A friend recently was given an older Compaq Presario 2500 laptop that was used for a short time in a business that went under. The laptop is literally almost new but once (apparently) had an external monitor attached.
Hence the issue.
i think.
The machines screen sometimes goes so dim you can hardly see it.
Its been that way for some time. My first thought was that the backlight had gone out and we had started the process of getting it repaired.
In the mean time i I had been accessing the machine remotely to update it, during that process i came across the settings for the graphics card.
there i noticed that the display listed as active is : Digital Flat Panel (1024x768) on Radeon IGP 345M
the drop down shows (Default Monitor) on on Radeon IGP 345M If i choose this as the active monitor then i and only allowed 640x480 at 8 bit color depth, but if i hit apply it reverts back to the digital flat panel

Device manager/monitors list:
Default Monitor
Default Monitor
Digital Flat Panel (1024x768)

So, perhaps the dimming of the laptops monitor is related to this somehow? Like maybe it is expecting and external monitor so the laptops monitor is dimmed?
What happens/ can it just uninstall the three listed monitors ?

Any thoughts?

That sounds normal to me, I don't see any reason that it would relate to either use of an external monitor or the display becoming extremely dim. If it was me, I'd continue to investigate a backlight problem.
