Ensure that no keys are stuck.
Startup problems
The computer does not start up when you press the power button.
Solutions:
Ensure that:
• The power cord is correctly connected to the rear of the computer and to a working electrical outlet.
• If your computer has a secondary power switch on the rear of the computer, ensure that it is switched on.
• The power indicator on the front of the computer is on.
• The computer voltage matches the voltage available at the electrical outlet for your country or region.
The operating system fails to start up.
Solution:
Ensure that the startup device sequence set in the Setup Utility program includes the device where the
operating system resides. Usually, the operating system is on the internal storage drive.
The computer beeps multiple times before the operating system starts up.
Solution:
Ensure that no keys are stuck.
Audio problems
The audio cannot be heard on the Windows operating system.
Solutions:
• If you are using powered external speakers that have an On/Off control, ensure that:
– The On/Off control is set to the
On
position.
– The speaker power cable is connected to a properly grounded, functional ac electrical outlet.
• If your external speakers have a volume control, ensure that the volume is not set too low.
• Click the volume icon in the Windows notification area on the taskbar. Ensure that the mute speakers
settings are not selected and none of the volume settings is set too low.
Note:
If the volume icon is not displayed in the Windows notification area, add the icon to the notification
area. See the Windows help system.
• For some computers that have a front audio panel, ensure that the volume is not set too low.
• Ensure that your external speakers (and headphones, if used) are connected to the correct audio
connectors on the computer. Most speaker cables are color-coded to match the connectors.
Note:
When external-speaker or headphone cables are connected to the audio connectors, the internal
speaker, if present, is disabled. In most cases, if an audio adapter is installed in one of the expansion
slots, the audio function built into the system board is disabled. Therefore, you must use the audio
connectors on the audio adapter.
