If "System Restore" does not work on Lenovo notebooks, please try the following steps:
1. Make sure "System Restore" is running.
2. Make sure there is enough space on all drives to run System Restore. If free space falls below 50 MB on a partition monitored by System Restore, System Restore pauses and clears all restore points to free up disk space. System Restore will automatically reactivate when free disk space reaches more than 200MB.
3. You can check the event log for errors related to system restore.
