Cannot calibrate battery after reverting to Windows XP from Windows Vista

I have an HP Compaq nx7300 laptop, which came with Win XP.

I recently decided to try out Vista on it, but eventually changed my mind and reverted to windows XP.

The prob I'm having is that since i switched back, the battery doesnt seem to want to calibrate. Tried to calibrate it according to HP's instructions as described in the link below but to no avail.

The battery meter just marks 100% or 0%. This only started happening after i reformatted my notebook and re-installed XP.

Laptop is around 1 1/2 yrs old and I dont think the battery is dead yet as if i restart the pc it will still work for considerable time after windows says battery is 0% and hibernates.

Any advice as to how i could calibrate it?

After installing XP you have to install the motherboard drivers, chips driver, then recalibrate.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Tried Both, unfortunately no luck.

Am considering trying the BIOS update as its not the latest. Are there any repercussions to that if the bios upgrade goes wrong?

I understand that it was working before Vista installation, it means that it should work with the current BIOS, anyhow before updating try to reset the BIOS, there are an option in BIOS setup to do so, think it should work after resetting.
