fixed : black screen and no BIOS Boot Menu on MSI NightBlade X2B gaming-PC

Question :
I have a MSI NightBlade X2B gaming-PC that I need to reinstall Windows on, the internal HD has been reformatted externally, but when I try to startup the PC, the HDMI-connected monitor gives only a black screen with and error message saying something like “no HDMI signal detected”… I need to get into the BIOS Boot Menu to fix this, but how do I do that If I cannot see anything on screen ?

What can I do to fix this ?

Answer :
The MSI NightBlade X2B gaming PC not only has an internal HD (usually 1TB), but also a 500GB SSD that is hard to access manually. And Windows has usually been installed on that SSD, not on the HD.
If the PC starts up porperly (lights and sound of running fans), then the fix to getting into the BIOS Boot Menu is to reset the CMOS Battery. To do that, you need to do this :
– diconnect al cables from the PC (Power, HDMI, USB, etc.)
– open the PC housing (slide open the red protectors on the back and unscrew the screws)
– take off the side panel
– if you are in an environment with high static electricity you need to unplug the internal cables from the graphics card, the HD and the power (but usually you’ll be okay if you are in a clean and smooth environment, especially if continuously connect yourself with al metal wire to a grounded large metal object or a radiator)
– unscrew the graphics card, which is the bottom mother/daughter-board (first unscrew the L-shaped black plate on the backside, then tilt out the graphics card starting at the back)
– behind the graphics card, on bottom left of the motherboard, you will find the red&black (or red&white) cable that connects the CMOS Battery to the motherboard
– gently unplug the white connector that has written “BAT 1” under it
– then leave tthe PC like this for about 8 hours (so a working day or a night), this will drain the motherboard and all internal electronics so they will automatically reset to factory settings (except for the HD and the SSD, so you will have to wipe or reformat those later)
– after this cool-down period, reconnect the small white connector and reassemble the PC (starting with the graphics card)
– then, reconnect a USB-mouse, a keyboard (seems like a PS/2 keyboard works better at this stage, but a USB keyboard should also work), a UTP/Ethernet-cable (if you have wired Ethernet available this will work easier then WiFi at this stage) and the HDMI-cable to your monitor
– then, startup the PC using the Power Button and immediately start pressing the F11 key on your keyboard repeatingly (the F11 key is the ususal key to press for MSI motherboards, but you might need to press the F1, F2 or F12 key)
– the PC should now start up in BIOS Mode, but if it does not, shut down the PC and restart it using the Power Button and immediately press the CTRL + ALT + DEL key-combo on your keyboard, which should get you into BIOS Mode

Then proceed as usual for reinstalling Windows 10 (or 11) and don’t forget to format the HD to NTFS and wipe unwanted and/or unneeded old user data to free up space on the SSD (it’s easiest to do so after installing Windows).

That’s it !

fixed : screen and Touch Bar stay black when starting up MacBook Pro

Posted on by

Question :
I was trying to start up my MacBook Pro this morning but when I did, nothing appeared on screen… the screen stayed black… even the Touch Bar above the keyboard stayed black… I think I could hear a distant startup chime sound, but that was all… no indication of any response to my start-up attempts…
I thought that the battery might be empty, so I plugged in the USB-C power cable (which unfortunately does not turn on any light that indicates it’s charging), but the result of my start-up attempts stayed the same : black screen, black Touch Bar and only a dim, distant start-up chime…
Is this some kind of hardware failure (broken screen) ? Or is this a software problem that I can fix myself ?

What can I do ?

Answer :
This is a software problem.
You can fix this by doing the following :
– simultaniously press this key combo on your MacBook Pro’s keyboard :
[CTRL] + [CMD] + [ON/OFF] for at least 5 seconds, then release

[CTRL] = the ‘Control’ key
[CMD] = the ‘Command’ key, the key with the stylized 4-leaf-clover, previously known as ‘Apple’ key
[ON/OFF] = the ‘Touch ID’ key on the far right of the Touch Bar that is used for starting up, shutting down, and Touch ID

…and now, your MacBook Pro should start-up as usual, starting with a white Apple logo appearing on your black screen…
if it still doesn’t work, use this slightly longer procedure :
– press the [ON/OFF] key for at least 10 seconds to shut down your MacBook Pro
– then press the [CTRL] + [CMD] + [ON/OFF] key combo for at least 5 seconds to start-up

…That’s it !

fixed : β€œiPad could not be activated” error on old iPad with empty SIM-slot (or iPad showing β€œblack screen with time only” error)

Question :

I have an old iPad that I want to give to my children, but when I switch it on, there’s only a black screen showing the current time (not sure if it’s actually the correct time).

