Product: ProBook 6550b

Hi All,

 

Suddenly my HP notebook won't boot.

 

When I press the "on" button the laptop starts (Led lights, fan) but a black screen. When I press Num Lock or Caps Lock the led doesn't go on. So It looks like it won't boot. No beeps at startup. No Disk with weird noises.

  • Tried to enter BIOS and Uefi
  • Tried to do a hard reset
  • Tried to remove, an attach RAM
  • Tried to attach a second monitor
  • Tried Windows + CTRL + Shift + B

Any suggestions? 

Is it a thing to try and replace the CMOS on BIOS? It is kind of hard job for a not IT person.

 

Thanks !
