Have you updated a Graphic driver? Does it Dim on battery and AC? Look at power settings. Control Panel, Power. You could Rool-Back the graphic driver to see if that changes the problem. A Gateway mt6841 has Windows XP OS, right?
Disconnect the power cable from the Notebook and then remove the Battery pack. While the Battery pack is removed, press and hold the power button on the Notebook for 15 seconds.
Next, reinsert the Battery pack and connect the power cord to the Notebook and turn it ON. While the Computer is booting, you can view the information on the bottom of the screen to get to the Setup Screen.
On the Setup screen, use the right arrow key to highlight the "Exit" menu, then select the option "load/get default" and press the Enter key followed by F10 keypress to reset the BIOS and save and exit the screen.
Check your power settings, where the little battery is in your righthand lower tray,look for change screen brightness or something like that,there should be 2 columns, make sure u pick the one that says"plugged in" instead of the while running on battery setting.Adjust accordingly.
this is normal if you have battery save mode. right click on the desktop and check your settings for screen or go into the control panel and check your battery save modes. not real sure where it is but that should give you a start of where to look.
Any beeps when you turn it on? unplug everything and then plug it back
in. Make sure the monitor connections are good and that you have it
turned on. Again make sure it's turned on. Sometimes it's the simple
stuff. Was the monitor working well before it failed? Do you have a
video card? Remove the battery, AC, count to ten and try one last time?
