of the battery when the power consumption, laptop manufacturers have devised ingenious schemes, but in general are based on the lower screen brightness, and even turn off the screen method. In some laptop computer's power management settings you can customize the brightness of the screen, most of laptop computers by a specific shortcut keys adjust screen brightness, generally 6 to 8-level brightness adjustment.

(C) energy-saving settings
Desktop machines using alternating current, most people may not be the computer attached great importance to energy-saving features, but need to use battery-powered laptop computers, the use of energy-saving features should be taken seriously. How to design computer hardware more energy-efficient, this is not a user problem to be solved. The user can do is set up on the Hp dv6000 battery the effective use of energy-saving option.

Energy-saving settings require the user to adjust two: First, the computer's BIOS setup program on the energy-saving mode in the settings.most important thing is there are many energy-saving in the operating system settings and operations. In the practical implementation of computer systems, Windows systems should take precedence over energy-saving settings in the CMOS settings.
