Samsung 300V5A i7 kannettava tietokone

Selling a laptop. It worked fine for a long time. The battery is old and does not hold a charge well, so the laptop was usually always used with an external power supply. One screen hinge is loose and has play. There is an additional memory bar inside (2 in total). One day a message appeared on the screen (screenshot on a blue background). After rebooting, the laptop no longer turns on. The screen blinks every 2 seconds, it cannot start loading Windows for some reason. In an attempt to solve this, I bought and installed a new Verbatim 128 SSD (there is a payment receipt in the photo), but this did not help. I did not look for the problem further, so I am simply selling this laptop.
