http://ubuntuforums.org – My original answer to the question posed in the title would have been a resounding NO; but... after downloading the service manual for my Presario CQ62 lap top, I was surprised to find a magnetic screwdriver listed as one of the tools required for the component replacement procedures. Is that normal? It was my understanding that a magnetic tool should never be placed anywhere near computer components; is there actually a practical application for the use of one? Is it ever safe?
