Power socket loose connection most likely. Disasemble laptop take out the motherboard and check the conections of the power socket, replace the power socket if needed. You need fine soldering tool.

Bad cord/charger, bad battery? What give you the idea that " i think it has a broken internal power supply" Your saying your laptop will not charge the battery? Does the laptop work? If so the power supply is OK.
There are two supply systems are in your machines. One is for charging the battery, and other is for bypass AC power converted to Dc ; when AC power is present. That is when AC power is present, your machine will work on that power, and charge the battery simoultaneously. When AC power is inturupted, it will automaticaly change over to battery power. But the power consumtion of your machine is high. Therefore battery power will get downed soon. Battery is placed inside the machne only for urgent power faulure use. Not for continous use. Both the power supplies are SMPS [Switched Mode Power Supply] types. We can't prophet the reason for its failure. We are repairing such machens here. Now your machines battery charging circuit is ok. AC power bypass is faulty.

Try changing out the battery with a new one and see if it charges since the power supply is working because its charging. If a new battery doesn't work then the motherboard is bad and would need to be replaced.
1. the adapter may be ok but the unit battery that the adapter is charging may have a bad cell and not taking the charge or the power connector may need replacement . Only a qualified tech can determine this by doing electrical checks with a meter and or diagnostic instrument. Take your unit to a tech to do a diagnostic. More than likely it is the battery.
sounds like your charging circuit isn't working or the adapter isn't putting out enough power or amprage to fully charge the battery, or you battery went bad. if the charging circuit is bad then so is *********** board, time to burry the system and buy a new one
check that the power supply is the correct one for the laptop, check that the power requirements of the laptop match up with what is being supplied by the power supply. if the labels match, for Toshiba the usual supply voltage is 15VDC, if the supplied voltage is 1 volt below recommended the battery will not charge. If all appears correct then check the output voltage with a multimeter it should read 15V (-0.25V +1V). If the power supply is a bit low you'll need to buy a new or used one.
It is possible you have two dud batteries. Recharageable batteries have a limited life, they have a finite number of charge and discharge cycles.
With the battery removed and only the power supply connected and the laptop powered up, when you touch the connector on the laptop and the laptop does not shut down then the laptop connector is OK.
If you can verify your new battery is OK the the fault could be the power supply adapter, if may not produce enought current to run and charge the battery. Try charging the battery overnight by turning off the laptop and leaving on the mains t charge. Borrow a mains adapter and test it on your computer.
You can also check the BIOS setting for power management, ie. hibernate, low power shut down etc.
if u have a multimeter do check the output of the power supply for the voltage if it is ok then check the battery and check the supply is coming to the battery point to charge it if not the charging ic is defective do check that
