Compaq Presario C700 Notebook Backlight only works on Battery Mode

I recently bought the Presario C700 and ive discovered that the backlight for the screen only works when the notebook is on battery mode. When i plug it into the mains supply the backlight goes out and the screen dims. You can still see things ok but with the backlight things look alot better.

I have looked arround but theirs little options for this kind of thing as i think the version of windows i have isnt that laptop friendly.

Im running xp pro sp3 on it. I can get some info up like battery power and different standby timers and such based on battery or wired but theirs nothing about the backlight.

Any help would be apprechiated,

Thanks

Mike

First of all, let me inform you that there will be different brightness settings when the Notebook is running with Battery and Power Adapter.
I recommend you to try increasing the Brightness when the Power Adapter is connected to the Notebook by following the steps below :
Connect the Power Adapter to the Notebook and turn on the Notebook.
Now, hold the FN Key which can be found at the left bottom of the keyboard next to the Ctrl key and press the F8 button to increase the Brightness.
This should increase the Brightness of the LCD. Increase the Brightness to your comfirtable level and you are done.
Now, if you disconnect the Power Adapter, the display will appear either darker or brighter as per the previous settings with the Battery.
This is to save battery power like if the Brightness settings are same for both the situations like when the Notebook is connected with the Battery and the power adapter, battery will drain up fast.
So, if you can have different brightness settings for when the Notebook is running with Battery and Power Adapter, it is possible to maintain battery with low brightness.
Hope this helps.....

Screen goes black after login


boot in safe mode or vga mode by holding f8 on startup. If you can see vga or safe mode the resoution is too high for the card or monitor. Once in via reduced mode uninstall your video driver and reboot. If it tries to add a driver make sure to set the resolution lower. If low resolution doesn't work then you may have a hardware problem.

Either bad connection/ribbon cable or screen has tanked. Could also be a display driver but very minimal chance.
