Try to remove the battery and turn the computer on with only the AC adapter connected. If it works then you have to replace your battery. It it does not, then you will need to replace your laptop because you have a faulty motherboard, and replacing your motherboard would cost a lot. almost like replacing your computer already.
Please remove the Ac power supply and BATTERY. then press the power button and hold for 10-15 seconds. Then connect the ac adapter to the laptop and turn on laptop WITHOUT battery. Check whether the laptop is on. If ON , shutdown the laptop and remove the ac adapter and then instert the battery in laptop. and give the ac power supply and use it.
Hope this helps you .
Try removing the battery completely and running it with the power supply connected. If that doesn't work, try borrowing a compatible power supply, or buy a universal one, and try with and without the battery connected. The problem may be the power supply, in which case the battery won't charge and the laptop won't get any power.
Replace the AC Adapter, (ebay from £10.00). Did it come with XP on it? Mine came with Vista and there are conflicts with XP and graphic adapters. There is no XP driver for the ATI adapter in mine. Go online to Toshiba and download all of the updated drivers that you require. A user friendly system.
How about this step, try to turn off the laptop itself. Remove the cables and battery just like what you did before, then press and hold the power button for 10 seconds. Then, reinsert the cables and battery on the laptop and then turn on the computer itself. If the laptop restarts, shuts down or freezes with the AC power cables, two things that you should seriously consider. It might be the power cable itself, AC cable port or the circuitry going to the motherboard. And since you have cleaned out the fan and heat sink, you have isolated that problem. Have you plug-in another power cable on your laptop? If yes, then check if it works. Otherwise, the main issue is that the AC port is loose or the circuitry of AC adapter going to the motherboard is not not working. You can re-open the unit and check the circuitry from the AC port going to the motherboard. You may check the circuitry from AC port to the power supply if it is ok. If symptom persist, please contact your local dealer...
try to power drain the computer,removed the battery and unplugged the ac adapter then while the computer is off,press and hold the power button for at least one minute,then connect the laptop directly to the power outlet without using the battery then turn it on,if still the same,contact manufacturer of the laptop for LCD replacement or LCD cable replacement
