No sound from speakers or headphones fan not working gets warm

Inside the headphone socket there is a small lever that disconnects the feed to the speakers. When working normally, you would still get sounds in the headphones or sound from the speaker. Try spraying some switch contact cleaner into the socket to clean that switch.

These are analog speakers and do not need a driver. First, make sure they're plugged into the speaker/headphone jack and not the microphone jack. Second, make sure the computer's sound output is enabled and set the headphone/speaker jack. Third, verify that the sound output is working by plugging in a headphone set or a different pair of speakers. If the computer sound checks out, the speaker cable is bad or the power supply is not working.

Is it a fan noise?

It could be either internal speaker damage, internal circuit damabe or problems with the headphone jack. Try plugging in headphones if you have sound then you have no internal circuit damage. Try cleaning the headphone port with a cut off Q-tip. Also sit it in a warm dry place for a few days. If the sound still does not work the speakers may need to be replaced.

Fix the headphone jack to contact headphone pin. Fix the speaker contact in headphone jack to get sound to speaker when headphone is not plugged in.

Most likely its a nardware problem.
If Device manager shows the audio driver is working and enabled and when you plug an headphone into the headphone/audio out and you only get sound from the right headphone then the audio amp chip is faulty.
If the headphone sounds OK then the easiest solution is to connect a set of powered speakers to your laptop.

Are you have the headphones and speakers both pluged in? When you plug in headphones the speakers get muted. You need to change your sound settings back to your sound card if you use usb headphones. The plug on the front of the 4700 also automatically mutes the speakers.

So sometimes laptops play up when the headphone socket gets a bit worn. If you wiggle a headphone jack in the socket (put it in at different angles, and rub around) sometimes the sound will come back.

There are two prongs that "detect" the headphones, and cut the speakers... and if they don't "un-contact" when the headphones are removed, the speakers stay off.

You'd need someone to solder a new headphone socket on the mainboard to properly fix it, but if you wiggle and get the speakers back, they should stay back until you use the headphone socket again.

Connecting headphones to the system will disabled the internal speakers until the headphone jack is disconnected, at which such time the internal speakers should function again.

If you disconnect the headphones and the internal speakers are not re-activated, then there may be damaged to the microswitch in the jack. (Try rebooting after the headphones are disconnected too)

Hello Again,

When you Plug in HeadPhones into the Laptop the Sound Playing should automatically Bi-Pass the Speakers and go Straight to the Headphones

-Unless there is a Faulty Input for the Speaker/ Headphone, Try Pushing in the Headphones More to see if the Speakers Turn Off
