Laptop power button is on with light lit normally but screen is blank.

Laptop was in sleep mode all the night. When I got up and switched it on, it didn't get switched on and so I shut it down using the power button. After that when I switched on the laptop, the screen is completely blank and black. Literally nothing is there. But the power button white LED light is lit normally with no blinking etc and the laptop is even heating up like normal. The laptop has non-removable battery. So I tried resetting it by pressing power button for more than 15 seconds and also by pressing Windows button+B along with power button, but nothing is working. Plz help.

Hi,

If the drive light (left side of laptop) is lit or blinking:

Try shining a torch at an angle close to the laptop screen to check if you can detect any images when the laptop is on.

They will be very faint if they are there so trying this in a darkened room may help.

If there are images then you have a backlight problem, either in the display, the cable between the display and the motherboard or the motherboard.

If there are no images then try connecting an external monitor to the laptop and check if there is a display on it. Remember to press the 4th Action key from the left (rectangle symbol with lines either side) to toggle the display between the laptop and the external display or both on together. Even a TV can be used as an external monitor as long as it has HDMI inputs and you have the appropriate cord to connect the two together.

If the drive light (left side of laptop) is not lit or blinking:

I realize that you have already tried to do a BIOS reset but if still no good you may have to remove the battery and do a power refresh without it connected., i.e. disconnect charger, remove battery, press power button for 30 seconds, replace battery, reconnect charger, turn on laptop

Here’s the maintenance and service guide for the laptop (if it is a HP Pavilion x360 - 14-ba253cl that is) taken from this webpage.

Go to p.42 to view the necessary pre-requisite steps and then the procedure to remove the battery
