Advice 2: How to paint a laptop
Over time, the glossy parts of the laptop are cleaned out and starting to look, to put it mildly unpresentable. To give your laptop a "second life", it is possible to paint it, and then it will gain its original appearance.
You will need
- paint (automotive or any other), sandpaper, screwdriver, clear varnish.
Before painting you need to prepare the laptop. For a start it must be completely disassembled, the paint didn't get on the important elements. The scheme for dismantling of the laptop should be in the manual or on the official website of the manufacturer. As a rule, painted cover and the plastic cover around the keyboard, because they are most susceptible to damage and chipped paint.
Followed by sanding with emery paper finish which is painted. Do not exert too much effort, enough to remove some paint and scratches. Skins better in water or periodically wetting its surface.
After processing sandpaper all parts should be washed and degreased for smoother paint and to avoid bubbles. Then the surface is uniformly primed, and then allow soil to dry thoroughly (at home it takes about a day).
Next is applied a first thin layer of paint. Best suited car paint, but you can use any other. After drying apply another layer.
After drying similarly applied the first coat of varnish and then (about 24 hours) the second. Further, the laptop is again dried. After checking all the painted parts you can safely collect it. Unpainted parts can be polished for a better effect. The painting is finished.
Better to paint indoors, avoiding dust on the wet paint, otherwise the undesirable bumps.
Advice 3: How to reduce the heat of laptop
People constantly use laptop, often face the problem of overheating. Due to the continuous operation of the standard cooling system cannot cope with the amount of heat that is emitted by your laptop. There are several ways to reduce heating.
You will need
- - new paste for the graphics card;
- - tassels;
- - the new cooler;
- stand with built in cooling system.
Install special software that allows you to adjust the time and the inclusion of the cooling system. This method will be very effective if you periodically walk away from your laptop or don't use it. In this case, you must make settings in the system, allowing the computer to go into sleep mode as quickly as possible to save energy and to allocate the minimum amount of heat. For example, use the program Speed Fan, ATI tool or Riva Turner. With these tools you can not only turn on and off the cooler, but in real-time to monitor the temperature of the entire system.
Replace the paste in the cooling system. The paste is a substance that absorbs heat from the heat-generating element of a portable computer and transfers it to the cooling system. Over time, the paste begins to lose its properties. Heat is transferred to the worse, so the laptop starts to overheat.
Examine the repair manual for your model laptop. Also visit the forum of owners for your brand. There you can find instructions for replacing pasta.
Unscrew the bolts securing the body part, which closes the access to the processor. Find clips of processor and expand them. Then carefully remove the processor from the connector. Remove the old paste. To do this, use the special plastic spatula. Carefully remove the remains with a cloth soaked in alcohol or Cologne.
Apply a new layer of fresh pasta. Spread it evenly across the surface. Watch carefully to avoid voids or irregularities. Otherwise, the heat transfer is very bad. Assemble everything in reverse order.
With intensive use the coolers of the laptop is clogged with dust and other dirt. Due to poor air circulation cooling occurs more slowly, which causes overheating. So the coolers must be constantly cleaned. Produce a partial dismantling of the laptopto access the fans.
Disconnect the wire from the cooler and remove the bolts holding the fan casing. Remove the cooler and carefully clean it with a brush. Lubricate moving parts with fresh engine oil. Install the fan in reverse order.
Use a special stand with built-in fans. It is convenient in the case if you constantly use the laptop in one place. This stand connects to the computer using the usb cable. It is advisable to use it with a laptop connected to the power supply, so it greatly reduces the computer power from the battery.
