LapTop Battery Recalibrate

[JBH1876]

Was wanting to learn why a new laptop battery has to be calibrated before it will charge fully... Gateway Laptop....... Thanks

How about longer battery life for starters.

I like this idea.
However, you can ensure the most accurate readings of available energy by letting your notebook run unplugged until the battery is depleted once each month. This will help your battery remain calibrated and ensure that its internal chip has a trustworthy estimate of the remaining battery power.

I've had this laptop running in the calibrate mode for 5 hours, and its been at 18% progress for 3 hours........ Hasn't went any further.......... ??

What I do, may not be the best way, but. .

Set the cpu to the high power scheme.
Did a AV scan, defrag , which brought her down to about 20%, let her set until it shutdown.

Without doing that, the power scheme and battey size, will cause it to be a whole lot longer to run down.

Hope this helps out.

Did some more searching and found this:

And that pretty much follows what HP says.

And this maybe more than we care to learn.

I noticed a big difference. Shuts down at 4% now instead of 18%.

I found this suggestion this morning: Fully Charge Battery, Go to Start > Shut down, restart... then ok.... Press F8 choose "Sate Mode with command prompt", unplug a/c adapter,, leave laptop on until it shuts down by itself to fully discharge..... repeat this step 4 to 5 times for the battery to recognize its full capacity...........
