Dead Sony Vaio PCG-631M laptop - power block problem.Help!
 

I have Vaio laptop. After checking the power block it's appeared that
power voltage comes into the board and there's also first conversion of
voltage from 16V to 5.99V. No other values on parts. It's too
complicated and small to analyze PCB so I'd like to ask for any
solutions to repair it. Does anyone have a source to some diagnostic
manuals or have any idea what can I do. Thanks for answers like "throw
it away". I'd like to try to fix it.
Also I'd like to ask for a tip how to "decode" part values of SMD
elements as they're coded.
Thanks in advice.
