I had the sample problem with my inspiron. Check you bios settings. Make sure you've selected simul mode instead of LCD mode. Now this may cause your failsafe terminals (F1-F6) to flicker on the laptop itself. For some strange reason, when you have an external monitor plugged in, BIOS treats that as the primary monitor, and you secondary monitor (internal LCD) will flicker on the terminals. Good luck Graham
