HP MaxiLife® Hardware Monitoring HP MaxiLife is a hardware monitoring chip which is resident on the system board. Its responsibility includes On/Off and reset control, status panel management (Lock button, LEDs), hardware monitoring (temperature and voltage), early diagnostics (CPU, DIMMs, PLLs, boot start), run-time diagnostics (CPU errors, package intrusions), and other miscellaneous functions (such as special OK/FAIL symbols based on a smiling face). HP MaxiLife Architecture The HP MaxiLife chip continuously monitors temperature and voltage sensors located in critical regions on the system board. This chip receives data about the various system components via a dedicated I2C bus, which is a reliable communications bus to control the integrated circuit boards.
