A very important criteria when choosing a laptop is how long it runs on battery power without having to connect to electricity. Laptop battery life will vary from one system to others. There are many features that can affect: Power CPU, RAM capacity, quality of the battery, etc. But do not forget that the duration of the battery also depends on the people who work with it. This is the way how to make your laptop run longer without recharging:
If you still want more, you can remove most of the visual effects: In the System Properties – Advanced – Performance and then set the best performance, it will not only save power, but also increase system performance.
Always turn off unnecessary devices if you’re not using them: USB, Bluetooth, Wi fi, IrDA. Related with CD-ROM is better to copy the entire data cd rom to the HDD and only access the data from it.
Turn off unnecessary processes, the processor can find better uses than to display on your desktop calendar and find out the same workload. If you will be taking a break use the sleep mode on laptops. If you go for a long time – turn off your laptop.
Currently there is often a battery memory effect NiMh eg. A brief description of a memory effect itself as follows : if every time you charge the battery only by 60%, then one day the battery will forget that there is still room for 40% of unfilled. The battery will assume 60% is 100%.
To recharge NIMH do not have to wait really – completely discharged, but the consequences will be felt quickly exhausted. But this will be temporary, when the battery runs out, recharge the battery and its ability will back to normal.
