I was having the same problem in lenovo s10 3s , but I took it to service station and found that the internal cable which connects the screen to base was loose. You too take it to service station because no power issues and os problem is to do with screen flikr.
I have the same issue....I reboot and get stuck. I also then hear an echo, but no keyboard button does anything. Help! I have Lenovo g700 and windows 8.1
Step 1: There are a variety of reasons you may need to reboot a Lenovo laptop. These can include the installation of a new program, the dreaded blue screen of death or to free up memory that has been hijacked by a program that is now closed. There are three ways to reboot and all are simple to accomplish.
Click on your start menu button on your screen. Click on "Shut Down" or "Turn Off Computer." Click on the drop down box if you are running a version of Windows before XP (such as 2000 or 98). Select the "Restart" option and then click "OK." On XP or later versions, click on "Restart." The laptop will then reboot. Press and hold down the "Alt," "Ctrl" and "Shift" keys simultaneously. This will bring up the Task Manager. Pressing and holding the same keys again will force the computer to shut down. Press the power button to reboot the computer. This feature should be used when the mouse has stopped working and you cannot access the start button. Hold the power button in the "Off" position for approximately 5 seconds. This will force the machine to shut down. Press or slide the button again to reboot the laptop. Use this process when you get the "blue screen of death" or the computer is not responding to either the mouse or the keyboard.
