I have a HP DV7 notebook which came with Windows7 Home and everything worked really well on it. I then installed my original copy of Win7 Enterprise (which I bought thru work) and found that when I unplug the notebook from the power brick, it starts to slow down to the point where it becomes unsuable.
I've checked the CPU speed and that does not change, the memory & HDD was tested by an HP technician and nothing was found wrong. When I plug the power back in, the notebook starts running as quick as it should so really I can only use it while it is plugged into power which is not the ideal situation with any notebook.
If I run it in Safe Mode it works great with or without power so it must be something to do with a Windows driver. The HP technician was dumb founded and suggested that I reload the original Win7 Home and leave it that way. I did not want this to be the resolution so I'm asking you guys if you can help me.
I re-installed Win7 Enterprise (a few times!) and as soon as I finished installing Win7, it slows down when power is unplugged. I then installed all the drivers using the HP Support Assistant and SP1 and it still does the same thing. It has me baffled.
What can I do next to fix this?
Regards
Julian
