The length of laptop running time may vary a lot, It depends on the running applications and the external devices connected to your laptop. Battery operating time (the time the battery can hold a charge) will decrease over time. When you travel with your laptop, you would want longer battery life. Here are some basic tips may help you.
1. Dim laptop screen - Adjust your screen brightness(Most laptops come with the ability to dim your laptop screen); As the screen will take 30% also power of the battery, Try turning down the display brightness to the lowest level you can bear(don't no hurt your eyes).
2. Cut down on unnecessary programs - Cut unnecessary auto running programs when boot up ,cut background programs like Itunes, Desktop Search, etc., Shut down everything that isn’t crucial when you’re on battery. You'd better save the basic firewall software when you are online.
3. Unplug unnecessary devices - USB devices (like mouse, keyboard, other widget chargers), PC cards, DVD drivers, Bluetooth and WiFi will extract your laptop battery power a lot. Remove all of this if applicable. Also check for other built-in components that you could disable to conserve more battery power.
4. Use power saving. Remember that standby mode still uses battery power a lot when you left , But use hibernate instead will save more if your laptop supports this function .
I do think the price of products in this store is much fairer than any store's products. The Compaq Presario CQ40 battery(12 cells 8800mAh) only cost me 65.77 dollars; and it's the lowest price that I have ever seen of the same product. It's really an amazing price!------------------Ryder PHILLIPS
The capacity of this Compaq Presario CQ40 Battery(8800mAh 12 cells) is really very high. When I put it into use, it works as well as described on the website. It can lasts for almost 3 hours when it in standby state. That's enough for me.------------------Alvin BEARD
