Step 4  Push the mainboard in the arrow direction until it does not move, and lift the mainboard out of 
the N2000H V3 while holding the handle. See step (2) in Figure 5-64. 
 
 
Do not hold any other protruding part on the mainboard to lift it. Otherwise, the components 
on the mainboard may be damaged. 
Step 5  Place the removed mainboard in an ESD bag. 
 
 
Before putting the mainboard into an ESD bag, check that a protective cover is installed on a 
vacant CPU socket. For details about how to install a protective cover, see 5.26 Removing a
