Title: laptop keyboard works only part time
Post by: btb57 on November 30, 2009, 04:28:36 PM

I am facing a challenging problem. my laptop's keyboard works when the computer starts, but then it will stop working when the computer resumes from sleep or hibernation.

it does work to bring the computer out of sleep mode, but I cannot type my password at the welcome screen.

I also noticed that I cannot get to setup config during system startup because the keyboard isn't working then.

I am running Windows Vista SP1 on a compaq presario cq50-115NR


Any help will be appreciated!

Try using a PnP (Plug-and-Play) keyboard.  Boot up and use that keyboard to check your settings in control panel.  Also, check to make sure there's no driver issues in device manager.  If there isn't, uninstall your keyboard driver then right-click and "search for new drivers" and let windows install a fresh one.

While you're at it, run a Virus scan if you have one.

I fixed the problem by removing the keyboard and then reattaching it.
