It is precisely because of the portability notebook did not come until everyone’s favorite, but if a laptop is not a high-quality notebook batteries , notebook can not guarantee the stability of long hours of work, the use of laptop notebook must have an external power supply, then lost the notebook on its own significance. But batteries are consumables, work to stabilize the general time in a year or so, then it may “suddenly dead.” If you are planning to buy laptop computers,dell GD761 , KD476, sony VGP-BPS2C laptop battery would need to do a physical examination in order to detect the battery problem.
Procedures for measuring systems
Windows XP comes with the use of the procedure can check the battery status and the use of time estimates. Fully charged battery first, and then unplug the power adapter notebook. Into the “Control Panel”, open the “Power Options”, see “Power List” option in the remaining laptop battery power, this time can be estimated based on the current operation of the program can also use battery time, click the “batteries for more information” also can be seen that the battery models, manufacturers and other relevant information. However, this method results in a single test, and as a result of the operation of the different circumstances there will be differences in power consumption, therefore, the credibility of test results is not high.
Using specialized software testing
There are laptop battery is designed to test the software, use the software testing can be obtained of the degree of information than the system testing will be high, there is USB friends, we might as well take the time to buy these second-hand notebook peer software. 1. Battery Mon “Battery Mon” is a shared software, you can use before registration for 30 days. “Battery Mon” to reflect detailed information on batteries, can record gd761 , kd476 battery discharge curve is smooth, but also according to the actual rate of decline in electricity consumption is estimated that the use of battery time, and software and built-in contrast to standard time. And the relatively short test time. Step 1 First of all, the battery fully charged, and then run the “Battery Mon” and unplug the external power supply. Step 2 Click “Start” after, “Battery Mon” to start recording on the decline curve of battery power. About 2 ~ 10 minutes after
Will generally depict the curve of the decline in consumption, when in the “Comparison Rate” and you select a power curve of the measured inclination of the most similar to the standard curve, so that batteries can be generally aware of how long it will be able to use. Click the lower left-hand corner Tips “Battery Info” button, you can view detailed information about the dell laptop battery . Although the “Battey Mon” to provide estimates of the use of battery time, but this time in real time in accordance with the current calculation of the drop in consumption, so that testing methodology is not sufficiently rigorous, but it is simple and convenient operation, suitable for beginners to use. 2. Battery Mark “Battery Mark” is an old dell inspiron 6400 battery test software. “Battery Mark” Built-four engine, four engine to make use of this comprehensive test of the specific circumstances of the notebook battery. Step 1 will be fully charged battery, run “Battery Mark” (At this time there is no need to unplug the power), follow the prompts to enter your basic information. Step 2 to enter the main interface can be seen after four
Option. First click on “Run”, then “Battery Mark” on the basis of testing a number of systems, if not the configuration of the notebook will not be able to run this program. If passed the test, click on “Finish” to enter the test page. Step 3 here “Battery Mark” program offers two tests: Conditioning Run and Life Test. Conditioning Run is called Graphics engine (Image engine), Processor engine (processor engine) and Disk engine (disk engine) that three engines, and in this between the three non-stop cycle of the engine switch to simulate the actual use of notebooks “torture”, quickly drain battery power. Life Test and the relative number of Conditioning Run a Think engine (thinking engine), but this process is the simulation we use in the process of peace will be carried out with the testing process has become longer and longer. Normally you can not have been running the program, there will be time to think. As a result of more Think ngine, Life Test of Conditioning Run time will be extended for more than 30% ~ 40%. When you choose a good test program, press F3 to start the formal testing, and then need to first unplug the power adapter. When the battery test, after a few hours after consumption of photovoltaic capacity, the system will automatically shut down when power adapter to plug in, boot after the “Battery Mark” will be automatically run and test results are displayed. How to, the operation of these two software will not be difficult for you? Whether you want to still want to buy second-hand laptop battery for their physical examination to look, choose one can be a good
Test results. Tips In general, notebook battery life of 300 ~ 500 times, so do not test the battery regularly.
