If this is the late 2008 MBP, then it will have the NVIDIA GeForce 8600M GT video chip. You may well have the NVIDIA problem:
The Apple Store has a specific test for this problem. If you have it, the repair will be done at no cost to you.
Anyone know what the blinking light codes mean. I've spent hours trying to figure out. You would think Apple could document it somewhere. My 15" late 2009 unibody is not starting on power up and I've tried everything. I get slow blinks from the suspend button that repeat, the DVD drive starts and then quits each time it blinks.
see http://support.apple.com/kb/HT2674 and http://support.apple.com/kb/HT2341 for some information about beeps and flashes.
In your case, though, jinnes, the slow blinks suggest that the computer is simply refusing to wake up from sleep.
One possible, though unusual, cause of this can be if you are using the computer with it stacked on top of a macbook. In this case the magnet in the macbook underneath activates the Hall effect switch in the MBP, making the latter think the lid is closed, and preventing wakeup. I've had this happen to me and it is quite unnerving at the time! Simply moving the MBP will fix it. see http://support.apple.com/kb/TS2917
The same effect could be generated by proximity to other magnets.
It is also possible , if this is not your situation, that the hall effect switch in your MBP is actually defective. It may be worth trying simply opening and closing the lid a few times to see if you can get it to activate.
