Indicates issues in the audio-out/microphone jack; such as faulty hardware, physical damage, software conflicts.

Battery light blinking amber

Low battery warning — battery charge is from 0 to 90 percent.

Blink = 3

The embedded controller has timed out waiting for BIOS to return from memory initialization.

Blink = 4

The embedded controller has timed out waiting for BIOS to return from graphics initialization, possibly indicating a missing or faulty MXM module.

Blink = 5

The system board displays a power failure (crowbar), indicating an extreme overcurrent or overvoltage event.

Blink = 7 (2 BB failure)

The embedded controller cannot find valid firmware or two boot block failures have occurred.

Blinking = 1 Hz (3 B failure)

Three consecutive boot block failures indicate a serious firmware issue or hardware failure.

Blinking Power light

Indicates computer in sleep mode or low power state, awaiting user interaction to resume.

Drain error — water is not draining from the unit

Indicates that there might be physical damage to the device, like water leakage.

E2

BIOS area not found — BIOS corruption issue.

F1

A diagnostic code generated when a hardware failure is detected by HP PC Hardware Diagnostics Windows.

Failure ID (24-digit code)

Hardware replacement is required as determined by diagnostic tests.

Failure ID code (24 digits)

A failure that requires hardware replacement has been detected during a diagnostic test.

LED blinks continuously amber

Indicates system overheating or thermal issues preventing startup or continued operation.

LED blinks rapidly amber

Indicates battery has reached dangerously low level or is not charging, possibly due to cable disconnection.

LED off when powered on

Indicates no power supply to the device or defective LEDs.

No light on Power button when pressing

May occur if power supply or charger is malfunctioning, leading to an unresponsive system.

Power light blinks

The computer is in Sleep mode.

Power light blinks rapidly

Critical battery level warning — battery reaches low charge or device fails to start.

Power light is off

The computer is turned off or in Hibernation mode.

Red LED flashes once and white LED remains on
