== Slow Computer Performance ==
 
''Your computer takes an unusual amount of time to do offline activities''
 
=== Change Power 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.
 
=== Check RAM Usage/CPU Use ===
 
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.
 
=== Clean/Replace Fan ===
 
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''
 
=== Change Power 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.
 
=== Replace Battery ===
 
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.
 
== Computer will not turn on unless plugged in ==
 
''See above''
 
=== Check battery contacts ===
 
Remove the battery from the underside of the laptop and check to see if any of the contacts are damaged or dirty on either the laptop itself and the battery
 
=== Replace Battery ===
 
Replace the battery by following the battery replacement guide. Make sure you use Dell batteries (found here) //link to dell battery available to purchase
 
== Computer will not charge ==
 
=== Change wall outlet the power brick is plugged into ===
 
=== Replace Power Brick and/or cord ===
 
If the power brick is not getting warm at all when plugged in, the 3 pronged cord going from the wall to brick might be the issue.
 
=== Replace Motherboard ===
 
Follow the motherboard replacement guide
 
== Certain keys unresponsive ==
 
=== Replace keyboard ===
 
Follow the keyboard replacement guide
 
== Touchpad gestures not working ==
 
Update device drivers through dell's website [Link] or clean touchpad with a dry microfiber cloth
 
== Speakers not working ==
 
''Sound should be playing through the speakers but is not''
 
=== Turn up sound ===
 
In the taskbar click on the speaker icon and drag the slider upwards. You should hear a chime.
 
=== Update drivers ===
 
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)
 
=== Replace speakers ===
 
If one speaker works then the other is almost certainly broken and needs to be replaced. Follow the speaker replacement guide.
 
== Screen issues ==
 
'' 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. ''
 
=== Constant BSoD (Blue Screen of Death) ===
 
For this, first check Error Code Guide on Microsoft’s website.This will tell you nature of the problem. Other fixes include restoring the system, replacing RAM, or even replacing the CPU.
 
=== Screen wont turn on ===
 
To resolve, first try external display on both VGA and HDMI. If this works, this means the actual screen could be the problem. Try either reinstalling video drivers and/or re-configuring screen settings. If this still doesn’t work, consider replacing the screen. However, if the screen does not work but the power lights on the laptop body are on, consider replacing the laptop’s battery or even replacing the CPU.
 
If the screen flashes on and the computer begins to make a "beeping" sound use the following guide to determine the issue: https://www.dell.com/support/article/us/en/04/sln293445/understanding-beep-codes-on-a-dell-desktop-pc?lang=en#Intro //this will be hyperlinked with user friendly text like "[Link]"
 
== File Issues ==
 
''Files are either changing names, locations, or disappearing.''
 
=== Hard drive replacement ===
 
Follow our hard drive replacement guide. Please note you must back up any files on the drive, including recording any software keys, especially for Windows. You must also have some sort of installation media created for Windows as you will need to reinstall it after replacing the drive.
