Thanks for your response, i have already try to disconnect the internal keyboard and use an external apple usb keyboard but with no luck (caps-lock doesn’t lit) and still no response to cmd ⌘ + Option + P + R or Option (⌥) to select the boot device !

Hello to all, this time i meet a symptom that drive me mad !

I have a macbook air 11" A1370 - Board id 820-3024-B (Core i5 1.6 11 (Mid-2011) that is stuck in a boot system loop (chime loop) this computer start and i hear the chime sound that repeat endlessly with only a white screen.

Sometime (rarely) it chime normally (one time) and i can see the blinking folder (this computer doesn't have a ssd for now) after a certain delay.

I realized that if i unplug the lvds cable i does not have any more chime loop… i test on an external screen with adapter...
