Keyboard USB and touchpad issues

I have seen several complaints online about keyboard USB and touchpad dropping out and becoming unusable. Would this be a motherboard issue?

I had a feeling that would be the problem... First I lost one USB port, then the other 2, and then all of a sudden lost keyboard and mouse... can't get into BIOS, can't change screen to show on our plasma display only, because no keyboard shortcuts work for the laptop. However, I can use an external USB PCMCIA card and then plug in external mouse and keyboard, but this is a pain for a laptop.

Somehow I do not think that the USB PCMCIA solution will be permanent. It sounds like you are going to have further failure on your board. I suppose its time to replace it....

If they are out before the operating system loads then yes it is a motherboard issue. If the problem doesn't show itself till the operating system is loaded it could also be driver issues or a corrupt registry. The easiest way to eliminate them is to back up your data and do a system recovery, not a restore. Those either have a recovery partition on the hard drive or came with recovery disks. This will put the operating system back to the way it was when originally purchased. Basically it amounts to formatting the hard drive, then reinstalling the operating system and drivers. If that doesn't solve the problem then the issue is on the motherboard. If only a couple of these are not working then more than likely the USB power MOFETs have been compromised. If they are all out then the chances are the southbridge has BGA issues.
