My problem is that I cannot suspend my computer properly. Technically I can, but when I come back and try to reopen it, it just doesn't work. My screen remains black with a blinking line, like a typical writing line _.

My laptop is a HP Pavilion 15-BC519NS Intel Core i5-9300H/8GB/512GB SSD/GTX 1050/15.6".

I haven't seen a fix for this anywhere, so I was expecting someone to help me here. Thanks in advance!
