Lenovo Thinkcentre Edge E73 overview 

I've got the e73 and needed to format it and reinstall Win 7, but this time I'm not able to enable the frontal integrated speaker, I've tried all WIn upgrades, looking for drivers, I even disconnect and reconnect the 39k5012 cable but nothing seems to be working, the system doesn't detect that Mono_Out is connected or something like that, If I connect headphones they sound without issues but not that speaker, anyone that could help me on this??? THX

Is it possible to remove the build it in speaker and if i do so will it improve airflow

My E73 does not have a TPM and Yours does not have it too. Do u know how to get one?