I left the iPad alone for some time, and when I switched it on again, I get an “iPad could not be activated” error.

Now, whenever I switch on the iPad, I either get the “iPad could not be activated” error or I get the black screen displaying the time only… I can’t figure out a way to get anything els from it…

What can I do ?

 

Answer :

For some unknown reason this problem appears on old iPads with an empty SIM-card slot. To get your iPad working again, follow these steps :

  • make sure the iPad is charged at least 20%
  • take the SIM card tray (holder) out of the iPad
  • vacuum the SIM card slot using a vacuum cleaner
  • if you have one, put a SIM-card in the tray (even if it’s an old inactive SIM-card), if not leave the tray empty
  • put the SIM card tray back into the iPad
  • reset the iPad by pressing the Home-button and the ON/OFF-switch at the same time
  • press both buttons until the white Apple-logo appears
  • then release the ON/OFF-button, but keep pressing the Home-button
  • when you keep the Home-button pressed long enough, you will get a β€œconnect to iTunes” message
  • when an error message (or anything else) appears, repeat the reset
  • plug your iPad’s USB-cable into a Mac (or PC) that has iTunes on it
    • a newer Mac with Apple Music app might also work, but iTunes will probably work easier since this is an old iPad…
    • if you don’t have a Mac, you can probably use a PC with iTunes for Windows also (this wasn’t tested though…)
  • in iTunes you will get a message that the software on the iPad needs to be updated, click OK to go ahead
  • make sure your Mac (or PC) is connected to the internet, so it can download the update
  • this will take quite a long timeΒ 
  • you will only see an β€œiPad recovery mode” screen in iTunes, with no indication of progress
  • on your iPad you will see the Apple logo and an empty progress bar
  • if you do not touch anything long enough, the progress bar will suddenly start moving after 10 or 15 minutes (maybe longer)
  • wait for the progress bar to complete and disappearΒ 
  • then you will get an β€œentry code protection” error in iTunes
  • open your iPad with the screen unlock code
  • on the bottom of the β€œChoose a Wi-Fi Network” page that automatically opens, you will now see a β€œconnect to iTunes” option, select that
  • if your iPad is recognized correctly now, you’re okay
  • else, redo the entire procedure and choose β€œErase” instead of β€œRepair” (β€œRecover”)
    • note : if you need to choose β€œErase” you will loose all content that was on the iPad (the only way to get your content back after that is to import it from your iCloud backup or iTunes backup – if you ever made one manually or automatically)
  • follow the instructions and you will also be guided through instructions import a backup (if you have made any previously)

That’s it !

fixed : Benq monitor stays black when MacBook is switched on

Posted on by

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 NOTΒ (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 : MacBook’s external monitor screen stays black

Posted on by
29

Question :

In my office, I am using an external monitor as my main screen for my MacBook Pro.Β Today, the screen didn’t respond when I connected my MacBook however :Β the screen stays black and nothing appears on-screen.Β So I opened up my MacBook and used the built-in screen to figure out what’s wrong, but so far I haven’tΒ found any indication in the DisplaysΒ Preference Panel that my MacBook even detects the second screen…

What can I do ?

 

Answer :

In such situations you should always do this first :

Remedy #1 :

  • if you are using a MacBook, MacBook Air or MacBook Pro, make sure you have the power adapter connected
  • if your laptop is on battery power, the external screen will go black whenever you close the lid of your laptop (when on battery power, all connections are powered off when you close the lid to save energy)

if this works, you’re good, if not, try Remedy #2

Remedy #2 :

  • make sure your monitor is switched ON
  • then hit the SPACE-bar on your external keyboard several times (maybe once, usually about 5 to 10 times…)
  • the monitor should now appear and show the inlog panel to unlock your screensaver
  • then login

if this works, you’re good, if not, try Remedy #3

NOTE : if you have a Benq monitor (especially the BL2420TP), try this first :

fixed : Benq monitor stays black when MacBook is switched on

Remedy #3 :

