I see that you may have one of those machines where folk installed "Windows 7." Today it's still that same old story that we go driver hunting and more.
Yes, you claim you have the latest drivers but it is no longer funny when folk write they used the "Update Driver" button.
The laptop maker must detail what drivers and apps to use. You and I can't guess this.
I have both Windows Vista and Windows 7 on the same PC. I run a 64 bit version of Windows 7 and both Vista 64 and 32 bit. The problem is that no matter what mouse I choose to use on Windows 7, shortly after using the system for at least an hour I either have pointer problems or battery problems. I use the same mouse on Vista and it can go months without an issue with the batteries going low. I have used othe mice but I am used to using the MS Intellipoint. On both O/S's I have the latest drivers and where the MS system gives you a leaway on usage on the changing of batteries the Win 7 system gives you hardly any recovery time before replacing the second battery. I use mainly photographic and artware programs so The issue is lagely to do with the workspace management in windows. Power seems to be a high wastage on win 7 whereas win Vista just takes its time to boot in. The driver database in both Win 7 and Vista seems to be identical about the only difference I can find is in coordinate checksum amalgamation on a 64 bit datalog. Something needs to be sorted because this is not the ideal selling point for Windows 8. In fact I am even more put off of the newer interface because it seems to be catering for smudgey fingers more than the everyday user whom uses the computer to work for him.
