Laptop starting up issue

[Ellxz]

My laptop does start up but the screen does not light up at all. This happened not long after a windows update, the LED light lights up and does not flash. Ive tried the key 'hacks' the bot provided but non of them are working. What do i do?

Here's what you need to do, to identify the issue and resolve it accordingly:

• check if it works fine on an alternate/external monitor.
  • If it works fine on an alternate screen, please Perform a hard reset, Attempt a BIOS recovery  and then, Run the System Diagnostics tests.
