Although the notebook computer that has become a mass consumer electronics product has many advantages such as carrying and using it than the desktop computer, if you want to find the shortcomings and shortcomings of this kind of electronic product, you can still find out a lot of feelings for users. I think the shortcomings, and the most dissatisfied users here are the battery life problem in the laptop battery mode, because almost all laptop products when using the battery, the short battery life has become a recognized common problem for consumers. ".
There are a lot of reasons for the short battery life of laptops in battery mode. So, in the initial stage of purchase and use, what aspects should we know and circumvent in advance ? Especially in those who will shorten the battery life of laptops. Under the factors, what should we do to maximize the battery life of the laptop ?
Microsoft Vista into a notebook "stealing power culprit"
Whether the software product will affect the battery life of the laptop in battery mode has been controversial, but this problem seems to have no suspense now, because not only through the previous Microsoft operating system " ACPI drive BUG power consumption" to make this controversy There have been results, and with the widespread adoption of Microsoft's Windows Vista operating system, the conclusion that software products can shorten the battery life of laptops is irrefutable.
Recently, some foreign media reported that because the Windows Vista system needs to open the Aero Glass 3D user interface during the actual running process , it indirectly or directly increases the power consumption of the notebook. To put it bluntly, it is because the use of the Aero Glass program requires continuous system. The work can be reflected, and then the CPU , graphics card and display unit continue to work under heavy load, so that the laptop needs more power to meet the needs, and if it is in the battery-powered mode, the most direct result is a large Shorten the battery life, Vista's "beautiful price".
In fact, from the day Vista was deployed to laptop products, its high power consumption has been a concern, but now this concern has been upgraded from ordinary consumers to many laptop manufacturers, such as HP and Lenovo. Such well-known notebook manufacturers are quite dissatisfied with this. It can be seen that in the future, while we focus on hardware to save energy on laptops, Microsoft should also "steal" the notebooks from the software side.
Microsoft's operating system is recognized as the largest power consumer on the first notebook platform. While "recommending" Microsoft to optimize and improve this, the more direct question is how many software products will become notebooks in the future. "Battery killer" of computer battery or "roadblocker" on the road of energy saving of notebook computer products !
Why is the battery life time not allowed?
Looking closely at the product advertisement information of various notebook manufacturers, it is not difficult to find that the battery life time is not ambiguous, that is, how long the battery life of the notebook is boasting, but in actual use, the notebook is in the battery mode. I can only know how long it is. Only users can understand that this is a kind of irony in the promotion and use of notebook products. So what are the reasons for the laptop’s inaccurate battery life in battery mode? What ?
For the user, like the mobile phone product, the notebook computer is not accurate in terms of battery life, and the value given by the manufacturer is accurate, especially in the user's actual use mode environment, those nominal 4 hours or 10 hours of battery life has always been a "short check", of course, we can not say that the manufacturer is deceiving, but should open to see what the "official life time" given by the manufacturer is based on which test Environment, this is a very important aspect, because the same model of the notebook is based on the battery power of different battery cores, different test environments ( such as temperature and humidity, etc. ) and different system environments ( such as a single memory or dual memory and screen brightness) Etc. ) Different test results will occur under different test factors, so we should look at the battery life given by the manufacturer.
In addition to the manufacturer's own test of the battery life has too many "technical colors", in fact, the specific book under the same model will be very obvious due to the difference in "physique", configuration and user's later use environment. The endurance time becomes a value that changes at any time, and this value can only be reduced and cannot be added.
Here, we should condemn two aspects of the laptop's battery life time: one is that the battery life given by the manufacturer is based on the battery pack with a higher number of cells, but the actual product for the consumer is low. The battery pack of the number of cells, but does not explain ; another is to provide consumers with inferior "original battery."
How to maximize the long-term work of NB
As everyone knows, even if you just increase the brightness of the screen of the laptop, add a memory or insert a mouse expansion card, it will shorten the battery life in the battery mode, so it is very realistic: laptop battery The life time problem will always become people's helplessness, because at least there will be no qualitative change in a short time, then we really can't do anything about it . We can only watch the original three or five hours of battery life reduced to one. Two hours ? The answer is of course no.
First of all, unless it is necessary, we should try not to use the laptop in battery mode, it is best to use it in the mains environment, especially for those who have worked with laptops for a long time, don’t hope The battery of the laptop can bring you much convenience, even if your notebook battery can last more than eight or nine hours.
Secondly, if you can, in battery-powered mode, it is best not to use too many peripherals or functions of the laptop. For example, if the environment or conditions permit, it is best to minimize the brightness of the display and unplug the mouse. Touchpad, turn off the built-in network card or audio system, etc., in order to maximize the battery life, must be "sacrifice", although this time using a laptop is a bit painful.
Finally, the old-fashioned advice, prepare one or two spare batteries for your laptop, which is the most sensible and effective solution for those who often use battery life.
In the context of existing notebook battery technology products, it is still a dream to get longer battery life, especially when the lithium-ion battery technology products are still dominated, but there is no quality upgrade, laptop The battery's wide range of “breaking ten ( hours ) †on the battery life is still far away.
