External Speaker or Headphone Jack on the Panasonic Toughbook CF29 is located on the back side or rear of the CF29. There is a cover in the rear that has to first be opened. There is a sliding latch which has to be slid and held in rder to open the back cover.
Once the cover is open, then with the CF29 facing away from you as shown in the photo, the headphone jack is located on the left hand side. That is it!
Good Luck and Regards from:

you have to remove or unplug the cmos battery which is attached to the motherboard inside the laptop, doing this will clear all passwords. If the password clears replace the battery.
Here is some more usefull info if you want to this yourself>
The guts of the machine are usually under the keyboard. If you are okaywith opening up the laptop, you'll need to remove a few screws, thebattery and the hard drive, then carefully pry up the keyboard to gainaccess to the items that the manufacturers say you shouldn't tamperwith. If its just a matter of getting into the bios and theres apassword, you can usually simply remove the battery and leave itwithout power for at least 24hours, then it should reset....doesn'talways work but since most laptops actually do not have a standard cmosbattery, this would be one way to go about it. Of course you could justtry to figure out what the password is, someone has to have put it inthere so they should know what it is, or you could go to http://tcc.toughbook.com/ and get the bios update, which will reset it completely.
