宫雨任1346联想一体机3000 c100 怎么拆装 -
符蓓霞18239225683 ______ 您好,如果您对笔记本的结构不是很了解,不建议自行拆装可能会由于误操作对硬件造成损伤,您可以联系服务站在工程师的帮助下拆装一体机,对您以后的使用也有保证.感谢您对联想产品的支持,祝您愉快

宫雨任1346佳能EOS C100真的好用吗 -
符蓓霞18239225683 ______ C100使用的就是佳能单反所使用的EF镜头,当然佳能也有专门为摄像设计的电影镜头,只要是EF卡口的都可以用.一般来说摄影镜头和摄像镜头还是有差别的,摄影镜头强调分辨率锐度,摄像镜头可能更强调反差色彩,另外大光圈效果也好一些.好的专业摄像镜头挺贵的,如果你不是专业摄像就不必花这个钱了,佳能单反镜头可以兼顾摄像,只要是EF口镜头都可用在C100上,包括你说的那些镜头.

宫雨任1346联想C100一体机想玩些3D游戏改换那些配置 -
符蓓霞18239225683 ______ 凌动(Atom)的芯片定位为家庭一般办公及上网用途,向这款机器几乎玩不了什么高级的3D游戏,而且一体机的话配件也几乎更换不了什么,唯一能做的就是将内存增加为4GB.但是,Atom芯片对内存容量的支持不高,且集成的Intel GMA950芯片也仅能支持一些中低端的3D游戏.个人认为,此机器无升级的必要.
