subject: Notebook Lcd Screen And Battery Keeping Ways [print this page] Q: the battery unused for long periods, it should be how to save?
A: Charge or discharge to about 40%, and then placed in 15 to 25 degrees Celsius temperature, dry place, the temperature is too high and too low are likely to accelerate cell aging.
Q: laptop battery is not removed each time with the power you?
A: It does not matter, notebook batteries have protection circuitry, full of will not continue to charge the battery.
A: If you have been in frequent use of the battery, then this is the battery aging, which can not be avoided, you can only be considered for a new battery and replace the battery or batteries; If your battery unused for a long, may also lead to this phenomenon, this time the need to completely discharge (can not start until the date), and then full power, repeated several times to activate the battery.
Right now people are buying more and more notebooks, of which there are some first contact with the novice and even laptop computers to simply not going to work for newbies. New machine hand, there is always a novice another look ridiculous to the old user questions to ask, of course, some of which used the laptop for a long time people still do not know the problem. Therefore, the purpose of writing this notebook to those novices to clear all the doubts with the machine first.
First, why the bottom of the screen look darker? Mainly from the brightness of the LCD screen installed in the lamp on the rear panel LCD, LCD screen brightness is directly dependent on the number and brightness of the lamp. The number of desktop LCD lamp at least two, higher brightness of the screen and even the root can reach 4-6;PACKARD BELL EasyNote Minos GP2W Battery and notebook computers are power and volume constraints, only a lamp and smaller, and more placed on the screen rely on the central position, the lighting, limited in scope, so there will be lower than the upper Shaoan, more obvious in the phenomenon of two scraps. So long as not a great contrast, that is normal.
Second, the connection part of the LCD screen will be hot?
Many novice much heat for this part of the tension that his election to a laptop LCD screen problem. Actually not the case, laptop LCD screen coil were placed in this position, and ignition coil is a major component of the circuit and the power coil, and the work of heating coil power circuit and the introduction of middle school physics textbooks to be involved.
Third, why use the battery the screen will squeak sound
This issue needs to be explained in two ways:
First, the battery-powered, because of the role of notebook power-saving features, the entire notebook circuit voltage is in constant change, and then power through the screen, the coil in the coil current is constantly changing in , but this time the sound frequency emitted high-voltage loop is involved in high school physics. Electromagnetic shielding if the laptop is poor, the sound will be heard by the user, so we say that some of the technical foundation of this phenomenon in the weaker brands of laptop computers is common, the actual response to the power adapter a lot of friends will happen voice also this causes.
Second, the sound may be high-frequency noise, the sound and the voice of one of the above is the biggest difference will be high-frequency noise is a maddening sound, I believe that friends are listening to the sound some experience. The sound is generally motherboard design flaw, if the situation is relatively common, vendors will release a BIOS update to resolve this issue documents, such as the recent IBM T40, HP NC6000 there are different degrees of this problem, manufacturers have also released a new BIOS for solution PACKARD BELL EasyNote Minos MGP00 Battery.
Fourth, the screen shows that the layer of plastic sheets can be torn off it?
This layer of plastic sheets placed on the main purpose of the process of shipping and display LCD screen is scratched or is dirty, and when you have to buy it back home after the mission of this layer of plastic on paper even if accomplished, usually pay attention to the habits that can, or you will face every day, and the screen less reflective screen would work, but also affects their appearance.
Painful to tell you password, if there is no internal data or hack to get passwords. considerable trouble. As for why manufacturers set a password, there is a high-sounding reason is that their high level, do not want to allow users to easily change the parameters inside to protect the battery safety.
In fact, this is nonsense, how can there be so many general users of professional equipment, even if there is, probably will not use. More important reason is that if it is easy to repair, manufacturers will be high after-sales service that customers? Set point obstacles, we are making money. You can go to DELL and Lenovo curse well, since they are inaudible.
If the maintenance engineers really do not have the password, but also can not break, there is a way for! Chip for the control circuit, the brain and spinal cord were removed, and give you a full exchange PACKARD BELL EasyNote Minos MGP20 Battery , which the head office now.
It is possible, in most cases no problem, almost more than costs incurred, the chip price is not high, the maintenance of honest business encounter, are embarrassed to tell you to mention the money. Of course, there are not enough, because too complex, this depends on the level of maintenance engineers and the complexity of the circuit.
