HP Notebook PCs - Checking the Status of the Battery
This document pertains to HP Notebook PCs with Windows 7 and Vista.
HP Battery Check is a utility in HP Support Assistant that provides a simple but accurate test of the battery.
The maximum capacity of all batteries decreases with time and use. Loss of battery capacity varies with product configuration and usage, including but not limited to product model, applications running, power management settings, and product features. The battery warranty covers defects in materials or workmanship that result in failure; it does not cover natural deterioration of battery capacity. To determine if a battery has had a warrantied failure, you may need to run additional diagnostics.
To get the latest version of the HP Battery Check, download and install HP Support Assistant for Windows 7 and Vista.
NOTE: When installing or upgrading HP Support Assistant, the Battery Check option in the Power, Thermal, and Mechanical window may not appear. HP Support Assistant must run at least once to activate the program.
To resolve this issue, complete the following steps.
Check the battery status
To prepare your computer for checking the battery status, turn off the PC and connect it to the AC adapter. The notebook PC must be on AC power in order for HP Battery Check to function properly. The PC should be allowed to charge for approximately 30 - 60 minutes before trying to run the HP Battery Check utility.
If you plug in your AC adapter and immediately run the HP Battery Check, you may get a false failure showing the battery is bad. If the battery is in a low charge state (at less than 3%) you may also get a false reading.
Follow the steps below to check the battery using HP Support Assistant.
The current state of the battery (charging or discharging) is displayed.
