My earphone do not play
my laptop keeps showing earphone not plugged in when it is even inserted. is it a hardware problem or software problem and how can i solve it.
More than likely it is a faulty earphone socket. There is a contact within the socket itself which 'tells' the audio controller when a plug has been inserted, so that the sound can be re-directed from the internal speakers to the earphones.
It may also just be a loose connector cable from the board to the motherboard, so check for that first.
Here is a link to the service manual for your laptop. Scroll to Section 4-34 for information on how to remove the audio board, attached to which are the mic and earphone sockets.
Here is the part number for the board.
Audio board (includes audio board cable) - 486634-001
Here is a link to just one supplier of the spare part, to find more just 'google' the part number.
Hopefully this is of some help.
