My laptop is Dell,the internal speaker not stop working but only work when i use hearphone.
May be there is wiring problem with the internal speakers. You know the real meaning of peace only if you have been through the war.
If the speakers only work when the phones are plugged in it is possibly a faulty headphone socket on the PC. If so, sometimes plugging in and out the phones quite quickly several times can fix a contact issue. Always pop back and let us know the outcome - thanks
benna, Your question was a little confusing. Are you saying that the laptop speakers only work when you plug in a set of headphones or external speakers?
Do the headphones or external speakers also work when you do this?
Was something incorrectly plugged into the headphone jack at some time in the recent past?
Derek's answer might work. You could also try a can of compressed air and blowing into the headphone jack.
