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

sounds to me like the indicator light is stuck in the on could be something touching the wires and causing a bad connections

Is the volume muted or not when the light is orange? If it is muted then use the icon on task bar and increase the volume, to see if color changes. If it is not muted and a change of volume does not affect the color of the light, maybe that is the normal color for it. Did you read the manual and find that orange means trouble. On my computer, the light for my WifI is always orange.
The speakers may be muted by an Fn +Fx key sequence, or some additional buttons on the computer.

please clarify orange light from where? white lights?

i think theres no installed sound driver

when it power on, your monitor power led turn to green or orange? if its turn to orange, your video card migth be the problem..

if there is a touch pad across the top with lights for sound mute etc. there is 1 in far right corner top right if it is orange the wireless is off touch the orange light it should turn blue if it does the wireless will be turned on ready to use.
if it does not go to control panel click on programs and unistall the hp wireless assistance and reboot the computer.
then after a reboot the wireless light should go blue.

Hi, Please update Sound driver from Hp.com and try
If you dont have any control on Quick launch buttons to turn on Volume, update Quick launchdriver. If that does not fix the issue, if you have to replace Speakers on the laptop

what is the model
u may need ti instal the sound driver that may help

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

you have to install the driver
get you driver driver through hp site
