Most importantly, do not update any driver if the existing one is working okay.
Driver updates are not compulsory!
If you need a newer driver because it fixes a specific problem you're having, or it offers new features you need, download it only from your laptop maker's website. For Lenovo UK, that's here: http://support.lenovo.com/en_GB/
We do not recommend the use of driver-finding software as you've no idea where the drivers are coming from or if they are malware-free.
