Thanks for the additional support Rustys
You mention uninstalling/re-installing the Microsoft ACPI items in Device Manager, have you tried removing the battery when the computer has booted up, uninstall the drivers, restart the notebook, reinstall the drivers and then reinsert the battery while the computer is booted into Windows.So far I've tried uninstalling/re-installing the Microsoft ACPI items under device manager AND buying a new battery... but no luck.
Never thought to ask what % was showing, if you disconnect the AC adapter and use the notebook does the % reading drop at all.Bizarrely however, I took my laptop to work today and have plugged it in multiple times and I've just checked my battery and I'm at 78% now - I've been stuck on 48% since I started this thread.
A faulty charging circuit on the notebook and/or the DC jack port, if there is a pin in the centre of the DC jack port on the notebook check that it is not bent or loose.What explanation could there be for the sporadic charging?
