My laptop output device failure
I installed Ubuntu Linux in August last year, and since then my laptop has been experiencing serious hardware and functionality problems. At first, everything seemed normal, but after some time different input devices started failing one after another without any clear reason. The first issue was with the trackpad, which suddenly stopped working. After that, the touchscreen also failed completely. Not long later, the built-in keyboard stopped functioning as well.
Because I did not have enough money to replace the damaged parts, I decided to continue using the laptop with an external keyboard and mouse. For a few weeks, the system worked properly again, but eventually more strange problems began to appear. The external keyboard started working inconsistently, sometimes responding normally and other times failing completely. The mouse buttons also began malfunctioning, with the right-click behaving like a left-click. After that, more functions kept failing and the laptop became increasingly unstable and unreliable.
Thinking the issue might be caused by the laptop hardware itself, I removed the hard drive and installed it into another computer. However, the exact same problems continued on the new system, which makes me believe the operating system or drive may have become corrupted.
