Lenovo laptop power adapter fever how to do

Issue Time:2006-09-22
In fact, the power supply is normal, so don't worry. When the power adapter is in the process of voltage transformation, a part of the electricity is converted into heat to cause wear and tear. This is the law of physics and cannot be solved. If it is hot, it can be blown with a fan.

The function of the power adapter is to convert the power supply into a note. In general, it is turned into a DC for notebook use. The converter has been working after the computer is turned on. As long as it consumes energy at work, it is converted into heat, so it will be very Hot, especially in summer, is especially noticeable, so try to put it in a well ventilated place.

Power adapter heating solution:
1. Select switch components with small voltage drop and low loss. The heat dissipation area should be as large as possible. The switching power supply above 100W should have a metal perforated casing or a cooling fan.

2. Try to place the power adapter in a place with good ventilation and heat dissipation. Never put anything like a book on the power supply.

3. When using the notebook in a high temperature environment, place the notebook power adapter in a place that is not exposed to direct sunlight and ventilation; do not place the power adapter near the heat dissipation air outlet of the notebook, otherwise the heat of the power adapter will not be dissipated. Go out and absorb some of the heat.

At present, the power adapters on the market are sealed with fire-resistant and high-temperature plastics, and the heat generated inside is mainly transmitted through the plastic casing. Therefore, the surface temperature of the power adapter is still quite high, and the temperature may even reach about seventy degrees. The power adapter is inevitably hot, but it can speed up its heat dissipation and prevent its temperature from rising.
