subject: Save your laptop from overheating condition [print this page] It's commonly known that the heated part of the laptop is the outlet of the fan. In addition, it's not ignorant that the AC adapter is the most heated part while the laptop is in use. this is very obvious. Thus we seldom pay attention to the heat of the adapter unless it got in trouble. I used to worry about my HP ED494AA#ABA ac adapter, because this one is a replacement of my laptop adapter. I was cautious of the quality. I bet most people have the same problem.
Usually, after three or more hours working of the laptop, this ED494AA#ABA ac adapter would turn hot. My hands feel uncomfortable while touch it. as we all know that laptop AC adapter is a high precision and high efficiency switching products. It can switch the 220v to lower voltages direct current. It can provide the laptop stable power for the laptop, that is why it is called the power source of the laptop.
As the power adapter is a work in-house high-voltage, high current switching power supply under the state, work load more weight, and is fully closed structure, no cooling holes on the shell, also no internal cooling fan to assist, so the power adapter work, the internal temperature is high. Especially in the hot summer, touching the surface can feel the hot; the internal temperature is even higher. So in the daily office, entertainment, make it proper care and maintenance.
When I used my laptop in a comparatively high temperature, I placed the ED494AA#ABA ac adapter on the side way to form it an angle from the ground by a card. The sunlight and other heat source should be kept far away from the AC adapter. In other way, place the adapter in a cool place so that it can dissipate the heat. Otherwise the heats not only the power adapter itself cannot be distributed but also absorb the heat nearby.
Thus if there is certain smoke or strong smell, you should be alert that there might be some risk to continue use it again. You should unplug the adapter and ask experts for help. It s not expensive to get a new AC adapter as my new replacement works well.
