Dell inspiron laptop keyboard problem keys stop working

Hi ,

try check ur keyboard in different applications like word, notepad and ur email...check if the keyboard keys are working or not...if no go...restart the system keep tapping F8 while its boots..select the option safe mode and check in the safe mode if the keyboard works or not...if still no go...u have to reseat the keyboard and its very easy.... check this link http://tinyurl.com/yfbyqu
Reseat the keyboard and before doing that u have to remove the hinge cover also..check the above website how to do that...So finaly even after reseating the keyboard if the keys doesnt work then the keyboard has to be replaced.
