The symptoms are high fan speeds
I have these problems with my mbp 15" mid 2010. Last four digits of the serial number is xxxxxxxxx-RAGU. the logic board number is 820-2850-A.
The symptoms are very high fan speeds. Does not respond normally to power button. Only boots into emergency mode.
No lights under keyboard. date and time are not set properly. indicator light flashes every 2 seconds.
Tried resetting/flashing SMC through shell but didn't work.
Please let me know where the smc is I would love to replace it and get this computer working. Thanks for all your help.
Is this a good question?
