There is a fault with the laptop. As soon as you turn on the laptop it starts flickering and fluctuating. At times the flickering stops for a moment but then it starts again almost immediately For this reason I am selling as spares with no returns. The fault might be with the graphics card or screen or screen cable but I cannot say for sure
The specs of the laptop are
Intel core i5 10th gen 10210u
16GB Ram
256gb ssd
Working Battery
Original Lenovo charger
Windows 10 pro pre-installed
