Hi to all,

  I am looking for suggestions on a very battery efficient laptop or notebook computer with a regular-sized screen and keyboard. In other words; a laptop or notebook that seems to last forever with its own internal battery...

 

  Also; I was wondering if anyone ever powers their own laptop or notebook computer with an external battery of some kind for extended operating away from an a/c outlet, and if so, how do you do this? Although I have never personally seen anyone ever do this, I can't help but think that someone hasn't at least tried it, and if so, I am wondering how to do it...

 

Also; are there ways to extend the battery life of my old laptop computer or should I just purchase the newest battery technology for it?

 

Thank you

Punchy71

The 12-inch ultraportable Lenovo ThinkPad X230 with both the 9-cell battery and sheet-battery options will run for 20+ hours.

Whichever laptop you look at, keep in mind that the battery life will not be 100% accurate to what the specs say. The manufacture always says the battery life will last longer than what it really does. For example, if a website says the battery life is 5 hours, in reality you may only get 3 hours or less. But, with the way companies are making new products like the one SpywareDoc mentioned, there are ones that can definately last pretty much all day. But dont go by the exact number of hours that the specs say, always assume it will be less.

I should add that not every single model will have less battery life than what it says lol, but many do. I worked retail for 5 years and many laptop batteries last a lot less than what the box says.

Depends on what you are doing with it, they test the battery life running a couple basic programs, if you are constantly using it for gaming it will last a lot less time than for surfing the web or writing.

 

Either way sometimes you can find either second batteries, or extended batteries for a decent price (I had an old HP that the battery died in, bought a new extended battery for about 100 and saw a 50% increase in battery life.

Some tips to extend battery life.

1. On older Non LED models especially, The dimmer the screen the longer the battery life.

2. Switch to a SSD drive instead of regular drive. No motor to keep spinning in use, Powering down the motor can introduce delays.

3. Use the Longer life battery, More cells = More capacity = Longer run time.

4. Do not use USB devices as they consume power, Especially drives.

5. Do not use the DVD drive.

6. Do not use CPU intensive applications when running on battery. They cause the CPU to use more power and the CPU cooling fan to use more power getting rid of the heat.

7. Configure unused hardware to turn off when not needed. Wireless for example.

 

Some older Dells for example you could pull the Optical drive easily and install the second battery pack that they sold for it.

 

Good Luck

Roger
