Monitor turns off after boot? macmini

I have a strange display issue.
I am running a dual monitor setup on my 2010 mac mini. It used to work fine but now suddenly the monitor using the minidisplayport won't work right. It just stays turned off.
If I unplug the HDMI monitor and only use the minidisplayport, the connected monitor turns on while the computer boots (grey apple screen), but instead of eventually showing my desktop the monitor just turns off. The computer acts as if nothing is wrong. If i switch the monitor to the hdmi everything looks normal.
Resetting pram makes no difference.
Starting in safemode makes no difference. no picture.
Apple hardware test shows no issue. (The weird thing is, AHT has no problem keeping the minidisplayport -monitor running)

Only the Hdmi monitor shows in systems pref/displays. Ofcause i dont know if anything is going on on the black screen. There is no arrange displays option though.
I only have bad experience contacting apple, so that will be my last option. I have no apple store near by. The mini is still under waranty, but i also think/hope it is just a software issue.

Satellite M200 monitor turns Off after boot & battery won't charge

Hello, I'm from Jakarta, Indonesia
I have a problem with my Toshiba Satellite M200 Notebook (Running Windows 7 Home Premium)
after i press the power button to power up my notebook, It works fine showing BIOS and Windows Boot Screen,
but after that my monitor just suddenly turn off when Windows supposed to show login screen.
sometimes the monitor don't turn off, but shows lower resolution (i don't know exactly what resolution, maybe 1024x768 or 800x600, i'm using 1280x800)
so the only thing i can do is press the power button again to shutdown improperly then press the power again to power up, my monitor works normally
try to shutdown then power up again in couple hours later, the problems comes again.
from the moment i install Windows 7, i use 8.15.10.1930 driver version (downloaded from Intel Download Center, which included Intel TV Wizard)
2 days ago my friend said that i should install the driver from Toshiba's support site, so i went to csd.toshiba.com and download the 8.15.10.1825 version from that site (which not included Intel TV Wizard )
my monitor works normally after I installed the driver i've got from csd.toshiba.com, so i think that the problem because Intel TV Wizard somehow messed up with my notebook. But this morning this problem comes again, my monitor just turns off suddenly ..
besides this problem my battery seems like failed to recharge, Windows shows my battery has fully charged, but when i plugged out my AC adapter,
it just remains for 15-20 minutes before my notebook shut down automatically
three months ago i just brought my notebook to local Toshiba Service Center and bought new motherboard to replace my old mobo (which have a VGA issue too!)
there's something i can do (related to Windows or software/driver) or i have to bring my notebook to the service center again?
are they somehow make a wrong wiring when replacing my motherboard?
and am i have to replace my battery pack too?
i've been using this notebook for about a year and half and there's nothing wrong with my battery before replacing the motherboard
any help would be appreciated :D

well, i can't find my model's driver in Toshiba Europe site,
in Satellite M series it only shows M100 and M70 and not including M200
i found http://pc.toshiba-asia.com which covering my region. after choosing my product they give me link to download Windows 7 driver, here's the link
http://support.toshiba-tie.co.jp/windows7/download/Satellite_M200_32_sp.htm
Windows7 Driver | Intel Display Driver | 8.15.10.1825
they have the same driver version (and same size too) with my current driver i've got from csd.toshiba.com
any other ideas besides the driver issue ?

MY MONITOR TURNS OFF AFTER 2 MIN OR SO HP TOUCHSMART 300-1330

MOVING THE MOUSE I GET TO THE LOG IN SCREEN,SCREEN SAVER IS TURNED OFF AND SET TO HIGH PERFORMANCE ??

I would start by opening the power options, selecting change plan setting, and then select change advanced power settings. There are a lot of setting that can be managed from this location. I hope this will work for you.

