Hints and Tips

 

From Admin
To Organise your Screws when you dissasemble.
Tape two A4 Sheets of paper together along the long side. Place the now large Sheet of paper on the base of Laptop and mark the holes with a screwdriver or pen, undo one screw at a time and tape it to the relevant hole or mark on sheet of paper. Do the same with Motherboard and Top casing. any rear screws can be just set aside. A perfect way to organize your screws.
 

From Paul
Organising and Methods.
Work in Layers, Make sure you don’t block any holes by the motherboard and at all times be aware of electrostatic charges. You should use antistatic wrist straps but you can get away without it. Earth yourself on a metal sink or radiator or if no other means touch the screw on a wall socket then don't move feet, don't work on carpet or socks. Static can zap sensitive electric components. To give you an idea of what Static charge is: Rub a balloon on some fabric then put it close to your hair if you have any you will feel your hair rising due to electro static effect,
now earth yourself and touch the balloon and you will get a mild shock,
that small part of electricity is what does the damage.

Perfect Cooling.
Always make sure you apply heat conductive paste to any heat sync you replace. Avoid the GPU if it has a thick conductive pad. Always Use the Best Paste, its expensive but well worth it. I recommend “Artic Silver 5” paste or better, this paste contains silver and very conductive.
You will notice speed and cooling improvements. Note don’t apply too much as it will work in the opposite effect. The paste should be applied as thin as possible on both Heat Sync and
CPU / GPU but enough to cover the surface.

One way to Remove a Socket Safely.
A safe and easy way to remove that stubborn Socket and to replace it with a nice new one: Trying to remove the socket in one piece can be good for diagnosis purposes but will need a lot of work with a normal soldering iron hence a lot of heat applied to the motherboard and risking damaging components nearby!!. Here’s what you do: Get a pair of Nail Cutters (The Pliers Type) or a normal pair of wire cutters (There a bit big but will work). At the top from the front next to the center pin snip away at the shell (Top) (3 Snips should do it. In doing so you will crack the black shell. Remove as much of the shell that comes free, Start to de solder the Shell, as you will notice you only have to de solder one pin at a time. This way. De solder in this order: Shell left and right pins, Positive Pin (Back on pivot), then the earth pin. Some have more pins but I am sure you will figure it out.

A Better way to remove a Socket Safely.
As Colin mentioned will work very well although crude. I just got my Dremmel today and found it to be the perfect tool. Method: First of all we all know that metal filings are not good if they land on your board and can be hard to get rid of properly so this is what you do: Cut out a piece of solid cardboard 5cm by 5cm (Any larger may be awkward to work with) on the 5 x 5 cardboard cut out the exact size of the socket on one edge. Now very lightly dampen a tea towel (Very lightly, no drips) the purpose of this is to catch any metal filings. So dampen and squeeze as dry as possible. Lay the cloth covering the whole motherboard then place your 5 x 5 card template on top of the towel and around the socket. The template will help you avoid hitting the board should you slip and also cover the space the towel doesn't round the socket.

Check the direction your Dremmel tool or equivalent
(No big angle grinders or drills please) usually this will be clockwise, Angle your cutting wheel
(As small and fine a cutting wheel as possible)
so that the direction is away from your board. Wear Glasses and Face Mask, Cut From Back of Socket towards Front, Medium speed, first cutting the shell apart then gently open the shell away from the plastics. On a much lower speed gently cut the plastics

(WARNING !! Don't generate smoke as some of the non ROHS Sockets have toxins like Cyanide in them Not deadly but could harm your health)

Cut the plastics down to the center pin and stop. De Solder the Shell. You can lift out the plastics (You may have to snip a little to crack it) If all is well you will be left with the pins only. De solder each one at a time. Job Done..

Take Photos and Beware of Clips.
Take photos of each stage of your work, before you remove cables, Organize screws as “Admin” mentioned. Be careful and gentle opening clips as if they break you could be stuffed and have to buy a new motherboard. On Flat cables assume first that clips slide and then some flip up and finally some don't have clips. The ones that flip up are hard to repair. The ones that slide can be bodged if you don't lose the clip itself. Best of all look very closely at the Slots Before you open them, If you cant see how it opens then you need to look closer.
 

From Stewart
Repairing Broken Clips and flat cables.
Sometimes accidents happen. When i get a broken clip and have no way of replacing it i have a clever trick you can use. It takes a bit of skill to master it but it works really well.
Use clear motherboard heat glue (The stuff that you melt with your soldering iron)
or of course an electric glue gun. The right glue is important though.
On Sliding clips you need to find the broken clip or make one yourself wedge it over or under depending on the type then glue it in place. On Flip clips yo need to wedge the cable down and hold it firmly in place as the glue cools and hardens (I use a Blunted toothpick) let the glue cool and snip of the tip of the toothpick.

Another tip if you have a really small flat cable and the socket has come off the board or too damaged. Clean the area, remove the socket if necessary. This bit is the Trickiest but needs some practice The problem being the copper in the flat cable can fatigue and break. Melt the plastic on the top of the flat cable and peal back the plastic revealing the copper track, tin the underside with solder and the tracks on board then line up the cable to the track and solder down from the top. Once satisfied you have a good connection Glue the joint and cable down with heat glue. (Don’t attempt to bridge the cable as it is too clumsy and messy and you will probably fail.
