Conserving Laptop Battery Power is a necessity when you’re using a laptop without a power source. If you have an on-off switch for your WiFi on your laptop, get in the habit of turning it off when you do not need to be online, or if you are in a location without internet access. Your computer is always searching for connections, and it will conserve battery power if your computer is not actively searching.
Disconnect any USB devices that you are not using as these will drain your battery over time. (And, using a USB Flash drive on a laptop with a low battery can actually corrupt the USB flash drive making it unusable!)
Try setting your LCD display to a dimmer setting; the brighter the display, the more battery power it drains and it is a laptop’s biggest power drain. Getting low on power and need to squeeze a little more time out of your charge? Dim your screen even more and you will be surprised how much extra time can stay powered up.
Good ventilation keeps the fan from powering on as much, which in turn conserves battery power. Setting your laptop on a desk vs your lap will actually give your battery more life.
NEVER put your laptop in a laptop bag unless it is completely shut down! There is no circulation at all so it is not even safe to leave it in hibernate or sleep mode.
If your laptop has been in a cold place, like in your car in the winter, wait for it to get to room temperature before you boot up so that condensation does not form inside; it could damage delicate components.
Laptops are constantly being moved around – things like setting it down on a table, transferring to your lap, putting it in a case, etc. This puts a lot more wear and tear on them vs a PC, so be sure EVERYTHING is always backed up. Don’t take chances on losing everything.
There is a lot of controversy on whether you really need to shut down a PC; after all, refrigerators and other appliances run non-stop without being turned off. But, when it comes to laptops, always shut down completely when you are not going to be using it for an extended time.
Check air vents for dust or particles and keep it clean~
While it is nice to keep your laptop in your lap, using it on a hard surface is really the best way to extend the life of your laptop, and helps to control overheating or over use of the internal fan.
Never reposition your laptop from one spot to the next, or from your lap to a table, without unplugging USB flash drives; leaving them in can bend them and ruin not only the flash drive, but the USB port on the laptop as well.
Use a strong password on your laptop; theft is more of a concern with portable devices. If you travel a lot, you should also password protect your BIOS settings; the manufacturer of your computer will have instructions for this. Find out of your BIOS password also protects your hard drive… otherwise a thief could simply remove the hard drive from your laptop and install secondary drive on another machine, or on a similar laptop, and access it.
First and foremost is the defrag. The hard drive usually if made to work fast will reduce the battery consumption also.
