I bought a Dell Inspiron N7010 laptop with windows 7 home premium in 2011. I have ran a few online scans from dell, but my laptop passed every test,   but   , When typing with the keyboard, whenever i use the caps button to go from caps to lowercase or vice-aversa, the cursor disappears for a few seconds, then hangs, then re-appears after a few seconds pass. Sometimes i have to use the mouse to make the cursor re-appear in the specific place to carry on typing after changing. Is there any solution for this problem as its driving me crazy. thanks guys.
