Nobody Tells you when you buy a new laptop / notebook computer........
The unfortunate truth to laptop failures is latent heat. 99% of laptops fail because the cooling coils or fans become compacted with lint and dust.
Depending on how often you use your laptop, you "should" continually maintain the cooling system on a regular basis. Compressed air blown from intake and exhaust sides of laptop once per week for daily use, once per month for infrequent use, once per quarter for very infrequent usage. Dust, hair (yes hair, human and pet) lint, dander, or any airborne particulate manage to find a way to the intake side of your cooling fans thusly collecting inside the cooling chambers and fins. Never allow a laptop to run on a soft surface such as a bed, lap pillow, or carpet. Contrary to the name laptop, it is not designed to be operated on any surface other than a clean, flat, rigid surface.
Avoiding problems..........
A small piece of pantyhose taped over the air inlet of your laptop will help to reduce the size of particulates introduced. The fine mesh will allow adequate air to cool the laptop and can be easily cleaned with a soft brush or replaced with a fresh piece. The pantyhose filter "must" be checked upon first use each time to ensure that it is not impacted..
Fixing problems....
It is also common practice for some technically minded people to disassemble their laptop once an issue presents itself.
There are a number of YouTube video that demonstrate disassembly procedure. Most are very helpful and model specific or very near the same.
Make sure you have some isopropyl alcohol,thermal compound, and a clean soft brush before you begin your disassembly.
Always make it a practice to remove heat sinks and heat sink fans and do a thorough cleaning of same.
Always clean the mating surfaces of the heat sink and processor. CPU and Video processors. Dual heat sinks will identify both are present.
Always apply fresh thermal compound to processors after the cleaning process before reassembly.
Always use the correct tools for disassembly. Precision screwdriver set and guitar pic or other plastic spudger tool.
Why does heat cause failure?
The first components to go generally speaking are capacitors. Capacitors have a Fahrad range along with a Voltage reference typically maximum voltage. Capacitors also have a heat range typically between 4C-85C degrees or 34F to 185F degrees. The problem with heat is that it dries out the capacitors ability to filter and store voltage. Ceramic and Polymer capacitors either burn or crack while Electrolytic capacitors bulge or explode when they fail.
The next most common heat related problem is deballing. This happens when the solder ball joint begins to melt where a surface mounted component was soldered to the motherboard during the flow solder process. Most common faults are noticed on video graphics processor mountings.
Charging and Battery Failures...
Many mass produced laptop computers are spit off the assembly line with poorly anchored charging ports. For normal everyday "gentile" useage they will last the lifetime of the laptop. More often than not a laptop will be picked up with the charging cord still attached, or knocked off a work surface with the cord still attached and that places overwhelming strain on the charging port attached to the motherboard. Continued use of a loose charging port will (not sometimes) lead to complete failure.
If you are technically minded, you can disassemble your laptop and replace the loose charging port with a new part. If you are not so much into soldering, and your port still works, but disassembled your computer to clean it.. you might want to try putting a dab of hot glue inside the computer at the joint. The hot glue can be removed later by a qualified technician if required.
Faulty charging ports destroy a battery over time. The typical laptop battery is a lithium ion battery that is meant to be depleted, then fully recharged. A faulty charging port will only partially charge a depleted battery and thusly train the battery to unacceptable charging and ruin the battery for good.
To answer your question specifically I would go back inside the laptop (yes, again) and perform the steps I have outlined. Ensure there are no pinched ribbon cables or molex plugs undone. The laptop can be tested before complete reassembly to check the display.
