I am having this issue to which, whenever I slightly bend or tap the left and right surfaces by the mouse pad, the audio makes a pop noise and stops working. I then would have to turn off or put my laptop to sleep and the audio would return. However, any considerable pressure on the surfaces on the side of the mouse pad always causes this with always a pop noise. Something must be loose inside, but I don't exactly know how to identify what part is the audio hardware.

As well at times, the laptop detects no audio devices at all and I have to restart the PC. Basically I have to hold my laptop gently for any pressure causes the audio to cut off for both external and jack audio.

Laptop Information:

Here is a video I found of the internals where someone is replacing the hard disk; this may be useful:


I'm not sure whether or not this is hardware or software issue, since the audio comes back every time I turn my laptop off and back on.

Hello and welcome to PC Help Forum Coby,

What you describe would commonly suggest a system short and possibly caused by a loose or damaged track pad ribbon or speaker connection.

The following will not affect any possible warranty that may be in place as it does not involve opening up the notebook;

Suggests a hardware issue as mentioned above and for now must be put on hold before commenting.

This commonly concerns a driver issue so I suggest that you try starting the computer in Safe Mode only (no networking) see attachment below, try using the computer as you normally would, if the problem is still present then you are most likely looking at a hardware issue that will involve opening up the notebook.

Oops, missed the "no warranty" info :sleep:

The first troubleshooting screen shot suggests a software issue. You might try looking at the Device Manager, Sound- to see if there are yellow or red flags shown there. If so, please tell us what specifically they are.

Please try the notebook in Safe Mode only and use as you would normally as suggested then get back to us Coby, it may be totally coincidental that the audio comes back when the notebook is brought out of sleep and the fact that any pressure on the notebook knocks out the audio as Bill says suggests a hardware issue.

Can you also expand the Audio inputs and outputs tab in Device Manager then grab a screenshot and upload it for us.

Is it not expanded already? And I as well get the same results whether in safe mode or not. Audio going out with any pressure to that side and having to turn it off and back on to restore.

See the included attachment of your Device Manager and in particular what I have outlined in red, after watching your video and knowing the outcome of running in Safe Mode I am almost certain that this is a hardware issue but would like to make sure that we are thorough here.

Have come across system shorts caused by a notebooks housing before but never anything so sensitive as merely pressing the chassis :(

Will wait on the new screenshot for now.

No unknown devices there that could be causing a conflict which unfortunately means that I can only offer a couple more suggestions which I am sad to say I suspect will not help as they are software/settings related.
1: Go into the BIOS and restore the motherboards default factory settings.
2: Create a new system restore point, uninstall all of the present audio device in Device Manager, restart the computer and allow Windows to reinstall the devices then test.

Easiest solution if you don't want to spend money on repairs: attach a USB wireless mouse (that's the first thing I attach to all our netbooks) and turn off the touch pad.

Or borrow a mouse and see it turning off the touchpad keeps the sound going all the time.
