Is there a way to do a manual SMC reset?

Bought liquid damaged MacBook Pro from eBay worked fine when hard started. But power button didn't work. Yesterday I finally replaced keyboard/backlight/ and power button. Keyboard and backlight work great but power button is still unresponsive and I still have to hard start the computer. Pretty sure it's an SMC problem ( trackpad will click not scroll, fans running at high speed). Which I can't reset without a power button to my knowledge. On earlier MacBooks there were spots on the logic board where you could reset the SMC. Unable to find one on this model . I have tried draining the battery disconnecting it and holding power button for 5 seconds then plugging into AC power to bypass SMC ( battery disconnected) with no luck. Also have reset pram erased entire hard disk and reinstalled lion. Is there a terminal command to reset SMC or a spot on the logic board? Or is this just unfixable and i just have to basically leave my computer on always.

Thanks machead3 I was doing that but it still did not work. I was able to start the computer by putting pressure on camera cable pad and then starting with power button. This in turn caused a kernel panel and which afterwards I was able to turn on using power button and I think do a SMC reset. Now my wifi is intermittent so I assume a camera cable connection problem now. Thanks for your reply.

As a work around try using System Preferences:Energy Saver->Schedule to turn on the computer.

Fans running at high speed might be damaged sensors, a hot CPU Use the AHT (Apple Hardware Test) (command-D boot) for that machine may give you a clearer understanding of what problems exist.
