Once again I'm writing a post about my frustrations with Vista and power options. On reflection it may seem obvious but when adjusting settings that MAY affect power, always adjust them in the state you want them applied to.

An example should make this clearer. Having read elsewhere on the web that Lenovo has created a bespoke power plan for it's notebooks that disables Aero Glass I decided to do likewise. I'd felt that Vista used more power than XP on the same notebook and constant use of 3D graphics seemed like an obvious culprit.

The snag is that I disabled Aero Glass when I was working with the power cord connected. When I turned the notebook back on this morning on the train, Aero Glass was back again in all its limited finery. When I got into the office and turned the notebook on again, this time with the power connected, Aero had gone again.

My irratation is that there is nothing to suggest that Aero Glass settings have any relation to power settings. I think there may be many puzzled users on support lines wondering why settings are changing back and forth without realising that it is because of whether the notebook is connected to the mains or not
