iPAQ Battery Driver 210 Error

Back on the 30th of May HP claims to have released a driver update that adds support for an extended battery, and includes power management improvements to increase battery life between charges. This update was not adequately tested and contained an error in the registry key resulting in a new registry value being created called Builtln where In was spelled ln that is with a lower case "L". HP has very quietly released an updated driver, if you have not downloaded the driver within the last 24 hours please uninstall the existing driver and download the *new* sp39391.exe
