Stereo shuts off at 69

Most of these sets have a very small audio output and connecting larger speakers will just lower the volume---if it is tinny at high volume or rattles better to upgrade to another set.

Generally speaking, sub-woofers are not built into notebook computers, as most sub-woofers would not fit. However, there are generally speakers, and there tend to be problems with the audio drivers in most cases if there is no sound for both speakers and headphones.
Within the notebook, there should only be two speakers. If they're missing, did you buy this used or refurbished? If someone just yanked out the two speakers and carelessly cut or handled the wiring improperly, then this could interrupt the headphone bypass cut-off.
I know you mentioned you'd already verified everything appeared to be working properly, and in some cases updating drivers or uninstalling and re-installing them has a positive result. For the obvious, which I've also forgotten to check sometimes, is whether the output is muted within the volume control and mixer.
In case you hadn't already checked out these, here are a few links you may find useful:http://h10032.www1.hp.com/ctg/Manual/c01613382.pdf

As always, the more complete the information up front, the better the potential for a solution. I hope this helps!

Hi,

In bridge mode the minimum load will be 8 Ohm.
If you are using 4 Ohm speakers, it will mean you will give each side of the amplifier a 2 Ohm load.
Thats to much for this model.

Kind regards,

Hi,

Try less speakers.
The impedance will be to low for this amp.

you cant remove the overload light. it does that as a safty so you dont burn up the amp when its not being used properly. do u have a capacitor? are the speakers ohms and watts the same as the amp?

are the hooked up correctly positive and negative whats the ohm load of the speakers and amp could be a short in your speaker cables
could be many different problems

Does your tv have stereo outputs? if yes all you have to do is run RCA red..white jacks into tv outtput then run the other ends into the amps tape or aux or cd input and your done! If you dont have outputs on tour tv you will have to but an RF converter box (about 20.00 at wal-mart) and hook that into the tv and the cables will run out of that to the stereo!

I assume you have told Windows about you new speakers ???
(Start, Settings, Control Panel, Sounds and Audio Devices = Volume tab, Speaker Settings box, Advanced button ...)

shut down all electrical sets around and check if the static goen the problem will be in electrical sets and you have to check it one by one.if it is not solved check your cables for any bad connector -open circuit- short circuit(try with a couple of new cables).-apply a contact cleaner in all sockets and move jack in and out in all sockets(with no power on)

this probably isnt it but my stereo got messed up like that because i think i turned it up and down way to much. maybe try pulling the volume button out and putting it back in.
