Laptop Disassembly and Processor replacement steps. All this operation require all your attention and your knowledge If you are a little queasy about tearing apart your laptop and replacing the processor maybe this will help. You have to keep in mind that replacing the processor is a risky thing to do. You need:
* 1 Small Flat Bladed standard screw driver * 1 Very Small Phillips head screw driver * Some Thermal compound to put on the new processor. * A mobile Duron processor or a mobile Athlon processor of the "25W Balanced" variety. The processor used in this example is a Mobile Athlon 4 1.2Ghz processor. The processor is probably of the 35W variety. However, the 35W processors do not work correctly in all laptops.
Step 1 Backup all your important things.
Step 2 Take out the batteries and unplug the laptop from the AC adapter.
Step 3 Chose a free area like an empty desktop place the laptop on it then open the laptop and tilt the display all the way back. Place a newspaper or something over the top of the display so you don't scratch or scuff it.
Step 4 You have first to remove the panel that has the speakers and power button on it. It is secured by 1 little screw on the left hand side of the panel. Remove the screw and then slide the panel to the right. With the panel slid to the right you can then carefully lay it on the display.
Step 5 Now you need to remove the keyboard. There is 1 little screw securing the keyboard. This screw is located above the F6 key. Remove the screw. Lift the keyboard by the top, where the Function keys are, and slide it out towards the top of the laptop. Lay the keyboard on top of the panel that is all ready on top of the display.
The Heat Sink/Fan combination is now accessible as well as the harddrive and DVD drive.
Step 6 You need to carefully remove some copper ground straps attached to the Heat Sink/Fan combo . These copper straps have adhesive on them and can be carefully peeled back out of the way. There is one copper strap at the top of the assembly, under the display panel support that is very difficult to remove. Left this strap in place until you actually began the removal of the Heat Sink/Fan combo.
Step 7 There is one small bracket on the Heat Sink/Fan combo by the screw on the upper left corner that is secured to the Heat Sink/Fan combo by another little screw. There is an arrow with the number 3 pointing to this bracket. Remove the screw for that bracket and rotate the bracket out of the way.
Step 8 There are 3 screws securing the Heat Sink/Fan combo to the motherboard. 1 screw (Labeled with an arrow and the Number 1) is at the upper right, the second screw (Labeled with an arrow and the Number 2) is at the lower left, and the third screw (Labeled with an arrow and the Number 3) is at the upper left. These screw are identified on the Heat Sink with the arrow and the numbers 1, 2, 3. Unscrew all 3 screws. The screws will not come out of the Heat Sink/Fan combo. Just unscrew them until the heat sink is free of the motherboard.
Step 9 This is not necessary, but you can unplug the fan power leads from the motherboard. The fan power connector unplugs, from the motherboard, by lifting straight up.
Step 10 You are now ready to remove the Heat Sink/Fan Combo. Remember there is still a copper ground strap stuck to it at the top under the display panel brackets. Carefully work the Heat Sink/Fan combo back and forth to unstick it from the processor and to begin unsticking the copper strap. You will be able to slip the Heat Sink/Fan combo toward the bottom of the laptop and rotate it too the left to get the copper strap off of Heat Sink/Fan combo.
With the Heat Sink/Fan combo out of the way you now have access to the processor and the special ZIF socket that the processor is in.
OK take a deep breath now because this is maybe the scariest part.
Step 11 It's time to remove the processor. You need a small flat bladed screw driver for this part.
The processor is going to slide to the right in the ZIF socket. Put the screw driver in the notch on the left side and begin to apply pressure to the right. The processor will slide about 1/8th of an inch to the right.
Step 12 Before removing the old processor note how it is oriented in the slot. The new processor will need to be oriented the same way. Peel off the plastic cover from the old processor and place it on the new processor. Remove the old processor and place the new processor in its place.
Step 13 With the new processor in place you now need to close the ZIF socket. Place the screw driver in the notch on the right and begin to apply pressure to the left. The processor will slide about 1/8th of an inch to the left. Now you just have to put everything back and you are done. Do not forget to put some Thermal Grease on the processor before you put the Heat Sink/Fan combo back on.
Step 14 Carefully position the Heat Sink/Fan combo back over the top of the processor. Tighten the 3 Heat Sink/Fan combo screws.
Step 15 Plug the cooling fan power leads back into the motherboard.
Step 16 Place the little bracket you removed in Step 7 back onto the Heat Sink/Fan combo
Step 17 Place all of the copper ground straps into their correct locations.
Step 18 Carefully check all of the Heat Sink/Fan Screws. Carefully check that you plugged in the cooling fan Power Connectors.
Step 18 Place the keyboard back into place and tighten down its screw.
Step 19 Place the Speaker Panel back into place and tighten down its screw.
Step 20 Start the Laptop and enter the bios setup screen by Pressing F2 as it begins booting you are successful.

Buying A Used Car Using The Web

by: Louis Rix

When it comes to buying a used car there is nowhere better than the internet to help you get started. There are a huge amount of websites where sellers list their cars along with photos and detailed descriptions and this is the easiest and quickest way to find the car of your dreams. However when it comes to buying the car, there are some things that you should take into account, with this is mind here are some tips for a buying a used car.
Before you even go looking for your car make sure you have a general idea of how much cars of similar age and type go for second hand. Also bear in mind the repair costs of the model, the safety aspects of that particular model and how much the car would cost to insure.
Once you have made contact with the seller and have gone to check the car over, it is essential that you get to see all documents related to the cars history. This will give you an idea of how well the car has been treated and if it has had all the check ups it should have had.
If you are buying your used car from a dealer then you have the right to see the written warranty that is provided by the dealer before you buy, this is one way of making sure of what you are getting before you commit yourself.
When you go to look at the car make sure that you give it a through inspection in good lighting and that you take it for a test drive. Where possible make sure that you test drive the car in most situations, for example up and down hills, in heavy traffic where you are stopping and starting and if possible a brief drive down the motorway. This will all tell you how the car handles and feels and pay particular attention to not only how the car handles but also how the engine sounds.
One of the best tips when it comes to buying a used car is if you know nothing about cars then make sure that you take someone with you who does. If you don’t have a friend or family member then it can pay to book someone from an auto club to go with you and look over the car. While of course this will cost you in the long run it can work out cheaper if the car is nothing more than an old banger.
Always remember that while you can get a good bargain when it comes to buying your used car privately you won’t have any warranty as such as you would get from a used car dealer. So usually you will buy the car “as seen” and this is the risk you take for saving a couple of hundred pounds or more on the car.
Whichever way you choose to go to buy your used car with a little common sense and by following the tips for buying a used car outlined above you can grab yourself a great bargain.
