Hi,

Please do try these troubleshooting steps that may help in solving the issue.
- Start by doing a hard reboot, remove the battery and unplug its AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If these doesn't work, remove the CMOS battery inside the laptop then put it back in and that should reset BIOS.

Here's a video tutorial on how to disassemble your laptop that may help.

If it doesn't work after resetting BIOS do try these other troubleshooting steps.
- Try to connect an external monitor and see if it will display on it.
- If it does display on the external monitor press the Windows key + P at the same time and select Display Only.
- If it doesn't work do reseat the RAM's, remove them all for couple of seconds then put them back in making sure that everything is seated properly in each slot.

If all these will not work you may need to contact Lenovo for a repair if it's still under the factory warranty.
