1. Don’t get too attached
Apple’s customer care says you should do this to “keep the electrons in it moving occasionally.” Wired has a HP HSTNN-CA27 better explanation of whyhere. But the bottom line is, doing this can help prolong your battery life by as much as four times.(1.Keep it between 40 and 80 percent. 2.You should also fully charge and discharge your computer’s HP HSTNN-CA27 battery at least once a month)
2. Stay cool
That’s not to say you should be completely paranoid about keeping it on flat, cool surfaces all the time. But maybe consider moving it to a desk before you fall asleep or head to work(between 50 and 95 degrees Fahrenheit).
3. Update, update, update
You may fear change, but change can extend your HP HSTNN-CA27 battery life. So make sure you have the latest software installed on your computer.
4. Don’t just leave it there.
You should store it with a 50 percent charge in a consistently cool area. Storing the computer with a fully discharged battery might ruin the HP HSTNN-CA27 battery forever. And storing it with an absolutely full charge might cut the battery’s lifespan short.
5. New HP HSTNN-CA27 Battery Pack must be fully charged before use.If you don't use your laptop for a period of time,you must fully discharge then recharge the HP HSTNN-CA27 battery.
6. Always use a Acer laptop on a hard surface. Don’t put it on your lap (despite its name) or on thermal insulating materials such as cushions. If you like to work in bed with your laptop, I recommend using a laptop table. I have this one, and I am quite content with it.
7. Try to avoid charging the battery while you are working with the laptop. Charging the HP HSTNN-CA27 batteries increases your laptop’s temperature. The problem is that the CPU, the graphics card and the hard disk also heat up your laptop, which adds to the temperature increase experienced when charging the HP HSTNN-CA27 battery. Many vendors deliver their laptops with software that allows you to disable charging. You also can remove the HP HSTNN-CA27 battery while you are working on AC current.
8. Make sure the laptop’s ventilation can always work properly. Don’t place objects before the ventilation systems opening. Don’t run or charge the laptop while it is in its case.
9. Don’t leave the laptop in the car or under the sun in summer. Use a bike. It keeps your HP HSTNN-CA27 laptop battery cool and your own battery healthy. And too much sun exposure causes only skin cancer anyway.
10.Use the elucidation of the portable laptop battery
New battery pack needs to be fully charged and discharged (cycled) for one week before it can arrive the full capacity.
Rechargeable battery undergo self-discharging when left unused and Always store a battery pack in a half fully charged staged for storage.
Set screen saver blank to 1 to 2 minutes of your notebook, Remove unused PC Cards or USB devices from your notebook.
Don't watch DVD or pl.
