subject: Still Care The Heat Of Your Laptop Ac Adapter [print this page] Have you noticed that you laptop AC adapter gets more and more hot as you using it. I believe that many people has come across this situation. Some people take it for granted, others take it too seriously. These are normal reaction to this. Personally speaking, the laptop AC adapter needs your attention. Or it might be destroyed by your abuse as my ex-HP 239427-004 AC Adapter. It went to the hell after three months.
As its said that Laptop adapter is a high-precision, high efficiency switched power supply, its main role is to switch 220V of AC power to low voltage DC and provide stable power for the ordinary work.As the power adapter are designed with fully enclosed structure, there is no thermal shell holes, and no internal cooling fan, so the working power adapter is high of the internal temperature. Especially in the hot summer, you are not willing to touch it. Actually the internal temperature is even higher. So in the daily office, entertainment, keep it with proper care and maintenance.
When you use you laptop under the high temperature environment, power adapter should not be placed in direct sunlight and well ventilated place; Do not put the power adapter near the cooling air outlets, otherwise not only the power adapters heat can not be spread out, but also to absorb some heat.
In summer, we can put the adapter aside to increase the contact area around the adapter so that the heat can be disseminated from the adapter. In order to obtain better heat dissipation, we can pad between the adapter and the desktop into a narrow plastic block or piece of metal, to increase air flow around the adapter speed, speed up the adapters heat.
Like this HP 239427-004 AC Adapter, the part number is identical. When you have to change a new one. That really helps you to pick a suitable one.
