2. Prolonging Laptop Lifespan
There are several things you can do to increase the lifespan of your laptop:
1. When left in cold places, allow your laptop to become
accustomed to room temperature first before turning it on. This
prevents any condensation, subsequently avoiding short
circuits.
2. To prevent any dust from accumulating in the vents, always
place your laptop on top of a clean, flat surface.
3. By preventing dust from entering, you’re
also preventing heat buildup. To assist in
preventing heat buildup, always make sure
you have proper ventilation – again, place
your laptop on top of a clean, flat surface.

direct sunlight. This prevents any damage to the internal
components. They are very costly to repair.

heavily padded bag to prevent any accidents.

4. Cleaning Tips
To prolong the laptop’s life even more, cleaning must be an essential part of your
routine. It’s important to follow these tips:
Keyboard
It’s important to clean them from time to time, preferably
once every few weeks, or once a month. Keyboards become
hosts for germs, crumbs and dust. To clean them, use
compressed air, because you can get into those hard to reach
places easily.
To improve your chances, you can get a keyboard cover, or
use a full keyboard when you’re at home.

5. Cleaning Tips
Screen
Apply some alcohol to a cotton ball to clean the edges. The
quick evaporation of alcohol prevents any liquid from
seeping into the cracks.
You can also use a warm, lightly damped cloth. You’ll be
able to remove any stains with ease. Also, remember to not
use excessive pressure, or else you’ll risk puncturing the
screen.
Body
To clean the rest of the body, all you need
is a soft piece of cloth to wipe away dust.
This will also prevent any scratches. If
there are any stains, just apply some
alcohol and it will quickly go away.

6. Conclusion
The aforementioned tips here are plenty, and it’ll definitely help keep your laptop
in top condition.
