I need steps to replace Fan for my Sony VAIO VGN-S460

Part is MCF-523PAM05 and should be replaced

I can usually give a link to a Service Manual, (Free), jacobjos, but no such animal this time.

Instead I'll give you VIDEO's, lol!

2) Something you may want to look at before you replace the fan,

Fan grinding sound usually comes from the fan that sits atop of the CPU. Get the CPU fan replaced cause the bearings are going bad.

The sony VGN-S460 seems to have an inherent problem with their cpu fans. It is apparent that the fan uses a ball bearing system which over time becomes worn and causes the grinding sound.

The only solution is to replace the entire fan assembly as they are inseparable.

That is definitely a problem from the fan. What you can do is to call sony and check if they still cover Fan replacement for this specific mode.

I trust that you have purchased the entire fan assembly as they are inseparable from the heatsink. You must disassemble the entire laptop in order to remove the fan assembly. they are two screws that are below the motherboard that must be remove in order for the fan assembly to come apart.
If you cannot achieve this yourself, or lack confidence in your ability to rebuild the unit after, you can send the unit to us at www.cowetacomputerstore.com and we will accomplish the desired outcome. We have worked on this system resolving this very issue.

Possible clock timing of CPU is wrong. Is it two fan on this laptop? Maybe one is not functioning. Plus check your power supply if gives correct power!.. If none of this , it comes to the MB and possible a CAPS making problem. Need expert.

cheers

then if that is the problem to your pc then turn your pc upside down and dissassemled the screw at the back then your keyboard should be lift up slightly and if you can not do that on your own try to contact someone in that field to help you but just for you to tell the person that you know what is wrong w2ith the pc the person should try and check if there is anything too close to the fan that the fan is touching and if there is nothing the fan is touching and the noise continue then change the fan with a new one. bye any question again.

check adapter output also may be problem with dc socket on laptop loose or somthing.
