Windows The past few weeks or so, there's been a lot of interest in a supposed battery status report bug in Windows 7. After installing Windows 7, some users reported seeing "consider replacing your battery"-warnings in systems that appeared to be operating just fine on Windows XP or Vista. After extensive research, Steven Sinofsky has now explained on the Engineering 7 blog that the fault is not with Windows 7 - it really, really is your battery.

Also, just because a system has ACPI bios doesn't mean you're machine will adjust itself (scale back the CPU and/or FSB when not needed, etc). This, too, typically requires a driver or utility as the os itself doesn't often handle it.

Fair enough... this was one major lacking feature in XP (likely present in W7) - I do recall installing "Intel Speedstep" on several of my laptops in order to reduce CPU performance.
