Make sure the plug wiring is the correct polarity and of course the plug itself must be the right type. Mark Z. |

IME these laptop adapters are rarely spot on anyway. After all, they are calibrated by human beings so a 0.5V error is hardly going to be critical. Also, over years of use they will probably drift by that amount anyway. This voltage feeds regulated switchmode power supplies inside the laptop, so it doesn't have to be deadly accurate. The CPU, chipset, hard drive etc will still get exactly the right voltage. Dave |
