Ever since I purchased this C460, it has been nothing but a challenge! I have a brand new motherboard, awesome.. but the PC wakes up on its own. I have Wake On Lan disabled on the BIOS, Network cards (including WiFi) and keyboard/mouse.
But it still wakes up and gives me a boot error 1962 No Operating System found. But if I restart, it boots to Windows fine.
I am extremely disappointed that not one Lenovo tech in Malaysia nor Philippines can resolve this issue. Furthermore, I have to repeat myself many many times regarding the issue.
Mr. Yang Yuanqing (CEO) will be very displeased when he reads my formal letter. This PC is an evaluation before making a huge purchase order. So far, this is having a negative effect.
Solved! Go to Solution.

Sorry to hear about your trouble on the C460 system.
I don't have a C460 available here for testing but can you look into the BIOS > Power Tab and ensure that ErP is set to Enabled.
From this thread:
"Enabling ErP will disable waking from full power off state with anything other than the power switch. With ErP disabled, it's possible to set your computer up to turn on with a click of the mouse or with a keyboard, or with a packet sent to the NIC. It has no effect on waking from sleep.
The purpose of it is environmental. When powered off, your motherboard makes sure it has just enough power to receive a power on signal from it's connected devices. if ErP is enabled the motherboard allows itself to full power down."
