I downloaded the Power Manager Driver and the Power Management Utility from the beta website. I was quite confused by the nomenclature on the beta driver website used to describe these two packages. After downloading both of them and having a look inside the zipped files, I have come to the following conclusion: The item on the beta driver website entitled 'Power Management Driver' (6hku06ww.zip, about 0.99 megabytes) seems to be the actual driver. This corresponds with the item called 'Power Management Driver' at the normal (non-beta) Thinkpad. The item on the beta driver website entitled 'Power Manager' (6ju401us.zip, about 12.6 megabytes) seems to be the software that provides the interface for using the power management functions. This corresponds with the item called 'Power Manager' at the normal (non-beta) Thinkpad.

However, in the body text of the beta driver website, this second package (the big package) is also referred to as a driver, which can be a bit confusing. I think it might be a good idea if one of the Lenovo team members corrected this confusing nomenclature.

I think that the correct protocol is to install the smaller package (the driver) first, then to install the power manager (which depends on the driver being there first in order to function) second - but I am not 100% sure about this, perhaps someone with more knowledge than I could confirm this. The smaller of the two packages (the actual driver) is version 1.53 - at least, today that is what it is - and the current Vista version at the non-beta DDFM is 1.52. So far, I have only installed the smaller of the two packages (the driver), because I don't like to install too many new things at once - it makes troubleshooting difficult if problems arise later on. I'll use my computer for half a day of work and make sure it is working OK before I continue and install the actual Power Manager (the bigger of the two packages).

It goes a long way toward helping me forget that the battery in the back of the computer is (like every other computer manufacturers' battery) probably going to wind up in a toxic waste dump when it reaches the end of its life.

Anyway - after admiring that elegant looking dark green battery icon for a while, I clicked on it, and all the functions that showed up in its menu worked, so, I guess we can call this particular driver a success, at least on the W500s anyway. I've noticed a small problem with the new Power Manager (the 3.0 version). When I installed this new program a few days ago, I was connected to AC power, and I chose the 'Maximum Performance' power plan. However, I was quite surprised to find out that even after choosing 'Maximum Performance', the 'Advanced Settings' for the wireless adapter were set to 'maximum power savings' when running on AC power, rather than being set to 'maximum performance'. I don't know if this was caused by an error in the default setup for 'Maximum Performance' that came with the Power Manager, or if it was an artifact that carried over from a previous user setting of the power plan resident on my machine. Either way, though, I think that all of these configuration choices are starting to get out of control, and it might make sense for Lenovo to be a bit more aggressive in setting up the defaults for the Power Manager such that if the doggone computer is plugged into AC power, the Power Manager automatically switches over to 'Maximum Performance' for everything that it controls. Realistically, who the heck is concerned about saving power when the computer is plugged into AC?

If the default power plans were set up so that if the computer is running on AC power, everything switched over to the highest possible performance level - by this I mean the wireless adapter, the CD, the processor, the fan, the screen brightness, the works - I think there would be a lot less complaints about system performance, and a lot more user happiness. In other words, set the darn Power Manager defaults up so that it runs the computer at maximum performance anytime it is plugged into AC, regardless of what power plan has been selected.
