My Sony Vaio PCG-FRV37 is running very hot (and has unexpected turned off several times when running CPU intensive applications). I've read that other people have had this problem and that cleaning off the dust inside the computer helped. I've remove the 7 screws from under the the computer, 2 from the back, and 2 from the battery compartment. However, I cannot seem to open the case. The top seems to be coming off on the bottom near by the touch bad, but in the middle near the keyboard it will not move. I thought maybe I needed to remove the keyboard, but there is no obvious way to do this. Does anyone have any suggestions on how I can get this computer open?

Thanks!

This is the third post in like 2 months, where a Sony Vaio user coudnt get there computer open. Everyone has that same problem, i think Sony should have a PDF guide to opening it for all you people.

Sony bites. They don't publish any technical info on their laptops. The solution is to never buy a Sony again. If anyone has the PDF file of the service manual, please post it somewhere and provide a link.

There are actually 9 screws on the bottom that need to be removed. Some of them are deep seated. Each hole has a little arrow pointing to it.

There is also a screw under the front RAM socket that appears to need to be removed and one under the small bay cover on the back of the bottom.

But even with these out, it will not come off...

You can also follow the instructions for removing the HDD and DVD-RW at http://vaiorepair.tripod.com/ but even with all that stuff out of the way, it still won't open.

However, with all that stuff out, and the battery out and the floppy cover off (the small plastic cover on the side by the memory stick reader), you can actually get it pretty clean inside.

Mine still is overheating though...

i think it was something about a screw hidden near a USB port.

Actually, there is a scrw hidden near the usb ports, but i can't believe that that's it - unless that lets you remove the screen. The keyboard is somehow locked down on the top. On an older Vaio that I had, I had to slide the keyboard up towards the screen in order to disengage it.

Curious thing: There are also 3 screws located on the back of the case, under the screen hinge. If you look closely you can see them, and they appear to be normal case screws, but there is no way to remove them without removing the screen.

My hunch is that the speaker cover must somehow pop out and let you access some screws there.

Hello everyone,

So I was working on my brothers’ pcg-frv37 Sony vaio and trying to clean the fans out. I was taking more and more screws out and still no hope in sight of getting it apart. I even removed the front cover of the LCD screen then those 3 screws under the monitor that are impossible to get to. I have about 20 screws out and no way to get it open then I got it. Are you ready? It is so easy it will p**s you all off.

So the speaker section above the keyboard pops out. Then you then you can remove the screw holding the keyboard in then all the screws you need to get to are right there. Once you get the face plate off you can see the fan assembly. unscrew it and pull it out. My cpy was attached to the fans so be very careful not to damage it. You must then detach the cpu without hurting it open the cpu slot and insert the cpu and close the slot. You will probably want to get some thermal paste because the old stuff looks whacked out. Back to the fans you remove them from the heat sink and can see the wall of dust deep in the heat sink. A combination of tweezers and a vacuum or can of air should get you back in shape. Then put it all back together. I know I am a genius. Hopefully this post will help others in working on these damn Sony vaio's that are one hell of a pain in the ass to open.

How did you pop the speaker section off? Do you need to wedge a screwdriver under the plastic?

Thanks.

Yea I used a screw driver and started at the hinge section. It is hard and you feel like you are going to break it every second. You might want to get some cpu thermal paste cause it will need more since it has been running hot for so long.

If you are interested in the service manual for the PCG-FRV37 go to the following address and you can download the PDF file.

http://mzdelivery.homeip.net/delivery/files/XSP375.zip

Once you download it you just have to unzip it.

Good luck

The link for the manual is not working. Do you have a different link.

Thanks

Hello,

I went through the steps above to replace the fan and that worked fine, but now the computer will not turn on. The battery light blinks and then the power light, but it does not boot up. Has anyone else encountered this? Thanks.

I had this same problem. You're going to have to take the heatsink back out and remove the CPU off of the heatsink. Use a flathead screw driver and just gently pry the CPU off. When you have it off, look on the mother board where the CPU usually fits. Use the screw on the side of the CPU base to 'unlock'. Put the CPU down and it will set all the way down. Now turn the base to lock. You can now assemble the heat sink again and put everything back together. You're suppose to use some heat transferring glue to re-adhere the CPU to the heatsink, but I did not have any on had. Hope this helps someone else.

Cleaning Sony Vaio PCG-FRV37

Check that you’ve got a fully charged battery. Unplug the laptop & remove the battery pack.

The speaker section (black grill + the whole blue cover across the width in one) above the keyboard pops out. There are 4 spring loaded clips along the keyboard edge, accessed from between various function keys ESC, F5, F11 & DELETE they all need releasing (push in a few mm with a bent paper clip), preferably together or sequentially from one end, then the speaker section levers up from the keyboard edge.

Then you then you can remove the screw holding the keyboard in then all the screws you need to get to are right there. Once you get the face plate off you can see the fan assembly. Take note of which screws came from where as they are not all the same length.

Disconnect the 2 fan leads. Unscrew the 4 captive screws and pull the whole heat sink assembly out with a straight(ish) vertical lift. The CPU fitted in a ZIF socket is paste bonded to the copper block in the central region of the fan assembly, so be very careful not to damage the pins as it is forced out of the locked ZIF socket. There’s no other way, as the ZIF release is hidden by the fan assembly.

Check the CPU, all pins should be grid aligned & upright, Note there’s 1 or 2 pins missing at one corner, corresponding with the ZIF socket alignment corner– if any pins are bent or broken, then it’s been damaged as you pulled it out & you’ll need to get a replacement. Also check the ZIF socket for damage – or broken pins left behind – hopefully none, but if you’ve been unlucky, then this is probably where those missing pins are & they’ll need to be removed before a replacement CPU is inserted.

Detach the CPU without damaging it, - may need to carefully scrape off the dried on excess paste along the sides of the CPU block (i.e. the 2 mm gap between the pcb & the fan assembly copper block. Then gently slide & prise the CPU heat sink block from off the copper heat sink of the fan assembly.

Open the ZIF socket ˝ turn anti-clockwise, insert the CPU in the correct orientation, close the socket with ˝ turn clockwise & clean off all the old paste using isopropyl alcohol (IPA).

Remove both fans from the heatsink. Clean out the wall of accumulated dust from both plenum chambers using tweezers and a fine brush. Clean the fans & copper block using IPA & cotton buds to get rid of all the dust. Use a vacuum cleaner fitted with a very fine nozzle – homemade using heat shrink tubing works ok & get rid of all the fine lint deep in the heat sinks. When they are clean you can see light through the both sets of grills. Re-fit both fans to the assembly. Clean the copper block thoroughly using IPA.

Using fresh thermal paste (silver loaded is best) use a very small amount & scrape a thin film across the CPU and another thin film across the copper block of the fan assembly in the central region where the CPU mates.

Reassembly of the laptop is the reverse of taking it apart. Power it up again, if you don’t know that you’ve got a good battery pack, use the mains lead. - I hope all is well.

I finally opened my Sony vaio PCG-7171L , before to turn it off open the cdrom because there is two screws hidden under it and other ones are hidden under the battery.
My laptop is turning off at the slightest movement, I think it's the CPU (either generating a lot of hot or not integrated correctly in the motherboard)
is there anyone having the same issue that can help me please.
thank you
