Laptop Batteries

Ok, my dear husband's two year old laptop no longer has any battery power (about 5 minutes or so before it dies) so we stopped by the local battery specialist and learned some important things about Lithium-ion and Lithium-polymer batteries.

A laptop battery's lifespan is approximately 1,000 charge cycles, or 2-4 years under normal operating conditions.  The battery in question had around 75 cycles and was determined to be dead.

My husband's laptop normally stayed plugged in.. after all, you would think that plugging it in would bypass the battery.. wrong. Instead it was damaging, by overcharging the battery.  

It was recommended that you discharge the battery until you get the warning on the laptop or even better, discharge completely, then plug it in.. charge to full and then disconnect the power.   Run the battery down and recharge it at least once every month, even better, every couple of weeks but optimally.. every day.

Matter of fact, he stated that with a new battery, do this discharge cycle a dozen times or more to "synchronize" the cells. It increases the longevity of the battery.

Some things that will degrade your battery:
  1. HEAT.. heat will dry out the battery so don't leave your laptop in the car in the summer. 
  2. HEAT.. so don't let the battery get hot by leaving it on while on a bed or other soft surface. 
  3. HEAT.. keep the vents on the laptop free from dust by using a keyboard cleaner (canned air) on the vents.
  4. Leaving the battery constantly charged will greatly reduce the life of the battery just like my dh thought  was the right thing to do.
  5. Keep your system running optimally by defragging your system monthly and using system resources wisely.. The better running, the less energy used, prolonging your battery.
Who knew?  The person that will be selling us a replacement battery to the tune of about ♪♫ $90 ♫♪. So who is the smart one?  Well, we are now...

How Do We Prepare Students for a Global Knowledge Economy?

I recently participated in a discussion regarding the direction of our community here in Northwest Georgia. Although many candidates for our county commission would like to see more manufacturing jobs, I truly feel that we are not preparing our students to be part of the 'global economy'. Why are we happy with more retail jobs at minimum wage or warehouse  jobs for $10 per hour?  In our community we can strive to provide a better education geared toward the future. We can also improve our local economy with drawing technology related businesses that are required to have access to highways and won't require more truck routes into our area. We, as a community, aren't preparing our students to strive for better jobs. We, as a community need to move into the 21st century before its too late. Check out this seminar on preparing our students for a global knowledge economy.  I hope you will consider the need to prepare your children for the world with soft skills such as d
