6 FAQs about [System battery information query]
How do I complete a battery query?
To successfully complete the query, a new battery tag is required. Acquire the tag using the IOCTL_BATTERY_QUERY_TAG operation. If a battery is present in that slot, the tag returned can be passed to any of the other battery IOCTLs to perform other functions.
How do I display battery properties in PowerShell?
The following PowerShell script will display the properties information for any batteries available to the Windows system. The script makes use of the Windows Management Instrumentation (WMI) to fetch battery information and then presents it in a structured manner. Read-Host -Prompt "Press Enter to exit..."
How do I know if a WMI class is on battery?
On Battery: When on battery, it will also display the Estimated Run Time. I’m pulling the battery information from several WMI Classes and two name spaces. From this Class, I’m using EstimatedChargeRemaining, which is a % & EstimatedRunTime, which is in Minutes. I then head over to Root\WMI and look at the Battery Classes there:
What does ioctl_battery_query_tag mean?
This indicates to the caller that the battery associated with the tag longer exists. The caller may opt to use the IOCTL_BATTERY_QUERY_TAG operation to determine the tag of the newly installed battery, if one exists. (See Battery Tags for more information.) When a query information request is made, this value is verified.
How do I know if my system has a battery?
(Some older nonstandard battery systems and UPSs are not supported.) Note that this overview assumes you are familiar with device management. To obtain information about the battery status, use the GetSystemPowerStatus function, which returns general information about all power sources in the system.
What happens if a battery tag changes on a multi-battery system?
On a multi-battery system, each battery device (slot) issues battery tags independently, so the tag from two separate devices could at times be identical. A change in the battery tag does not necessarily mean that the battery was removed and reinserted or replaced.
