今天是一年一度的端午节
额 自己没什么感觉
说什么粽子啊粽子的
只是说说而已了 没得吃- -：（
到超市买粽子
只有那种微波炉烤的
然后结账的时候突然发觉没有微波炉
只好无奈的放回
哎 人生啊

自己一个人住了以后觉得很安静
自己想干什么就干什么
但是久了也觉得不爽
没人说话
房东那一家人都可冷淡
除了付房租的时候笑笑
其他时候基本把我当不存在
哎 人生啊

发现自己貌似被隔离了
除了学习睡觉吃饭别的啥都不干
平庸的过着
不过将来工作后也是这样吧
自己一个人而已
╮(╯▽╰)╭

目前对PHPh和MYSQL是相当的感兴趣
整了这么多天终于整到自己满意了
今天搞了个flashplayer
哎累死了 代码都要改
也学到了不少东西 HOHO

期待仙剑三的电视剧
片尾不怎么满意 应该是还没看的原因吧 没融合感情
就写这么多吧= =

仙三剧图片故事

型号是dv2 1005ax AMD NEO 1.6GHZ,2G ram,250G,ATI HD3410.

4月4日在河南科技市场创新大厦的一个惠普店以5800的价格入手

送一个垃圾HP鼠标外加一个原装包 然后自己傻乎乎的用了110块贴了托盘 外壳 屏幕 键盘膜 哎 这贵的啊 其实完全没必要。。

因为4月16号就要回到国外上学 以前用的ACER的本子准备搁到家里 所以很急

现在已经降到5500-5600左右的价格了吧

最开始准备买联想Y330 但把科技市场问遍了就是没有货 然后在网上看到了这个本子 顿时觉得很惊艳 而且很轻

但配置确实不怎么样 尤其是CPU

开始JS忽悠我到6500 然后问了很多家都在6000以上 而且低于6000都不卖 看来刚上市的电脑最容易忽悠人

还好事先有准备 一句官网5999就把JS惹得不知道说啥了

然后就开始砍价

本来在百脑汇谈好了一个5600的 但谁知是样机 而且就那一台

所以放弃 当时比较晚了 而且转了一天累到不行 然后找了一家除了5600那个出价最低的 5850 JS信誓旦旦的说低于5850不卖

然后我就把电话挂了 不出一会儿又打来 说5800也行…然后实在太累了实在不想还价了就买了

好了 扯了那么多 还是扯到正题吧

首先是外观 相信很多本友已经看过了 今天也看到论坛里有另一位本友也发了不少图 比我照的好多了（手机200万像素的。。）

外观真的很漂亮 而且很薄 但是外壳和托盘上很容易沾上指纹 所以当时就贴膜了

其次是轻 因为本人在新加坡上大学 要天天背着笔记本跑来跑去 所以就想要一个重量轻点的

DV2女生都觉得轻了 本人更是觉得基本没什么重量 （有点夸张。。可能和原来的本台重有关系）

DV2新加坡的价格是1299新币 按照现在的汇率 大概5950人民币左右 在当地也不便宜

本来看中了X200 但由于实在没有money就放弃了 最便宜的要7100 砍价后也要6800

然后是CPU的问题了。。确实 单核的CPU满足不了负荷很大的工作 但对于一般的文字处理 上网 编程 中低级3D游戏都已满足 所以对于我来说 还是够用的

配备了ATI HD3410显卡 算是很入门的低级独立显卡 但是在轻薄本中配置独立显卡 在此价格下还是少数

玩AION在特效不高的情况下 还算是比较流畅的

像实况2009，WAR3等一些低3D的游戏都很流畅

1080P

720P

播1080P和720P都很流畅

但是在播1080P的时候CPU占用几乎全满 而且基本不能运行别的程序

说一下DV2的散热

新加坡天气比较热

在不开空调的情况下温度CPU温度一般在65度左右

但开空调的情况下一般在50-62度之间

在使用的时候 左托盘的温度比较高 右托盘没有什么感觉

但是机器底部中间是温度最高的地方 而且底部大部分都很高

出风口也很高 而且风扇基本一直都在转动 打算买个散热底座了…

屏幕是LG的 效果还不错

用EVEREST测试了一下内存和CPU

结果发现内存读取与写入的测试还算不错

但是CPU的测试确实很让人失望

VISTA下的CPU得分是3.4

硬盘测试

总体而言

对于DV2

我觉得还是够用的

但惠普的做工仍有待提高

总觉得托盘周围有些松动的感觉

屏幕框也比较松

散热确实不行 可能是DV系列的通病吧

另外此机器无光驱 但标配了一款HP可光雕刻录的USB外置光驱

电池是6芯的 正常使用有时候可以续航到将近3个小时 但大部分时候还是2个半小时左右
