I found Fuse 1 blown replaced it .

the Fuse is on the opposite side of the motherboard where the screen connector to motherboard is , it is covered in sticky protective plastic.

unfortunately to me the laptop stopped powering on something else has happened to it that I could not fined yet.

Power starts green light flashes then the fan starts then power off follows
