联想lancer5B2(AMD k16IMC)能支持的内存条
扩充内存，买和原厂内存同样接口的就可以，品牌和频率都可以不一样，一般购买大厂产品就没什么问题。
要判断电脑使用的内存参数，建议使用CPU-Z来检测，运行后在内存标签和SPD标签，会显示当前系统内存的参数。
如果确实想买一样品牌的内存，又看不懂内存参数的，可以把CPU-Z的信息拍图发上来，方便确定问题。
这是什么主板
您可以这样做（如果您主板还可以用）：
根据你的BIOS ID查询你的主板品牌和型号
资料来源自各大BIOS修改网
如果想刷新IOS而不知道你的主板是什么品牌什么型号的，可以使用以下方法查询，利用BIOS－ID获得主板的信息。
以下是AWARD的BIOS－ID，在计算机启动，进行设备自检时，按下PAUSE键暂停，这时屏幕左下端的一段字符串就是我们
所说的BIOS－ID。
AWARD的BIOS－ID一般分为以下几个部分：（以技嘉BX主板为例）
07／06／2000－i440BX－8671－2A69KG0EC－ 00（自己编的，不知道对不对）
BIOS生产日期芯片组 I／O控制器芯片组编码（前五位）厂商编码（第六七位）
i440BX＝芯片组
8671＝I／O控制器
2A69KG0EC=> 2A69K＝2A69K: Intel 440BX chipset(Pentium II based chipset)芯片组编码（前五位）
2A69KG0EC=> G0=技嘉Giga-byte厂商编码（第六七位）

联想昭和E40-70拆机图解。
昭和没有E40-70吧，是不是联想昭阳E40-70。下面介绍下昭阳E40-70的拆机过程。
拆掉电池，然后拆卸底壳两个螺丝
拆键盘螺丝，抽出光驱
拆去这连个螺丝
取下这5颗底盖螺丝
取下硬盘和内存
取下光驱的这两个螺丝
从键盘上部撬起键盘
拿掉键盘排线
拔出这4个数据线
从底部两边撬起
取下屏幕排线。取下USB排线
取下WIFI的螺丝和线。取下图中的插头
取下固定主板的螺丝和风扇的一个螺丝
取下风扇的另一个螺丝和风扇电源线
然后就该清灰清灰了。这款电脑的CPU大概是焊接上去的，还是别升级这块了。本来是电脑不小心洒上水了，用电吹风把键盘吹成这样了，所以此次拆机原本是换个键盘，也顺便拆开把里边吹吹干，再顺便清个灰。
