HP Recommended
Product: HP ZBook 15 G6 Mobile Workstation
Operating System: Microsoft Windows 10 (64-bit)

My laptop HP zBook 15 G6 was not used for couple of months. It was on desk unused, until I tried using it couple of days back. It didn't switched on at the first try. So, I put it on power & tried turning it ON. The laptop starts with Power key light ON + Keyboard lights turning ON, Both Fans running at full speed ... but the screen is completely black. The Caps & Num Lock blinks slowly for about 5 times & then stops.

 

Can anyone suggest what went wrong & something that I should try before reaching out to HP support.
