The keyboard isn't functioning correctly
The keyboard doesn't seem to be responding properly.
Ensure there is power to the computer
Make sure the computer is on. If your computer powers on and the keyboard is still malfunctioning, you have a different issue.
Check the Caps Lock key
If all the letters you're typing are capitalized, press the "Caps Lock" key. If the letters you type continue to come out capitalized, you likely have a damaged Caps Lock key.
Check the Number Lock key
If the right set of number keys aren't outputting numbers when pressed, press the "Num Lk" key. If you have pressed the "Num Lk" key and you are still not able to type numbers out of the number pad on the right side of the keyboard, you may have a damaged "Num Lk" key.
Keyboard is completely nonfunctional
Restart the laptop. If the keyboard still does not work, there may be some problems with the internal wiring, and the keyboard may need to be replaced. Turn off the laptop and replace the keyboard.
There is no sound
No matter what you do, you can't get your computer speakers to work.
Unmute the computer
Hold "FN" key and press the "ESC" key. This command is supposed to unmute the audio output of the laptop. If you have tried this command and you still cannot output sound, you may have an issues with the actual speakers.
Another suggestion is to see if your speakers are muted on the bottom left corner of your screen. If the speaker has a red circle with a slash coming out of it, the speaker is muted and you should attempt to unmute it by clicking the image of the speaker in the bottom left corner and removing the mute setting. If you have done this and you are still having issues with getting output from your speakers, you likely have damaged speakers.
Ensure the volume is turned up
It is possible that there is no sound because the volume is turned down. Rotate the volume scroll wheel to the right on the bottom edge of the laptop facing you. If you are still experiencing a lack of sound, you may have a hardware issue with your speakers.
Check for external speakers or audio devices
Make sure there are no external speakers or audio devices plugged into the computer. External audio devices such as headphones, customs speakers, etc., cause your internal laptop speakers to stop outputting sound. If you have removed all external audio devices and you are still experiencing issues with audio output from your laptop's built in speakers, your laptops speakers may be damaged.
Damage to speaker hardware
If the sound does not work, there may be a problem with the internal wiring/speaker, and you may need to install a new speaker.
Computer is slow and unresponsive
Close unnecessary programs
Having too many programs open can slow down your computer. Make sure that you close all the easily visible programs that you have running. If you have closed all easily visible programs, another suggestion is to use the CTRL-ALT-DELETE command and check to see if any unnecessary background programs or applications are running.
Too many programs might be running in the background of your computer. Restarting your computer can kill these programs and free up the computer's processor. If you are still experiencing slowdown issues after you have restarted the computer, try closing background programs using the CTRL-ALT-DELETE command. If you have done this and you still feel that your computer is running slowly, you likely have a hardware issue.
Check and maintain the RAM
Having RAM issues can cause a computer to run slowly, with the computer taking long periods of time to open programs and run commands. Before you out rite replace the RAM, there are a few things you should do first to make sure the RAM is the issue. First, open up the task manager and a program that you are experiencing slow down issues with. Check to see how much memory you are using with the task manager. If you are using a high percentage of RAM, you likely have a RAM issue.
One way to alleviate slow down issues is by adding more RAM.
Adding more RAM will allow you to run more programs simultaneously without a decrease in performance.
Hard drive issues
If you cannot access your files or it takes them a long time to load, you may have a problem with your hard drive.
Hard drive running slow
While this is a common problem, it may not actually be a hard drive problem but a problem with the OS. Defragmenting the drive will fix many slow hard drive problems.
Hard drive not recognized
If your computer does not recognize the hard drive, you will have to open your bios during the computer's start up. In the bios, ensure that your hard drive and disc drive are enabled. If your hard drive isn't recognized as the primary C drive, check your bios and run the bios disks that came with the hard drive.
Computer turning on then shutting off
If you turn on your computer and it shuts down immediately upon boot up, your hard drive may be corrupted and you may need to replace it or format it. If you are going to replace you hard drive, you will need to purchase a 2.5 inch hard drive.
Computer battery life is shortened
Is the computer's battery capacity much smaller than it used to be? Does your computer fail to respond to the power button being pressed? If so, your problem may lie with the power systems of the laptop.
Logic Board Fault
Turn off your laptop. Plug in the computer using the power cord supplied by the manufacturer. Remove the battery and try to boot up the computer.
If the computer can boot up without the battery with only the power cord plugged in, the power problems lie with your battery. This problem can be easily fixed by replacing your battery with a new one. You can purchase a new one to replace your older battery.
If the computer cannot boot up, then there is something within your laptop that has failed that would be too difficult and expensive to repair.
If your battery (or the plastic housing it is in) has any physical deformities (bumps, bulges), remove the battery and stop use immediately. Recycle the battery with a e-waste management company and replace the battery. Do not use that battery; there is a high chance that it may leak caustic chemicals or blow up.
LCD Screen Problems
Screen is not displaying the correct image or may be dimly lit.
Screen is Dim
If your screen is dimly lit or has a light pink hue or the light, the CCFL tube may have to be replaced. Before you can be sure, check to see the screen brightness setting for your computer by moving your cursor to the lower right segment of the screen. Once your cursor is there, click on the brightness setting button to see what settings your computer currently has in use. Make sure your computer is not on a low brightness setting or in a low energy mode. If your computer is not set to a low brightness setting, you likely have and issue with the CCFL tube and will have to replace it.
Screen is Displaying Colored Lines
To ensure there is no problem with your motherboard, connect your laptop to an external monitor. If the problem is no longer present and you are able to output the display to the external monitor, your LCD screen is broken and will need to be replaced. If the problem persists then this means you will likely have to replace the motherboard in your laptop.
If your screen is flimsy and falling whenever in use, the hinges have most likely worn and will need to be replaced.
Laptop won't Come Out of Sleep Mode
If your laptop hinge is broken and your computer won't come out of sleep mode try pressing the power button to wake your computer up. If this does not work than a full is necessary.
