Backlight on CD Boot

Hi there, first post here. I’ve been using Haiku on a desktop PC with absolutely no problems. I’ve been wanting to install it on my laptop computer too (HP DV1000 Special Edition) but when I insert the CD to boot Haiku, the screen on my laptop starts to glow brighter and brighter, almost like the backlight is going to just burn right out of the screen. Is there any kind of fix for this? Many thanks.
