Frozen mouse

Mouse (trackstick or touchpad) is frozen and does not move.

Disabled mouse

You may have disabled it by accident through the onboard mouse. Try pressing, or toggling, a button near the ball or touch pad to re enable.

Corrupted software

It is possible that your computer is acting up. Try holding the power button to force restart the computer to reset its conditions.

You can also reinstall the touchpad mouse driver through the control panel to reset the mouse to factory settings.

Unplugged/Faulty keyboard cable

If your mouse is still faulty, there is most likely a problem in the keyboard cable. To check your cable, turn off the computer, remove the battery, and unscrew the k screws on the bottom side of the laptop. Turn the computer over, and gently open the lid and remove the keyboard, instructions can be found here. The keyboard cable is located on the bottom near the touchpad. Check the tightness of the connections by swinging the top of the keyboard towards you, gently.

If the connections are loose, try to tighten the connections. If the connections are tight, the cable needs replacement.

Wandering mouse

Mouse pointer moves independently.

Accidental contact

Before we assume there is a major problem with the laptop, examine the way you type. If your palm rests near the touchpad, it is possible that you may be unconsciously moving the mouse as you type, causing it to wander. Loose articles of clothing, such as a jacket or long sleeve shirt, may come in contact with the touchpad cause the mouse to move.

Corrupted software

If the pointer moves independently of commands there could be faulty software involved. Try reinstalling the pointer software.

Corrupted motherboard and touchpad

If the mouse is still wandering, the motherboard and touchpad may need replacement.

Laptop keeps overheating

Your laptop keeps overheating and shutting off.

Blocked vents

First ensure that nothing is nothing in the way of your fan’s vent while you use it. A piece of paper, or cloth, could be cutting off circulation of the computer, causing it to overheat. In addition, if your computer is too close too a wall or surface, circulation can also be cut off.

Warm room

Try to work in a colder environment. Turn your air conditioner up higher or even plug in a fan. Do not force your laptop to work under suboptimal conditions if you can help it.

Overclocking

Overclocking, while useful, can cause the temperature of your computer to skyrocket. If you overclocked your computer, try changing its settings back to the original conditions.

Overworking

Overworking your computer can cause it to overheat. Try to limit the amount of time you spend on CPU intensive programs to prevent overheating. If you feel your laptop getting too hot, take a break and let it cool down.

Debris buildup

Buildup of debris will cause overheating. Turn your computer upside down, and remove major screws. Carefully lift the lid to gain access of the computer’s cpu, fan, and heat sink. Remove as much blockage and debris as you can, then spray each part with a can of compressed air. Ensure you are working in a clean area to prevent dust from entering the laptop.

Faulty fan

After use, your fan can slow or start malfunctioning. If constant overheating ocurrs, the internal fan may need replacement. Instructions to replace fan can be found here

Built in speakers do not work

I can not hear any noise coming from my speakers.

Accidental muted sound

You may have accidentally muted your speakers, double-click the speakers icon in the lower right hand corner and make sure that your sound is not muted and that the volume is not set to zero. You can also use the three buttons that control sound to the right of the power function to check for low volume or muted sound.

Keyboard shortcuts

Pressing the [Fn] and [end] buttons simultaneously toggles your speakers. Continue for several tries to enable speakers.

Updated audio driver

Determine what type of audio driver your laptop has and check to make sure that it is up to date. You can download the newest update at the dell website, or the website or whoever built your sound driver.

External speakers do not work

I can not hear anything from the new speakers or headphones I have.

Accidental muted sound

You may have accidentally muted your speakers, double-click the speakers icon in the lower right hand corner and make sure that your sound is not muted and that the volume is not set to zero. You can also use the three buttons that control sound to the right of the power function to check for low volume or muted sound.

Speaker issue

If you have another set of headphones that you know work, plug those in. If these new headphones work fine, then the old headphones are probably broken. If the new ones do not work, then you probably have a problem with your laptop's audio jack.

Faulty wires

If you mistreat your headphones, the wires themselves could be damaged. If you recently did anything that put large amounts of trauma on the headphones, such as bending them or stretching, then this might be the cause of the problem.

Interference

If your headphones are wireless then they may be experiencing interference. Check that there are no transmitters within ten to fifteen feet of your headphones. If so, remove them, or relocate them to a new area, to eliminate the interference.

Wireless does not work

Your computer is not connecting to the wireless network or your computer cannot find any networks.

Turned off wifi

If you can see the wireless interface but it does not show any connections, your wifi might be turned off. Try turning it on by holding down the FN key and pressing F2.

Wireless drivers

If you cannot find any wireless interface, and/or cannot see the wireless icon on the system tray (the little icons to the right of the task bar), you may not have the wireless device drivers installed. To install the wireless drivers:

- Go to Dell’s support website (click)

- Enter your computer’s Service tag.

- Click on “Get Drivers” and then “Analyze Now”.

- Follow their instructions to install all the drivers your computer is missing

Wireless Card

A faculty wireless card or modulm could be the source of your problem. Replacement guide for the wireless card can be found here .

Laptop will not turn on

Your computer does not turn on at all, or turns on for a bit and then turns off.

Dead battery

If your computer is running on battery, your battery may be the problem. Try plugging it in and powering it on. If the computer turns on then your battery was dead. If after you charge your battery your computer still will not turn on without it being plugged in, it may need to be replaced. Repair for the battery can be found here

Broken charger

Check your charger light indicator while plugged in. If there is no light showing, try using a different wall socket. If there is still no light showing, try plugging your computer in with a different charger, or using a different charged battery to turn your computer on. If your computer turns on, then the charger is the problem.

Faulty hard disk drive

If your computer only powers on for a few seconds and then off, chances are you have a damaged or faulty hard disk drive, and it may need to be replaced.

Memory upgrade problems

If your computer worked prior to a recent computer memory upgrade, the memory may be the issue. Ensure it was inserted correctly and try booting your computer again. If the problem persists, try a different memory stick; if it works, your memory was at fault, if it fails, your RAM may need to be replaced. Instructions to replace RAM can be found here

Missing software

If you recently deleted or changed some software on your computer, you may have deleted software that was critical to your computer running properly.
