Gateway NX100X Best Budget Ultra Portable Design

The Gateway NX100X is well known for its very low price for such a lightweight laptop,Fujitsu FPCBP80 Battery, Fujitsu FPCBP77 Battery, Fujitsu FPCBP68 Battery, this NX100X is extremely portable and has a very sleek design of 12.1 inches wide and 12.1 inches of display and of course do include a 5 in 1 media card reader. Fujitsu Laptop Battery FPCBP80, FPCBP77, FPCBP68, FPCBP63, FPCBP95 If you are either a home user or a business user and seeking for an inexpensive and ultra portable notebook, then it is very pleasing to see the well beautifully designed Gateway NX100X. The NX100X is built with minimalism feature. One point to be noted with the built of the NX100X is that it has forgone the built in optical drive which is to reduce the higher price tempted on it.


The Gateway NX100X is said to be the Best budget ultra portable design, FPCBP68,as with its cheaper price which is built mainly for the basic home and home based business user’s use, and the NX100X is with sleek black case, brushed aluminum details and with the dark blue status lights. In order to reduce its pricing problem and the sizing problem the NX100X tends to lack two or more important features and hardware follows as the built in optical drive, few multi media controls and of course some of the built in business level security features. But this has succeeded in its best budget and ultra portable design. This notebook is priced many hundreds of dollars less than that of those fully loaded models.


The NX100X do have a 1.2GHz Intel Core Solo ultra low voltage processor which is supported with a 512MB of 533MHz RAM, an 80GB hard drive spinning at 5,400 RPM, and integrated Intel graphics with 128MB of system memory.Fujitsu Laptop Battery FPCBP80, FPCBP77, Fujitsu FPCBP77 Battery, FPCBP68, FPCBP63, FPCBP95 The NX100X’s do possess only a single-core processor to afford its price.


The NX100X is just less than an inch thick and weighs only 3.2 pounds and the dimension of this notebook do complement its minimalism.FPCBP63,The NX100X features only a 12.1 inches wide screen display with a 1280 x 800 native resolution screen, with this NX100X gives out a finer resolution. But with these the NX100X produces the images crisp, the text looked slightly blurred, and the display look as if to be fairly bright.


Then with the keyboard as the screen is bigger keyboard spaced to be better roomed. The typing with this notepad keyboard is not much comfy as it is built with the shallow travel of keys. It is built up with regular but small sized touch pads, mouse buttons. The NX100X comes with only one single power button above the keyboard. Next with the ports and slots of the NX100X considered, Fujitsu FPCBP80 Battery, Fujitsu FPCBP77 Battery, Fujitsu FPCBP68 Battery,there are 4 pin Firewird,Fujitsu Laptop Battery FPCBP80, FPCBP77, FPCBP68, FPCBP63, FPCBP95 and 2 nearly placed USB 2.0 ports and a headphone and a microphone jacks. There is a Type II PC card reader but no Express cards.


When talking on the Networking connections,Fujitsu FPCBP68 Battery, the NX100X do comprise of the modem,FPCBP95 , Gigabit Ethernet card, and 802.11a/b/g Wi-Fi with the optional Bluetooth. Using the USB port the external DVD burner could be attached if you afford one for your must purpose. But when apropos the business level security the NX100X do lack the Finger print reader and a trusted platform module. The battery life of the NX100X is merely of average with 3 hours and 6 minutes with its 3 cell battery. When your usage of the built-in optical drive is less, then the economical choice would be, Gateway NX100X

On the cell phone lithium battery of knowledge

Basically, the current mobile phone equipped with lithium-ion batteries are the batteries, laptop battery so I say below is for the lithium-ion battery charging knowledge. Ni-MH battery is different, here talk about.