Monitor turns off at high resolution

Hi there,
I attached an external monitor via displayport to my lenovo x230 (Intel HD4000).
If I set the resolution to be 1920x1080 (or lower) everything runs fine. If I switch to the monitors native resolution (1920x1200) the monitor turns off after about 1 minute. The monitor tries to turn on again for two to three times, but only for few seconds.
If I dual boot to windows the monitor is running fine.
Any idea what might be the cause and how to fix it?
Thanks a lot

Config xorg, driver installed .... pick up the crystal ball and your answer in my thinkpad t430u (hd4000) with intel-dri, run perfect at 2560x.. or just the monitor is failing because raisins resolution supporting, i don't no. luck

Can not turn on the monitor on Satellite after dispaly turns off after 10min

Aspire One D255 monitor shuts off during boot

Every time I boot, immediately after the kernel lauches init, my screen powers off. About 15 seconds later, it comes back on.
The delay before coming back on seems to be independent of the init process. If I speed init up, by the time it comes back on it's waiting at the login prompt. If I slow it down, it comes back on while init is still running.
I tried adding an echo -e -n '\033[13]' to my init scripts in an effort to unblank the display, but it doesn't help.
This happens both booting of the install image and after installation. It makes it extremely hard to figure out what's going on during startup.
Has anyone seen this before?

I have a similar issue with my aspire one, but the display is not turning off, it is actually the backlight turning off during boot. I use fbsplash with a dark theme but a bright progress bar. During boot, it appears as if the screen has turned off, but looking closely, I can still see the progress bar.
I have tried several different methods of keeping the backlight on to no avail.
Personally I am thinking it is monitor signal detection during a monitor mode reset during boot, ie from console resolution switching to KMS resolution. Most monitors lose signal detection when changing mode (in my experience). Some display a "No Signal" message of some sort, some briefly turn off until signal is detected again, and in the Aspire One case, the backlight turns off. Put it down to monitor manufacturers built in power saving "features".
Tha same thing happens when I boot windows.
Of course, if anyone does come up with a solution, I am eagerly listening!
Cheers.

Have my MacBook Pro plugged into a monitor and also using a wireless keyboard. I want to close the macBook but every time I do the monitor turns off - is there a way to avoid this?

Press any key on the wireless keyboard after you close the MBP and it goes to sleep. The computer will wake up with the external monitor as its display. This is called Clamshell mode.

Hp zr2740w turns off after few seconds

I have the same problem as described in an earlier post:
http://h30434.www3.hp.com/t5/Desktop-Audio-Video-Monitors/hp-zr2740w-turns-off-after-few-seconds/m-p...
My HP zr2740w turns off after a second or so. Tested with vga/dvi/displayport and desktop pc/laptop, so it's not a cable issue.
My hp zr2740w was bought in July 2012 so it's probably out of warranty. I live in Finland. The webshop I ordered the hp zr2740w does not exist anymore. The HP support pages don't seem to have any support numbers for displays.
I took the display to a local IT support / electrician guy and he said it's a power supply issue. But he couldn't find a place to order the part so he could replace it.
Hopefully I'll get some answer here or an idea what to do. Wouldn't want to throw away an expensive display just because it has power issues.

Laptop turns off after 3-4 seconds

Hi there, My Laptop turns off after 3-4 seconds of turning in on. When the battery is plugged in or mains lead, the on /off switch does absolutley nothing. When you open the lid however, it turns the laptop on for 3-4 seconds then cuts out. After taking the laptop appart, i have found that the only way to get the laptop to turn on properly is to take out the power switch chip unit strip cable, insert it so it turns on and then remove it quickly. this way the laptoip stays on. if you insert the power unit strip cable, it turns on fine, but if you leave it in, the laptop turns its self off after 3-4 seconds ( as if the power button was held down) Do you think this is a problem with the either, the power button chip unit, the main board, or maybe even the magnet switch in the lid!? i have upodated bios/cleared CMOS, ran all diagnostics, tried everyt combionation of resetting, e.g. hd/ram/cables /power button down for a minute, bat back in power lead back in...etc, everything installed fine and came back 100% ok as if there is no problem, but the power switch is doing nothing!. Please help or let me know if anyone else had this issue, i really need my laptop working. Kind Regards, James Hardy

Does it do it booting in these two modes?
Safe Boot from the HD, (holding Shift key down at bootup).
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Monitor turns off to sleep but computer stays on???

