There is a major breakthrough in laptop batteries

The Mobile PC Extended Battery Life Working Group (EBL-WG) announced that its low-power display program achieved a major breakthrough, confirming an average annual shipment of more than 600 million pieces of no more than 3 watts power consumption, low-power 12.1/14.1/15.0 XGA display, expected to account for the total notebook shipments in 2004 to about 12%.
From a year ago to establish the program began, the display of the average power consumption has dropped from 4.3-4.5 watts to 3 watts or less - power savings equivalent to an additional 60 minutes of laptop battery life. EBL-WG's goal is to achieve an annual production of 1,000 early next year, 10000 no more than 3 watts power consumption display, expected to account for the total notebook shipments for 2005, about 20%.
Intel's Mobile Platforms Group, Mobility Enabling Initiative Manager and EBL-WG Chairman Kamal Shah said that the notebook computer display subsystem in notebook computers, the overall average power consumption occupies a large proportion. So far, notebook computers of the various components and subsystems, the display subsystem consumes the most power. Shah said: "With the new low-power display technologies emerge, the display subsystem must also consume less power, thus continue to promote the continued decline in overall mobile platform power consumption."
He said: "Consumers are demanding notebook computer with longer battery life time is increasing. If we are to achieve the ideal of all-day battery life, reducing the power consumption of notebook computer display subsystem is the key lies. "
EBL-WG milestone demonstrates manufacturers increasing desire to reduce platform power consumption to meet the users demand longer battery life. Recently joined the EBL-WG, several companies, including: AMD, ATI Technologies Inc, BIC, Infineon, Millennium Cell, Motorola Energy Systems Group, O2Micro, and Sion Power.

Laptop battery maintenance to note what

Notebook battery maintenance mode. . . . What is the taboo of laptop battery maintenance? Laptop battery life is longer, often cannot full charge, or even show damage, it must be used in attention to some maintenance tips: Whether you use the notebook lithium notebook battery(Dell Inspiron 1525 Battery) or Ni-MH battery, battery power as much as possible to the basic use to do after filling (capacity less than 5%), which is the best way to avoid the memory effect. In fact, the lithium-ion battery(Sony VGP-BPS8 battery ) has some memory effect, but much smaller than the nickel-metal hydride batteries Bale. However, attention is needed to carry out charging as much as possible to avoid too long, the general control within 12 hours.

Laptop battery life not by the length of the total use of time, but by the charge and discharge times to decide. Here is the importance of maintenance of notebooks. If the battery will always be loaded to a notebook instead of taking down, then even if the machine shut down and remove AC power, the battery would not have imagined, as has been maintained, as when fully charged state. Laptop battery because the battery in the integrated control circuit, so even shut down your computer when power is power. As one connected to AC power, the battery will begin charging, when turned on or off the power, your laptop battery will be charged and discharged repeatedly, affecting battery life.

To do this, use an external power supply when the AC is best to unplug the battery, or laptop battery(Dell XPS M1330 battery) a long life of their implications in the hot state. To maintain the battery for the long term do not, please charge and discharge at least once a month to ensure that its activity. In the custody of the battery when there is a need for attention. At present, the vast majority of notebooks used in lithium-ion batteries do not use if a long time, often prone to the phenomenon of excessive discharge, may no longer be able to recharge laptop batteries. In order to prevent over-discharge, can be in semi-charged state to save in a cool dry place, and then every six months, and then to half of its electricity charge state.

In addition, the factors that affect battery life books also include the use of the environment temperature (below 30 ℃ proposed use), battery storage and battery temperature suffered shock size. Laptop battery(Sony VGP-BPS9 battery) in use after a period of time will be aging (how care is the same), concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled with capacity is also naturally declined. The laptop battery correction is an effective way to deal with aging batteries, a small number of laptop battery calibration software will be dedicated. If your laptop not have a dedicated discharge software, then the battery can be maintained in accordance with the following steps:

● Disable the screen saver;

● In the Windows Power Management power scheme will be set to "always open";

● In the Alert tab will be "insufficient power warning" is set to 10%, the operation is set to "no action";

● will be "a serious power shortage alert," set to 3%, operating as a "pending";

● the screen brightness to the maximum;

● confirmed that closed all the windows, and keep all the previous work of the data;

● confirmed that over 80% battery charge after the unplug the power and all external devices.

Discharge after the notebook will automatically shut down after the power plug for laptop charging, this process can be repeated 2 to 3 times to let the battery continuous low current discharge, which discharge status in our daily use is not possible to achieve , the effects of the discharge and those dedicated basically the same software.

Battery fault analysis and diagnosis

We found that the battery(such as DELL XPS M1530 Battery) can not charge, and charging indicator light, flashing red lights three times, look at the green light flash, which is that the battery(Dell inspiron 1525 Battery) broken?We can be judged through the following steps.1.
