联想系列笔记本清除BIOS密码大全

笔记本电脑打扫密码的方法一般有四种，分辨是：通用密码、跳线开关、BIOS电池放电、笔记本厂家供给的特别方法
一、通用密码
通用密码不是每个笔记本厂家的机器都有，目前有通用密码的机型有。
ASE：
昭阳7100、7110、7000：通用密码为 maximum
昭阳7200、7500、7550、6600：通用密码为 6475457
CLEVO：
昭阳6100、6200、6220、6230：通用密码为 659835
COMPAL：
30B3和30W的通用密码雷同：blvjch
实用机型：昭阳 1200、1210、1250 、8350、8360、8365等。
二、跳线开关
FIC ：
5600、5650、5660、5750打扫密码跳线开关是SW3-4，即SW3的第四个开关。
具体方法是将电源及电池去掉，将内存盖板卸掉后即可看到SW3（靠近BIOS），将第四个开关拨到ON地位，再拨回原位即可（有的机型会重新启动）。
实用机型：昭阳6700、6800、7600、6895、7695系列。
A450打扫密码跳线开关是SW6-6，位于内存盖板下。方法与5600系列雷同。
实用机型：昭阳2100、6900、8010系列。
三、BIOS放电
上面介绍的机型打扫密码方法比较简略易行，剩下的其它机型就只能靠拆开机器拔掉BIOS电池放电来打扫密码了，由于涉及拆机器，所以此方法是最麻烦的方法也是打扫密码最基础的方法。
四、笔记本厂家供给的特别方法
FIC 6000系列机器：利用特别的并口短路环和清密码专用软盘。并口短路环的制作遵守以下原则：
PIN 2 to PIN 15
PIN 3 to PIN 13
PIN 4 to PIN 11
PIN 5 to PIN 12
PIN 6 to PIN 10
具体方法是将短路环接入并口，将清密码专用软盘插入软驱中，开机，看到软驱教唆灯一闪即灭，此时密码已经清掉，断电重新开机即可。
实用机型：昭阳5200、6500、7250、6588、6500E。
SANYO机器设计奇特，拔掉BIOS电池也无法打扫掉密码，只能利用厂家供给的方法才干清掉：
USX3P：
昭阳8100、8200：厂家供给了一个专门打扫密码的程序“password.exe”。
具体方法：1、将两台机器用串口线连接起来（另一台机器不限机型）。
2、启动另一台机器（不限机型）后履行password.exe，程序履行后屏幕会提示恳求8100或8200开机。
3、将8100或8200内存盖板取下，找到电阻R87，用镊子将其短路，然后开机，另一台机器屏幕将会显示正在更新BIOS以及进度值，直到提示结束。
如果不行，多试几回。
SANYO FX-8/FX-8V：昭阳9000系列
FX-8和FX-8V的差别是PCMCIA和显示把持芯片不同，因此BIOS信息也不同。厂家为此供给了两个打扫密码程序：PASSCL8（实用FX-8）、PASSCL8V（实用FX-8V）。这两种机器外观一样，如何差别呢？将内存盖板卸下，在内存插槽上有一行数字，第一位为“4”表现FX-8；第一位为“2”表现FX-8V。具体操作步骤为：
1、 制作清密码软盘（用PASSCL8制作打扫FX-8主板密码软盘，用PASSCL8V制作打扫FX-8V主板密码软盘）
命令格式：PASSCL8 /CRISIS 或PASSCL8V /CRISIS 按照提示制作完成软盘。
2、 保持关机状态（保证电池有电或接入AC适配器），软驱中插入作好的相应机型的软盘。
3、 将所有扩充内存拔掉
4、 如果主板是FX-8型 ：用细针捅主机底部光驱附近的小洞，机器将主动启动并运行软盘中程序打扫掉密码。
如果主板是FX-8V型 ：卸掉内存盖板，短路内存附近电阻R991，机器将主动启动并运行软盘中的程序打扫掉密码。
如果不行，多试几回。
昭阳S300系列笔记本电脑打扫硬盘密码程序的利用阐明：
1．需要有2台联想昭阳S300机器，一台正常，一台需要解除密码。
2.先启动要解除密码的机器，按F2进入BIOS设置，找出硬盘序列号，并记下前8位。
3.启动正常的机器，运行MASHDD2.EXE，会得到一个密码（注意大小写）。
4.再次启动有问题的机器，在提示输入密码的时候，输错3次，然后输入正确的密码（注意大小写）。
5.完成。
注意：该软件只能运用在联想昭阳S300机型上！
昭阳v6打扫密码方法：
打开内存盖板，在内存边有两个J1小块，短接5秒中以上。
昭阳8500系列
拔掉CMOS电池，长时间短接COMS电池引角，即可放电。
昭阳X500（Cq12）
Pls open the DRAM door and short J1(location in the attach file) about 3 second at least to clear password.
昭阳70/81系列打扫方法：
打开内存后盖，会看到6个DIP开关；将第四个DIP开关从OFF拨到ON，开机加电，再关机，将DIP从ON拨到OFF即可。
昭阳15
打扫方法：拨掉CMOS电池放电；
CMOS电池地位：在触控板左下角；

1. 打扫BIOS密码须通过主板上的4针跳线中的PIN1：（拆开键盘，位于键盘下）默认为OFF，拨到ON，进入BIOS进行设置，打扫密码后，将跳线拨回OFF即可。
2. 指纹锁的强行打扫，须拆下键盘，将指纹辨认器与主板的连接线拔下；开机进入BIOS，将指纹辨认功效DISAbled，之后再将连线接回。