Monitor turns off to sleep but computer stays on???
Any clues why? I can only shut-down and it gets annoying because I like to be working in less than a minute after powering up. Any things to look for to help?

Thanks,
don't know why it'd matter if I had a warranty or not since the function
in question is apart of what I'm supposed to be getting w/ cost of computer.
Time to load the overpriced 1 ton computer into the car and demand they fix it at the apple store. This is absurd since I originally bought this computer for music creating and it's the most unreliable computer EVER as far as stability for music. My audiophile records for like 10 sec. before the sound cuts out, everytime, but of course that's not apple's fault.
Never buying apple again. This is straw that broke the camels back. Anyone wanna trade a pc for my G5?
Sorry for the venting but this is where I draw the line!
Thanks,
Henry

[SOLVED] USB Harddrive via fstab turned off during Boot - Error

Hello^^
I'm trying to mount my external USB Drive.
I put the following line in fstab:
/dev/sdb1 /media/Musik ext4 noauto,user,default 0 1
I only want to start the Harddive occasionally.
The problem is, when the drive is completly turned off during boot I get the following error:
No such file or directory while trying to open /dev/sdb1
Possibly non existend device?
I thought that the noauto Option should prevent fstab from mounting the hdd???
regards

PS: Manual mounting works without any problems...

Let me give you a hand then. The following I have in my /etc/udev/rules.d/11-media-by-label-auto-mount.rules, and what it does is:
-- pick the name of a drive,
-- create a dedicated /media/mountpoint name (certainly, "mountpoint" is replaced by the name of your drive),
-- mount the drive on boot,
-- unmount the drive on shutdown and delete the /media/mountpoint.
KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"
# Import FS infos
IMPORT{program}="/sbin/blkid -o udev -p %N"
# Get a label if present, otherwise specify one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"
# Global mount options
ACTION=="add", ENV{mount_options}="relatime"
# Filesystem-specific mount options
ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},utf8,gid=100,umask=002"
# Mount the device
ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%k /media/%E{dir_name}"
# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media/%E{dir_name}"
# Exit
LABEL="media_by_label_auto_mount_end"
Plenty of handy examples you can find in /lib/udev/rules.d/ and modify them so they meet you needs. I hope it clarifies the matter a bit.

Yoga display turns off after 1 minute

I'm having an annoying problem with my new Yoga related to the display and have not seen any other posts with a similar complaint so perhaps this is a simple fix that I'm just not able to sort out on my own. My display turns off after 1 minute of inactivity. The only means for changing behavior like this that I am aware of is through the Control Panel Power Options. My settings for "turn off the display" are 10 minutes on battery and Never while plugged in (note screen shot attached). Regardless of my settings, the screen turns off after 1 minute. I've changed the settings to multiple configurations and restarted with no change in behavior. Perhaps there's some other settings area, maybe something specific to Lenovo that I'm not aware of (since this is my first Lenovo laptop). Anyone with similar problems or insight?

This may be a Windows 8 issue. I finally fixed this problem by identifying the screen saver as the issue (and I wasn't using a screen saver). Type "lock the computer" into the search box after clicking the search charm, which brings up the screen saver dialog box. Mine was set to 1 minute, though I'd never set it myself. If you can't change it, choose a screen saver and you should be able to do so (and can then switch back to no screen saver). BUT, here's the problem. Other things you install (or settings within things you install) can apparently change and override whatever you type in for the delay time. Try applying your new time and exiting from the dialog box, then open it back up again. I was finding that it kept going back to 1 minute. To reset things so that you can get control again, type "user accounts" into the search box and when the dialog box comes up, choose "Reset Security Policies". Then you can go back to the screen saver dialog and successfully change the delay time. See http://social.technet.microsoft.com/Forums/windows/en-us/ace4085a-b0ba-4a98-898d-cd92d9e88e13/window... for some detail.
