T440s (Win10 64-bit) has 5 short beeps, black screen when I try to wake it up from sleep. I have tried to press f2 multiple times when i turn on the laptop but since the screen shows nothing, i guess i am unable to enter the bios setup. The screen is just black. in MacBook Pro by Macbook air suddenly doesnt turn on. When i first put all the parts together and powered it on i got a normal start up and my screen took me to the Bios. The black screen goes on forever. So I again turn my pc off via shutdown, remove the card, and check it, everything seems fine. Windows 7 Thread, Compaq Presario CQ56 Notebook PC turns on but it won't show anything on the screen in Technical; My Neighbors laptop Hard drive Failed. How many beeps do you hear in a repetitive pattern. So I turn it off, check the fan, clean it of dust, and turn it back on. Her computer has an AGP GeForce 6200, I also had the same card.
