Gateway 450ROG, will not start. Red DVD/CD ROM

I have the very same problem, the Drive light turns red, the screen is "black" and the battery charging light indicator on the front is off. No differance if I'm traying to power up on battery or AC-adapter.

Before this problem appeared I had problems where the laptop was powering off, with no warning, and I had to restart it. This happened several times and was going on for about a week before it died totally. Can it be the CMOS battery on the mother board? Anyone having clue what the problem could be?

Screen is black

The cable is dislodged or you have a failing lcd.If you want to repair this yourself.Check online for a replacement cable and a Lcd too.Then you will have to open the Lcd Bazel to remove or check the cable.Make sure when you attempt this there is no power attached ,battery and Ac Adapter.
Good luck

Laptop screen very dark

the screen is not a sealed unit... and the backlight and the lcd bulb can both be changed out...
I do it on a daily basis....

It is way cheaper to change out the lcd bulb than it is to replace the lcd display panel... Way CHEAPER

the results are the same

Bios Battery

What I did was removed all the case screws.and gently pulled the front left corner up.(front left as if you were looking at the screen).
You will need some hook nosed pliers to reach in and pull it out. replace with same size battery.

CMOS BATTERY

Gateway 450ROG CMOS BatterySmall internal battery that maintains calendar and clock settings.

PLEASE NOTE: This is not the battery that powers your laptop; it only maintains certain internal settings. If you need a main battery, please refer to the page on our web site for your laptop model.

CMOS batteries are located on the motherboard; if you are not comfortable with the inner workings of your laptop, you may want to consider having the battery installed by a qualified technician.

Here is the link to their site for your cmos battery

Gateway 450rog does not power on

Sounds like a voltage regulator. Have the system diagnosed at a repair shop. Sorry I know this isn't what you wanted to hear, but is probably the correct answer.
