I have a late 2008 Macbook Pro all aluminum.

The green caps lock light comes on intermittently: sometimes solid, sometimes flashing. When it comes on, the arrow pointer gets stuck and the screen freezes, or if I'm typing it will stick on a letter and keep repeating it.

Any ideas? …or is it a keyboard replacement?

Try an external usb or wireless keyboard. If it works ok, then most likely you internal keyboard is damaged and needs repair or replacement.


You could try blasting the dirt from under it (accumulated over Years) with a dust can available in computer stores.

If you feel like a DIY then look here for instructions how to replace keyboard.
