fixed : Benq monitor stays black when MacBook is switched on

Question :

I have a Benq BL2420PT external monitor as a desktop screen connected to my MacBook using a Displayport-cable (actually a miniDisplayport-to-Displayport-cable). When my MacBook goes into sleep mode or the Ben monitor goes into sleep mode itself the screen goes black. But when I try to revive the monitor by moving my external mouse or pressing any key on my (external) keyboard, the MacBook starts up, but the Ben monitor’s screen stays black.

This same thing sometimes happens when I startup my MacBook and close the lid before the Benq monitor switches on.

What can I do to fix this ?

 

Answer :

The following trick might help for other Benq monitors, and maybe even for different brands of monitors also. This works for the Benq BL2420PT monitor if the screen stays black even when the connected Mac is turned on :

  • on the frame of the screen, bottom right, you see 5 indicator lights, next to the Power-indicator ; these are all touch-buttons
  • if the Power-indicator/button is steadily glowing in white, don’t touch it ; only if it has another color, touch it to switch on the monitor
  • if the Power-indicator still doesn’t glow white, check if all cables are connected properly and make sure the physical ON/OFF-switch on the bottom of the screen is switched ON
  • touch the one indicator light/button that is nearest to the centre of the screen (so the most left one)
  • if a message appears “No cable connected”, just wait
  • if a menu appears with 5 cable connectors to choose from, don’t touch anything, just wait
  • just wait (usually up to 30 seconds, sometimes even a minute) and the screen will switch on

NOTE : the most important thing is that you DO NOT (neither accidentally nor intentionally) touch any other indicator/button ! as this usually screws up the monitor’s software setting that corresponds to the physical cable connection (to correct that, you should toggle around with the these touch-buttons until the menu with the 5 cable connectors reappears and you can then choose the one that corresponds to your physically connected cable)

If the above doesn’t work, look here for alternate procedures to revive your black screen :

fixed : wake MacBook from deep sleep

Question :

Whenever I think I am only closing the lid on my MacBook for a few minutes, but get distracted and end up not turning back to it for about an hour, my MacBook seems to have fallen into deep sleep. Then nothing seems to help to get it ‘back to life’, and even though the battery is still indicating about ‘half full’, the usual click on the SPACE-bar doesn’t help, and neither does typing any key or key-combo on the keyboard…

My MacBook’s sleep is actually so deep my wife calls it ‘hibernation’, and my children call it ‘zombie Mac’…

So I always end up either taking out the battery to completely restart my MacBook or keeping the power-button pressed until it finally restarts…

Isn’t there any other way to wake my MacBook from deep sleep ?

Answer :

Yes, there is.

The solution you have been so near to the simplest solution, but you didn’t recognize it…

Instead of keeping the power-button pressed, you should just press the power-button for one quick second

…that’s is. Then your MacBook will slowly wake from deep sleep… it will first show a faded white-ish screen with a progress bar… and if that’s finished loading, your MacBook (Pro) will be right back were you left off…
