My panasonic cf-52 speakers doesn't work, but when i put a headphones it works properly, is that meen i have to replace the speakers?

I had a similar situation with my CF-53. Oddly, the speakers would not work, but headphones plugged into the port on the front of the laptop would. Could you verify that you get audio through the headphone port, please?

When you swapped out the Hard Disk Drive
of the Panasonic Toughbook CF52 it is very
importatnt that you did not "hot" swap the HDD
but that you turned off the unit with a full shutdown
and unplugged it as well.

Once you removed the Hard Disk Drive (HDD)
I am assuming that you replaced the drive with
another drive that had a proper operating system
already installed. If not, then of course nothing
happened since you replaced the HDD with a blank
or unformatted HDD.

One way to verify if the replacement Hard Drive
is recognized by the Toughbook is to go into
the BIOS by pressing the F2 function key and
checking the size or capacity of the replacement
Hard Disk Drive. If it shows the proper value,
then the HDD is recognized at the Hardware Level.

If it shows HDD as None or Zero then the replacement
HDD is NOT recognized and you have to try a different
drive which is functional.

Good Luck!

1) you must the headphones in any radio, for to see if the problem they are.

2) if they are o.k go control panel use the utility system restore put the last date that you know that was working.

God bless you

Have you tried rebooting? In the Control Panel, select Sounds, select Speakers as default, remove headphones plug from jack.

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!
