I connected my laptop to an hdmi tv, from there its screen froze, i turned it off removed it from the hdmi cable, tried to switch it on but it failed to boot up. What am getting is a dark screen no evidence of boot up at the same time after switching it on the led stays on for a few seconds then laptop switches its self off.

Checking the HMM https://download.lenovo.com/consumer/mob...
I notice there is a Novo button. This could be a small pinhole or button near the audio connector.
Try pressing that, see if it boots

and just see if that will kickstart it back to life,
otherwise I would try a power refresh (open back, disconnect battery, hold power button in for >30seconds, connect AC and see if it will turn on.
If not, a full refresh where you also unplug the RTC battery for 5mins, reconnect, plug AC and see if it turns on.
That would reset BIOS to defaults, so will have to set the clock again and make any customizations in BIOS again.
Not sure if this will help, but I'd give it a try.
If not, then something else must be going on - perhaps hardware related?

Is their any indication that the device is charging when plugged in?
