Week old laptop with Windows 8.1 giving blank screen at Startup

Question

I have a HP Laptop. I don't know the exact model number but it has the following configuration :- Intel Core-i5 4210u
1.7Ghz Processor, Nvidia 820M GPU and 4GB RAM. It came preinstalled with Windows 8.1
Now this is my problem :-
Whenever I power-up the laptop by using the power-button, I get the Windows 8 logo and than instead of the login-screen it
gives me a black screen. Its not even a black screen, the display is exactly as it is when the laptop turned off(nothing
at all on the screen). But I know that the laptop is running because the power button and caps-lock key is illuminated.
Now I discovered that in order to get to the Login Screen, I have to manually close the lid and open it. This however does
not work everytime. How can I fix it.
Please someone help me. It is a new laptop and I can't return it because I bought t from a different country

Hello svmpua,
Welcome to the HP Forums!
I understand you are having issues with a blank display on your new notebook. It would help to know which product you are using. For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number?
In the meantime I would suggest going through this document for your issue: Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot.
You may also want to confirm if this is a hardware or software issue. Does the BIOS screen load properly? You can access this by repeatedly tapping F10 while the computer turns on. If this does not load properly try an external monitor to determine if it is a hardware problem. If it does load OK, you may want to try safe mode and see if the display works properly there. 
Furthermore, it could be the physical connections on the display cable. Opening and closing the lid may be wiggling the cable enough to reseat the connection temporarily. You can see how to reseat that connection in the Service and Maintenance Guide. This will not void your warranty as long as you follow the directs. You can find the guide in the User Guides section of the support page for your product, which will require the exact product or model number.
You may also want to read this document about HP's Global Warranty: Global Warranty and FAQs. In short this shows you still have protection even if the unit is purchased in another country, but the coverage depends on part availability in the country you are currently located in. You can always try calling HP Phone Support, they may be able to provide service for you. You can contact HP Technical Support at 1-800-474-6836 in North America. For all other regions click here.
I look forward to your reply!
