Yesterday morning we shutdown the notebook as normal. It hasn’t shown any
error. When we started again in the evening, it boots properly and after
that the matitor turns black and it is not displaying the welcome
screen. But all the lights at the bottom are glowing blue. We tried few
times and the same thing happens again.
Please kindly help us or suggest us for further cattact

Few things to try
Try entering safemode – usually tapping the f5 key when starting up – then select safemode –
if this works and you get a display – go into the device manager (press the windows icon button plus the pause break key – then select hardware > device manager)
click on the plus next to the display adaptors – highlight your display adaptor then right click on it and uninstall)
restart your conputer and see if this helps
if you enter safemode and the display switches off – try entering the bios – when you get the splash screen it should tell you which key to press (enter setup)
does your screen go blank in this – if so you have a hardware problem -
if you can check your setting within the bios – load the optimised defaults or defaults and try again
give this a go and good luck
PS – also try a ATX reset -
remove your battery and the power cable from your laptop
press and hold the power button in for about 30 seconds – this will remove any static build up on the MOBO
Power back on and see if this works
have you tried to plug a monitor into the back of the laptop to make sure the back light hasn’t gone bad?
start the laptop without the battery. If this doesn’t work, i fear the internal power module is defective. This is mostly the reason if the monitor doesn’t switch on.
How old is the laptop? Based on my experience, notebooks/laptops start to have display problem as they ‘grow older’
Maybe the display cables are loosen or the LCD died. Try calling the BenQ support about this
