No chance, other than a company who specialises in recovery of data from dead HDD's; expect this to be very expensive if possible. However...there are some people on here who claim replacing the 'power IC' is possible, but I still haven't seen a single case on here where that's been successful/a motherboard replacement hasn't been required to fix (the normal fix).
Search for similar threads, someone posted here recently somewhere where you could buy the part.
The other issue is, if there's other components dead on the NB, you're going to have to end up replacing it at anyway, so you run the risk of 'double paying' for the fix if replacing this individual component doesn't work (and assuming you can even find a repairer who will attempt this for you).
If it's important enough to cause you grief if it's lost, back it up. No excuses

If you don't know how to recover if things go wrong, what are you doing flashing custom roms ?
