How do I extend the life of my laptop battery ?
- 1 . New hp HSTNN-DB90 Laptop 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-DB90 Laptop battery.
- 2 . Always use a hp 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.
- 3 . Try to avoid charging the battery while you are working with the laptop. Charging the hp HSTNN-DB90 Laptop battery 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-DB90 Laptop battery. Many vendors deliver their laptops with software that allows you to disable charging. You also can remove the hp HSTNN-DB90 Laptop battery while you are working on AC current.
- 4 . 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.
- 5 . Don’t leave the laptop in the car or under the sun in summer. Use a bike. It keeps your hp HSTNN-DB90 Laptop battery cool and your own battery healthy. And too much sun exposure causes only skin cancer anyway.
