Lenovo Yoga 10 tablet vibrates and screen flashes whilst charging?

So I just went to put on my tablet and it didn't turn on. I thought that it may have been out of battery, so I put it on charge.
All of a sudden, it begins to vibrate every 3-4 seconds and this is accompanied with the screen flashing a white light, synchronised with each vibration. The power button light also lights up with each vibration.

I have tried to hold the power button down for a long time but it hasn't worked. I'm wondering as to whether I should just leave it and try to turn it on in the morning?

Any help would be greatly appreciated. I'm in desperate need for my tablet since I'm doing exam and it is home to all my secondary revision material.
