According to your description, I suggest you refer to the following information:
1, I suggest you try to download and install the battery testing software of the machine, and test the battery to see if there is anything wrong with it. If there is something wrong with the battery, it is recommended that you directly contact the Gold Medal Service Center for testing. If there is nothing wrong with the battery test, I suggest you try to calibrate the battery and see if you can solve the problems you encounter.
2. If you can't find the battery testing software of the machine, I suggest you use the following link to install and download it:
A battery testing software under XP system: You can test your battery with HP battery check manager battery testing software first. Under XP system, you can try to use this battery detection software to detect batteries. The download address is FTP://ftp.hp.com/pub/softpaq/sp49001-49500/sp49129.exe.
Remind you to plug in the power adapter when testing the battery, and judge the working state of the battery according to the test results. After installation, click Start → All Programs → HP → HP Battery Check.
B.Vista battery detection:
You can run the battery test software to test the state of the battery. Note: When testing, both the external power supply and the battery need to be connected correctly. , you need to install the following two links:
① HP active support library (sp34016): FTP://ftp.hp.com/pub/softpaq/sp34001-34500/sp34016.exe.
② HP help and support (sp36097): FTP://ftp.hp.com/pub/softpaq/sp36001-36500/sp36097.exe.
After installation, just run the battery check in Start-Help and Support-Troubleshooting.
C. win7 battery test:
Under WIN7, you can use HP support assistant software to check the battery: FTP://ftp.hp.com/pub/softpaq/sp47001-47500/sp47326.exe.
After the installation, double-click to open the HP Support Assistant software on the desktop, or click Start → All Programs →“HP”→“HP Support Assistant to select troubleshooting and diagnosis. Click "battery, heat and machinery", click "battery inspection", and then check the test results.
3, battery test results, meaning is as follows:
A) Good/Pass-The battery is in good condition and does not need to be replaced.
B) replacement-the battery needs to be replaced.
C) Calibration-It is recommended that the user recalibrate the battery and then run the tool again. If the retest result is still "calibration", the battery may not work properly and need to be replaced.
D) Unknown—The power adapter is not plugged in, so it needs to be plugged in.
E) weak (the battery is close to its service life and is caused by natural wear and tear. It is recommended to buy batteries).
B) replacement-the battery needs to be replaced.
C) Calibration-It is recommended that the user recalibrate the battery and then run the tool again. If the retest result is still "calibration", the battery may not work properly and need to be replaced.
D) Invalid—The power adapter is not plugged in, so it needs to be plugged in.
Note: If the detected battery status is "Replace", it is recommended that you contact the engineer of the local gold medal service center to help you replace the battery.
4. If you need to calibrate the battery, it is recommended that you calibrate the battery according to the following steps:
A. set the screen saver to "none"
B in Windows power management, set the power consumption scheme to "always on" and set all the following menu items related to equipment shutdown to "never".
C. Set "low battery alarm" to 10% in the alarm tab, and set the operation to "Do nothing"; Set the "Severe Low Power Alarm" to 3% and operate it as "standby" mode.
D, brightness level the screen to the highest level.
E ensure that all windows are closed and all previous work data are saved.
F after confirming that the battery is charged to more than 80%, unplug the power supply and all external devices. At this time, if the screen brightness automatically decreases, please turn it to the brightest.
G. After the discharge, the notebook will be automatically turned off, and then plugged in to charge the notebook. Please wait until the laptop is fully charged before turning on, and then restore the power scheme to the settings before calibration. The purpose of this is to make the battery discharge continuously with a small current, which is impossible in our daily use, because under normal conditions, we will inevitably carry out various operations that will make the current fluctuate up and down.
