My HP-Omen 17-CB0588NA will not turn on.
It does not acknowledge the power supply although this has been tested and is good.
Likewise the battery is serviceable and charged up.
I switched it on and off multiple times this morning (Diagnostics) and then it would not switch on.
I have tried the process of holding down the Power Key for 35 secs whilst everything is unplugged but this has not worked.
Is there a way for me to check if the motherboard has blown?
Thank you for any assistance
