Most users aren’t going to find that acceptable. Remove the battery pack. The header on mine is just labelled audio. I will be adding emphasis. It is recommended that you look at your motherboard manual. PC Card Test Error 1. This answers my question though, and gives me an idea what works.

On some motherboards it may be possible to disable the plug-in detection so they can work better though still not perfectly with an AC97 front panel.

I’m not sure of the exact different I assume that HD audio will gives better audio quality but I’ll always go for HD audio if the mainboard has it, if the mainboard only has AC97 then I’ll use AC97 connector. The cable looks somewhat like thiswith the AC 97 connector attached to the HD audio connector.

So if you plug a HDA front panel into an AC97 motherboard you will get no output on the rear audio output. Just to note, there’s a third kind of connector i came across, labelled azalia – which is a bundle of loose connectors. A full set of software drivers and utilities are available to allow advanced operating systems such as Windows and On HDA audio to the front and rear outputs comes from seperate outputs on the audio codec.


It will save battery power and prolong the A minor part of those standards is a front-panel audio connector. HD Audio is generally more capable.

They also have schemantics on pages 20 and 25 if you care. Your particular front panel looks to me like it is primerally designed for HD audio motherboards but with a hack to give limited support for AC97 boards. On AC97 audio to the rear audio output was looped by the front audio output and plugging in a device to the front panel audio output would electrically disconnect the rear audio output from the audio source.

Adding this as a comment in case someone comes across it.

Front panel audio design in conjunction with motherboard audio header design is dependant upon the type of audio CODEC being used on the motherboard. Mitaf header on the system itself is marked ‘Audio’. Remove eight screws M2L3 and lift up the Bracket. This answers my question though, and gives me an idea what works.

I would suggest trying the HD mirac connector first, if the rear audio output on your motherboard doesn’t work try using the AC97 connector instead. The pins that were previously used to loop back audio from the front are repurposed as connector-detect pins.


If you plug an AC97 front panel into a HDA motherboard then plugin detection will not work correctly, it may detect devices as kitac present when they are present and vice-versa and the exact results may depend on what audio is playing. For average home use, there shouldn’t really be a noticeable difference.

I’m currently setting up a older system in a new case i’ll be upgrading it in stages, and the old parts then go back into the old case ;pand i’m having a bit of confusion a9c7 which cable to use, and what the difference is.

The matching connector on your case should be labelled accordingly, I know mine is labelled HD Audio. However the connectors are only semi-compatible. Carefully put the notebook upside down. Remove two screws and disconnect the Modem cable form Carefully connected the keyboard cable to the Mother board, then put the keyboard into the housing well Step 2 Step 3 Reassemble Step: They both appear to have the same kind of connector right down to the ‘key’ – the space where there’s no pin and its filled upapparently the same colour codes at close inspection and so on.
