MacBook Pro Heat Issue (A challenging problem...)


hi, long time reader first time poster. if post in wrong section, apologies in advance , may mods move somewhere more appropriate. try cut issue short possible:

1 day realised 2011 15" mbp wouldn't start. through series of coincidence, trial , error , luck worked out if put mbp on heat mat few minutes. (thus gently warming bottom of machine) press button , turn on without issue.

so, when power button pressed mbp doing temperature check , deciding, wrongly, temperature low , won't turn on. heat unit bit, heat test , well. (at least assume that's happening)

there way can fix this? maybe turn off heat test on startup? , if so, how? have tried search issue elsewhere , can't find else same issue. genius bar stunned bizarre development. wonder if many people have issue , won't turn on, person loony enough try heating bottom of unit...

things have tried:
- resetting pram nvram etc
- new battery (since needed 1 anyway, , genius bar suggestion)
- wiping , reinstalling scratch
- searching on google issue

met extreme gratitude.

many thanks!
 

did apple confirm "temperature check" before booting? i've never heard of that.

power connection wonky , expansion heat completing it.
