Compaq Evo N610c - USB on port replicator not working

I have a Compaq Evo N610C laptop - with issues

Call came in that wireless mouse and keyboard isn't working (I hate those things).  That device itself does as I've tested it elsewhere.  However, the USB ports on the port replicator aren't working.  So, obviously, I tried another port replicator - one I know works.  Still nothing.  The USB ports on the laptop itself work, so that is my temporary solution.

My boss says that this user had problems with this before and they replaced the MB in the laptop - which worked for about the last month.

Any thoughts?

Thanks for your help

I provide support for a large company and have ran accross this several times with the N610c and nc6000.  The port replators for these machines suck.  Sorry but it's the only word that accurately describes them.  First and foremost, you must update the BIOS.  This fixes several issues with these laptops.  Once that's done go into the Hardware Manager > USB Devices > Click on View > Hidden Devices > Remove all the hidden stuff.  Reboot.  The USB ports on those things are very buggy.  I've had at least 18 replaced under warranty in the past year and a half.  Hope this helps and BTW I feel your pain!
Well, if the laptop itself works OK (all ports) but port replicators don't, the problem may well sit in the port replicator connector on the laptop. This could be a physical problem (foreign matter in the connector) or a mobo problem.

I saw in another forum that the port replicator on the N610 doesn't go far enough in the dock port on the bottom of the laptop.  Any truth to that?

Now it's working just fine like nothing was ever wrong with it...Please be patient while I try to make it not work again...

I haven't had any problems with this since my last post, so I'm thinking it is resolved.  I have taken the steps that both of you recommended and it seems to have helped.

Thank you for your time.
