 Laptop Generation Guide

What to check for when buying a laptop?

One thing that is very important while buying laptops is the generation of the laptop, which generation you are getting depends on how long the hen will lay eggs.

Like if you buy Thirteen Generation then its box pack guarantee is for one year and for the next five or seven years you can run it without worry. The system is not guaranteed to leave the firecrackers as soon as you take them home and turn them on. 

But if you take the first generation, it is already on its last breath, which can cheat at any time, so whenever you go to buy a laptop, you must check the generation of the laptop, the higher the generation, the more life it will have.

"Intel Core Processor Generations Reference"

Think of generation as a simple language model. The lower the generation, the older the processor. In the list given below you can check which generation belongs to which year and how old the laptop is.

1st Generation: Intel Core (2010)

2nd Generation: Intel Core (2011)

3rd Generation: Intel Core (2012)

4th Generation: Intel Core (2013)

5th Generation: Intel Core (2015)

6th Generation: Intel Core (2015)

7th Generation: Intel Core (2016)

8th Generation: Intel Core (2017)

9th Generation: Intel Core (2018)

10th Generation: Intel Core (2019)

11th Generation: Intel Core (2020)

12th Generation: Intel Core (2021)

13th Generation: Intel Core (2022)

14th Generation: Intel Core (2023)

Beware Old Laptops

The attractive ads of laptops worth 10, 15, 15, 25, 000 or even 25,000 that you see on social media are first, second, third generation laptops that are 12, 12, 13, 13 years old. They are either running on Jagag or they are Chromebooks.

Laptop Buying Guide

Laptops should be bought new, but they are very expensive and have very few customers in Pakistan, so if you start buying used, try not to buy a model that is more than five or seven or eight years old.

At least six generation, otherwise it is better to go for eight generation or as much as you can go above it, eight generation also gets quad core processor.

In the processor model, the first letter after the core (i3,i5,i7) is its generation.

. If the i5-6400u has 6, it is the sixth generation

. If the i5-7200u comes with 7, it is the seventh generation

. If the i5-8550u has 8, it is the 8th generation

Keep in mind that while buying a laptop and car, always focus on reliability instead of cheapness, the laptop bought for 15,000 or 20,000 is just putting money at risk, let alone 10 years old hardware. Today's softwares are not compatible with other laptops that are guests of the counting days. Any time it stops and your twenty or thirty thousand is sunk.

Signs of a good laptop. 

Optimal RAM and SSD

RAM: Least 8 GB or greatest 16 GB

If the RAM is 8 GB then it should be in one slot and if one slot is empty then 8 GB can be purchased separately and the RAM can be increased later. Hard disk ie memory should be SSD. HDD is three generation and also consumes more battery so only SSD is better for the job while generation five six or above is better. The sweeter it is, the higher the generation, the more modern the machine.

Processor Types and Tips

3 types of processor:

core i3, i5 & i7. While  i7 is the best

If you want to do graphical work, a graphics card of at least 2G is also necessary.

The battery should be lithium cells. Also see how many milliampere the laptop battery is, if you take the top, you can be satisfied that how many milliampere the used battery is left in milliampere.

While buying a second-hand laptop, most of the fraud is in the display, that is, the original display is removed and a local one is inserted. While selling the old laptop, the shopkeepers put such a wallpaper that people are happy to see the display and the wallpaper is also like this. Sometimes the damage is not visible on the pixels. The way to check it is very easy if you are looking to buy a used laptop then this information is for you.

Laptop Inspection Checklist

Second, search for the laptop you want to buy on the internet and check its specifications whether it has an LED display or whether it is LCD or LED.

If it is LCD, the display is not visible when viewing the screen from the side, this is a sign of LCD

And led is much better display

Another important question is whether any button of the buttons is damaged

This is a 1MB software, download and install it, open it and press the laptop buttons one by one.

Whichever button is correct will turn green on the screen.

CPU-Z Guide for Processor Identification

To check the processor you have to search in google

CPU Z

Download and install this small software and open it. After opening it, CPU information will be listed in the first option.

In this, the number listed in front of the name column in the CPU information will tell you the generation. Understand it carefully

 For example

Inter core i3,

After that, if there are three more digits, the processor is first generation. If there are four digits, it is second or next generations.

For example

Intel core i3 803

That is, if three digits come after i3i, it means first generation

Intel core i3.,,,, 2304

In this model, i3 is trailed by four digits, so this is the subsequent age

Similarly

Intel core i3.,,,, (3)405

Inter core i3.,,,, (4)505

These two examples also have four digits, but in the first example, the starting digit is 3, so it is the third generation

In the subsequent model, the beginning digit is 4, so the fourth era. 

Remember that round brackets have been added to explain the first digit

CPU. Z

With the help of the same software you can also get information about the motherboard and cache memory and the same software will also give you RAM information and graphic card information. If the laptop does not have a graphic card, the information will not be visible.

A note is also written below, if the hard disk is fine, it is told, if there are problems, bad sectors are written in the note.

Temperature option

InIn the temperature choice of a similar programming, you can track down the temperature of the hard plate

Smart option

All other hard disk tests can be seen in Smart option.

"Verifying Battery Status and Hard Disk Health"

The smart option should have a test value of 0. If the hard disk has been repaired or the bad sectors have been fixed by a mechanic, the bad sector value is not 0

Information option

In this option you can see what type of hard drive you have SSD or HDD etc

How to Check the Battery

Open Windows PowerShell by right-clicking on the Start menu.

How do I check my laptop battery health?

Checking Battery Status via PowerShell

In it you have to type it yourself.

powercfg/batteryreport/output

Next is to type

-c:\battery.html-

After that you have to press enter and then click save battery report. Your battery report is saved in C drive, open it and see the battery information. This report shows how much battery there was when the laptop was made new and how much battery is left to use now.

note After so much caution, first of all, no one will give you a laptop because the shopkeeper uses these things to apply lime and if found, your four days will be cut with coins. After all these precautions you become chalk free. If the shopkeeper is good he will satisfy you otherwise next shop.
