HOW DO YOU SET THE TIME BEFORE SCREEN TIMES OUT WHEN KEYBOARD NOT TOUCHED

restart it and see

I assume you have a touch screen? but the keyboard seems to be the problem..(sticky keys) so might try a different keyboard and it wouldn't hurt to clean the Touch screen with an approved cleaner

I think what has been done is your grandchild has accidently magnified your screen slightly. To correct this hold down your ctrl key on your keyboard and move your finger on the mouse scroll button back. Hope this helps.

Check if the screen saver is set to come on at 90 minutes, and the VGA cable, is tightly connected at both ends, if so, it might be a virus, check your virus detecting software,

Your problem sounds more like the system running slow rather than the keyboard being the issue.
Do routine maintenance and cleanup on your system to see if it helps it.

To start the Disk Cleanup tool and specify the hard disk to clean by using a command line, use the following steps:

1. Click Start, and then click Run.
2. In the Open box, type the following line and then press ENTER
   cleanmgr
3. click OK
4. The dialog box that opens shows you the files it will remove to clean up the system
5. Make sure Temporary files is checked
6. Click OK
   

Then check your system for malicious software.

1. Go to http://malwarebytes.org
2. Download and scan the system
3. Remove all found infections.
4. Restart your system

These things should help if this is the cause.
If your problem still is present, change the battery in the keyboard. A battery that is close to empty will cause this as well.

Let me know if this resolves your issue.

it's probably not the LCD, it is most likely the ribbon cable... it could be repaired or if not, replaced...

I never used the leopard software but there is a control panel in the OS the allows you to customize your keyboard ( example set the windows key as the apple key ) i maybe wrong though because i havent touched an apple in years. http://www.apple.com/macosx/

try cleaning the touch screen glass between the glass and the frame, if that fails, you need to replace the touchscreen glass
