Écran noir à l'allumage, touche "capsLock" qui clignote

[Marieb1]

Bonjour,
Lorsque j'allume mon ordinateur l'écran reste noir. Pourtant il s'allume normalement, bruit de ventilation au démarrage et led qui s'allume. Seul problème, l'écran reste noir et la touche de clavier caps lock clignote. Avez vous une idée s'il vous plaît ?

> the CAPS LOCK lamp flashes.

Does it flash in a repeating pattern, e.g.,  on, off, on, off, on, off, on, off, pause, on, off, on, off, long pause?
