原因是bios里的键盘没有激活,按照以下办法(英文的,应该能看懂)
Turn on the computer and press the "Delete" key several times as soon as you see the initial boot or company logo screen. Wait for the main BIOS setup screen to appear.
4
Press the right or left arrow keys to move the cursor to the "Advanced" or "Advanced Settings" menu option. Press the "Enter" key.
5
Move the cursor to the "Integrated Peripherals" or "Peripheral Configuration" menu option. Press the "Enter" key.
6
Press the down-arrow key to navigate to the "USB Controllers" option. Press the "+" or "-" key to change the menu option to "Enabled."
7
Move the cursor to the "USB Legacy Support" or "USB Legacy Function" field. Press the "+" key repeatedly until the value option changes to "Enabled."
8
Press the "F10" key to save changes to the BIOS settings and exit the setup utility. Wait until the computer begins to restart and then press the power button and hold it for approximately four or five seconds. The computer shuts down completely.

开机按F8 进入安全模式看能不能使用键盘,如果能进入系统后用360 把一些无关启动项关了.如果不能重装系统
1.我想问下你要输入密码时,输入框里有没有光标闪动,如果没有,就按tab键把光标移到输入框才能输入.
2.输入密码是使用小数字键盘的???如果是,小数字键盘灯有没有亮啊,没有就要按下numlock键,灯亮了,才能输入.
一般情况应该是这两个问题之一,如果是笔记本的电脑,试下键盘左边的大键盘的数字键.
换个键盘试试,实在不行重做下系统
既然是品牌机,打客服电话嘛
这个型号不熟悉,不过联想是经常会做硬件限制的,不让用户改硬件
还有WinPE为什么不能启动,不能光盘启动吗
