Question about Toshiba Satellite P15-S479 Notebook
DC power connector on laptop has bad solder joint? Must apply upward pressure on the power connector for operation. Problem is not the DC supply side.
How do I safely open the back of the PC to inspect?. If it is a bad solder joint I am qualified to repair.
This website may help you with the disassembly/reassembly.
I've done a number of these repairs, but not on Toshiba's.
When the power connector becomes loose it can cause over heating which can damage the system board. On a couple of the laptops I fixed the damage was so bad that I did not replace the connector. Instead, I soldered wire and made a "pigtail" by using a female connector I purchased that mated with the power supply. I put shrinkwrap over the wire and zip tied the connector to the back of the laptop. It's not as pretty as the original solution, but it takes all the stress off the system board.

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.
