Hi! I recently repaired my SL510 Lenovo Think Pad laptop, using a restore disk set to do so. I have Windows 7. Things are going well, although there are some problems I'm working on trying to fix after the restore. One problem that I also had before the restore, is that my restore to earlier time function is not working. I try to turn it on by going to the Protection tab in the System folder in the Control Panel. And before doing anything - I notice that all of the 3 protection options are turned off. When I click on the C folder and then on the Configure button and select the top option - it does nothing. I am able to select the middle option. And to move the slider. But when I hit the Apply button it refuses, saying it is unable to apply the changes I am asking for. What do you suggest that I do about this? Thanks in advance, for any efforts in helping me to solve the problem!
