How to Fix Cisco Solid Green Syst LED light No Connection No Console
The Problem:
I have a Cisco Switch 3750e. The Syst Led is solid green after reboot. It was working fine untill it was rebooted.
The Cause:
It is the hardware, the memory component.

A temporary fix?
Open the case and remove the heat sink.
Use a hot gun to heat up the memory components for about 5-10 mins. This will “reflow” the solder connections on the chips.
Here is more info if you would like to read.
Good luck!
