A common misconception of this keyboard problem is that it is caused by a virus as the user loses control over the keys.
Most causes of keyboard failure involve dust and rust build-up and accumulation over the years. Or it could be from a liquid spill or leak that many computer users may not even be aware of.
It’s also common for a computer that hasn’t been used for months to end up with a faulty keyboard as well if it’s not stored in a cool, dry environment.

So even if it’s just a few keys that don’t work, you’ll have to replace the entire keyboard. If your keyboard has keys that have fallen off, try reattaching it.
Unfortunately, there are no single key replacements if it wears off and doesn’t fit back on the board. You will still need to replace the entire board if you still want to fix the keys.
One thing to note is that if your entire keyboard stops working all of a sudden, it could actually be a motherboard problem instead.
When a keyboard malfunctions, it is common for some keys to become unresponsive or output random characters while other keys work normally.

For laptops, the touchpad is usually the main component for controlling the mouse cursor. Once the touchpad starts to fail, it can cause the cursor to jump around randomly and erratically.

So if your laptop is connected to a mouse and the cursor still moves around as if it has a life of its own, your touchpad is most likely faulty. This would require a touchpad replacement.
What causes this error is quite similar to what causes keyboard errors. The touchpad gets damaged over the years with the accumulation of dust, rust, moisture.
Fluid spills and leaks are another very common cause. The touchpad usually has a small hole around it, and this is where liquid can leak through damage to its PCB (printed circuit board) underneath.
Using excessive force when pressing the touchpad button can also cause damage to it over the years.
Hardware For The Programmer
Screen damage can look like many things. The most characteristic are physical cracks on the screen along with image distortion.
These distortions look like vertical lines across the screen or a bleeding image. Sometimes an image distortion can mean a video card problem.
If you can still get the screen to appear on an external monitor, you can confirm that you have a screen problem and not a video card problem.
The majority of screen damage is physically caused by end users: dropping the computer, stepping on it, or grabbing the edge of the screen while picking it up instead of normally carrying the laptop up from the base. A very familiar one that we have found is to forget something on the keyboard and then close the laptop screen.
Five Most Common Laptop Problems And Their Solutions
Think of the screen as your TV, how long does your TV last? Probably years, a very long time. Computer and laptop screens tend to last for years just like your TV… until you break. ?
A video card, also called a graphics card, works to generate the image feed for your screen. This can be for your laptop monitor, computer monitor or a connected TV monitor.
There are a few different ways to tell these apart. Distortion caused by video card failure looks more like vertical bars (sometimes horizontal). The keyboard and mouse may also become unresponsive during a video card error. Connecting to an external monitor won’t work as well.
To fix this problem, replace the video card. Most newer laptops have video cards built into the motherboard, so it can be more complicated to repair. You must replace the entire motherboard to replace the video card. For desktops and some laptops, you can only replace the separate video cards.

Why do video cards fail? Video cards are generally expected to last 2-5 years. Accumulated dust and rust inside the video card leads to overheating problems for the card and eventually kills it. Heavy gaming, overclocking your computer can also put a lot more pressure on the graphics card and reduce its lifespan.
If you like gaming, be prepared to invest in another video card in a few years! Think of video cards like cars: high-performance cars with powerful engines usually don’t last as long as a regular car (like a Toyota Corolla). Video cards are very similar in this aspect.
Most computers use a fan system to keep it at a normal operating temperature. This prevents overheating that could damage the hardware inside.
Moving parts like fans almost never operate silently, you will always hear a very low hum from the rotors while your computer is on. But when it starts making abnormal clunking and rattling noises, you’ll know the fan is worn out. Getting a replacement would solve this problem.
Vital Computer Maintenance Tips And Checklist To Protect Your Device
Overheating can lead to more serious damage that can cost you much more than replacing the fan. So when you find that your fan isn’t working well enough to keep things under control, it may be worth stopping the problem from there. This can help you save the money that additional problems caused by overheating can cost you.
Again, this fan noise is caused by a buildup of rust and dust inside. This rust causes its engine to wear out. Like a pedestal fan, it has a small motor and fan blades. Computer fans are made the same way. After years of use, your computer collects dust and its fan is clogged. Computing in a clean environment can make a big difference!
Laptop batteries will degrade over a few years. It either starts to not last long or won’t hold a charge when plugged in. It also needs to be replaced.
Batteries usually only last 2-4 years. After you’ve had your laptop for a while, it’s very likely that the battery is dying if it doesn’t last long or hold a charge. It’s surprising that many people don’t expect their laptop batteries to fail!

Here are the facts: Batteries are consumable parts, every battery will eventually wear out and need to be replaced. AA, AAA batteries, car batteries, phone batteries, GPS batteries and batteries for your laptop will wear out and eventually fail.
