Its a wierd problem... actually it might be the heat radiated of your CPU.. if u're sure that this is not the reason, then chk whether the place where u've kept the kbd gets heated even if the keyboard is not kept there.. if u wanna open ur kbd, u must be careful.. first of all lemme tell u that though it is a simple process, i'm in no way responsible for anything that happens when u do it if u do things other than what i say.. i'll tell u how to do it if its ok for u.. send me a mail..

Keeps restarting itself

It could be an overheating issue. Are there any error messages that pop up when it turns off? Try touching the bottom part of the computer, do you feel any heat or something like that?
Try booting to safe mode and observe if it does the same thing inside safe mode. If it does, then you might need to replace the fan or clean the interior part of your computer.

How exactly to clean your laptop

Cleaning laptop case Cleaning the exterior portion of the laptop case can help keep the laptop looking new. The exterior case of a laptop can be cleaned by using a damp cotton cloth that has been dampened with water. It is not recommended that the exterior case of the laptop be cleaned with household cleaning solutions. However, if there is a substance on the laptop that cannot be cleaned with water, we suggest using rubbing alcohol.
Cleaning case openings
If dust, dirt, hair, or other substances are in the case openings, it can prevent air from getting into or out of the laptop. This can cause the overall heat of the laptop to increase, and in some cases may also cause such issues as random reboots.
Look for laptop openings where the laptop draws in cool air from outside or blows out any hot air from the inside of the laptop. These openings are usually on one of the sides, the back, or the bottom of the laptop. Dust, dirt, hair, or other substances can almost always be removed easily using a cotton swab and/or compressed air.
Warning: If you're using compressed air to clean the openings that have fans within them, it's possible that the amount of air blown on the fans can cause them to over spin, damaging or destroying the fan. To help prevent this issue, place something in-between the fan blades, such as a toothpick.
Cleaning laptop keyboard
Like almost everything else on a laptop, a keyboard is also different from the standard computer keyboard. With many laptop keyboards the keys cannot be completely removed. Therefore, we suggest cleaning the keyboard by using the same damp cloth you used to clean the exterior case of the laptop. In addition, compressed air can be used to spray any dust, dirt, or hair from in-between the keys.
If you've spilt something onto the laptop keyboard (like a soda) that's causing the keys to stick and cleaning it does not help we suggest that you have the laptop repaired since the keyboard cannot be replaced.
Cleaning laptop mouse (touchpad)
Cleaning the laptop touchpad can help improve the look of the laptop and also many times will help improve the responsiveness of the touchpad. To clean the touchpad surface, use the same damp cloth used to clean the exterior of the laptop.
Cleaning LCD display
Additional information about cleaning LCD and flat panel displays can be found on our main cleaning page.
Cleaning internal laptop components
Cleaning the inside of a laptop computer can be a difficult task. However, in some situations, it may be necessary because of excessive dust and/or dirt buildup within the computer, such as on the processor's heatsink.
Unfortunately, however, because of the complexity often involved in disassembling the laptop to reach many of these areas, Computer Hope cannot provide this information online for every laptop ever made. If you believe after cleaning your computer that it is still overheating because of dust and/or dirt buildup, we suggest taking the laptop to an authorized repair center.
Other cleaning information and help
Additional information and help with cleaning other portions of computers as well as discs and other computer related peripherals can be found on our main cleaning page.

Advent 5712 overheating and cutting out, why

Step 1:
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Laptop fans are designed to keep the system cool by removing heat from the hard drive, processor and other internal hardware components. The fan draws cool air in, then blows hot air out through vents in the laptop case. A faulty laptop fan can cause permanent damage to occur very quickly. If a laptop fan starts making loud noises or stops blowing hot air through the vents, replace it as soon as possible.

Turn the laptop off and unplug it. Unplug or disconnect any external drives or other devices. Move the main battery latch to the "Unlock" position and remove the battery pack. Push in on the optical drive release mechanism, then pull the CD/DVD drive out of the case. Remove the screw(s) that hold the hard drive sled in place, then pull the entire hard-drive assembly out of the case slot. Turn the laptop over. Remove the screws on the bottom that hold the keyboard assembly in place. Flip the laptop over then open it. Lift the front of the keyboard up about 1 to 2 inches. Unplug the flexible ribbon cable that connects the keyboard to the motherboard, then pull the keyboard assembly away from the bezel. Lay the keyboard aside. Unplug the laptop fan. Remove the screws that hold the heat sink/fan assembly in place, then remove the fan from the laptop. Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

Instruction to replace CPU Fan on Toshiba Satellite C655D-S5048

How about a pictorial disassembly guide instead, Bill?
Click on the photos to enlarge.

Page1::Page2::Page3::Find another model,
is on the top, and bottom of the page in White.

