Check the PCH start sequence, if you find the Plataform reset signal (PLTRST#)is highly possible that the PCH works fine, if not, check the PCH start sequence backwards to try to find the problem. All the power supplies are ok ? The system clocks are ok ? Good Luck

Check in power on sequence witch one signal is not present, If u don't have osciloscope check voltages on quartzs, better than nothing. What about voltages on coils? all ok? |

Topicstarter, an oscilloscope is highly recommended in such cases, try to find it. Are you sure your CPU is good? These CPUs are known for their frequent fails. Also install 100% working RAM module. Can you tell us pre-failure conditions of your laptop? I'm advicing you to see is there any activity on BIOS flash pin 2 and LPC LAD0. Does BIOS you've flashed contains ME region? However, are there any hot chips? EC, LAN... |
