Well, sounds like a couple of things if an external monitor works. First, toggle a couple of times between lcd and external just to make sure that it's not set to external only.
If that's no help, look closely at the lcd while the operating system is running. Can you see any image at all? If so (or if not) you have a bad inverter (we have them at the shop for around 25.00). The other possibilities are a bad backlight (which means a new lcd, about 75.00) or it's possible the lcd cable has simply came loose from it's socket.
That's about all it could be on these models if you're getting an external image. I'm using a T30 right now. They tend to have bad memory slots, but great machines.

if the display on the external monitor is fine in that case it is an issue with the LCD as you get a video output on external monitor
you have to get the LCD either repaired or replaced.

This must surely be a problem with your monitor, because you say that you see the white screen while boot up. If this is a graphic driver issue, you may have the problem after booting up in windows. Since its been only a month old laptop, the product must be in warranty for sure. Take away any CDs in the drive, any USB drives and see if this white screen appears. Let us know.

i have solve the problem for my hp nx7300. mine used to show everything that should be shown on the screen but had the screen placed in a Conner so small. i solved this by uninstalling the monitor and unknown device drivers. i have then installed the unknown device as a blue-tooth adapter to avoid this problem recurring. hope this sorts out some people's problem. the other half screen with half completely not shown has to do with the cable connecting the monitor and the CPU. remember solving this for my friend by cleaning the connection port.

Tips for a great answer:
Shine a flashlight on the dark screen to see if you barely
see the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.
