How do I calibrate the battery for my Presario 2100?

Question

I'm having battery problems.

Answer 1

Once the battery for your Presario 2100 builds a memory, there is very little you can do to repair it. New, the batteries hold almost two hours of use. However, the battery to my Presario 2100 will only hold about 40 minutes of a charge.

The drawback to the Presario 2100 (and a lot of the older laptops and a good number of the new laptops) is that there is not an effective system of power management. This is seen more often with cell phones, where there is a "smart chip" that manages the charging of the battery without creating a "memory" to the battery.

I suggest that you replace the battery. I have found a few laptop batteries online for the Presario 2100. If you search, you may find a better deal. However, I will warn you that computer parts are produced for only a few years, according to market demand. Once they stop producing the parts, the price will go up as supplies decrease and demand increases.

Good luck!

Answer 2

when you press the power button on your laptop, try pressing F1 or F2 to enter bios setup. try to look for an option which says refresh battery. choose this option. this will drain the battery slowly and completely.when the battery is completely drained, charge the unit while turned off. pay close attention to te charging time and the battery indicator. as soon as it is full, remove the charger from the laptop and try running it on batteries. if this does not appear to be available, just drain the battery manually by booting up and letting it sit until the battery completely drains then charge it while turned off and it will be configured back to its factory settings provided that the battery is still in good condition.
