hi there, i installed the xp drivers for my wireless keyboard and mouse from Trust.com once installed these devices seemed to prevent my windows 7 pc from now going into hibernation. all very well, i thought - but when i decided to stop using the devices now, and uninstalled them the pc still did not want to go into hibernation. Not only this, but my mouse touchpad will not work - this is for my wife's computer, an HP 530 I tried to enable hibernation in the bios but got the following message: "The following items are preventing hibernation on the system. There are one or more legacy drivers installed on the system: i8042prt " I have verified that the programs have been removed, I have also removed the items from the registry... Still I cannot get the computer to hibernate or enable the touchpad? (I have installed the latest synaptics touchpad software too) Please help, many thanks!
