When i first bought the laptop 2-3months ago, i noticed the lightbulb indicator (power indicator) was blinking everytime i set the laptop to sleep. But few days ago my laptop had some issues with the fingerprint sensor caused by windows update which i had to bring the laptop to repair to clean reinstall windows 10 again. After installing windows 10 i noticed the power indicator stopped blinking when i set it to sleep mode. Anybody knows the reason? should it be blinking or not blinking?
If it is sleeping fine, and no other problems, I don't think the blinking will really matter. However, should it worry you that much, you can always take it back to the repair people and say 'why is it doing this after you worked on it'.
