Noise (sound)

Items Procedures

Symptoms

Computer emits abnormal noise

Possible causes

Aside from basic components (power adapter/supply, fan, speaker, hard drive, optical drive,

display panel, external devices), it is also common for electronic components to produce

noise.

Troubleshooting steps

1. Inspect external power source and change to veried working one.

2. Determine whether the noise comes from AC power adapter. Test with a veried

working AC adapter.

Disconnect external devices and all cables connected to the computer to isolate issue to

computer only.

Noisy fan Determine whether the noise comes from the fan. Disconnect the fan briey to isolate

whether noise originates from fan. If noise is absent with fan disconnected, refer to Fan runs

constantly on page 133.

Noisy hard drive Determine whether the noise comes from the hard drive.

See Noisy hard drive on page 130.

Noisy optical drive 1. Determine whether the noise comes from an optical drive.

2. Remove CD/DVD from the optical drive.

Noisy speaker 1. Determine whether the noise comes from speaker.

2. Test with a veried working external headset/speaker.

Noisy display Determine whether the noise comes from display panel (humming noise). Change display

frequency settings. See Display on page 112.

The section below is intended for authorized service providers/technicians.

1. After disassembling the chassis, inspect components of the interior for excessive wear

or damage.

2. If noise issues persist, proceed with process of elimination for battery, AC adapter, or

boards.
