Simple laptop battery charging diagnosis

With the increasing complexity of laptops, notebooks and netbooks, find out why a laptop battery is not charged is not easy. laptop batteries that die suddenly or notices as "laptop battery is not recognized" trigger valid reasons to be suspicious. Even more - simply replace a laptop battery dell latitude d830 is an expensive and certainly not always the solution. Today there are many components involved in charging a laptop battery. In this story you'll find a simplified approach to the reduction to a problem of laptop battery and leads to a possible solution.

Simple battery charge Laptop Diagnostic

Simplified diagnosis assumes the following;



1) works with AC power from the laptop - laptop battery will not charge.



2) the laptop battery has worked before in the same laptop



The approach involves the architecture of the smart battery system developed by Duracell and Intel. A Dell Latitude D610 laptop business is used as an example.



Although the information may not apply in all cases, you may still shed light on the reasons why a laptop battery will not charge.



Diagnostic approach

The diagnostic approach is based on the observation that all components of the burden of laptop battery is activated when the laptop is off with AC power adapter connected. This is true for most notebooks and eliminates the participation of the main processor of the burden of a laptop battery.



charging the laptop battery is administered by a second processor to the motherboard of the laptop. In this approach, the second processor is identified as the POST (Power On Self Test) controller. The controller executes during the initial test and manage the load on the laptop battery. While this may not be applicable for all laptops, the observation mentioned above still stands.



When the notebook is turned on the information on the burden of dell precision m90 battery can be controlled through either through the BIOS setup screen or eg Windows or Linux. Laptop battery charge following diagram shows the components involved in charging a laptop. The text marked in blue and red indicates the text, click-power and load pages with more information.

Laptop Battery d830 Life Problems

A few years ago, laptops are used by business entities. This is because it costs a lot. Today, many home users also use laptops rather than desktops due to its portability. It has also become more affordable to buy than before. The laptops are mostly powered by lithium ion batteries. This is a type of battery can be recharged with energy. The life of a laptop battery usually lasts two or three years, but also depends on the intensity of use. Laptop batteries laptop battery dell latitude d830 can be charged and recharged four times or more. However, these batteries do not last a lifetime. Sometimes, some factors that contribute to reducing the lifespan of laptop batteries. The following are common examples.

1. Excess drainage and recharge. You should only depletion of the laptop battery once a month. However, there are times when we forget that we are using a laptop and not a desktop computer. We left the laptop on for even 24 hours online, or leave it to shutdown. This is a bad practice, taking into account that you can still depreciate. Any object fades in time and the batteries are no exception to this.

2. increasing energy. Sometimes, our laptops plug directly into AC without even removing the battery. This can sometimes be dangerous because the AC means alternating current. You can not tell if there is a sudden increase in voltage. Laptop batteries can only absorb certain levels of voltages. If you leave the laptop with the battery and connected to AC power pa-1900-02d, and if a power surge that could damage the battery, reducing its useful life.

3. Raspberry ants. Yes, there are insects that love consumer electronics. Raspberry ant is an example. She loves being behind the light switches, a hot spot, and electronic devices. These ants can go inside the power supply in your laptop and your hardware. You can put the dust and even their own dead bodies in the electronic parts like the motherboard. Sometimes you can attack the battery. If this happens, then your only option is to buy a new battery or a new unit.

4. The excess of connecting devices to your laptop. Laptops can only supply a maximum power level of devices you can attach to it. Generally, those who consume the energy of the laptop are external devices such as external drives, mice, printers, and refrigerators. Of these, refrigerators are more damaging, as they require more energy than other devices. The battery will deteriorate rapidly if you use it often.
