B50-80 wont turn won

[tanmoy_sil]

i switched off my lenovo b50-80 laptop and now it doesnt turns back on. The power button light glows whenever i click it but nothing comes up on the display or the keyboard light also doesnt glows.. I tried to click on the on the one key recovery but still nothing works.. Only the power button glows.. But whenever i plug the power brick after pressing the one key recovery key i get a short beep and also when i disconnect the power brick after pressing the one key recovery key.. What seems to be the problems? Please help.. I have exams and i need to study 🙁
Edit: i checked the fan.. It switches on when i press the power button and after a few seconds say 2 seconds it switches off again and also the hard disk lighr doesnt lights up

Hi, the first test you could perform, remove the battery, unplug the adapter, hold down the power button for one minute, connect the adapter and try booting.

I tried your way out but the laptop still doesnt boots.. The fan is doing the same thing.. And the hard disk light is still not glowing.

Try to reseat the RAM on the connector, if you have two, test one at a time.

The laptop is new.. I got it 5 days back.. I think they wont provide me warranty if i open the laptop.. During one key recovery option the laptop beep once everytime i connect or disconnet my power brick

Try to go in the BIOS.

There is no display.. The lcd is pitch black

You can try an external monitor if you have one, but I don't think it will make a change. If it's brand new, you could use the warranty for the repair of your laptop.
