what? is that all you can come up with? blow it out with some compressed air!
i was expecting something along the lines of cleaning it out, tightening it up so it grips the usb plug or something more than blow some air up its ass!
i am feeling that i have had smoke blown up my ass by justanswer.
no there are not many programmes running just office and that is 1 application at a time.
i plug in the usb mouse, pointer or memory stick in the port and it takes time to recognise it. i think it is because the ports are old or dirty.
with other electrical connections you can re-sensitise them by getting back to bare metal or refreshing the connections etc.
just the same
maybe i will sing it a song too!
