ProBook 6460b...when PC is plugged in, battery at times drops from 100% to 95%

[Peter74]

Periodically the above happens.

I usually unplug the charger, let the battery run down more, plug in the charger and then battery charges returns to 100%.

Should this be a concern for me?

Hello Peter74,

This occasionally happens to me so I don't think you should be too worried. 

You can use HP Support Assistant's Battery calibration or try some guide like this: http://www.tomsguide.com/faq/id-2342991/calibrate-battery-windows-laptops.html

Here is also HP's official document on laptop battery calibration: https://support.hp.com/ph-en/document/c04700771

If the laptop is nearing its 2 year lifetime, this can be considered normal.

Hope this helps,

Eddy

Thank you so much Eddy,

Checked out both of the links and they look like big productions of time.

You mentioned that Laptop is nearing its 2 year lifetime...I hope and expect it will last for many years.

In either case you indicated, "This occasionally happens to me so I don't think you should be too worried."

Problem solved...live with it and do not be concerned.

Appreciate your wise guidance.

All the best.

Peter
