To determine the dimensions of a 58-inch TV, it is necessary to be aware of what the ratio is of the display. The majority of televisions currently in production come with a 16:9 aspect ratio. That means that if you divide the screen’s height in half by the width of it, then the result that is obtained is 16:9, which is roughly 1.78.

The aspect ratio is identified by the features on the screen

Today’s televisions that have HD or full HD as well as Ultra HD (also known as UHD or 4K) resolutions typically come with a 16:9 aspect ratio.

Older TVs that have standard SD (Standard Definition) resolution feature an aspect ratio of 4:3 ratio. But, this format has been discarded to allow for high definition TVs with 16:9 aspect ratio.

The term „58 inches“ is the its diagonal. If we measure the length in centimeters it’s the equivalent of 147.3 centimeters.

If the aspect ratio of 16:9, then the screen’s width is 128.4 cm, and it’s height 72.2 centimeters.

The following image shows dimensions of a 58-inch television with a 16:9 aspect ratio.

In the past prior to the advent of high-definition display (HD, Full HD and Ultra HD), the most popular televisions were sized with the aspect ratio 4:3. The width was 1.33 times the height.

Based on this aspect ratio, an 58-inch TV is 117.9 centimeters in height and 88.4 cm in height , as the image below shows. It isn’t common to find the kind of TV that has the number of inches.

What is the best way to upgrade or replace the battery inside your MacBook Air?

Posted on by

The battery that is included in every MacBook Air models is „integrated,“ that is to say it is not intended to replace by customers and isn’t „swappable“ like the battery in „pre-Unibody“ MacBook and MacBook Pro models.

It is true that the MacBook Air battery is replaceable but it’s not easy. Thankfully it doesn’t require soldering and Apple did not hold the battery to the case by using adhesive or adhesive, neither.

Official Replacement Option

In the official sense whenever the battery life for each MacBook Air drops enough to warrant the need for replacement — or is no longer covered by warranty, one is required to supply Apple with the complete MacBook Air for service.

More information is available on the company’s website and prices vary in various countries. However, in the last time it was update, it’s priced at USD$129 within the US as well as C$149 within Canada (originally 209 dollars), PS99 in the UK (originally PS159), and A$199 in Australia (originally A$229) to require Apple repair the battery (including batteries).

If you are close to the Apple Store, you can choose to have same-day service by making an appointment. If not choose to visit an Apple Store, you could get the battery replaced via mail, which can take 3-4 days.

Self-Replacement Option

Although it’s somewhat of a stretch to talk about replacing batteries as an „hack“ per se, because it’s quite simple you can easily to replace the battery on your own.

The battery replacement yourself will not only save some cash however, it can also help you save time. It can also be more secure since you’re not required to hand over the entire notebook over an outside company. But, make sure that you purchase a good battery. A battery that is not of the highest quality may not be able to hold a charge the same amount of time as a premium one, however, it could leak, or even trigger an explosion.

AnandTech is the very first to detach MacBook Air’s original MacBook Air and discovered that it’s not hard to change the battery, but it will require the removal of 19 screws.

The replacement process is very similar to the following models. But, beginning with the „Late 2010“ series, Apple utilizes 5 point „Pentalobe“ screws (which some call „Security Torx“ screws) on the outside to severely discourage users of „tinkering“ with their computer. The battery assembly is also fitted to the computer using the T5 Torx screws. It’s not that difficult to change this battery on these kinds of models, it only requires a screwdriver that is more obscure.

Battery Replacement Summary

Anyone with a little technical expertise can easily change the battery in this MacBook Air models themselves if they decide to make the change. The replacement of the battery is only a quality, compatible battery and the appropriate screwdrivers or screws.

It is not enough to stress that it is vital to choose a good battery. Batteries that are not of the highest quality may not be able to hold a charge longer than a high-quality one, but they could be leaking, swell or even cause fire.
