The headphones on my Tosiba Satellite Pro A200 dont work

Have you tried another Cord with the EXACT same power specs? Remove the battery. Has the cord/charger/transformer been damaged? Has the AC jack been damaged? Due to pulling on the cord while plugged in? At the AC jack "wiggle" the plug a bit to see if the plug and AC jack are making a good connection or Loose. Sounds like a loose AC connection.

Hi,
for removing the password,

you have to open the memory cover and remove the two RAM s,
after that remove a black or whit plastic film depending on your model, you will loacte for B500 marqued ( XXX ) or J1 you have at least short
the two point with a flat screwdriver and put the upper memory and power on the laptop will holding the screew driver till you see the toshiba screen, if it doen't work just try again. it works 100%

overheat, overload,voltage fluctuations

It sounds like the connector from the A/C adapter to the motherboard is loose or the inside of the adapter plug that attaches to the motherboard is defective.

I have seen this many times and found bad solder joints on the motherboard on the bottom side of the headphone jack. I have also seen the plug coming from the speakers to the motherboard lose. If you feel this is too much for you to handle then you need to go to a PC shop or a friend that can solder PC boards. Good luck! Phil

P.S. This is not a software issue for certain.

Unfortunately, if you can't remember your bios password you'll have to reset the CMOS. This is usually done via a jumper on your laptops motherboard itself, or removing the battery on the motherboard while the laptop is unplugged and the main battery is taken out. Be very careful when opening up your laptop, make sure all the screws needed are removed, as they are easy to miss. If you don't feel comfortable opening up your laptop, I would recommend taking it to a certified technician.

GO INTO CONTROL PANAL GO TO SOUND OPEN FOLDER GO TO SOUND TAB AND FIND WHAT ITEM YOU ARE HAVINGISSUES WITH HIGHLIGHT IT AND TEST IT TO.

DEVICE MANAGER IN CONTROL PANAL, CHECK THE DEVICE AND IT DRIVER AND ANY NEW UPDATES

Check your sound device levels. you may need to enable that headphone port before it is usable. you can do this in the control panel tab. reinstalling your sound drivers wouldn't hurt also.

HAHA i had the same problem so here is what i did...i stuck a head phone plug in the jack and smacked it a couple times and bam it works....i would suggest doing this if your lazy otherwise go to the apple store because obviously somthings not right in your laptop.

Not unless you know how to work on a headphone jack and how the jack and the jack switchs work??? Also if you dont know about the HI Voltage saftey issues, it would be best for you to bring this set to a pro tech, as it shouldnt cost to much for a new headphone jack??. Good Luck
