how to buy a laptop battery

Notebook keyboard with a Chinese label
Many friends and some media tests in the evaluation room will say so and so ’s keyboard feel to how , in fact, this is the most difficult to measure word of . Laptop keyboard key way short compared to typical desktop keyboard a lot ,IBM Laptop Battery in itself is very uncomfortable. So do not feel too good . And each person the flexibility of software and hardware for the keyboard keys have different preferences , so simply use their own feelings of how to handle the keyboard is not objective.
A good laptop keyboard , in order to :
1, foot clearance , the following ordinary 12 -inch notebook , IBM ThinkPad A20 Battery, IBM ThinkPad A20M Battery, IBM ThinkPad A60M Battery, the keyboard often with tight design , the distance between the close button , playing word uncomfortable .
2, key prison , some bad laptop keyboard keys , according to a corner , another corner or even turn up to , so playing word , key rickety , it is difficult to bear.
3 , the overall level , notebook keyboard, thin , often installed with the following notebook memory , hard drive and other accessories , laptop keyboard below the design of some irregular in some places there are accessories, some areas are empty , plus the keyboard itself is lined Thin , when typing the bottom where there will be no settlement accessories feel not only uncomfortable , or even felt by fall, according to the horrors of bad feeling . Those from low- angle head-up the past , or even see the keyboard is a wave -shaped , very smooth . This keyboard is more frightening is that books high temperature work , the keyboard will muster up a little , but together on screen after shut down , summon the keyboard has not returned in situ , but friction LCD screen , resulting in LCD screen And keyboard layout printed on the same scratch and can not repair, will also affect the warranty . As very serious consequences .
4, poor layout , lack of a small number of key notebook keyboard , where it is compact, so the keyboard layout is different, some very unreasonable laptop keyboard layout , a number of function key settings all over the place , hard to find ,IBM ThinkPad A20 Battery, IBM ThinkPad A20M Battery, IBM ThinkPad A21M Battery, type and use of Inconvenient time . I used a WIN button to move to the upper right corner of the Toshiba laptop ,IBM ThinkPad A20 Battery, and it felt extremely awkward the .
5 , configuration - smoke and mirrors .
Smoke and mirrors of the notebook configuration Single
Many friends often ask me, certain types of notebook memory frequency is the number , how many rpm hard drive , motherboard chip , etc. What is the specific configuration, this really is powerless , unable to answer. Now the notebook production , due to the arrival of the upstream parts manufacturers are inconsistent , while the production line can not be expected to stop work , so basically without violating the commitments and below the configuration information based on the use of existing parts to assemble . So if you encounter the low-end notebook hard drive to install the 4200 switch to early arrival for high-end books are not installed to 5,400 RPM drives , and high-end books have been produced on the line , only a thin disk , then the 4200 RPM drives will be installed to High-end notebook , the lower end of the late 5400 books but were using high-speed hard drive . Memory also do so. This will give the various batches of different products , the configuration may change phenomenon. For there is no public commitment to the hard disk speed , memory frequency and size of the notebook motherboard chipset , manufacturers can make a configuration according to the actual circumstances of adjustment , for consumers, could feel a headache , but in the absence of a better solution Until that time, only as far as possible subject to the actual configuration of the spot , in particular,IBM ThinkPad A61M Battery, the configuration should not have to listen to media evaluation , and to its commitment as a manufacturer .
6 , the battery - how can how long?
Laptop battery life is a big problem , if not the battery ,HP Mini 1001XX battery, We have to notebooks do, do not buy a desktop LCD computer such as what to buy books , to have a mobility. Then use the standard battery is it? Under what circumstances how long regarded as normal? The so-called maximum life time , standby time are what mean? Now the notebook computer , the basic is the use of lithium batteries, the benefits of the answer is very clear . However, the number of cell batteries , laptop power saving mode configuration and the circumstances of the battery are greatly affected . In general, a laptop , the battery is fully activated case, at full speed under the circumstances , should be able to ensure supply of more than two hours to be normal . IBM ThinkPad A20 Battery, IBM ThinkPad A20M Battery, IBM ThinkPad A21M Battery, To note thatLaptop batteryThe life of the battery charge and discharge by the number of very serious impact . Therefore, to minimize the frequency of battery charge and discharge , for extending the battery life of notebook computers is very good .
7 , lower frequency - it ye on the down- out?
Using Speedstep Pentium M processor energy saving technology
Some of our friends in the purchase of laptops equipped with mobile processors when there are often plagued by a problem that is often not achieve the nominal processor frequency , IBM ThinkPad A20 Battery, the frequency is always lower than the nominal speed of operation , some Friend on his laptop that is a problem , in fact, this phenomenon is not much tension . As the notebook product is different from desktop processors processor , notebook processors for these energy-saving considerations, most used , such as INTEL ’s “Speedstep” and AMD ’s “Powernow” technology energy-saving technology , the processor can be used by state Analysis automatically reduce the frequency of use, so as to achieve energy saving. If the status of the use of low frequency words , use your influence , you can turn off the power saving features inside the BIOS to set the options and to adjust the Power Options properties has been open, so even in the Battery case , the processor will run at full speed , of course, battery life will shorten the response , after all, can not have both fish and bear’s paw Well .
