HP Sprout Maintenance & Service Guide

Interpreting POST diagnostic front panel LEDs
This section covers the front panel LED codes as well as the audible codes that may occur before or during
POST that do not necessarily have an error code or text message associated with them.
WARNING! When the computer is plugged into an AC power source, voltage is always applied to the system
board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect
the power cord from the wall outlet and allow the internal system components to cool before touching.
NOTE: Recommended actions in the following table are listed in the order in which they should be
performed.
Not all diagnostic lights and audible codes are available on all models.
Activity Beeps Possible Cause Recommended Action
White Power LED On. None Computer on. None
White Power LED flashes every
two seconds.
None Computer in Suspend to
RAM mode (some models
only) or normal Suspend
mode.
None required. Press any key or move the mouse to
wake the computer.
Red Power LED flashes two
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
2 Processor thermal
protection activated:
A fan may be blocked or not
turning.
OR
The heat sink assembly is
not properly attached to the
processor.
1. Ensure that the computer air vents are not
blocked and the cooling fan is running.
2. Check whether the fan spins. If the fan is not
spinning, make sure the fan's cable is plugged
onto the system board header.
3. If fan is plugged in, but is not spinning, then
replace fan assembly.
4. Contact an authorized reseller or service
provider.
Red Power LED flashes three
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
3 Processor not installed (not
an indicator of bad
processor).
1. Check to see that the processor is present.
2. Reseat the processor.
Red Power LED flashes four
times, once every second,
followed by a two second pause.
Beeps stop after fifth iteration
but LEDs continue until problem
is solved.
4 Power failure (power supply
is overloaded).
1. Ensure the power supply cable is seated into
the connector on the system board.
2. Check if a device is causing the problem by
removing ALL attached devices. Power on the
system. If the system enters the POST, then
power off and replace one device at a time and
repeat this procedure until failure occurs.
Replace the device that is causing the failure.
Continue adding devices one at a time to
ensure all devices are functioning properly.
3. Replace the power supply.
4. Replace the system board.
