Dear friends.
I need a scheme for Lenovo ThinkCentre M72E MB: IH61I VER 1.0
There is a problem with sound. The sound is not played, there is a sign of the disabled device.
I ask the community assistance.

Conducted measurements of voltages on audio codec ALC662. Detected low supply voltage (about 4.4V). Standby voltage 5V normal (there 5.1V). Through what element comes power on the codec?
It was decided to replace the ALC662 codec.

Unfortunately ALC662 codec replacement was unsuccessful. Low-level sound when turned on in the bipper is present, and the audio codec does not see the system.
