Tip 1: How to fix a button on a laptop

When using a laptop, you can face the problem of a broken key on the keyboard.The reason for this keyboard can be cleaned with a vacuum cleaner or something else, the key can break off a curious child, but who knows what else might happen.This trouble can be eliminated with almost no effort.
Guide
1
Laptops and netbooks are different, but the keys to fixing them are basically the same.Look at the place where once stood the key and you will see a couple of clips and a pair of slots under the rocker lugs.Rocker - a clamp consisting of two parts which are connected by a hinge in the middle and form the letter "X".It is through rocker key attached to the keyboard.
2
Quite often pulls down with the rocker.In this case, you must first disconnect from the cap rocker keys, set the rocker to its place on the keyboard, and after return to the place and press.To do this, take it (down), separate the latch on one side, and bring mustache rocker of the grooves in the second side of the key.
3
you get two parts: the cover and rocker keys.On the keyboard, you will see three tab for fixing (one large, the other two - smaller).
4
If fixing bent, bend the them in the correct position.Strong attachment does not bend, because they can break and aluminum - then repair more difficult.
5
Replace the keyboard rocker.To do this, get under a large eyelet, get a slight touch of rocker to the two small mounting.After installing the rocker, you can put back the lid and the key - the tabs on the rocker rewound into the slots cap.Here it is necessary to act carefully, try not to miss.
6
Next, make sure that the tabs rocker went into the slots and secure the key in place by lightly pressing on the upper part of it - you hear a click - this means that the key is seated.
7
Large keys (Shift, Tab, Enter, Caps Lock) except plastic rocker may also be in the form of a metal stabilizer brackets for uniform pressing.On the substrate there are a couple of additional keys tabs to secure the stabilizer.In other construction of large keys is the same as that of the smallest.
8
rewound first ends of the stabilizer, then the lower rocker mustache rewound into the grooves, and then put the key in place a light touch.Key "SpaceĀ» (Space) - always the longest.It holds not one, but two rocker and a stabilizer.Install it in place, you can also like the keys Shift, Tab, Enter, and others with a stabilizer.

Tip 2: How to fix a laptop

Laptop is a very useful thing, because it helps to work with important documents, sit on the Internet or just to play games and watch movies.However, he does not depend on whether there is a number of current sources or not: because it is equipped with a built-in battery.However, this is the battery may from time to time and misuse "weaken", discharging much faster than you would like.To consistently failed to carry a charger, repair the laptop, sort out the defective battery.
So look elements of laptop batteries
Guide
1
for urgent repair laptop batteries need a soldering iron voltage minimum of 40 volts, breadboard knife, voltage meter (you can use a multimeter) and new elements.In contrast to the new battery, they are relatively cheap.
2
first fully discharge the battery and then unpack, entering it at a shallow depth in the place of gluing the seam.To do this, use a knife Prototyping.Items you will need to replace and are in plain sight.
3
In order to make sure that all batteries are low, use a voltage meter to calculate its (voltage) value at the input and the output of the elements.Rated voltage for lithium-ion batteries is a value in the 3.7-4.1 volts multiplied by the number of elements, and for NiMH - 1.2 volts, and multiplied by the number of elements.When you make sure that you are discharged, proceed to the replacement of parts.Note that all elements need to replace batteries, not only faulty.
4
Before installing the new elements should also be discharged.Otherwise, the controller can "think" that they are defective or continue their charge until the battery to explode.Discharge elements all at once, and not alone.Connect them in parallel, negative to negative and positive to positive.As "razryazhatelya" resistor can be used to 10-20 W or regular honey.
5
Having started the process to replace, remove old items, starting with those that have a greater advantage.Insert the new elements should be in the opposite order.Instead of soldering is better to use the contact holders, which should be soldered connecting wires.
