Question about Computers & Internet
If you leave the old type NiCad batteries on charge all of the time, they will barely last a year. Run the battery down at least once a month.

your battery cells are dying to over charging coz its system is similar to that of a cell phone, but in future you will need to buy an extra battery.

Testimonial: "Thank you for your advice. May be in the future I should unplug the computer from the mains and let it run on the battery on a regular basis. Thanks"
Did you press the FN hold it down and do the brightness? If you did then you need a new keyboard replacement. John

SOURCE: SAMSUNG NP R430 POWER JACK
There is something seriously wrong with the power jack for it to get very hot. I doubt replacing the power jack will fix this problem. The laptop needs to be repaired by a specialist.

When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.
