That would indicate a problem in the BIOS POST not starting the adapter from a soft-off state or a mechanical off state. The key check that I made is that WITHOUT the Windows and drivers installed, the problem still occurs, adapter does not start on cold startup, but if you reboot with just the BIOS installed, the green light will come on indicating the adapter now has power. Check BIOS LAN was enabled, resulted in same problem. Oh yeh, unchecked all the power saving features under power management for network device, resulted in same problem.ġ2. Tested with different Power Supply, resulted in same problem.ġ1. Cold start, no power, but if you reboot from BIOS again, the adapter will turn on.ġ0. Checked the network adapter WITHOUT Windows installed, resulted in same problem. Re-installed Windows, resulted in same problem.ĩ. Checked the integrated adapter, no visual problems. Jumped the Intel ME Engine pins and reset, resulted in same problem.ħ. Jumped the BIOS pins and reset with full power cycle, resulted in same problem.Ħ. Defaulted BIOS settings, resulted in same problem.ĥ. Installed a new CMOS battery, resulted in same problem.Ĥ. Installed the Intel NVRAM update to correct the chipset name of the adapter 82579V from 82579LM, resulted in same problem.ģ. Installed latest driver, resulted in same problem.Ģ. When I startup the PC with the power off (cold start S5 soft-off state), the network adapter will not start and when I check the adapter's properties-details-power data, the current power state will be D3, which means no power provided.ġ. Subsequent boots will keep the adapter working, but if I shutdown the PC completely and then restart, then the network adapter will be turned off. If I reboot or disable the driver and then enable it, the network adapter will then turn on. The driver is loaded but has not started as indicated in the System information. After boot, device manager shows correct name of adapter Intel 82579V (FYI integrated) with yellow marking. Symptoms: On COLD STARTUP during BIOS POST initializing, network adapter will not turn on, no green light. I have been trying to fix this problem for 3 days now with no success. I know sometimes hardware just gets tired. Any suggestions? To my knowledge there were no hardware or software changes that precipitated the failures. Once it does boot, and if the internet connection is working, then it works great. I need to do a hard reset and power it up again and even then sometimes it won't POST/boot. Next, I've noticed that sometimes I'll power it up and while the fans start spinning, it won't POST or Boot. Same with a full shut down, sometimes it hangs and won't power down all the way. Then, a few days ago, I've noticed that when I do a restart, sometimes the computer shuts down and hangs before powering down completely. I've tried swapping cables and ports on the router - I'm pretty sure it's a hardware issue. In addition, sometimes if I just leave it for a few minutes it will reinitialize and come back online. Over the last few weeks, it's gotten worse now even after a restart it doesn't always come back, sometimes taking a few restarts to get it working. I updated the drivers (a few times) with no success. This would usually happen when woken from sleep. A few weeks ago, my LAN port started acting up, intermittently dropping the connection to the router with the only fix to restart the computer. I have a DH77EB Mobo with a Core-i5 that I've been using in my HTPC for the last few years with no issues.
