Experimenting with the DPC Latency checker, these were the results with my laptop on
Windows 7. All these green bars are
HALF the height compared to
Vista. The wireless network & ACPI used to cause regular yellow bars in Vista;

With
everything switched on, nothing disabled. The wireless network causes a spike every ten seconds, but there are random peaks & yellows from the ACPI
With only the ACPI-Complient Control Battery Method disabled. Peaks are every ten seconds from the Wireless network, means I dont really need to disable the Wireless network.
With only the Wireless & ACPI disabled.From these results I
only need to disable the
ACPI and nothing else :-)
P.S. HP G70 laptop bought in February this year, Dual Core P7450 2.13 GHz processor, 3gigs RAM, 320gb hd, nVidia GeForce 9200M GE graphics card.
Hope this helps people considering taking the plunge. This was
NOT a fresh install, but, the upgrade from Vista 32 bit to W7 32 bit
