This video is about troubleshooting the overheating problem in SONY VAIO Laptops by cleaning the heatsink, applying the heatsink compound and cleaning cooling fan.
I found we can remove the fan blade easily by pull it softly. I wash the fan blade under water before put it back. Thanks your vdo for guiding me how to fix it.
I bought a Core i5 model VPCF131FM with no support or info online matching it, came with GT310 and dual core 480m processor. Upgrading to Core i7 four core as many online seem equipped, it turns off randomly, no dust, some noisy fan but no excessive heating to the touch, still, going to have to downgrade again to two cores....i7 hopefully; the 620m I have and used on Asus B53J model successfully
Thanks for this video - I can concur that this DID cause my GPU to fail :-( started getting high speed fan and display glitching, now it wont power up - so for the sake of cleaning the fan I'm now replacing the motherboard. Its such a good machine i'm not going to bin it!
I've encountered no screen anamoly but backlight normally an LVDS issue, on a ROG751 spendy Asus laptop, now there's no POST and just fan and power pilot light before shut down and it appeared GPU fail due to it's side fan not operating consistently, which is a tip to definitely look out for before you bin your mobo ...or brick it, as they say
Thanks for the video! I have a question - Is it compulsory to apply a new layer of thermal paste when replacing the fan? Or can you simply remove the fan, clean heatsink/fan/vents and then screw it back on? Thanks!
Odds are that the paste condition is part of why it overheats. And if you've already torn it down, then it should be dirt cheap and fairly easy to clean it off and apply new paste.
Nice Video...I tried the same, unfortunately as thermal greese sticks firmly with the cpu,when i plug out the heat sink from CPU without unlocking my processor, pins got damaged...So to the viewers while removing heat sink from CPU unlock the CPU ,take the processor out from the socket along with the heat sink and then try seperating heat sink & CPU...Fortunately i could align processor pins by using knife moving along entire rows and column....
My tip for glue like cement HSF assembly, always wiggle sideways at first, use precision screwdriver to pull up each side the same, like equal unscrew force and taking turns on each of four Normal screw allotment
Is it OK to just add more thermal paste (on top of the old)? In most videos I've seen, they invariably take cleanliness to a religious level - completely remove the old thermal paste, and then add fresh paste.
No not really. Leaving the old thermal paste on can cause thermal issues in itself and is just plain lazy. As is blowing from your mouth (wet) to remove the dust buildup on and around the heatsink fins. That's not to say that it's not an improvement in this case as the fins were pretty damn choked. My suggestion would be to first make sure to use a grounding strap so you don't go zapping anything with a static charge from yourself or environment. Then a you can use some fine tweezers to remove the larger bits of dust. And to finish off, a softer brush like say artwork brushes and some compressed air, either from a can or an airbrushing tool if you have access to one. And obviously, blow the dust out from heatsink not through it as you'll just push it further in. Cleaning the old thermal paste off with some Isopropyl Alcohol (>95% is best) and cotton buds or lint free paper towel. Remove any old thermal pads too if that's what was used (you can see this in the video he didn't remove it) as that could cause air gaps and ill fitting heatsink later. Don't use too much thermal paste, usually a small blob about a third to half the size of the heat plate is right. Any more and you'll end up with a mess to clean up next time round. And don't smooth the paste down. Putting the heatsink back on gently and apply a small amount of pressure will spread it out and ensure good coverage and contact with both surfaces.