Just in case you need to get into the Display Assembly someday,

Ignore if you are aware;

1) Wear an ESD wrist strap. (Electro Static Discharge)
Your body carries Static electricity.
Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.

Wear an ESD wrist strap, and have it's alligator clip attached to a good ground source, and your laptop is safe.
Average cost is $3 to $6.
One example,

Don't use an ESD wrist strap, and you can use your laptop for a Frisbee, or expensive doorstop.

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
I feel an Anti-Static Mat is unwarranted. (I can elate on that if you like)

You can connect to a large metal serving tray (Unpainted), and set it on the table you're working on.
Or perhaps a large metal knickknack. (Unpainted)

The CPU is the most susceptible computer hardware component, to Static shock.

Use a multi-compartment container for the various screws you will remove.
SOME screws look VERY similar to other screws.
Advise do NOT mix them up.

The Keyboard Cable STAYS attached to the Keyboard. It removes from the motherboard connector.
The Keyboard Cable is a FFC. Flat Flex Cable,

Flat bar terminal strips are used. NO plug connector on motherboard side.
The Keyboard Cable MUST be reinstalled in the original position.
Even if from the factory it is flopped over, twisted, or going to Hawaii for vacation. (What?)

For this reason you may wish to make a mark on one side of the cable, and a matching mark on the same side of the motherboard connector. (Sharpee?)

The Keyboard Cable's motherboard connector is a type of ZIF connector. Zero Insertion Force.
It is composed of two rectangular pieces, but does NOT come completely apart!

The Bottom rectangular part is larger than the Top rectangular part.
The Bottom part stays stationary to the motherboard. It is the BODY.
The smaller Top rectangular part is movable. It is the Locking Bar.

The Locking Bar wedges the FFC cable of the Keyboard, into the Body of the ZIF connector; when in the Closed/Locked position.

The Locking Bar type for your laptop, I have deemed the Sliding type.
It ONLY moves about 2mm to Unlock. (That is a little more than 1/16th of an Inch)

IF, the Locking Bar is broken, or the Body is broken; you are looking at MOTHERBOARD REPLACEMENT, and why I am being so detailed with this.

Thumbnails to move the 'tabs' of the Locking Bar. Or if necessary a hard plastic tool. NO metal tools. One slip and damage can result.

Top Cover has Tabs going around the perimeter, of the inside edges.
These snap into matching Latches on the Bottom Cover.
I use a thick guitar pick to start separating the covers, then follow with my fingertips.
A computer Spudger Tool is also nice to have,

Tool only needs to go in about 1/4th Inch.
Can't insert tool in parting line to separate case halves?
Move over a little. You are at a Tab/Latch.

Just thought I would throw that in.

For additional questions please post in a Comment.

Has two channels on the sides, to slide down into a channel formed in the outside edge, of the laptop Base Enclosure. (Bottom Cover)

Wires are soldered to it. Two of them. If there is a Red wire it goes to the Center terminal on the back of the jack. The Center hole is the Positive connection.

The Black wire goes to the outside terminal on the back of the jack.

Use good de-soldering/soldering skills. Do not make a cold solder joint. (Solder connection)

There are no exact Service Manuals listed for the Sony VAIO PCG-41217L Notebook PC. (It is also part of the VPCSC series. It is a VPCSC31FM)

However after you disassemble 100 laptops, or so; you find disassembly of all laptops follows a basic pattern.

This shows me different key views of the laptop. I have also opened a separate window, with the User Guide from Sony eSupport.

The Ebay link shows detail of the Palm Rest Cover.
Shows it to be one piece with no separate Switch Cover.

(Switch Cover: Flat plastic strip above Keyboard, and below Display Assembly.
Usually has the Power On button, LED indicator lights, speakers, etc in it)

Also shows me a Bottom View.

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Lay the notebook on a clean, static free cloth, on your table.
Helps protect the table, and the laptop from scratching.

Lay the notebook bottom side up, Battery Compartment facing away from you.

Use a multi-compartment container, and label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws. Advise DO NOT mix them up.

You should be wearing an ESD wrist strap, and have it's alligator clip attached to a good ground source.
Average cost is around $3 to $6. Do not wear it, and/or connect to a good ground source, and when you are finished you can use your laptop for a doorstop.
Static 'kills' computers.

Example of an ESD wrist strap,

I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case. I feel an Anti-Static Mat is unwarranted.

You can set a large metal serving tray (Unpainted), on the table you're working on, and connect to it.
Or a large metal knickknack. (Unpainted)

You are going deep into the laptop, and the Static sensitive Processor, and other hardware components could be 'zapped'.
Use ESD wrist strap.

All screws are removed from the bottom of the laptop. All around the perimeter (Outside), and the inner ones.
The optical drive (CD/DVD drive) will slide out.
After the optical drive is removed, look to see if there are any hidden screws on the outside edge of the laptop, that may have been covered by the optical drive. Remove them if so.

