If the Hub was faulty, then it is possible that there are still faulty components on the motherboard, you need to check all incoming voltages (19volt / 5volt / 3volt) also check the status of the BIOS chip, it may be faulty or has a broken BIOS.

They said after the hub  replace,  theres no shortage on the board , but i mentioned him that  theres maybe a blow fuse somewherein the power board,  we can  simply  connect  to the bios chip  with a cabled eeprom writer and flash it? Or need to be  replaced,  or desolder from the board and write it?
