Dell Inspiron N4010 Troubleshooting

Dell's entry level laptop with a 14" screen.

Slow Computer Performance

Your computer takes an unusual amount of time to do offline activities

The Computer is in Battery Saver Mode

If your computer is set to a battery-saving mode, it may be the throttling the cpu which would lead to slower completion of simple tasks. Power modes can be accessed by clicking on the battery indicator in the lower right of the screen or in Control Panel.

The Laptop is Using all Available Resources

Right click the taskbar and click Start Task Manager then click the performance tab. You will see some graphs. If CPU usage is over 20% with no applications open and ram usage is over 50% with no applications open then you may need to perform a system restore or upgrade your ram or change your CPU

To perform a system restore open the start menu and search for System Restore then follow the steps in the wizard. NOTE: This will effectively take your computer back in time before these issues arise and will cause you to loose files created after the time indicated on the restore point. Back-up any data you don’t want lost to a separate drive.

The Fan is not Circulating Air Properly

If the fan isn't working, or not working well, the CPU will heat up and slow performance to manage its heat. This is called thermal throttling and can be solved by cleaning or replacing your fan. Follow the fan replacement guide for the Dell Inspiron N4010

Power modes can be accessed by clicking on the battery indicator in the lower right of the screen or in Control Panel.
