The sound icon just disappeared and I went to the controlbar but could not find the solution there? These is currently no sound on my laptop - sound is muted?
If the sound is muted go into the Volume control and uncheck the Mute box.
If this does not work then reinstall the audio driver.
You can download the audio and device drivers from the Compaq/HP WEB support/download page. Make sure you select your model laptop and the Windows drivers you require and install them. Click on this link to download the drivers: -

This could be a simple driver glitch. Try uninstalling the audio drivers from the device manager, then reboot. The machine will find he sound card and reinstall the drivers automatically. Then go to HP's support site and check for any updated sound drivers or patches. If it's a glitch this will fix it. Keep in mind that it could also be a hardware problem with the mute switch, so if the driver procedure doesn't work, you might consider having it serviced.

go to device manager and uninstall the sound drivers and restart the system and if the drivers are automatically detected good enough if not install the drivers again

sounds like it's a physical problem not software, but to be sure i would update the audio drivers and see if that helps.
go here and pick your system and follow the steps to get any new drivers and install and see what happens.

Did you inadvertently move the task bar below the bottom of the screen per chance?
If you are plugged in, the battery icon will be replaced with a plug.
