R850/R840/R830

Additional memory module is a precision electronic component that may be fatally damaged by static electricity. Since the human body can carry static electricity, it is important that you discharge yourself before touching or installing any additional memory modules. To discharge your body’s static electricity, simply touch any metal close to you with bare hands.

Use a point size 1 Phillips screwdriver for R850/R840 and point size 0 Phillips screwdriver for R830 to remove and fasten the screws - the use of an incorrect screwdriver can damage the screw heads.
