Graphics Controller Error (No Controller)

This computer has experienced a graphics controller initialization problem resulting in a failed start-up. This issue may be

related to the graphics controller in your machine. This problem may be resolved by ensuring that the graphics controller

module is seated correctly on machines with modular graphics. If this error reoccurs, a service event is required to identify the

source of the error and take the appropriate corrective action.

NOTE: The computer will attempt to notify the user of this problem through a series of blinking LEDs. When the user attempts

to turn on the computer from an “Off” or “Hibernated” state, LEDs associated with the CAPS and NUMLOCK keys will both blink

four times followed by a pause, then continue in a repeating pattern.

Sure Start has identified a problem (Manual Recovery Policy Set)

This computer has experienced a problem in locating a valid BIOS image, resulting in a failed start-up. HP Sure Start will

normally repair this type of issue, however, on this computer HP Sure Start has been configured to operate in manual mode

key sequence. To proceed with the repair, press and hold the following keys:<ESC>+<UP arrow>+<DOWN arrow> . It is

recommended the HP Sure Start recovery policy be set to automatic to avoid the need for this manual recovery step. If this

error reoccurs, a service event is required to identify the source of the error and take appropriate corrective action.

NOTE: The computer will attempt to notify the user of this problem through a series of blinking LEDs. When the user attempts

to turn on the computer from an “Off” or “Hibernated” state, LEDs associated with the CAPS and NUMLOCK keys will both blink

eight times followed by a pause, then continue in a repeating pattern.
