I recently purchased an Asus UL30Vt-X1, which according to the specs has an LED backlight for the screen. It definitely appears to be an LED backlight, but the laptop still has a sticker that the lamp in the display contains mercury.
Why is this warning sticker there if it has an LED backlight?
Edit: The exact wording from the sticker:
The lamp in this display contains mercury. Recycle or dispose according to local, state and federal law.
