This may be caused by the video graphics cards. If you have a warranty, check with HP and they will fix for free as they warranty all hardware for two years.

You can check to make sure it is the video graphics or the screen by running a simple test. Get a monitor and attach the laptop to the monitor. If you see a picture, then the screen (probably backlight) is out. If you do not see anything, then it is definetly your video graphics card. You can order a new screen or VGA card on eBay, which I highly recommend to save money. Get a friend or you can put it in, just make sure you put the laptop back together perfectly and protect from static electricity.

It is easier to get another replacement screen if the backlight is out because these can be hard to replace. The backlight usually cost a couple of dollars but the frustration of trying to replace is like trying to replace a lightbulb in a very tight spot. A screen will run you around 40 dollars. If it's the VGA, then you are looking at 60-90 dollars.

Try to hook the computer to an external monitor using a vga cord or super video, whichever you have. Set the tv to that input and see if the laptop switches over to it. If you see the computer image on the tv, then you very well may have a damagesd and dead screen. Those can be purchased online on ebay for around 100-150 bucks. I can give you a service manual and an LCD replacement manual if that is the case. If you don't get a picture on either one then you have probably lost the video card or video processor.

It may be trying to display on an external monitor - try hitting Fn+F7 - if that doesn't work, contact hp support ASAP, as the laptop should still be under warranty, and there may be an issue w/ the lcd or connection to the motherboard.

Check to see if you have a key which switches display from the laptop to an external monitor. This may be a Fn (Function) key (sometimes coloured blue). If so, hold down the Fn key and press this key. It usually has a smal icon of a monitor on it. It may well be shared as a normal key.

That sounds like a problem with your GPU, this is very common with Nvidia graphics cards when built onto motherboards for mobile devices. First contact HP to see if you have any warranty with them, if not then you can either look for a company that specialises in board repair in your area or if you are brave try a DIY fix. Search 'motherboard DIY reflow' on google or youtube to see an example. Hope this helps,

Try the keyboard on another laptop or desktop computer, if it works on another computer then that means there is an issue with your laptop USB ports.

If it doesn't work on any other computer then that means the keyboard is bad and would need to be replaced.
