http://support.dell.com/support/edocs/systems/xpsM1530/en/SM/index.htm ]Handle the Ram Memory module by the BODY.The Body is everywhere on the Ram Memory module, EXCEPT the gold plated contact pins on the bottom.The Body is coated with a see-through protective plastic,
http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.pngUse a pencil eraser to clean the contact pins. ALL pins, BOTH sides.If you are using a pencil eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band of the pencil, touch the gold plated contact pins.Rub up, and down on each contact pin. Doesn't take much pressure, nor rubbing to clean them.In fact when you are done the contact pins may not be bright, and shiny.It's okay I assure you that you have cleaned them.(Doesn't take much 'corrosion' to make a bad contact surface)Use air to remove the eraser dust. If you have a can if compressed air available use it. (Also use on the ram memory slots)If not air pressure from your mouth will be sufficient.Reinstall all Ram Memory modules. Reinstall the Battery, and then plug the AC adapter in. (Then plug the AC adapter into power)WAIT 1 minute, turn the laptop on.For additional questions please post in a Comment.Regards,joecoolvette
