I have always found some difficulties in connecting my S5830i to my laptop through Kies. Most times Kies does nothing until I troubleshoot the connection and then reconnect the cable. Sometimes the phone is then recognised and sometimes it isn't.
I have recently purchased a new Windows 8.1 64 bit laptop and downloaded Kies to it afresh. I initially managed to connect my phone straight away but now, several days later, I am getting absolutely no recognition of the phone at all. The phone is charging OK from the laptop connection, but I cannot see the phone, either through Kies or by using File Explorer.

Anyone got any ideas please?
