The files on either a SSD (Solid State Drive) or traditional spindle HDD (hard disk drive) can be retrievable if BitLocker encryption is disabled. I assume that your 5-year laptop is using Microsoft Windows 10 and therefore you would have a Microsoft account with a @hotmail or @outlook.com domain name. You will have to access the keys to the “computer name” of your laptop to retrieve the files.
There are multiple scenarios in how a computer technician could retrieve your files depending on what the laptop operating system is and if the technician has the equipment to connect to a SSD drive or traditional HDD. @PhotoGuy you will have to provide your Microsoft account credentials and access the 25-digit key to the “computer name” of the laptop assuming your laptop is running Windows 10.
What information are you specifying the technician could retrieve?
In the Windows XP era, copying files from HDDs was easy. After the introduction of BitLocker in Windows Vista & beyond, encryption of hard drives have made the task of copying drives a lot more difficult.
Well, SSDs & HDDs are secured now so retreiving files has become more difficult for nefarious people to access.
You will need to access your Microsoft account on a web browser on another computer and see if you can get the 25-digit key to the “computer name” of your Windows 10 laptop. I had to supply this 25-digit key every time I swapped my 256GB SSD drive with my 512GB SSD drive.
