Best Use Guide for Apple notebook batteries

　　As long as you pay more attention, you can add long battery life, that is, the battery ran out and need to recharge the time before. In addition, following these guidance messages will give you the overall effect and long-term optimization of your laptop battery.

When your battery is exhausted (meaning the entire battery is depleted, not limited to this use), your battery time will be significantly shortened (e.g., from the past four hours to less than 10 minutes). Apple, which is now on sale, is designed to keep the original reserve power above 80%, even after charging 300 times, under Apple's advice. If your battery time is too short, you can choose to buy a new battery.

The best thing to be aware of is that you should use your laptop at the most appropriate temperature. In summer, remember not to lock your laptop in the car. Apple laptops can be stored at temperatures of -25°c ( -13°f) to 45°c (113°f), but should be used at 10°c (50°F) to 35°c (95°F) temperatures, while the best use of the temperature is 22°c.

　　When you first buy a notebook:

· Have plenty of your batteries 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 office, and you don't use your laptop very often, it is recommended that you thoroughly exhaust and fully fully battery, which should be done at least once every month. You can add a hint message in ical. (Based on predictive information, this hint is expected to be in the system beforehand in the Mac OS X v10.5 "Leopard", which the computer may automatically remind you of.) )

　　Calibrating the battery

Calibrating the battery regularly and regularly will keep your battery in place for long and effective use.

If you have a ibook, PowerBook G4, MacBook, or MacBook Pro, you can refer to Apple's Mandarin (Simplified Chinese) guide for battery calibration.

The steps of the other Macintosh laptops are basically the same: you need enough batteries (keep them on), then disconnect the battery and unplug it from power until the system sleeps automatically. During this time period, do not charge. After that, you need to recharge your batteries until the battery is full, and don't power off the time. After that, the battery calibration process is basically over.

　　Long-term preservation

If you don't have a plan to use your laptop for the next six months, Apple advises you to remove and keep a battery full of 50%, and if you save a battery that runs out of power, the battery may fall into a "deep discharge" state, leaving it unable to retain any power. If you keep a battery that is fully charged, the battery may also appear to be discharging and will not be used again in the past. Be careful to keep it at the right temperature when you are saving a battery that is 50% full.

Older laptops, such as the Macintosh portable and the early PowerBook 100-generation laptops, use lead acid (PB-acid) batteries. Within 2-3 months, it should still have enough power to use the laptop. In 12-18 months, the battery can still inject new electricity. Please note that when this type of battery is completely discharged, there will be a chemical reaction, the battery is completely destroyed, the battery can not be used in the future, because it has been unable to inject new electricity.

Apple used NiCad batteries to retain enough power to use laptops for 1-2 months. Storage of a 12-month NiCad battery is still likely to inject new electricity.

Apple's previously used NiMH (Nihy) battery, like NiCad batteries, still retains enough power to use a laptop for 1-2 months. NiMH (Nihy) batteries, which are stored for 12 months, can still inject new electricity. However, if you have a PowerBook 500 series notebook, you must use the intelligent Battery recondition software to "wake up" a battery that is deeply discharged in storage.

All of Apple's laptops now use liion batteries, which are still able to retain enough power to use the laptop for 1-2 months. Liion batteries, which are stored for 12 months, can still inject new electricity.

Liion Battery After 24 months, the liion battery may not be able to receive new power injections again after December, when the battery can be "discarded battery". When discarding these batteries, be aware of the relevant battery handling and environmental laws in your country (region).

　　Best Set

You can improve and optimize the use of your laptop battery through a variety of system settings:

· The "Energy saver" setting in the system settings, in the "Battery" settings in the "optimization" setting, you can select "Longer battery life", and selected sleep and other settings. "Sleep" settings can be put "to make the computer sleep, when it is inactive for the time" and "to make the monitor surface, when the computer is inactive for" The parameter set lower, and select "If possible, make the hard drive into sleep" option. In options, you can select two options for the brightness of the Si cho monitor with this power supply and the brightness of the monitor to automatically lower the display before the monitor goes to sleep.

· Display brightness: In order to further increase the battery use time, should be lowered the brightness of the display. Now on the market, Macintosh laptops can press the F1 (darker) and F2 (brighter) buttons to adjust at any time. One case is on the plane: if the aircraft has lights out, you can choose to lower the brightness of your display when you watch the DVD.

· Airport Wireless network: Even if you do not use airport to connect to a network that is in use, or even if you do not use it to find a wireless network to use, an open airport wireless network system consumes electricity. You can choose to close it.

· Bluetooth wireless and other network interfaces: You can also turn off Bluetooth and other network interfaces, such as Ethernet, that you don't need to use. They can all be energy-intensive.

· Audio: When you do not need to listen to music or other video, audio content, you can press F3 to set the computer to mute state.

· Applications and accessories: Close applications that do not need to be used and disconnect devices that are not in use. If you have a CD in your computer, you can take it out when you don't use it.

· Use caution: Avoid programs that consume large amounts of software, such as some Microsoft applications. You can write text using a TextEdit program such as the system itself. In addition, you can choose to close unused windows.
