Hi, 
I was trying to backup my camon 11 cf7 using wwr tool and sp flashtool. When I got to the memory test stage,  sp flashtool should have given me the option to untick all leaving RAM test but it didn't.  What I got was DRAM ticked by default and auto and manual mode. So I left it in auto mode and continued the test but the results I was seeing was different so I clicked on stop and disconnected my phone.  It is now totally dead.  I've been charging for about 4hours still not responding.

Hold the power button for 2mins at intervals and see if it comes on.
If it still doesn't come on, you have to open (disassemble) the phone, disconnect and reconnect the battery connector.

I took it to a technician and he disassembled and reconnected the battery and charged it. The phone turned on successfully and he charged till it was fully charged.  When I took it home I placed it on my desk and about 45 minutes when I took it,  the phone was off again.  This time, when I connect to PC,  it makes a sound.  Sometimes it doesn't.  When I try to turn on,  it vibrates but nothing happens

Charge it again with original charger,then observe it again.

This is a hunch; your battery may have been switched, but be sure.

try charging the battery like @emmanus suggested
you can try holding vol / power button button before connecting the charger to the phone
