subject: Have Dell Laptop Ac Adapter Unpluged At Right Time [print this page] For the dell laptop, I have special feeling to this brand. And I have bought a new Dell 300M AC Adapter, because of operation carelessness. Here, show the detailed analysis of the following case to illustrate the "operational details" of importance in order to avoid this bad situation.
Example One: the laptop dell ADP-90FB PA-1900-05D AC Adapter is under the state of alternative current. When should we pull out the AC plug, while the laptop is turned off?
Usually, the screen turned black after we shut down the power. At this point, we often think that has been shut down successfully. People will immediately unplug the dell 2600 PA-6 AC Adapter by hand. In fact, they ignore the light of the motherboard is still on. That means the laptop hasnt turned off completely. if unplug the AC plug at this time, the notebook will immediately switch from AC power state status to battery-powered. At no reason to use the battery for a few seconds, although this does not take much power, this action speeds up the battery more quickly and that makes the battery falling to the initial charge capacity. Thereby, it will reduce the battery charge cycles, affecting the battery life. No AC plug is pulled back, pulling later then? When the board power indicator light turns off (power indicator light still kindle), if not unplug the AC plug, the system's power management program and the battery inside the battery-management chip interface circuit will be automatically transferred to "off state of charge" in 5 seconds.
Above, the correct method of operation is: In addition to the power indicator light outside the bottom of the screen, after all the lights off, unplug the AC plug that with (not later than 5 seconds) like this dell 1525 AC Adapter.
This is the first time that I realize the importance of the time to unplug the dell 1501 AC Adapter. And I believe most people have no sense of this point. And that it why the laptop battery has shortened life span.
