power-supply

My original laptop adapter broke down, so I've baught a new one. It's a no-brand adapter from a dutch internet shop.

The power of the new adapter is slightly more than the old adapter, but in my opinion that shouldn't be a problem.

The laptop is a Toshiba Sattelite L40-15B. When the old adapter broke down due to short circuit, this laptop was connected.

When the adapter is unplugged, the touchpad works correctly and smoothly. But as soon as it is connected, the cursor moves jumpy, and response badly.

Does anyone know where this problem comes from, and if there's a solution?
