[GS8888]

Good morning
I want to buy use laptop HP ZBook
How can I find out how many years the laptop has been used?
I did not get an answer to this question in the shop because they told me that this laptop HP ZBook had been used for 2 or 3 years
They told very unsurely that's why e I want to know how I can check this information myself

Can I find the production year of the laptop HP ZBook for his unique number?

Hi:

Yes, you can tell exactly what year the notebook was made, down to the week of production.

Look at the serial number.

The 4th, 5th, and 6th characters will always be numbers.

The 4th = the year of manufacture (0-9)

The 5th and 6th = the week of manufacture (01-52).

For example, if the 4th, 5th and 6th characters of the serial number are 812, that means the notebook was made in 2018 during the 12th week of the year, which when using a calendar converter would be during the week of March 19 - March 25, 2018.

I have the next numbers for my laptop

My Device HP Notebook - 15-da0482ur
Product 8TY00EA
Serial CND94212YT
Model RTL8723DE

I have to take "Serial CND94212YT"

> The 4th, 5th, and 6th characters will always be numbers

The 4th, 5th, and 6th characters are 942

It means that my laptop was produced in 2019 in 42d week

It is Monday, 14 – Sunday, 20 October 2019

Did I understand you true?

[Paul_Tikkanen]

You are 100% correct.

Your notebook was made during the week of October 14 - October 20, 2019.

Thanks a lot

I will know now how I can find out when the laptop was produced. It is great. Thank you very much

I really want to buy this laptop but I don't want to buy a very old laptop

I want to buy a used laptop that will work for 5 years

[Paul_Tikkanen]

You're very welcome.

A notebook made in 2019 should be able to run Windows 11.

[GS8888]

Maybe but I use Windows 10 Pro and I like everything

I don't like only 4 GB RAM in my laptop

It is very small for my job

I have one question

If a laptop has 4th character 1 or 2 it is 2011/2012 or 2021/2022?

[Paul_Tikkanen]

You'd either have to know:

The decade you bought the notebook in if it is new.

If you have no idea about anything, then you would have to look up the specs and see what processor and whatnot the notebook came with.

For example:  if the year of manufacture was a '1', it could be 1991, 2001, 2011, or 2021.

If the processor was an Intel 10th generation core processor or a Ryzen 4xxx series, then you would know that such technology didn't exist in 2011 or before.

If it was a Pentium II processor, then you would know that it could not be any newer than 2001.

I never knew when a processor was produced because I never learned these questions
