Your computer has a program on it called quick launch. It could be that the function key won't work until the program is loaded up into the memory of your computer.

Compaq Presario CQ70-120US Widescreen Laptop PC Notebook: Why isn't the sound on the computer working?...


Well that could be a couple things, the sound is turned off. Check the volume control, or make sure the laptop isn't muted. It's usually a function key and one of the volume icons on the keyboard. Lastly it may be a corrupted sound driver. Reinstall the audio/sound driver by visiting HP.com and downloading the driver from the support section. Best of luck.

Lost the sound on my compaq key board has a orange light on by the mute button but i can't get the light to turn off


That definitely means the sound is muted, is the rest of the keyboard functional? I believe there is an option to turn off the mute in control panel under hardware and sound. However, I am unsure.

Sound problem


Check all the usual suspects. Windows Volume, speakers volume. Make sure its not muted in the hardware. There is a key function that can mute or change the volume.

Its the light blue function key at the bottome left ( usually). You hold that down and press the light blue volume button ( usually at the top left or right keys.

Did it work one day and just stop?

Also go into the sound settings and make sure the sound device for the laptop is selected.

If none of these things work, you may have a bad sound card on the mother board which requires a new Mainboard.

I would have someone who knows about computers give it a once over. find someone you know who can just give it a quick once over before spending any money.

Alot of times the Key function volume controls will get turned off but still shows that its on in windows. Depending on the laptop
