Disassemble CM1150V
My CM1150V recently got knocked off my desk. There is now a rattling sound inside and it won't power on. I figured I'd take a shot at opening it up to see if I might be able to fix it myself. Does an...

I'd expect a loose heat sink to cause trouble after some time has
passed, and the (now-detached) device overheats. I would not expect it
to cause immediate "won't power on" (which is a bit vague).

The heat sink has plastic pins with springs on two diagonally opposite corners. On the other two diagonally opposite corners there is a metal pin that appears to make contact with a solder point. Because of the missing spring pin one of those metal pins is not touching the circuit board. I suspect that's the reason for lack of power. I'm not sure what is vague about "won't power on." When I plug it in and turn it on the device does not indicate it is powered up (i.e. the power light does not come on).

You can see it better than I, but I wouldn't expect a heat sink to be
used for a power connection. You can run the experiment, but my
expectations would be low.
This is all low-voltage stuff. I'd try to hold loose stuff in place
by hand before putting much effort into manufacturing replacement
plastic pins.> [...] I'm not sure what is vague about "won't power on." [...]
To someone, that could mean that it doesn't respond as expected.
"the power light does not come on", on the other hand, describes an
actual (non-)event -- no interpretation required.
