CF-29 Mk4 no sound

Hello everyone, I have a Panasonic CF-29 MK4 L3L GZBM Toughbook; 1.60GHz; 2048 MB system memory; 320 GB Prymary master, bought in the US a few years ago, Windows XP sp3 Os.
Since there are no more 'updates of XP I have bought a new disk IDE / PATA 320 GB and install INDOWS 7. Unfortunately I had no more sound, so I replaced the new Primary with the old one. Again I no longer had the sound, I reinstalled the original drivers (from device manager everything is 'ok), I removed the original speaker by connecting it to an' other pc and it works but I do not hear from the headphone; another thing, the optical CD / DVD reader,read only disks in Word, ppt pdf etc, if I introduce a music disc , the reader doesen't read. Any suggestion is welcome Thanks Cesar

 

A power pull re-set is indicated.
To eliminate scrambled mother-board:
Pull all power.
Hold switch on for a few 15-30 second cycles.
Plug in power supply. (no battery yet)
Set bios to defaults and save [F2][F9][F10]
Re-start and install battery.

 

Not clear about headphones. Do they work when plugged in?

 

Try using another music program

 

Could this be one where the headset jack switch is jammed?
It is inside the jack. Strong light, thin probe ....pull all power first.

 

There seems to be a relationship between Vista and W7. While looking around I found this in CF-29 drivers jp.....(note: install, un-install, install)

For what it's worth,

J'd...good luck...

 

I have done all this but it doesen't work

 

I have followed all this step by step but it is the same as before

 

Not working

 

What I would do is start all over and install XP Pro and forget about W7 . It does not run good on a CF-29 at all . Been there...done that...not going there again

 

Do you have a Linux Live CD?
