While working on a large deployment project I noticed a strange behaviour with HP laptops. After deploying some laptops didn’t pass the HP logo. Nothing happend.
After searching the internet and contacting HP (no solution) the solution came through (by mistake :-))
When you see the above hp logo and your laptop doesn’t start through…. press the up (no keypad) or the 8 (with the up arrow) and voila!
After pressing the up arrow the problem is solved. 🙂
