Lenovo Legion Y520 not booting

took the backcover off my laptop to clean it from dust and then i tried to turn it on, but the keyboard is just blinking. I cant even get into the boot menu. Sorry for the bad English.

Keyboard blinking? - - can you be more specific about which LED is blinking?

The power led and the whole keyboard is are blinking every two seconds.

Well I just read a post from someone who had the same symptoms on their Lenovo and when he contacted their tech support they told him that the main board (motherboard) was faulty and he had to send it back to the manufacturer to have it replaced.

That's all I can tell you.
