Hello, I have an HP Probook 645 G1 and I need to remove the internal plastic cover to access the motherboard. This plastic cover is attached with what appear to be torx screws and the printed on the cover, where each screw is located is the indication that these are 'M2.5' screws eg. 'M2.5x4' - suggesting to me M2.5 screw heads. - See the attached photo. Can someone clarify what type of M2.5 screw driver i need to remove these? I looked at Torx screw drivers but they all appear to be larger 'Txx' sizes. A browse of some online retailers (eg. RS components and Maplin) does not make it obvious what screwdriver type i should purchase. Thanks, James. [ATTACH=full]235[/ATTACH]
