Default Display Adapter Issues

Hi

Just got my laptop from the service center. There was an issue with the hard drive so they replaced it. I bought it last June. It has dual display adapter; Intel Graphics 620 and a video card AMD Radeon 520. Now after the repair, the default display adapter shows "Microsoft Basic Display Adapter" . I opened the device manager, looked under display adapter, the Intel Graphics 620 was gone. The AMD Radeon 520 is there and the Microsoft Basic Display Adapter. Does that mean the Intel Graphics was replaced?  Should I return the laptop to the service center? I want the Intel Graphics 620 back. any advice? Thanks in advance. Cheers!
