Re: Inspiron 2600 External Mouse problem
Have you tried an external keyboard in addition to the external mice? It is important to know that, unlike USB ports, PS/2 ports are not designed to accept connection to external devices while powered up. Whenever connecting a PS/2, parallel, serial or external video device, the system should not be powered up. Connecting these types of devices while the system is powered up can damage the port.
If the PS/2 port is not functional, you can use a USB mouse or a PS/2 to USB adapter and connect to a USB port.
