Almost everything on a laptop is fragile and vulnerable to damage from knocks and dropped. However, in particular, two components are more likely than others to suffer damage if a laptop falls, and hence these are the most likely to need replacement at some time during your laptop’s life.
A laptop computer contains the same components or variations on the same features as a desktop computer. On the whole, they are smaller and require less battery power, but they do the same job. What makes them different is that a desktop computer sits on a desktop and is rarely-if ever moved, whereas a laptop is moved frequently from place to place. Worse, it is used on a person’s lap or on a raised surface such as a desk or stool where a knock may cause it to fall several feet.
It can damage the laptop’s hard drive during either a fall or when a computer suffers a hard knock. When this happens, the head that reads the disc’s data can crash down onto it, damaging the disc’s surface and making it unusable in that area. That will lose the data in that sector, and if bad enough, can put the disc out of operation entirely. Solid-state drives have no moving parts and hence are not vulnerable to this kind of damage.
The LCD screen is the other part most likely to break, and unfortunately, it is the most expensive single component in the laptop. When it fails, the liquid crystal drains from where it should be, and you may initially find that you have a patch or stripe that goes black. Eventually, the whole screen will fail if it doesn’t initially. Other failures to the screen may leave lines or patches of white on them, but ultimately the result is the same as it will need to replace.
Can buy screens online for far more reasonable prices than a computer repair company will charge you. Fitting them is more often than not an easy process that requires that you remove a few parts from the case, such as the bezel. The old screen will have to be disconnected first as there usually are several cables that connect it to the computer, and these may even go under the keyboard.
A few essential tools such as a small, magnetized screwdriver will be needed, sometimes with a Torx head on it. Once the old screen removes, putting the new one in place is simply a case of reversing the process-first plugging the screen back in, replacing the keyboard, screen hinges and bezel, and anything else that may remove. I can often found tutorial videos online for specific laptop models.
Of course, other components may damage when a laptop is dropped, including the motherboard. And any of the parts that are solder onto the printed circuit board, such as the charging pin. These, however, tend to be more significant repairs, requiring specialist tools, and are not so suited to DIY repair.
