Hi - a very odd situation here.....
The laptop does not seem to recognise the correct battery status. For example, battery power icon can state: 100% charged yet when adapter cord is removed in order to run on the battery there is almost instant shutdown. On the other hand, having (presumably) charged the battery, if the adapter cord is removed whilst booting to Windows, it runs quite happily on the battery despite the power icon saying "0% remaining".
And on the other hand again, it won't cold boot without the adapter cord in. I have tried uninstalling the Microsoft ACPI-compliant Control Method Battery but no luck with that....
Maybe the wrong board to post in but could find no appropriate option for this laptop
