Computer won't turn on ¶ 

When you press the power button and the computer doesn't turn on.

Dead battery ¶ 

One popular reason why your laptop may not turn on is that the battery is dead. When the battery is dead, the laptop has no source of power, and therefore it cannot turn on. To fix this problem, plug your laptop into a working outlet using the AC adapter (charger) that came with your machine. Make sure that the charger is securely plugged into both the laptop and the outlet. Also check that there is no damage to the charger. If the charger is fully plugged in and functional, the charge status indicator will light up in an amber color. This light is located in a line of four lights along the bottom left-hand corner laptop. The charging status indicator is the second light from the right, and is labeled with an electrical symbol. This symbol looks like a circle with a plus and minus sign.

Loose battery ¶ 

If your laptop doesn’t turn on, it may have a loose battery. If this is the cause of you problem, it can be fixed in one of two ways. First, stand the laptop on its side so that the screen looks like it is sideways (the right arrow key is pointing towards the floor). Turn the bottom of the laptop so that it is facing you. Making sure that you have a firm grasp on the machine, firmly pat the area where the battery is located. This area is approximately underneath the mouse. By patting this area, you are attempting to push a loose battery connector back into place. You should pat the machine in this way 4-5 times, covering the whole area under the mouse. Once you have done so, turn the laptop back into upright position and attempt to turn it on with the charger attached. If the previous step does not work, you are going to need to physically remove the battery in order to ensure a proper connection. Instructions on how to remove and evaluate problems with the battery can be found here in our guide for battery removal.

Slow internet ¶ 

The loading time while you are online is slow.

Overloaded network ¶ 

If multiple people are on the same Wi-Fi source then the internet could run slower. You can either wait until there are less people online or politely ask them to get off. However this is not a permanent solution, it is a temporary fix to allow you quicker access online, and different methods should be used so that the same problem doesn't occur in the future.

Modem issues ¶ 

Try unplugging you modem and wait 60 seconds before plugging it back in. The reason we wait this time is because of capacitors. Inside of the modem are tiny components call capacitors, and these capacitors are charged up when the modem is on. Unplugging the modem and waiting 60 seconds gives the capacitors time to discharge.

Bad Network Interface Card ¶ 

If you have an old card then your computer might not be able to keep up with the speed of your WiFi. Go online to speedtest.net and run the test, this site gives you the speed of you upload and download capabilities. If the test shows that you have a slow connection a simple and easy fix is using a Wi-Fi adapter to connect to the internet, and the adapter should speed up you connection. Using the Wi-Fi adapter is easy you can buy them at a local store with a computer department, such as best buy or Target. When you get one follow the instructions that come with it, they will tell you the way to install and connect the adapter.

Long startup time ¶ 

When you turn on or restart the computer, it takes a long time to log in.

Unnecessary startup programs ¶ 

When you turn on your computer there are dozens of essential programs that run to maintain operations. Additionally many programs offer the ability to run during system startup. In order for all these programs to run smoothly, data must be allocated through RAM. When RAM begins to become full you will likely experience slow startup time. In order to reduce startup time you can disable programs through system configuration. On a Windows machine you can reach this setting by typing “msconfig” in the run app. Next, go under the startup tab and uncheck any unnecessary programs. Also, make sure you know what exactly your unchecking as you might disable an essential program.

Upgrading hard drive ¶ 

A solid state drive or SSD is a storage component with no moving parts. It stores information through microchips and is much faster than a traditional hard drive. If you are experience slow startup time one you can boot your operating system from a SSD to experience faster performance. Before installing the SSD make sure to ground yourself whether it be by touching a metal object or by wearing an antistatic wrist band. This is done to prevent any electrical damage to the drive. When installing the SSD place it in the drive bay of your computer tower. Next connect one end of your SATA cable and power connector to the motherboard. FInally connect the remaining end to your SSD.

Computer gets really hot ¶ 

When parts of the computer feel unusually warm.

Computer is being used on inappropriate surfaces ¶ 

The fan within the laptop is located underneath it. If the laptop is being used on a surface such as a blanket, the fan cannot blow out the heat. The laptop should be used on a solid surface such as a desk so that the fans have room to circulate the heat. If that still does not work there are cooling stands that can be placed underneath the laptop that have additional fans to keep the laptop running at a cooler temperature.

High data use ¶ 

A possible source of heat can be the laptop working harder than usual by the processes being used. If the CPU is using a lot of data the laptop will generate more heat. A possible solution is to go to the Windows Task Manager to see what processes are using up a lot of data. You can use Autoruns to see the startup processes and reduce them form there. If you stagger the startup processes, it can be less intensive on the processor. You can also install Process Explorer to see the files that the processes have open and how much CPU it is using. This could help you decide what is necessary and what is not.

Dying battery ¶ 

If watching where the laptop is used and cleaning the dust out are not a solution to the problem, the battery may be the source of the extra heat. Many people tend to leave the battery charging even when the battery is fully charged. This will lead to a shorter life of the battery. If your battery is dying quickly it could be generating heat which could be the source of the heat problem. Batteries are sold online or in stores and can be found easily with the model of the computer or battery.

Dusty computer ¶ 

A common reason for overheating is the buildup of dust within laptop. It is an easy fix and highly recommended to try first when trying to solve an overheating problem. First remove the cover on the bottom of the laptop to access the internal components. Then blow out the fans and other areas that seem to have dust buildup with a can of compressed air.

Slow response time ¶ 

The time the computer takes to do what you tell it to do is longer than usual.

Presence of a virus ¶ 

A virus is a piece of data that is capable of copying itself and is often responsible for corrupting and destroying computer systems. If you are experiencing slow response time your computer may be infected with a virus. One of the fastest ways to detect a virus is by using scanning software such as Microsoft Safety Scanner. If a virus is detected there are several rid your computer of the infection. The most practical method would likely be to clean your system with. Through a system restore, you can track back to a date before the virus infected your computer. Although this may destroy the virus, some viruses are able to store copies of itself in an antivirus software. Windows Defender can perform this however, it is advised to look into other software as well. Another method would be to perform a System Restoration. This process, facilitated by Windows, allows you to restore your operating system to a given date. It is advised to perform a virus scan after restoration.

Low Ram ¶ 

RAM(Random Access Memory) is a hardware device that allows information to be retrieved or stored on a computer. RAM is volatile and temporarily stores data to facilitate multitasking and program speed. If running programs often become unresponsive or slow you may have an issue with your RAM. One way to solve this is by freeing up space on your computer by closing programs that may be taking up large amounts of memory. This can be done through the Windows Task Manager. Another option to consider is upgrading your RAM. By upgrading your RAM there will be more space allocated to your programs which should enhance program performance and multitasking speed.
