I have Dell Latitude D630 which is 4 years and 4 months old. Most of the time it is docked with screen closed running two external monitors. However, if I use the laptop's screen, it is dark (readable but darker than should be) for the first 10 minutes after boot. Then, it lights up gradually. I presume that it is a problem with a backlight. Should I just buy a backlight lamp like this and how many?
