NOTE: If you need to type in a password to even get into Windows to do the following, make sure you attached an external keyboard first, to get past the password. Then disconnect the external keyboard and try the following...

1. Uninstall the keyboard driver.
2. Reboot the computer (without reinstalling the driver).
3. When it restarts, it should reinstall the driver on its own.

If this doesn't work, you may wish to try connecting an external keyboard and see if it works fine. If it does, then it could be the keys themselves that are the issue.

You may also want to try updating the Synaptics Driver if the above doesn't help.

Some things to try if your touchscreen doesn't work...

1. Restart the computer. Sometimes that is all that it needs.

2. Wipe off the display with a soft, clean cloth. Yes, sometimes it is just that.

3. Go to "Start" and in the search box type "Calibrate the screen for pen or touch input". Choose the top result. In this new screen click "Setup" and follow the instructions.

4. Go to "Control Panel" and then "Device Manager". Select the "Monitors" section and right click on your monitor. Check the information for the touch screen and make sure it is "enabled".

5. Repeat step 4, but instead choose "Update driver software" from the right-click menu.
