Whenever I open my laptop it's screen stays black, LEDs are ok and the coolers too. After I press a few times on the keyboard it starts beeping loudly. What can I do?

PS: Every question from you will be answered, thank you :D
 
Hi,

Please do try these troubleshooting steps that hopefully would help. I suggested this troubleshooting steps to others who had the same concern.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try loading it again in BIOS.
- If these will not work proceed with reseating the RAM's, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If these steps will still not work, connect an external monitor and see if you'll get a display on it. If there's a display on the external monitor that means the problem lies in the built in LCD or the ribbon cable that connects the display to the motherboard.
- Try to open the laptop and check the ribbon cable if it's connected properly. You can take both ends out then put it back in just to make sure it's seated properly.
- But if there's also no display on the external monitor the problem lies in the motherboard.
