Consumers Recognized "Disease" - Battery Endurance tTme is Short

Has become consumers recognized the "common problem" for the laptop, the hp ProBook 6540b Battery life is short. Cause laptop short life time in battery mode, then in the purchase and use of early, we should all advance from what has been understood and carried out to circumvent it?As we all know, even if you're just a little to increase the brightness of the laptop screen, plus a memory or plug in a mouse expansion card what will shorten the life of the laptop battery mode, it is very realistic to say: laptop battery life time will always become the people's frustration, because at least no qualitative change in a short period of time, then we really can not do anything? could only watch was only three to five hours of battery life time is reduced to a two hours? answer of course is no.First of all, unless it is necessary, otherwise we try or not in hp HSTNN-OB42 Battery mode using a laptop, the best in the mains environment, especially for prolonged use of laptops, not the expectation The laptop battery bring you much convenient, even if you book the battery life eighty-nine hours.Second, if so, under battery mode, it is best not to use too many laptop peripherals or functions, for example, if the use of the environment or conditions allow, the best display brightness to the lowest, unplug the mouse use the touchpad, turn off the built-in network card or sound system, in short, to do to maximize the life time, you must have the "sacrifice", this time using a laptop computer is a bit painful.The last is that the recommendations of the cliché, to your laptop ready twelve spare battery, this is the most sensible and effective solution for people who often use battery life.Existing laptop battery technology product background, to get longer battery life time is still a dream, especially when the premise of the lithium-ion battery technology products still dominate, but there is no quality of life to enhance the laptop The wide range of battery life time "breaking ten (hours) of the road is still far away.
Laptop battery repair method(A) The battery causes of damagehp EliteBook 8540w Battery use for a long time, it is often sufficient dissatisfaction power, even display the battery has been damaged, the specific expression of the resistance larger increase in the voltage across the charging faster. So easy to charge control circuit is judged to have been full capacity will naturally decline. Relatively large battery internal resistance, discharge voltage drop, high speed, so the system is easily mistaken for the voltage is not enough, the lack of electricity. Found the battery operating time is comparatively short, appropriate measures should be taken.(B) The battery refresh program to restore the battery discharge timeBrand laptop has a battery refresh program, we can use it to repair the battery. Example: a laptop with the battery for the nickel-metal hydride (Ni-Mh) batteries, due to the usual improper charging and discharging lead to battery discharge time is getting short, only less than 5 minutes, if carrying a laptop to work, it is very inconvenient, what can restore the battery discharge time?The response to these circumstances, we can use the notebook official website launched battery refresh program to refresh the hp Pavilion DV7 series Battery, put it back in the discharge time, specific methods are as follows.(1) the use of AC power for laptops, the first official website to download to a laptop refresh program.(2) Restart the computer, press F8 to enter the boot menu and select safe DOS mode.(3) to enter the directory where the file you just downloaded, perform a battery refresh program, read the warning message, asked to insert a floppy disk, and then press Enter to execute the self-extracting operation.(4) with this floppy disk to boot the computer screen prompted.(5) Follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.(6) due to the high temperature of the battery should not immediately start, let the battery cool for a while, plug in the AC power supply.(7) to boot the computer with a floppy disk, this file will automatically run the refresh program, and asks the user whether to proceed.(8) In this case, the refresh program began battery refresh process back to the DOS prompt A:> when the refresh is complete.(9) Turn off the computer and charge the hp 484170-001 battery until the light turns green.(10) The above process is repeated three times to get the best results.In addition, many lithium battery failure is the failure resulted in battery packs in a power-saving core, this phenomenon can not be avoided. Because each cell batteries can not be completely consistent in nature with weakened for a long time after some quality begin to age, while the destruction of the whole (series after) the discharge curve. Interested readers can try to open the battery pack, and the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, the replacement under the corresponding parameters of batteries can be qualified product.
