Is there a lifetime limit for the laptop s built in SIM card? If so, how long is it?

Of course there is a lifespan.

However, the current hardware design and quality are very good.

General machines will not have such problems until they are scrapped.

The computer can effectively protect or prolong the life of the machine or hardware by paying attention to the following problems in the process of functioning:

1. When the machine is not in use for a long time, turn off the power directly instead of standby.

2. When the machine is working, try not to move.

3. After a period of time, clean up the garbage in the chassis.

4. Waterproof, drop-proof, dust-proof, when used in the above environment, try to protect the machine, dry and remove garbage regularly.

Hello! First of all, we have to figure out one thing, which is the wireless network card you are referring to?

There are two kinds of laptop wireless Internet access, first, the built-in LAN module, which is used to receive wireless routing!

This is mostly the book that comes with it.,Pre-installed inside the notebook!

As long as it is used with wireless routing, there is no expiration date until it breaks!

Second, the wireless network card needs to be consumed, and there are two kinds of China Unicom CDMA and mobile edge!

It costs money, buy equipment first, and then buy the tariff, and the service period is determined according to the tariff, ranging from a few months to a year!

And in your words, you can conclude that what you want to ask belongs to the first situation, so, where there is a wireless router, you can get on it if you have a password, if the route does not get a password, then you can directly click on the connection, generally speaking, how long does the motherboard take, how long can it be used when it is stuck on that machine.

Look at what brand of battery, initially it is generally standby for 2-3 hours (above medium quality), battery, manufacturers generally only guarantee for half a year, it is conceivable how long the life is, and one more point, according to the instructions for normal use of the battery, it can be used for at least one year, anyway, the longer the time is used, the worse the battery life will become, any brand will be like this.

Generally about 4 years, you can use it, but it takes 4 years, the performance is a big piece of poor performance, if you just surf the Internet or something, you can barely use it, but after a long time, the display will be yellow, not so bright, the keyboard will gradually fail, all parts will age, then it depends on how strong your machine is, the general computer is good for a year.

Due to the relatively high requirements of the manufacturing process of the notebook computer, generally speaking, its hardware rarely has too many problems within 5 years (unless it is often turned on for a long time, you should know that the heat dissipation of the notebook is limited, which cannot be compared with a large computer), but in the notebook computer, the LCD screen is generally the first to have a problem, the normal service life of the general LCD is 4 to 5 years, and it is not bad after this time, but there will be uneven color, In recent years, the newly launched high-brightness liquid crystal has made great adjustments in the process, so that its life has reached 7 to 8 years, but the general conservative life is 7 years.

Laptop lifespan varies from person to person and from machine to machine.

My experience: More than ten years ago, a Sony V505 Centrino notebook was used for two years, the hard disk was broken, and then the motherboard was broken and could not be lit, and it was scrapped; Another Toshiba's M50 Centrino notebook was eliminated from the main position due to speed after 4 years, but it is still in service (currently a learning machine for children), with no repair history, and it has also entered coffee once, and it has not affected its life when the power is dismantled and dried in time.

07 a Dell D420, the LCD screen was broken and replaced during the warranty period, the motherboard did not light up after the warranty period, minor repairs, and then several keys of the keyboard failed (the motherboard did not light up and the keyboard failed, it is estimated that it was caused by water dripping into the tea drink, and there were nails-sized corrosion marks on the motherboard board), which has been abandoned due to the speed of the hard disk and the keyboard buttons, but it can still be turned on and used.

In 09, an HP has been used as an office computer since then, and only the SSD and memory have been upgraded.

A Lenovo Yogo 11s for 13 years, so far in use, small problems continue, gravity induction failure, touch screen failure, etc., every time it needs to be restarted to solve.

Let's talk about another example, the HP and YOGA11s that my colleagues entered at the same time, because of smoking and drinking, etc., the computer has long been scrapped.

In short, the life of the computer is related to the quality of the machine, the hardware configuration, the use environment, the user, and the user's software requirements.

Generally, the lifespan of notebooks is 3-5 years.

Those who are slightly good at maintenance can use it for a longer time.

This depends on the use environment and usual maintenance, I have used a notebook for 8 years.

The low-end will be eliminated in 1 to 3 years, and the mid-to-high-end will be eliminated in more than 5 years.

How long does a laptop last, and how many years can it be used in general?
