With netbook becomes more and more popular, we have seen a similar trend of netbook development just like that of laptop before. Although it comes to have provided more convenience to users in portability, net play and even practice, which has converts these mini laptops into a brilliant mobile device. However, as to the external parts of netbook like AC adapter, we can figure out some differences between netbook and laptop beyond we expected.



People who have used netbooks can learn that they have developed well in functions and performance as well. For this reason, even if the laptop battery is not so powerful, it can extend the standby time much longer than it should be, so is the AC adapter.

With smaller size in appearance, AC adapter for netbook seems to be different from a normal one, laptop power cord in particular. There’s no denying that only an interface with smaller size can be available to this new “laptop”.



As to AC adapter, I am confused if netbook requires lower charge time or it just cannot bear such a speed of charging. HP 510 AC adapter, a 65W compatible laptop charger, is only at the standard level in specifications of output voltage and current. However, even if the interface has been changed, it still is so powerful to the netbook for these advantages in charge.



Whether it is a problem for AC adapter or laptop power cord, I think the primary contributor to users should be the development of netbooks themselves. It is better to improve the performance, internal circuits and functions than searching for a suitable part to these backward “laptops”. Of course, we should still take efforts on environmental protection while it has really reached the certain level of technology.

Nowadays, saving plan has become a hot topic for this special period. Meanwhile, many related problems, such as health insurance, unemployment and retirement have changed the market a lot, especially in the pattern of consumption. As to consumer electronics, I decide to recommend you a saving plan for HP AC adapter.

Compared to other laptop brands, compatible HP AC adapter seem to have a wider range of compatible laptop models. HP Compaq nc6000 AC adapter, for example, can be used in 100 laptop models or more for its specifications and internal components design, which is more than double of others. That is to say, one can be used in several computers with only a little money spent on it.



To save money, if one of your HP AC adapters comes to be damage, you can take use of a compatible adapter after checking its specification. As a matter of fact, even if the laptop is out of work, we don’t need to throw the whole away for some parts can be used in the next one, HP AC adapter included. In the past, it is a HP 510 AC adapter with 65 W and 3.34 Amp. After checking, I find that it can also be used in some other Dell Inspiron and Latitude laptops.



As is well known that AC adapter needs to have a rest frequently for its high work temperature. Normally, we have to prepare for a replacement to trade off. And according to the principle as above, we learn that we don’t need to cost any money on replacement only if the former one can be used normally.



Furthermore, if your work computer is accidently in the same list of AC adapter, such as that of HP Compaq nc6000 AC adapter, we can share it in both office and home. Even the Dell laptop can use it as a resource of power energy.



Actually, saving has happened to us in all kinds of details in our daily life. Only observe carefully can we save more expense from all aspects.

As laptop charger works by alternating current, it seems to be mysterious for users to learn about its principle and features. Especially in the black box, we just don’t know how it achieves the transition from mains supply by laptop power cord to certain value of output power.



Even so, users seem not to pay more attention to the maintenance of laptop charger. The improper operations, such as putting the charger into the laptop bag only few minutes after powering off, are harmful to computer. Among all electronics, charger and some other laptop accessories are more sensitive that any malfunction in details will influence their performance.



Then how dangerous it will be if we forget to unplug laptop charger for a long time?

If we forget to remove the charger from both laptop and external power supply, it will continue to work. Although the laptop is power off, the charger will continue to provide power energy to laptop charger and some components, about which I have ever argued with my colleague. I think although there’s protection circuit in battery, it will begin to charge again as long as the capacity comes to a certain value. For this reason, the recharging circles will be reduced rapidly.



If we forger to unplug laptop charger from external power supply only, it will harm less to us. It can be exemplified by HP 510 AC adapter. As it is designed with an additional function of standby mode, if it doesn’t work for some period, it will enter this kind of situation. At that moment, the working power is lower than 0.5W which is insignificant to laptop charger and safe to users.



However, it doesn’t mean there’s no defect for us to keep laptop charger in outlet, even if it is of low power like HP 510 AC adapter. Actually, it is a waste of energy to do like that for consummation in internal resistance, laptop power cord and some other components. Furthermore, all work and no play are still not so good to these parts. Therefore, you’d better remember to unplug your charger a few minutes after laptop power off.

Have you ever found that the light your laptop AC adapter is still on even if it is a few minutes after powering off? Do you think it is caused by some power energy still stored in the laptop power cord? Actually, the adapter is still on work with external power supply and laptop battery when the computer has been turned off.


If we unplug AC adapter immediately when powering off, we may be at risk of burning or laptop damage. Although it is cut down, some components are still working with power consumed. The process of cooling down is about 10 seconds to one minute. Once unplugged, these internal components will be forced to close and also data loss.


For this reason, as the internal system is closed later than the external devices, such as LCD screen and the indicator light, what we should do is to keeping the AC adapter plugged until they are all done. At the moment of power off, there’s still some force of inertia inside the laptop. Actually, in the process of shutting down, the internal components are working to help the programs closed or updated. That is to say, only after the screen is died out, the components come to finish their work.


One day, HP 510 AC adapter was complained by a user who has just bought it for only a month. He said that what he owned was a bare computer. He would like to get a high output power compatible charger to improve the laptop speed. However, after a month, he found his HP laptop become hotter and slower. He was confused how could it happen while he was careful in use.


After examination of our experts, we found that the internal components were injured by his improper way of AC adapter. After work, he was always so eager to make appointments that he removed the AC adapter from laptop immediately. Therefore, the components have experienced of closing forcibly for nearly a full month, which is really dangerous to him.