Remove the Harddrive.
Remove the Ram Memory.
Remove all peripheral components. (Dummy PCI card, etc)

I don't know if the Palm Rest Cover removes on this model, or the Bottom Cover. (Base Enclosure)

Bottom Cover removal style,

Yes. The bottom cover access panels are different than yours.
Posted for Keyboard removal, and Bottom Cover removal.

The Keyboard Cable STAYS attached to the Keyboard. It removes from the motherboard. There is NO plug connector on the end of the Keyboard Cable.
The Keyboard Cable is a FFC. Flat Flex Cable,

It ONLY plugs in, in one direction. Must go back the same way it was originally. Even if it was originally twisted.

For this reason you may wish to make a mark on one side of the cable, and a matching mark on the same side of the motherboard connector. (Sharpee?)

The motherboard connector is a type of ZIF connector.
Zero Insertion Force.
It is composed of two separate pieces, but DOES NOT come completely apart.

There is a larger rectangular Bottom part. This is the Body, and it is stationary. Mounted to the motherboard, and doesn't move.

There is a smaller rectangular piece on Top.
This is the Locking Bar.
There are two styles presently used;

1) This style slides. Slides up towards the LCD screen.
ONLY slides about 2mm. That is a little more than 1/16th of an Inch.

A) Closed, or can be said as Locked;

B) Open, or Unlocked;

The Locking Bar is barely seen on top, and the sides. The 'tabs' of it on the sides, are eased towards the LCD screen, with the thumbnails.

2) This style flips up,

A) Locked;

2) Unlocked;

IF, the Locking Bar is removed from the Body, it is broken; or the Body hinge pins are broken.
EITHER way means MOTHERBOARD REPLACEMENT, and why I am being so detailed. Use care.

Here is what the Keyboard looks like,

Put your mouse in the middle of the photo, and slide to the right side of the Keyboard.
See that half-moon tab sticking out, that looks to have a threaded hole in it?
Screw comes up from the Bottom of the laptop, and goes into this tab.

Looking closer at the open laptop view of the Keyboard, it almost looks like the Keyboard is under the Palm Rest Cover, and cannot be removed until the Palm Rest Cover is removed.
May just be the view, or my eyes.

That is about as far as I can take you.
Post the problems you run into in a Comment, and we'll try to work them out together.

How to Open a Winbook Si Laptop

The keyboard is fairly easy to get off. At the top there is a plate that covers the switches; on the left there is a tiny hole that you use a paper clip to push down gently and unlock a catch (like on a CD-ROM drive door). While gently pushing down, slide the entire cover to the right, and then lift it out. This will loosen the top edge of the keyboard; lift from the top edge and push toward the screen, and the tabs at the bottom edge will slide out of their sockets. The keyboard mylar flat cable will have some sticky stuff on it, so be careful when lifting the keyboard not to tear the keyboard cable.

Once you get the keyboard off, you can also remove the CD-ROM drive (two screws, silver and black).

To get at the hard drive, which comes out of the top of the case, from under the keyboard palm rest, you take out the battery, and the three screws on the bottom side of the case nearest the front edge. Then you can pop off the black keyboard palm rest below the keyboard. Be careful to not damage the cable connecting the touchpad to the mobo; it has a little plastic connector. The HD has three screws holding it in, including one on the adapter that attaches the IDE connector to the mobo.

Hope that helps

Spilled Grape Juice

To give it a good cleaning, you will need to remove the keyboard and clean anywhere you can see juice or feel stickiness. You can buy the expensive computer cleaners, but I suggest 50/50 rubbing alcohol and Q-tips. Remove the battery and C-mos battery to make sure there is absolutely no power to the machine what so ever. After cleaning inside, you will want to give it a good 24 hours to dry, ensure that there is no moisture before applying power. If the juice reached the bottom of the machine, you may need to remove the screen, split the cases, and take the motherboard out, in order to clean the bottom side of the board. If you leave juice anywhere on the board it will gum up, and the acids in the juice will corrode and detierate the circuitry on the board causing a motherboard failure. Now the keyboard, in order to thoroughly clean the keyboard, I suggest that you spray a good amount of the rubbing alcohol in the keyboard, shake it or blow it out with air, then take paper towels and daub up the rest. Repeat this two or three times, then let it dry approx 24 hours. Sometimes the keyboard won't recover after a spill and will need replaced. If it works properly, then, after using the keyboard for a while, you will notice if any of the keys are sticking. Take the sticky key or keys off and clean them individually. I know it's alot of work, but it'll teach you not to keep open drinks around your laptop. It did me, I've ruined one machine, two keyboards, and thoroughly cleaned a third very expensive machine of mine to keep it working, but I finally learned to drink from a sippy around my laptops.
