This is himalaya from micro online in sydney , australia.
the issue you all are facing related to BDOS, Freeze , no boot, black screen. its all related to graphic card for the model 2010 15inch.all these randon issue have will go away after reflow.
This whole production of macbook pro series of 2010 15inch have this issue which is related to NVIDIA GeForce GT 330M graphic card, which needed to be reflow.
I Have fixed 9 of them in last 6 month and 17 of them in last 1 year. some poeple use the heating gun, for them chances of damaing the board is high and fix last for short time only. Here , i use machines to reflow which is more reliable and accurate and maintain the temperatures according to my experience.
