Re: bad solder on a/c power socket of pc board.
This link will take you to a disassembly guide. http://www.irisvista.com/tech/laptops/Toshiba_Satellite_M35/take_apart_notebook_1.htm Is that what you're looking for?

Hi, If your asking for schematics you're a little knowledgeable-which is good. Rarely have I seen " headphone jacks " go bad. Usually the solder joints on the circuit board are a little bit cold soldered ( instead of a nice shining silver color to the connection-a dull frosted appearance) they may even have pulled away from the board a bit. So disassembling the unit ( power off of course ) and checking this ( jewelers loupe or magnifying glass of equivalence recommended) may be all that is required. I hope this was helpful, If so please don't forget to comment back to let us know how we did. Good luck and thanks for asking FixYa, Prodzilla
Good day, Are talking bout the PS/2 keyboard (the one with rounded plug)? The socket for this type of keyboard is soldered in the board. The more usual problem is that the pins of the socket is teared off the board, and needs to be soldered again. You may disassembled the board from your casing and solder the keyboard socket. Just do it carefully not to burned the board and the other circuitry. Needs more help - just post again here at Fixya. Good luck.
Looks like either the power jack of your adapter is experiencing a bad connection. Check if the power adapter's cable near the jack which plugs into the laptop is not severely bent.If this is the case, then you will need to replace the power adapter.
If this is not the case, check the DC socket where you plug the power jack into the laptop. This socket might be loose or broken. If this turns out to be the case, then your laptop needs to be disassembled in order to re-solder or replace this socket, depending on its condition.
If you are comfortable with working in tv circuit boards then unplug tv from AC wall socket, take off back of tv and follow AC cord going inside tv that will take you to power supply board, check fuse on power supply board, replace it with same rating written on it if it found blown. Replug tv back in wall socket and check if it turns On. If still problem not solved then power supply board is defective and need to be replaced. Local tv repair shop will help you if you think its not safe for you to work inside tv. Hope these info will help you. Thanks.
Use epoxy glue to fasten the socket to the board. I assume that you have a proper soldering iron (small grounded tip, not a soldering gun), and know how to use it. After the epoxy has cured, trace the damaged tracks back to another solder connection, then solder an insulated (about #24 or #26) wire to that point and to the appropriate connection on the power jack. There should be a maximum of three wires to install. If you make the proper connections, it should work as before. Good luck!
There is no quick fix other than tapping or glueing it into a position that works. This is not a permanent fix and will fail again sometime.
The laptop power connector is either loose or faulty, the laptop needs to be dismantled to access the plug to resolder it (if loose) or replaced if faulty.
Reheat all the surface mount solder points on the Small Signal Board. Then realign the set
including convergence menu. To enter service mode: power off the set
for 10 sec, then hold down Vol- and Ch- buttons for 10 sec.

Wow Buddy. I'm impressed with your work here.
I have seen many boards which were oem, which had what appeared to be 'add on' circuitry. It's common when a problem arises in a product, which they've already had a million of manufactured. Otherwise, maybe the NSA, CIA, or MA Bell doing a little snooping?
Ok just kidding.
Assuming the circuitry which was replaced was still there, I've experienced a couple of "no power" issues on these models.
Bad power board.
AC adapter socket unsoldered from board.
Dead short between motherboard and palmrest/case.
Best thing since it's apart already, just order another board and you'r good to go.
I sell the same board at my shop for 75-100.00 US.
If the processor's good, then you should be good to go.
First pulling a machine apart takes time and careful disassembly - it is easy to snap off fragile plastic panels or rip cables and replacement parts can easily cost as much as paying someone to disassemble it for you. Usually a jack repair is $100-$150 depending on the shop.
Toshiba's are a multilayered setup - You have to remove all the screws from the bottom (note that they are labeled by screw length next to each hole - do NOT put the wrong length in when reassembling!!) Make sure to remove the hard drive and ram cover and check for screws there are well.
After all the screws are out of the bottom, remove the panel above the keyboard. Remove the keyboard and all the screws under the keyboard. Then you can get at the motherboard and power jack.
You will probably have to remove the motherboard to replace the jack - Usually the mounting screws for the motherboard are not so clearly labeled - i mark the holes with a sharpie when pulling a mainboard.
