If this the type of unit having a switch when you open it. Try to find a switch, commonly it is activated when you open the case. It is just near the edges of the cover, or near to it.

When switched on my pc it will display error messaga . That is "error 912 the machine cover has been removed since last system is start up"

This error is displayed if chassis intrusion protection is enabled and the cover is removed.
But as I remember you can bypass this message and start the computer. I don't remember the key, but try Escape or Enter key. (I think the button to skip this error is displayed below the message).
You can also go to BIOS and disabled Chassis intrusion detection.

The fan may be disconnected or it may be faulty.
Remove the computer cover. check the fan connections and then power up the computer to see if the fan operates. You may have to wait awhile if the fan is controlled by a temperature sensor.

Sony Vaio - How to remove side cover?

On Sonys, you have to remove the top cover first. Look in the back and you will see 2 tabs. Pinch them together and remove the top cover, then the side should slide off.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