  • unplug all cables between the monitor and your Mac ( DisplayPort / Thunderbolt / HDMI / DVI / VGA Β and also USB, UTP, FireWire and PowerAdapter )
  • shut down your monitor
  • shut downΒ your MacBook
  • reconnect all cables and double-check if they’re properly connected on both the Mac and the monitor
  • switch on your MacBook
  • switch on your monitor

if this works, you’re good, if not, try Remedy #4

Remedy #4 :

  • on your MacBook, open Apple [main menu bar top-left] –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is no “Gather Windows” button, press the ALT-key on your keyboard and a button marked “Detect Displays” appears ; click on it when it appears

if this works, you’re good, if not, try Remedy #5

Remedy #5 :

  • on your MacBook, open Apple [main menu bar top-left] –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is aΒ “Gather Windows” button, click on it
  • then you will see 2 Display Preference windows on your MacBook screen
  • select the Display Preference window that has 3 tabs on it marked “Display”, “Arrangement” and “Color” (not the windowΒ that has “Display” and “Color” only)
  • first, press the ALT-key on your keyboard and a button marked “Detect Displays” appearsΒ where the “Gather Windows”-button used to be ; click on it when it appears
  • if your monitor switches on, you’re good, if not…
  • click on the “Arrangement”-tab and in the next window put a checkmark at “Mirror Display”
  • if your monitor switches on now, uncheck the “Mirror Display” option again and close your MacBook… you should be good now…

if this didn’t work, try Remedy #6

Remedy #6 :

  • unplug all cables between the monitor and your Mac ( DisplayPort / Thunderbolt / HDMI / DVI / VGA Β and also USB, UTP, FireWire and PowerAdapter )
  • shut down your monitor
  • shut downΒ your MacBook
  • reconnect your Mac to your monitor using a different type of cable then you normally would choose (e.g. if you normally use a DisplayPort/Thunderbolt-cable, use an HDMI or DVI cable now)
  • switch on your MacBook
  • switch on your monitor
  • if your monitor wakes from sleep now, open Apple –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there isΒ aΒ “Gather Windows” button, click on it
  • then you will see 2 Display Preference windows on your MacBook screen
  • now, remove the monitor-cable that you have just used to connect your MacBook to your monitor
  • then, reconnect your MacBook to your monitor using all cables you normally use to connect the two
  • if your monitor now wakes from sleep, you’re good
  • if it doesn’t, restart your monitor
  • it that doesn’t help, restart your Mac

normally your issue should be resolved by now…

if still the monitor stays showing a back screen, I’m sorry to inform you that your screen probably has a hardware problem… if so, get an authorized Mac-repair-centre to fix it, get the Apple Store support-crew to fix this…

that’s it !

fixed : black screen when trying to take a photo in iOS

Posted on by
Reply

Question :

Lately, whenever I try to take a photo with my iPhone, all I get is a black screen.

I am using the pre-installed Camera-app in iOS.

How can I get this fixed ?

 

Answer :

There are two known software causes for this ‘black screen’-issue (so apart from hardware problems like broken iPhones) :

solutionΒ Β #1 :

If you have just used your camera in another app (e.g. WhatsApp) and you then switched to the Β standard iOS Camera.app, you might run into a black screen because the camera is still being claimed by the previous app…

The fix for this is easy : close down the iOS Camera.app and the other app that was using your camera, thenΒ re-open the iOS Camera.app ; to do so :

  1. double-clicking on the Menu-button below the screen (in the next view you’ll be able to browse through windows of all open apps)
  2. close all apps that are using your iPhone’s camera (by swiping the windows of those apps you want to close upward)
  3. then return to normal view by clicking the Menu-button once
  4. and when done, re-open the iOS Camera-app

solution #2 :

The black screen issue in Camera.app has been reported as a bug in earlier versions of iOS 9, so fixing it is simply done by updating your iPhone to the latest version of iOS 9 (or iOS 10).

To do so :

  1. on your iPhone, go to Settings –> General –> Software Update
  2. you will most likely see that you don’t have the latest version of iOS
  3. activate the update to the latest version of iOS

…that’s it πŸ˜‰
