Summary You can calibrate the lithium-ion batteries on iBook, PowerBook, MacBook Air, or MacBook Pro for optimal performance. The battery has an internal microprocessor that provides an estimate of the battery power consumption during battery charging and discharging. Battery needs to be recalibrated from time to keep the battery time and percentage displayed on the screen accurate and to ensure the highest battery efficiency. You shall execute this p

From another point of view, pram is a small part of the NVRAM.The contents of the data stored in NVRAM and pram vary depending on the model and operating system content. On PowerMac architectures, the content is much more than the Intel architecture. At the beginning of the advent of the Intel architecture computer, the NVRAM was almost empty (at least, I checked it 1.5 ago). And now there's something in the NVRAM in the Intel-architecte

and be aware of downloading the latest system software from the software update program. Apple sometimes releases system updates that can significantly improve the laptop battery. · Your notebook computer needs to be used frequently, and it is mixed to charge and out of power. Apple does not recommend that you always plug your laptop into the charger. The ideal scenario is to use the laptop on the train and then recharge it in the office. · If you use a desktop computer at home or in your off

ibook, PowerBook G4, MacBook, or MacBook Pro, you can calibrate your battery by referring to the Apple's Chinese (Simplified) guide. The steps for other Macintosh laptops are basically the same: you need to have enough battery (keep it up), then disconnect the battery and use it out of the power until the system automatically sleeps. During this time period, do not charge. After that, you need to recharge the batteries until the battery is full, and

to a large monitor than two working simultaneously. The Mac notebook also offers a "close-cover Mode": The feature introduced from PowerBook G4 can be combined with a notebook's own screen, working with an external screen alone (of course, since the notebook is closed, the external keyboard and mouse are required). After you close the screen of your Mac notebook, you only need to connect an external monitor, a power supply and a mouse ke

Java input/output (IO) performance can be elevated using standard buffering classes, just as the operating system increases its speed by buffering requests. For example, if a piece of code requires reading data from a disk, it tries to read the data that is already in memory, and if the code wants to write something to the disk, it might store the output in memory for a while before it completes the write operation to wait for more data. In a Java IO system, writing one character to memory is m

If you have a PowerBook G4 or ibook, you may be able to use the power button to allow the computer to run out of shutdown, reboot, or allow the Mac to go to sleep in the dialog box. But don't think this is a laptop-only privilege, and a desktop Mac can do the same. As Scott Kelby in his book Mac OS X Killer Tips, you can do this simply by using the media exit key on the keyboard (the key to the upper right corner of the keyboard that is usually used

MINI-VGA is a video interface that is used to replace standard VGA on laptops and other systems. In addition to its tight composition and output VGA video signal, the MINI-VGA port also adds the ability to output AV terminal signals and s-video signals by expanding the display identification data (Extended display identification data). Today the Mini-dvi interface has replaced MINI-VGA for most applications. Most of the MINI-VGA are used in Apple's Ibook,emac, early models of