1, the basic concepts:


1, lithium-ion battery nominal voltage 3.7V (3.6V), charging cut-off voltage 4.2V (4.1V, according to the label batteries have a different design). (Lithium-ion batteries standard argument is: Lithium-ion rechargeable battery)


2 pairs of lithium-ion battery charging requirements (GB/T18287 2000 norms): First of all constant current charging, ie a current will, while the battery voltage is gradually increased as the charging process, when the battery terminal voltage to reach 4.2V (4.1V), constant change flow charge for the constant voltage charging, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process, continue to gradually reduce, when reduced to 0.01C, that the termination charge.


(C is the control current of the battery nominal capacity of a representation, Fujitsu Laptop Battery
Fujitsu FPCBP80 Battery, Fujitsu FPCBP77 Battery,such as the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not the mAh, 0.01C is 10mA.) Of course, the standard representation of 0.01 C5A, I have here simplified.


3, Why do you think the charge end of the 0.01C: This is the national standard GB/T18287-2000 under discussion is arrived at. There used to be common to 20mA to end, the Ministry of Posts and Telecommunications is the industry standard YD/T998-1999 such a requirement, that is, Fujitsu Laptop Battery no matter how much battery capacity, and stop current is 20mA. GB 0.01C contribute to charge under the fuller, right through the identification of a party manufacturers benefit. In addition, the national standard provides for charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours to, and also believe that the end of charge. (No problem, the quality of the battery, should be within 8 hours to reach 0.01C, the poor quality of the battery, wait and meaningless),


4, how to distinguish battery is 4.1V or 4.2V: consumers do not distinguish between, it depends on batteries manufacturers product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is basically 4.2V, but there are exceptions, such as Tianjin is the power of God 4.1V (but also by a 4.2V).


5, the 4.1V to 4.2V rechargeable batteries for what will happen: will increase battery capacity, feels good to use, standby time increases, but will shorten the battery life. For example the original 500, reduced to 300. Similarly, the 4.2V of the overcharge batteries, it will lower its short-lived. Lithium-ion batteries is very delicate.


6, since the battery inside a protective plate, we can rest assured it: No, because the shield is the cut-off parameter 4.35V (this is good, the bad to 4.4 to 4.5V), protection board is to cope with the event, and If each overcharge, the battery will soon decay.


7, much of the charge current be appropriate: In theory, the smaller the battery the better. But you can not order a battery charge, etc. 3 days bar. GB provides low-magnification charge is 0.2C (standard arbitration charge), but also to the above-capacity 1000mAh battery, for example, is 200mA, Fujitsu FPCBP80 Battery, then we can estimate only the battery out of more than 5 hours to charge saturation. (MAh = current capacity mA × time h)


Identification of national technical supervision departments lithium capacity, based on high-rate charge of 1C to 0.2C of low discharge rate in order to calculate the capacity value of time, test number 5 times, there is a second volume to reach end of the trial. (That is, 5 times the opportunity to pass if the first test, and the back four times not do) to detect prior to allow a pre-cycle, is to 1C constant-current charge to 4.2V to stop, but not behind the constant pressure to 0.01 C, the process, much less 14 hours.


8, lithium-ion batteries can withstand much charge current: factory tests can be high, but the elevation of magnification the provisions of the country 1C, also to the above battery, for example, can be filled with more than 1 hours. Such a large charge current, battery can bear do? For the current lithium-ion batteries, is only a mere trifle.


There are no national standards on the charger, the implementation is the Ministry of Posts and Telecommunications industry standard YD/T998 1999 / 2,Fujitsu Laptop Battery
Fujitsu FPCBP80 Battery, Fujitsu FPCBP77 Battery, which provides for the current charger not more than 1C.


9, life is what provides that: it simply refers to the battery through the N sub-1C charge, 1C discharge, the capacity dropped to 70% at this time,Fujitsu FPCBP77 Battery, N is the life span. Not to say that 300 times without being able to use their 301 can not be used in. GB provides life shall not be less than 300 times. We are usually not detected when the conditions for the use of such a harsh, life will be longer.


Having said that the concept (do not bother, there are a lot did not say), finally it can be said of the charger. So long chargers currently on the market situation is like?
