Can I use any power lead to run a laptop ?

Can you unplug the lead that is plugged into the charger? if you can, this can be replaced by a 230/240 volt lead, it has a three pin plug at one end that plugs into the wall socket, the other end has a female socket that has two round holes that plug into the charger, the charger converts the 240 volt A/C current to the required D/C current that powers your Laptop, provided that the charger is working OK, you only need to replace the power lead that plugs into the wall but Amazon sell the complete charger and power cord for �14 plus postage and packaging.
