Hi.

I have an HP ellitebook 8530P. I am using a aftermarket battery as the OEM one (which lasted me over 4 years) died. The battery is kept in the laptop 24/7, with the machine connected to the AC adapter.

All of a sudden. the battery now only lasts about five minutes. Windows's percentage counter runs down super fast. Then the machine shuts down. At boot, the BIOS also warns me that my battery has very low capacity.

However. After windows shuts down, if I restart the computer, windows boots, and tells me I have 7% remaining. However, the machine will run for another 2 hours just fine, at "7%".

I have tried running the battery down and then fully charging it. I have also tried the method of removing the battery from device manager. Nothing has helped.

Is there any other way to calibrate it or fix this?

Thanks

Matt

Could be, but it has had a great run time for the last 4 months.

I'm just wondering if there is another way to calibrate it.
