Other Issues

- Boot Issues
If the computer boots sporadically or doesn't boot at all, critical portions of the hard drive may have been damaged in a drop.

- Power Issues
Connection problem between the power jack and the motherboard happens easily if the computer is dropped and lands on the power cord connection while it is plugged in.

- Issues like wireless adapter or a USB port might suddenly stop working after a drop or a DVD drive might start groaning every time it spins a disk etc.

Damage by liquid

Outer (exterior) damage

This sort of damage is usually visible due to lightened, discolored or darker areas in the screen.

Inner (interior) damage

This sort of damage is mostly not visible for regular users. Anyway also this can lead to malfunction of the notebook due to e.g. corrosion.

3rd party damage

Damage on keyboard

Damages on keyboard can vary from being simply dirty, vanishing letters up to missing key caps.

Unauthorized repair

Damages caused by unauthorized repair attempts are mostly visible on corrupted housing, incorrectly implemented parts or just wrong repair operation.

Cables and power supply

If storing the power supply and its cable incorrectly it may happen that if using your damaged power supply it leads to your laptop being hot and you may even smell something that is burning up.


Scratches and similar surface damage happen easily and can vary from small scrapes up to deep scratches caused by various objects.


Touching your LCD screen with your fingers or with a sharp object can cause lighter or darker areas or white / black spots visible on the display.


If not shut down correctly while carrying your laptop in your laptop case, the produced heat can cause curvatures on the laptop surface. As well if your laptop gets overheated it may happen that parts inside the laptop get burned.


When trying to insert a cable with an incorrect object ending you might damage the interface input. The result is: interface is not working (well).

LCD screen

Obviously, when the internal glass got cracked and liquid crystal started to leak inside the display panel along the crack. In some cases, you will be able to see the broken glass and black and white blotches.
