**HP UEFI ONLY** Checking battery health

  • If the HP UEFI diagnostics detect a persistent inaccuracy, a calibration will be recommended - this EliteBook 640 G9 does not need it, so it was not presented to me.

  • In order to check the battery health on HP laptops, you MUST use the UEFI tool as HP hides the actual heath data from the operating system. The tool can be downloaded here and written to a USB drive, or a secondary partition on the laptop - the choice is yours.

  • Run the HP diagnostics and do the following to access the battery test:

  • Locate Power in the diagnostics

  • Click on Battery and select Run once. This will take approx 2-3 minutes.

  • NOT SHOWN HERE Click on Battery details to review the health data.

**仅限HP UEFI**检查电池健康状况

如果HP UEFI诊断检测到持续的不准确情况，将建议进行校准 - 这台EliteBook 640 G9不需要校准，因此没有向我提示。

为了检查HP笔记本电脑的电池健康状况，您必须使用UEFI工具，因为HP将实际的健康数据对操作系统隐藏。该工具可以在此处下载，并写入USB驱动器或笔记本电脑的第二个分区 - 您可以选择任意一种方式。

运行HP诊断程序，并执行以下操作以访问电池测试：

在诊断程序中找到电源。

点击电池，然后选择运行一次。这大约需要2-3分钟。

此处未显示，点击电池详细信息以查看健康数据。
