Re: DS2501

DS2501 is NOT a transistor, it's a programmable memory device. The device is pre-programmed with power adapter specific details,like wattage,current etc.

If you bought a DS2501 you would also need a programming tool to feed the device with the necessary information......


In most cases it's not the DS2501 that failed - it is more likely that the power adapter cable that connects to the power jack or the power jack itself is broken.
