Why does my laptop keep turning off and on?

Hi, this morning I tried using my laptop but for some reason it would go pass the logo screen and then it goes to the Novo button menu screen but when I try to click on an option it turns off then back on and off repeatedly, I tried holding down the power button but it shuts off and on before I can do that, what do you think the problem might be? Thank you

I've had a couple of these come into my shop with board issues. They are always miserable hard to diagnose problems and I've yet to fix one yet. This sounds like how they start to fail. Then it will not power on and the keyboard light will flash every 5 seconds. I have no idea what is causing this on them. May be a RTC issue (The thing that puts all the "thinking" components on a timer so they can all talk to each other efficiently) . But as of right now the only solution i've found is a new motherboard.

If your laptop is showing no signs of life and refuses to turn on, use this Lenovo IdeaPad U530 Touch Does Not Turn On problem page for possible causes and solutions.
