Hello i have a Lenovo M5400 DA0BM5MB8D0 Rev. D when i connect the AC adapter the Power LED is blinking 3 times, and THAT is ALL. It will not power ON, or do anything! I have 3.3v on power button, i have 3.3v and 5V on motherboard. Also tried to Flash 2 versions of BIOS (both EC and KBC). not shure but i think is a bios problem. if anyone has WORKING and TESTED dump, please share. |

I advise you to check the startup sequence. Or refer to the service center. |
