Hello everybody. I've got Lenovo Flex 2-15 for repair with no picture. All voltages are present, battery charging is working fine, motherbord takes about 0,5 Ampers and that's it. I've reprogrammed the bios and still the same problem. They say it might be a problem with graphic chipset but I would like to make sure this chip is faulty before I replace it. Could you tell me how to connect the diagnostic debug card to see what error this card will show me? The KBC is NPCE285GA0DX and I need the pinout of LPC interface to this chip please. |

Ok. I could download this bios file now and I programmed my eeprom but still the same no pictures and motherboard takes about 0,5A without battery. Any other suggestions? Could be KBC faulty? |

Finally I have found the fault. There were two faults in this board, first was the faulty bios and the second was faulty ram memory and that's it. Now after reprogramming new bios and replacing ram memory laptops is working fine. Thank you everybody for help. |
