Hi everyone this is my first post for some much needed help.

I have a Fujitsu Siemens Amilo Laptop with a big problem, the laptop will not power up via the power supply it will only power up from the battery. I have also noticed the metal prong which inserts into the laptop via the charger gets very very hot. The battery does not charge either !!!!!!

:!:

Help !!!!

Quick summary for and follow-ups to and : an adapter that gets very hot at the metal prong and will not power the laptop (while the battery will) is a potential safety hazard and calls for a short, high-resistance connection, or a failing adapter/charging path. Before buying parts, do a few safe, simple checks to narrow the fault.

  • Safety first: unplug the adapter and stop using it if the plug or cable is hot, melted, or smells burned. Overheating chargers can cause fires.
  • Visual check: inspect the barrel plug, cable, and adapter box for cracks, exposed wires, or a loose center pin.
  • Measure the adapter: with a DC multimeter set to VDC, read the adapter output (red probe to inner pin, black to outer sleeve). Compare to the voltage on the adapter label. No/low voltage = bad adapter. Take care not to short the plug.
  • Isolate the laptop: remove the battery and try to power the machine with a known-good adapter of the same voltage/polarity and equal-or-higher current rating. If the laptop still will not power on, suspect the DC jack or internal charging circuit. If it works, the adapter was the issue or the original battery/charging path is faulty.
  • Check the jack: a loose or damaged DC jack can create high resistance and heat at the plug. If the jack wiggles, it often needs repair or board-level work.

If the adapter fails the meter test or shows internal heat under light load, replace it with an OEM or high-quality compatible unit that matches voltage and polarity. Do not use adapters with incorrect voltage. Board-level fixes (fuses, MOSFETs, jack replacement) require experience or a repair shop. If unsure, stop using the hot adapter and seek qualified service.

looks like u need to get another power supply. cos if the system is turning up from the battery and not with the power supply then the fault point towards the port on the notebook and the port on the powersupply, now again u say that the ac adapter is getting abnormally hot , so i belive that its time to replace the power if u have any other power supply with ur friends or any one try using that and check out.:)

Probably unrelated but Dell is recalling 4 million laptop ac adapters...

Many times different manufacturers use the same components.

You might google it just to see if it looks the same as the recalled power supplies.
