Can my laptop turn off battery charging automatically?

How to use laptop battery? usefull?

• 1. Smaller Is Better Consider an ultraportable or thin-and-light rather than a desktop replacement laptop. Smaller ACER laptop battery displays use less power. Going with a hard drive that runs at 4200rpm uses less power than a hard drive running at 5400rpm. 2. Power Control Use as little power as possible by adjusting laptop settings. Use the Power Options to set to the laptop to go inactive after a set amount of time. Set adjustments so that the display goes off first, then hard the hard drive stay active a bit longer and store the system contents to the RAM. 3. Turn Down the Lights Adjust the display brightness to a lower setting, make sure you can view the screen without squinting. You can also adjust the brightness of the display to suit the conditions you are working in. 4. Watch Your ACER Laptop Battery Use Keep an eye on your ACER laptop battery consumption and know how much power you have remaining. Use the laptop battery power icon on the system tray or you can purchase batteries which have LED gauges on the outside of the battery itself. 5. Charging It Up Whenever you have access to a power source, charge the ACER laptop battery. Before you leave on any trips, fully charge the laptop batteries, especially if you don't know where or when you might have access to any electrical outlets. 6. Get Another Battery Some laptops are capable of running with two batteries. If you cannot run two batteries, check with the manufacturer to see if there are high capacity batteries available. External batteries (ACER aspire 3000 battery)can also be used to extend operating time. 7. Drain the Battery The first time you use your laptop with battery power, allow the Acer laptop battery to completely discharge. Do this at least twice and don't try to charge the laptop battery when it is half discharged. 8. Clean Batteries Keep the battery and its connections clean and free of debris. Clean your ACER laptop battery terminals on a regular basis using a cotton swab with rubbing alcohol on the tip. 9. CMOS Battery Check-Up The backup battery is a CMOS battery which is a secondary laptop battery (such as ACER 2300 Battery) to power the clock and can drain a main ACER laptop battery if it is dead. Check with your User Manual or manufacturers web site for the location of the CMOS battery and where to get a replacement. 10. Turning It Off Don't run programs or devices that you aren't using. Remove PC cards and turn off Wi-Fi software. Using your laptop to watch movies or play games will drain the acer laptop battery quickly as well. Just follow this simple steps, yousave much time to extend your acer laptop battery life and other Laptop Accessories. from www.batteryrealm.com

  >Going with a hard drive that runs at 4200rpm uses less power than a hard drive running at 5400rpm. Uhhh... I don't think any 4200RPM drives exist on the market currently. SSD's however will make a better replacement for any hard drive -- SSD's are fast, have no moving parts and use a lot less power. They're a much newer technology than hard disks are. The downside is that they're a little costlier than HDD's, but $150 dollars will get you a reasonably sized 128 SSD now. http://www.amazon.com/Crucial-2-5-Inch-Solid-State-CT128M4SSD2/dp/B004W2JKZI/ref=sr_1_1?s=electronics&ie=UTF8&qid=1333459592&sr=1-1 Steps 2 - 10 makes sense. I don't agree with number 8 though -- unless you use your laptop in a VERY dusty or in an outdoor environment for long periods of time, you don't usually need to swab your laptop battery terminals with alcohol. There are additional points that I want to make: 1. Charge your laptop whenever you feel like it, and preferably do it often. You do not have to wait until the laptop battery goes flat to recharge. This is a habit that you should practice with Nickel Cadmium batteries, but Lithium-Polymer batteries will actually degrade and die faster if you do this. So DON'T fully discharge your battery everytime you charge -- Li-Po batteries are called "smart batteries" and don't have memory effects like NiCads do. 2. You should calibrate your laptop battery once every 6 months. Your laptop usually has a manual showing you the best way to calibrate it. But, the usual procedure involves charging your laptop to full, then letting it run down until it nearly depletes, then charge it back up again. 3. If you are planning to sit down with the laptop near a power source for long periods of time, you might want to give your battery a vacation by removing it from the laptop. That way, you won't wear down the battery when you don't actually need it, and preserve it's life a bit longer. Laptop batteries have limited lifespans -- after several hundred discharges you'll start to notice that it's capacity will begin to decrease.
