Hello - I have had this notebook brand new since 31 Mar 2018. UK based.
The notebook has worked perfectly until Monday 16 July 2018. Since then any time the notebook is switched on the normal HP logo and the spinning "wheel of dots" appears on the screen for 20 - 30 seconds. Once the logo disappears there is no further display showing but I can hear the fan and activity going on within the laptop itself so does not appear to be a power issue. I can tell the screen is not off as it has a hue to it (i.e. not black when it is powered off but a very dark blue almost midnight blue).
I have a standard keyboard and wireless mouse connected to the laptop as well as a seperate monitor. The seperate monitor does not detect any displays and simple powers off and says no video detected. The keyboard is working as I can switch the num lock/caps on/off and displays do light up on the keyboard.
I cannot see anything on the display of the laptop so cannot tell what (if anything) would be on the display if it were working.
I have unplugged all seperate devices and tried many re-boots but still nothing other than the HP logo for 20-30 seconds and screen going blank.
Have tried the hard reset as per the HP videos - nothing has changed.
Have used virtual assistant to see what it suggests and have tried a CMOS reset as laptop is post 2016. The CMOS ran for 20 mins or so and I could see the monitor was going from dark to less dark and back to dark but still not resolved.
I am at a loss and getting very frustrated as wasted 3-4 hours on this today when I really needed the laptop (typical when you want to use a laptop there's either a windows update or some other issue that means you just can't get on and use it!).
Any ideas/thoughts welcome :)
Thanks
David
