Hi Ed,

Well, this is Science Electronics Repair - so a computer covers all the 
bases, I'd say this was on-topic.

When the computer shuts down, does the screen go blank and the fan(s) 
stop spinning? Does the Caps Lock key not display the LED to say it has 
been or can be toggled on/off? If the caps lock still toggles then it 
may be a screen backlight issue, especially if the fan(s) still spin. 
Try playing some music when the computer is working and check if the 
music stops when the screen goes blank. If music still plays then pretty 
safe bet the screen has issues.

Otherwise, as suggested, dust may be the problem, or the switching power 
supply's electrolytic capacitors may have reached their end-of-life and 
either need new caps or a new switching supply. May not be so easy to 
fix the power supply on a laptop...
