After a long time I had nothing interesting to repair, four days ago a neighbour brought me an Acer Aspire 5520 completely dead, nothing happened pushing the power button.
So I have disassembled completely the notebook and with an hot air gun, I have warmed up the board slowly, than I have heat only the Nvidia chipset at around 220°C for about 30 seconds and than I left the board to cool down.
The result is that the PC is repaired.
Here two pics, one with the chipset highlighted and one with the hot air gun I have used and in the background the working notebook.
