The only difference that you can make is how long before you need to replace your battery. Each manufacturer rates each battery model with a different number of charge cycles. It will just start degrading and lose its capacity. This may happen even sooner if you do not take care of your battery. Some people call this partial charging. Even the manufacturers recommend to do a calibration every 2 or 3 months.
In some situations users have reported Windows showing a broken battery after a few months of usage. The procedure for calibrating the battery is simple. Even though it sounds simple enough there are a few steps that you need to do before you can start with the calibration process. This procedure can be carried out on any device running a battery: any laptop with any operating system, tablet, mobile phone etc. You should see a blue screen after you turn it on. As long as it is not automatically shutting down, the laptop will continue discharging.
Is Laptop Battery Calibration Necessary? Enter the power management settings on your laptop after starting it up. Close all applications after you have updated all settings. Make sure the battery is fully charged by connecting the AC adapter. Run the unit until the power LED goes out until the battery is fully discharged. The battery should be fully charged a second time by connecting the AC adapter.
The power LED should go off again after the battery has been fully discharged. Setting your battery to power mode will not let it discharge properly. To calibrate it while not in use, click 'Choose when to turn off display. HP Battery Check is an easy-to-use tool, which can be run in order to verify the functionality of the primary and secondary batteries installed in HP Notebooks.
Check the battery charge. Turn on the computer and start Windows normally. On the desktop, hover the pointer over the battery icon in the system tray to view the battery charge percentage. If you plug in your AC adapter and immediately run the HP Battery Check, you might get a false failure showing the battery is bad. This BIOS utility provides a number of settings designed to improve battery longevity and performance for select HP business computers. Turn off the computer, and then make sure that the power cord is connected to the computer.
Turn on the computer, and then repeatedly press the esc key until the Startup Menu is displayed. The Battery Health Manager feature opens. Maximize my battery health : Use this setting if the computer stays plugged in to the power adapter most of the time.
Let HP manage my battery charging : Use this setting if the computer is operating under a heavy load or being used in hot environments. Charging behavior automatically adjusts to balance between maximizing battery health and maximizing battery duration. Maximize my battery duration : Use this setting if you need to have the battery fully charged when taking the computer off the charger.
Review the frequently asked questions about testing and calibrating the battery. HP provides diagnostic software you can use to test hardware components on your computer.
HP PC Hardware Diagnostics for Windows is a Windows -based utility that allows you to run diagnostic tests to determine whether the computer hardware is functioning properly. The tool runs within the Windows operating system to diagnose hardware failures. To download the latest version, go to the HP Hardware Diagnostics website. Review the following list for more information about the results displayed under either Battery Details or Advanced Information.
Charged or Discharging : Percentage displays how close to a full charge the battery is. Displays Charged when the power cord is plugged into the computer or Discharging when the power cord is disconnected. Primary Battery : Summarizes the test result for the primary battery. Warranty Type : Describes the warranty of the battery. Cycle count : The number of times the battery can be fully discharged and recharged. In the example, the battery has been charged and discharged 38 times out of Manufacturer : A code that indicates the manufacturer of the battery.
Battery Age : The number of days since the battery was manufactured. Serial Number : The serial number of the battery. Temperature : The temperature of the battery.
Design Capacity : Displays the designed charge capacity of the battery. Full Charge Capacity : Displays the capacity of the battery when fully charged. Remaining Capacity : Displays the remaining charge of the battery in milliampere hours mAh instead of a percentage. Current : The discharge current, represented in milliamperes mA. When the computer uses AC power, Current displays 0 mA. Terminal Voltage : The voltage output from the battery terminals.
Design Voltage : Displays the designed voltage of the battery. Cell Voltage : Each battery has up to four cells. Cell Voltage represents the capacity for each individual cell. If one or more of the Cell Voltage items displays 0mV , the battery contains three or fewer cells. Status : Provides a code indicating additional battery status information for service technicians. AC Power : Displays Yes when the power cord is plugged in, or No when the power cord is disconnected from the computer.
CT Number : This number is the identifying number printed on the barcode on the battery. Secondary Battery : Indicates the presence of another battery.
Recommendations for battery use and storage are covered in the HP User Guides for each model. Review this additional information on battery care practices. Do not disassemble, crush, or puncture a battery; do not short the external contacts on a battery; and do not dispose of a battery in fire or water. Do not leave batteries exposed to high temperatures for extended periods.
Prolonged exposure to heat for example, inside a hot car accelerates the deterioration of Li-Ion cells. Remove the battery if the notebook will be stored turned off and not plugged into AC power for more than 2 weeks. Remove the battery from the notebook if the notebook will be plugged into AC power continuously via an AC adapter or docking station for more than 2 weeks.
Use the type of battery with the highest capacity Ah rating if the notebook will run high-end applications on battery power. Calibrate the battery based on the usage model. Under normal usage, batteries should be calibrated a minimum of once every 3 months; however, a battery that is rarely discharged fully should be calibrated about once a month. Use only the battery provided with the computer, a replacement battery provided by HP, or a compatible battery purchased as an accessory.
You can manually change the power consumption of your notebook PC and conserve battery power. Reduce the brightness of the screen to the minimum readable level. Use the fn and f7 or f8 keys to adjust the brightness.
Remove peripherals when not in use. Disconnect them when you have finished using them.
