problème de démarrage ordinateur lenovo G50

[BEDECARRAX]

Bonjour,

En marche, l'ordinateur avec ubuntu 18.04 fonctionne très bien. Il s'éteint facilement. Pour le re démarrer, l'écran reste noir très longtemps, parfois pendant une heure avant de retrouver le bureau et re fonctionner normalement. Le disque dur fonctionne normalement, la barette mémoire aussi que j'ai testé en la remplaçant par une neuve: le problème reste. Je ne comprends pas la cause de ce problème.
Pouvez vous m'aider? Merci

Hello,

When running, the computer with ubuntu 18.04 works very well. It goes out easily. To restart it, the screen remains black for a very long time, sometimes for an hour before finding the office and re-operating normally. The hard drive works normally, the memory module also that I tested by replacing it with a new one: the problem remains. I do not understand the cause of this problem.
Can you help me? Thank you
(I do not understand English)
