戴尔笔记本怎么选择开机光驱启动
您好将bios设置调成光盘启动的方法(不同机器可能有所不同)：
1、开机，并按住DEL键(不同机器有所不同，有些机器是按F2键)不放，直到出现BIOS设置的蓝色窗口；
2、将光标移动到（按↑、↓、←、→）“Advanced BIOS Features(高级BIOS功能设置)”，按Enter（回车）键，出现“Advanced BIOS Features”页面，一般分下面两种情况设置启动顺序：
⑴如果该页面有“First Boot Device(或1st Boot Device,第一启动设备)”、“Second Boot Device(或2nd Boot Device,第二启动设备)”、“Third Boot Device(或3rd Boot Device,第三启动设备)”，可以将光标移动到“First Boot Device”项，按Page up或Page down键将其调节为CD-ROM，按ESC键退出该页面，再选择“Save& Exit Setup(存储并退出)"，回车，按Y键，回车即可。
⑵如果该页面有“Boot Device Select...(启动设备选择)”，请将光标移动到“Boot Device Select...”，按Enter（回车）键，出现一个小窗口，里面有“1st(或First)”“2nd(或Second)”“3rd(或Third)”三项，将光标移动到“1st(或First)”，按Page up或Page down键将其调节为CD-ROM，按ESC键退出该窗口，再按ESC键退出“Advanced BIOS Features”，再选择“Save& Exit Setup(存储并退出)"，回车，按Y键，回车即可。

求推荐3500-4100的大学生用笔记本电脑
我整理了下，没有详细罗列参数，因为觉得没意义，结合了自己网上看的测评和自己的一些看法写了我推荐的理由，感觉这样才更直观..希望你满意.
1首推宏基4752：I5的cpu+GT630的显卡..这个算无敌的性价比了...（宏基V3系列和它相同的显卡和CPU贵个800左右），这个价格这种配置做工别指望太好，但是撑个几年绝对没问题...而且多种颜色的拉丝外壳，非常漂亮;；
2华硕A43EI245SJ-SL 14.0英寸笔记本电脑：（i5-2450 4G 320G 1G独显 USB3.0）缺点是用的是GT610的显卡，是NVIDIA新平台的最烂的显卡，性价比一般，但是要考虑到华硕的品牌价值，喜欢华硕的可以买~可以满足一般的用途，不玩游戏的话~
3戴尔Ins15R-958R：15英寸笔记本电脑i3-2350M 4G 500G GT525M外观很漂亮，红色，给人感觉很活泼，配置如上，GT525的显卡介于GT610和GT620之间，性价比自然是不如宏基的，不过亮点在15英寸，散热做工也不错，不玩大游戏的人可以考虑入手。
4.联想B480..先不要管这款黑不溜秋长得像飞机失事的黑匣子一样难看的外观啊，配置是NB的 I5+GT630有木有啊，淘宝商城的价格才3500，便宜到几乎和神舟一个价格有木有啊，联想良心了一会有木有啊..喜欢联想有想要性价比的现在就可以上了...时不我待!!
6另外这个价位不推荐联想的Think pad系列，举个例子，Thinkpad E420价格是3500，但是用的显卡却是最烂的，而且做工也没看出多好，完全没有做出TP系列该有的样子，TP的精髓在7K元以上的系列，（W520）另外为什么不推荐性价比高的吓人的神舟系列呢..因为，神舟我只推荐精盾系列，而这个价位只能买到神舟优雅系列，优雅系列的做工真心实在不敢恭维。
