Hi Crommy7123,

 

Greetings.

 

One short beep indicatess normally boot but with a blank screen would propose issue with LCD/cable or systemboard especially with the graphic chip.

 

With the ac charger and battery disconnected, press the power button down for 1 minute to drain flea power then maybe left it so for 30 mins to ensure the internal chips are cooled down. 

Connect the ac charger back and use the Novo button to power on and maybe access the BIOS set up screen.

Usually under Configuration Tab is a display option like Power on Display to toggle from auto then save and exit.

 

If the graphic chipset turned bad then it may lead to a systemboard replacement if reworks or reball would not work on the chips alone. Checking on the fan and re application of thermal paste/ pads may help.

 

Update us how it goes for you.

 

Regards
