- Restart the computer into Safe Mode with Networking .
- Starting the computer in Safe Mode with Networking will ensure that all unnecessary background applications are closed, and will also clear the print queue.
- Safe Mode with Networking will also allow testing of Internet connection capability.
- To ensure applications that load when the computer starts are not causing the computer to slow down, remove unused or infrequently used applications from startup.
- Configure power options for optimal performance.
- Configure the turn off hard disk time to the lowest setting.
- Some computer models include the VAIO Power Management application which can be configured to increase performance. Check the user guide for availability and usage.
- Configuring power options for increased performance usually decreases battery life.
