The use of notebook friends know, although some vendors to you blow the hype, said what computer power can adhere to 7, 8 hours, but really use up, at most 3-4 hours of time, some computers more bad, 2 hours before the warning has appeared, then Win7 32-bit system computer power should be how to use it? The following small series on a number of specific issues for everyone to explain:

First, does the power supply really need to use the electricity and then charge?

Many friends have said that, notebook power needs to be used after electricity and then recharge, otherwise the power is not good, the computer is even worse. So is this really the right thing to say? In fact, the current power is the use of lithium batteries, lithium batteries using the latest technology, in fact, has completely overcome the problem of caching, from life, lithium battery life is mostly fixed, not as we know that will be due to the bad charging and loss, Or the maintenance of good can be used for a longer period of time.

Second, the use of the computer in charge of the need to unplug the battery?

A lot of friends have heard that, right? Is it true that we use the computer to unplug the battery in case of a natural charge? In fact, the above we have said, now used batteries are lithium batteries, after the electricity will be automatically disconnected, no longer accept the injection of electricity, So even without pulling out the battery will not have any effect on the computer.

Third, how to charge to be a good power?
