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
Short Battery Life
Your computer dies in less time than the manufacturer indicates
Computer Is in High Performance Mode
Changing your power mode to a high performance setting will use more power than a battery saving mode. If performance is not required then changing the power mode is the easiest way to get better battery life. Power modes can be accessed by clicking on the battery indicator in the lower right of the screen or in Control Panel.
The Battery is Old and Needs to be Replaced
The battery that is dying faster than indicated by manufacturer might be faulty. Batteries also don’t hold capacity as they age. Replace the battery (*dell link*) by following the battery replacement guide.

The Wire Coming from the Plug to the Power Brick is Faulty
Replace the cord with any 3-pronged cord with the appropriate connections. Simply pull the thicker cord out of the power brick and insert a new cord into the slot. Make sure the wire itself can handle the Voltage and Amperage supplied by your pug.

If this doesn’t work, plug in external speakers/headphones and if that makes sound your speakers are bad, if that doesn’t work you need to update drivers (only if both speakers and headphones are not working)
Speakers are Broken
If one speaker works then the other is almost certainly broken and needs to be replaced. Follow the speaker replacement guide.
Many common issues reported are associated to its screen. If your screen is in constant BSoD (Blue Screen of Death) or it will not turn on, consider these helpful steps.
