Sony VGN-CR series laptops develop a common problem of abnormal shutdown.It seems to be heating problem but after cleaning or changing the heatsink,CPU and fan problem remains the same. Affected models are:

 VGN-CR11GH VGN-CR12GH VGN-CR14GN VGN-CR22G VGN-CR23G VGN-CR24G VGN-CR26GN VGN-CR32G VGN-CR34GN VGN-CR35G VGN-CR36G VGN-CR37GN VGN-CR313H VGN-CR323 VGN-CR343N VGN-CR353 VGN-CR363

This problem is related to motherboard and needs a chip level repairing.Some times laptop can work for full day but it shuts off without warning and time is not fixed when machine will shut off.

I have 100% solution for this problem and repaired atleast 50 Sony VGN-CR series laptops.
