Tip & How-To about Computers & Internet
Battery Mark test principle is to use the built-in four engines to simulate the actual operating conditions to consume battery power. This four engines are the Graphics engine, Processorengine, Diskengine and Thinkengine. ".Graphics engine built-in Battery Mark by calling the procedure a sample LCBTP03003, such as Photoshop, Dreamweaver, etc. to simulate the actual use to deal with graphics, web pages and documentation process.
Processorengine to CPU occupancy rate increased to 100% instantly and maintain a period of time to simulate the CPU high load power consumption of under working conditions.Disk engine through repeated read and write operations on the hard disk to simulate the actual use of the power consumption of these drives on VGP-BPS8 VGP-BPS9, when you can see the hard disk light flash in the mad.Thinkengine is a simulation of the actual situation of users in the process of thinking.
Test, Battery Mark will be in the 4 cycle engine, constantly switching between Pavilion dv2000 Battery Pavilion dv6000 Battery HSTNN-LB31, followed by testing a variety of operating environment, this four engines can be fully integrated with the specific circumstances of the test battery. Each had 2 to 3 minutes Battery Mark test data will be automatically saved to the user to set the directory below. Completely exhausted the battery, the computer automatically shut down the last time before the results will be saved as the final test results. 4, repair laptop computer batteries methods
(a) causes damage to the battery,
notebook computer battery life is longer, often dissatisfied with battery charge, and even show the battery has been damaged, concrete expression of the resistance is bigger, at charging voltage is increasing relatively quickly at both ends. So easy to charge control circuit has been judged already been filled powerbook G4 ac charger powerbook g4 power charger, the capacity also falls. Since relatively large battery internal resistance, discharge voltage drop big, fast, so the system is easy to mistakenly believe that voltage is not enough electricity shortage. The discovery of relatively short battery life, should take appropriate measures.
(B) The battery refresh program to restore the battery discharge time
Big-brand notebooks have a battery refresh program, we can use it to repair the battery. For example: a IBMThinkpad390/262650-based notebook computers, are fitted with nickel-metal hydride batteries (Ni-Mh) batteries, due to normal charge and discharge properly, leading to the Pavilion dv2000 Battery and Pavilion dv6000 Battery discharge time is shorter, leaving less than 5 minutes, if the bring notebook computers to work, then it is very inconvenient, what methods can restore the battery discharge time then?
In response to these circumstances, we can use the IBM has launched a battery refresh program to refresh the battery put it back in discharge time, specifically as ibook g4 charger APple A1021 charger.
(1) the use of AC power to the notebook computer, first to ftp://fip. pc. ibm. com / pub / pccbbs / mobiles / isbr01ww. exe download software provided by IBM notebook computer batteries TP390/390e/390x refresh program. Wsvk
Ray (2), restart your computer, press F8 key to enter boot menu and select safe DOS mode.
Ray Pride (3) into the directory where the file you just downloaded to Compaq laptop battery, the implementation of the battery refresh program isbr0lww, exe, reading a warning message, by asking you to insert a floppy disk, and then press the Enter key to the implementation of the self-extracting operation.
Ray Pride (4) boot floppy disk with this computer, the screen appears StartingPC-DOS. . . Tips.
Ray (5) Follow the prompts to unplug the AC power to Apple, the program will automatically pairs of Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.
(6) due to the battery temperature is higher at this time should not start immediately Sony VGP-BPS9, so that the battery cool for a while, the plug in AC power.
(7) to guide the computer with the floppy disk, this Autoexec. bat file will run automatically refresh program, and asks the user whether to proceed. Select yes, press the Enter key.
(8) At this point into HP, refresh program began to refresh the battery, the process quickly, when the return to DOS prompt A:> when that refresh has been completed.
(9) Turn off the computer, and recharge the battery until the green indicator light up.
Ray Pride (10) The above procedure repeated three times to get the best results.
Also, many battery pack lithium battery failure is the failure of a power-saving result of the core, this phenomenon can not be avoided. Because each section of the battery core properties can not be fully consistent with some of the quality of somewhat less long after the beginning of aging and the undermining of the whole (series after) the discharge curve to Acer BTP-58A1 Acer LCBTP03003. Interest and ability readers can try to open the battery pack, in the multimeter's help, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product.
