Laptop Will Not Turn On

The laptop's will not turn on or respond when the power button is pressed.

Faulty Power Adapter

Check if the power adapter is properly plugged into the computer and into the power outlet. Check if the light on the power adapter is on when plugged into the wall. If the light is not on you may have a faulty power adapter.

Bad Battery Connection/Bad Battery

After confirming the power adapter is not the issue, plug the computer into the power adapter to charge. If the computer does not charge then the battery is likely bad. Check if the battery is properly connected to the computer by removing and reinstalling it. You can use our guide here to replace the battery. If this fails to solve the issue, remove and replace with a new battery. If the issue is resolved then the previous battery is faulty. If issue persists then the issue resides somewhere else in the conduction path in the computer. Solving such issues is beyond this troubleshooting guide.

Cannot Access Files

Files will not load properly on computer. Computer occasionally "blue screens" or will not properly start up.

Faulty Hard Drive

Listen for are any clicking noises or other unusual sounds coming from the hard drive when the computer is on. It is normal for the hard drive to make "whiring" or electronic motor noises, but any clicking or impact sounds within the hard drive indicate that it is nearing complete failure and should be replaced immediately. To access and remove he hard drive, follow our hard drive replacement guide.

Poor Hard Drive Connection

Your hard drive may not be properly connected. Turn off the computer and remove bottom panel. Remove hard drive and reinstall it. Turn computer back on. If the issue persists then the hard drive may need to be replaced. To replace the hardiness, follow our hard drive replacement guide.

Programs Run Slowly or Not At All

The computer cannot perform basic functions or will freeze up when attempting them

Too Little or Damaged RAM

The RAM may need to be replaced or reconnected. Shut off the computer and open up the back panel. Disconnect and reconnect the RAM sticks and power on the computer. If issue persists the RAM will need to be replaced. You can see how to access the RAM using our guide

Too Many Tasks Running

Your computer may be running too many programs, causing it to slow down. Click on the "Start" button and search "Task Manager." Check all running programs and clear those that are unnecessary. Additionally, run a web search of the names of any tasks that are not familiar. If you come accross a task commonly known to be malicious, install a malware scanning application such as Malwarebytes and follow its directions for scanning for malware. Malicious programs can often reduce the performance of your computer by using large amounts of RAM and CPU power. If problem persists new RAM may need to be installed.

Computer Overheating

The computer will overheat when in use.

Clogged or Broken Fan

If you do not hear the fan when you are using the laptop for a resource intensive task, such as watching a video, or working with large files, the fan is most likely not working and broken. The laptop can overheat from the lack of airflow will be noticeable during operation. You may get temperature warnings from Windows, or the laptop may shut itself down unexpectedly due to the excess temperature. If either of these are the case, you can attempt to clean the fan. If this fails to resolve your issue, please follow our guide to replace your fan.

Dusty Fan or Failing Fan Bearings

Computers can overheat when the fans are clogged with dust or if the bearings within the fan are beginning to fail. Both of these will result in the fan running more than usual and the laptop feeling warmer to the touch. This can cause excess noise, which will likely be noticed, especially when using the laptop for resource intensive tasks. To try to fix the problem, you can remove the backplate, and use compressed air to blow off the fan. You can also use a small brush (like a small makeup brush) to carefully clean the fan. If this does not resolve the issue, your fan is likely defective. Please follow our guide to replace your fan.

Screen is Unresponsive

Portions of or entire screen not visible.

Driver, Bios, or Failed LCD Panel

Computer powers up (power light is on), but screen is black.

If upon starting the computer absolutely nothing is displayed on the screen, and restarting the computer does not resolve the issue, recall if any changes were made to video drivers, or to the system BIOS. Changes to either could cause this issue. If neither of such changes have been made recently, please follow our guide for replacing the screen.

Stuck Pixels or Faulty LCD Portions

If there are black spots blocking the display there may be a dead pixel. If this is the issue your screen will continue to form dead pixels and will need to be replaced. If there are little spots of color that are stuck on the screen blocking the display there may be a stuck pixel. One thing you can try before replacing the screen for a stuck pixel, is playing a video designed to unstick pixels. If these issues are not fixed by the method described, the screen may need to be replaced. If so, follow our guide to replace the screen.

Computer Does Not Read Disks

Disc Drive will not function properly

Complete Disc Drive Failure

Both of these symptoms are likely due to a hardware failure of the optical disc drive. Please follow our guide to replace the disc drive.

Disc Drive Driver Installation Issue

This issue is usually the result of a software failure to recognize the optical drive. Please follow Microsoft’s guide to resolving this issue.

Battery Will Not Hold Charge

The Battery will not charge properly

Gradually Failing Battery

If the Laptop is experiencing issues with charging or holding a charge, a faulty battery is the most likely cause. Please follow our guide to replace the battery

Complete Battery Failure

If computer will power on with charger plugged in, but will not if the charger is disconnected, a faulty battery is the most likely cause. Often windows will show a warning on the battery indicator, indicating it needs replacement.

If the computer does not turn on even with the power adapter plugged in, please check that the light on the charger “brick” turns on when it is plugged in. If this light does not come on, the charger is likely broken. Purchasing a replacement charger will likely resolve this issue.

Unresponsive Keyboard

The Keyboard Does Not Respond Properly.

Residue under the Keys

There may be dirt and dust particles under the individual keys that are hindering the functionality of the keyboard causing the characters to not show up when pressed. You can use compressed air to release the dirt from under the keys. If this does not resolve the issue, follow our guide to remove the keyboard to clean more thoroughly under the keys.
