Your keyboard has a special "Function key" (printed in blue). It is probably on the lower-left, next to the special Windows key or control key.
You also have several keys along the top row, also blue.
Hold the blue [Fn] and press the upper key that resembles a monitor. Release the two keys and wait a few seconds. If the monitor does not come on, wait a few more seconds, the press the two blue keys again. It will work.
By the way, the fluorescent lamp that creates the "backlight" for your laptop screen has burned out or the cable may be loose.

I would check the GPU by connecting an external monitor before booting it, that will allow the external drive to automatically work.

Toshiba m60-104 screen dark new screen new iverter


Have you tried an external monitor?

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the display shows on the external monitor that proves your video card is ok and your lcd screen is the issue. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If is shows on the external monitor, then you would have to question if the new screen and lcd inverter is bad. Just because they are new don't mean they work. Are you sure you purchased the lcd screen and inverter that is for your model?

Compaq presario c500 has power and charges but the screen stays off disks will eject and you can hear the computer running just nothing on the screen.


hi there,
Please have it plugged it onto an external monitor to make sure that the problem is not with the LCD. Is there a backlight on the LCD or is it totally dark?
If the external monitor gives out an image it means that the LCD might be busted but do you know the keyboard shortcut to switch between the external monitor and the laptop screen?
You can try FN+ F5. if that does not work you definitely have to try it out on a external monitor.

Monitor too dark....


Usually every laptop has the option of adjusting the screen brightness as you would want the screen to be pretty dim when running on battery to conserve battery life.
First thing to check would be just that.
