Power supply may be bad Long continuous beep tone Memory failure Steady, long beeps Power supply bad No beep Power supply bad, system not plugged in, or power not turned on No beep If everything seems to be functioning correctly there may be a problem with the 'beeper' itself. The system will normally beep one short beep. One long, two short beeps
The ATX specification defines the Power-Good signal as a +5-volt (V) signal generated in the power supply when it has passed its internal self-tests and the outputs have stabilized. This normally takes between 0.1 and 0.5 seconds after the power supply is switched on.
Some devices may expose such attributes in multiple "pages", as for example one page managing each power supply rail (maybe 3.3V, 5V, 12V, −12V, and a programmable supply supporting 1.0–1.8V). The device may set warning and fault limits, where crossing a limit will alert the host and possibly trigger fault recovery.
This can often be done through a section within the BIOS, or, once an operating system is running, through a system monitor software like lm_sensors on Linux, envstat on NetBSD, sysctl hw.sensors on OpenBSD and DragonFly BSD, or SpeedFan on Windows. Most power supply fans are not connected to the speed sensor on the motherboard and so cannot be ...

The SMBus clock is defined from 10 to 100 kHz while I²C can be 0–100 kHz, 0–400 kHz, 0–1 MHz and 0–3.4 MHz, depending on the mode. This means that an I²C bus running at less than 10 kHz will not be SMBus compliant since the SMBus devices may time out. Many SMBus devices will however support lower frequencies.
