I have not yet been able to diagnose the cause (drivers seem up to date and nothing obvious in the EventLogs) but I found a work around. If your laptop (mines a HP 4540) will display the boot screen but turns purple after login (as mines does), closng the lid and letting the machine go into 'Sleep' and then opening it up seems to work.
i got a new laptop yesterday it was the floor model. when i turn it on the screen is black and where the tab's go is purple (in chrome). I opened word documents and the page that should be white was black and the top was purple, all the writing was white with some in neon green, when i run the mouse over anything it is highlighted neon blue. everything appears to work but i cannot produce accurate work under these conditions.
thank you for your help.
Here's full article on the problem and its solution.

This is most likely a faulty laptop screen. A good computer shop should be able to replace broken parts to fix this.
my laptop is turned on but my screen won't work.
If you see pictures, then your computer screen is turned on.
If your computer's splash screen can be modified (turned off or on) this setting is going to be found in the BIOS. You will have to consult information for your specific manufactuer to see if the splash screen can be turned off or on. Most can be, a few cannot.

That's the bluescreen of death.... Call computer company.
Check that the cable for your monitor is correctly inserted into the computer and into the monitor, and is turned on.
get a new laptop
Its the fan and and all the parts in the computer that starting up.
If your laptop is turned on and it looks like it's plugged in, the batter could possibly be dead or the connection from the outlet to the computer has a problem.
I am not sure exactly what you mean by this question, but I thing you mean, "When you put your laptop into sleep mode does it shut down?" the answer to the question I just stated would be: When you put your laptop into sleep mode, it does not shut down, it just turns the screen blank to save battery power. To exit out of sleep mode you can either move around your mouse, or press any button on your keyboard. Once you do this, all the windows that you had up when you turned your computer to sleep, should still be on your screen. Hope this helped!
