My keybad of hp 620 is not responding

keybad not keyboard. (the mouse pad or keyboard)
9year old laptop. it is.
no usb device plugged in right?
you turn on the PC, and it boots right?
and you see screens, what screen do you see?
the first screen (in most cases) is the windows login screen.
does that work ?
typing your login pass word?
then windows desktop arrives. and the mouse pad works?
and then keyboard works,
tell exactly what does not work.
and if typing, or tickling a mouse pad.
good luck.

My keyboard do not work at all.A little rain water got into it on the right side. Now the whole board do not work.

You probably need a new one. What probably happened when the rain water got on it was it might have hit an essential component that was on that side. Like the power cord maybe it short circuited the power cord and the thing doesn't work without power.

The USB ports have stopped working on my Dell inspiron 620, thus now I can't use my mouse or keyboard.How do I fix this problem?

Go to "Device Manager" and look if any yellow or red alerts are being displayed. You can get to "Device Manger" by clicking on your "Start" button, right click on "Computer" and select "Properties". It will be on the left side top of menu. If there are "Flags" click on them and see what the issue is. It might might be a corrupted software driver.
