DIY repair for notebook Sony Vaio F-Series
Two Sony notebooks (vaio f270 & f-305) with commonly known shutdown problems sometimes recognised as "motherboard defect", "hibernation
shutdown", "intel pentium mobil processor bug" I was happily able to fix, by simply changing ten bypass condensators on the processor board.
Although the original condensators measure 180uf
epcos type "tantal low esr" 10v 100uf size="d"
obviously work perfectly as a replacement and the higher voltage rating makes temperature derating an issue of lesser interest.
The yellow little bricks on the picture above are the new ones.
Make sure to disassemble in right order to get access to the condensators on the processor board (unplug mains and remove the accu):
Upper shell with loudspeakers (2 screws, connector)
Keyboard (1 screw, connector)
Front shell with touchpad (5 screws, connector)
Heatpipe with heatsink (5 screws)
LCD display (10 screws, connector)
Power-on-switch board (2 screws)
Heatsink with fan (3 screws, connector)
After having replaced the condensators, put some heatsink compound on the pads and reassemble.
Good luck and happy working,

With the information provided above it will take you only few hours of work and a few bucks to fix your notebook, for _m_e_ it did cost
Many calls with narrow minded sonyists
Some hassle in coordination with the parcle service
A non neglectible amount for a wrong diagnose (defect motherboard)
A second notebook for comparison
Some month and intense investigation in the www
Uncounted tries and failures
It would be helpfull to have some experiance with electronics anyway an owning some sufficient tools for proper
working with such small components
no resposibility for all the above...
