I will like to know the date of manufacture of my thinkpad E595 laptop with serial # *********

Mod edit: Serial number masked to prevent mischief

Hello guest8625,

Welcome to Lenovo Community
The manufacturing date is usually printed next to the serial number on the laptop's sticker.
Check the bottom of the laptop.
Another option, inside Windows>System Information>System summary window>BIOS DATE/VERSION provides the name of the manufacturer, BIOS version and the date the laptop was made.
Hope this helps.

Regards,
