There could be a number of things wrong with this laptop.

Firstly try to plug in an external monitor using a VGA cable
- If this works and you get a display on the screen then this eliminates the graphics chips and points to a faulty screen. This can be easily replaced and the panels are fairly cheap.

If you do not get a display on the monitor then it could be a fault with the graphics chip.
- This isn't an easy fix and will require the removal of the mother board to either reheat the chip using a heatgun or reballing the bga back to the board. Probably worth sending to a professional unless you wish to try it yourself - we can guide you.

On some laptops (hp mainly) I have noticed that if the ram if faulty then you will get no display on with the internal or external display. But the fault can be identified by the flashing caps lock and scroll lock keys.

When you turn the laptop on do you see any of the lights on the keys flash? (assuming there are lights on your caps and scroll lock keys)

Or do you hear any beeps on startup? if so then tell us how they sound, usually described as long and short beeps.

So for example if you hear 4 beeps we need to know how they sound eg long beep, long beep, short beep, short beep.

We can use this to identify the error.

This has been known to 'fix' a wide variety of problems, is quick and easy to do, and cannot hurt:
Unplug the laptop. Remove the battery. Press the power button and release it slowly 5 or 6 times.
Reinstall the battery and try the laptop again.

If this does not work, try above (reply #1) and tell us any and all things you observe including any sounds, lights, and even brief flashes to the display. Do you hear the fan? DO you hear the hard drive spinning (not possible if SSD drive so mention this if applicable)? When starting, do you hear processor sounds (low groaning sounds that vary in pitch)? Do any little lights (LED's) come on or flash either continuously or during start up (including by network jack)? Have you experienced any related or apparently unrelated problems with the system at all recently (display or otherwise)? These answers will help guide the search for an answer to your problem. We are not there so you have to be our eyes and ears and may have to try many suggestions and tests.

You have to be a little bit crazy to keep you from going insane.

If you never ever see anything on the screen it is almost certainly a hardware issue. As per #1 try an external monitor on it and let us know what happens - this will narrow things down a bit.

Please answer the questions as that will help us to help you.

Always pop back and let us know the outcome - thanks

Glad you found the fault at least we/you know its the graphics chip, just to point out, the hari dryer solution is temporary, as the chip heats up it will probably start to cause problems again,

Did you remove the motherboard, or at least expose the chip or did you blow the hair dryer over the keyboard (as some people do)?

In either case it would be good to fully remove the motherboard and use a heatgun to heat the chip back to the board, again this isn't the preferred method but reballing can be costly.

Good luck and thanks for coming back with your findings.
