Hardware :: HP W2207 Randomly Going BLACK, Then Back To NORMAL?
Sep 24, 2009
So, i have this HP w2207 monitor that is amazing, but lately it has been randomly going black, then coming right back on as if nothing is wrong... its not trying to sleep or losing power because the indicator at the top is normal.
There is no regular interval, sometimes it will do it 2 or 3 times in a row, some days it won't do it at all.
Screen will go completely black for a second then back to normal display.Makes no difference what application I'm using. Within last 10 minutes went black for 4 times. Does not power down, just screen goes black.Contacted support via phone, they had me shut down, unplug power cord, then plug in and start. Appeared ok while I was on phone with support.Didn't use imac for 1 1/2 hours, now I notice it going black again.
my screen keeps going black randomly but everything in the background is still playing. When i press the power button twice it will go to standby and then turns on again, but the black screen keeps getting more and more frequent. Ive tried resetting the SMC and the command+option + PR thing but nothing has worked.
My MBP has all the sudden started to throw a black screen at me. i have to restart my MBP every time this happens. I have tried doing a fresh install and starting fresh and this doesn't help, I've even installed every app one at a time and tried to figure it out.
Info:MacBook Pro (13-inch Early 2011), Mac OS X (10.7.3)
This is the problem I just bought a brand new 2009 iMac with 4 Gigs of RAM. I installed the iStat Pro app that shows whats running and how much things are going on. I noticed that the RAM indicator went from 4 GIGS of RAM to 940MB of RAM. I'm freaking out b/c this a brand new computer. Is there a solution to bring the RAM back to normal?
My Macbook pro running Tiger 10.4.11 is now starting to randomly, what seems like shut the screen down, and just go to a black screen.
I am running my macbook pro, plugged into the AC / Mains, with another monitor connected, when the macbookpro screen goes black the dual monitor stays up and running, I can even do the mirror screen from the actual macbook pro and run it on the dual monitor and its running perfectly (I hope this makes sense!).
Its really odd and only started in the last few days.. it lasts about 30seconds at a time and is starting to worry me!
It started almost 3 days ago. My 2008 macbook screen would suddenly turn black. When watching a YouTube video, the sound still plays but the screen is black. I tried adjusting the brightness, didnt work. I tried pressing the power button but nothing changed. Then when i closed my screen and opened it, the display would return with the (turnoff, sleep etc) question meaning my button computed something.
My Imac---which is less than a year old--randomly goes black but continues to function otherwise. This is happening on a more and more frequent basis.Â
I installed Cleardock [makes the dock transparent] and I tried getting rid of it by going into user/library/preferences and deleting com.apple.dock.plist. However now my dock is still clear but also reflective [see pic]. So then I tried to reinstall cleardock then uninstall it but that didn't work [I did a killall Dock to reset it]. I also read on a forum how to restore my dock to the default but that just gave me back the default application icons. So how can I get my dock back to normal! And if it helps I have time machine back ups from before my dock was like this.
The printer prints copies in a very light grey colour. I would like it to give a normal black print. It is the driver. If so where do I get an update for the driver. Or what else can it be.
This is my first Mac so it's pretty much foreign to me. I was holding down control and accidently used two fingers to zoom on my track pad, and it zoomed in on my entire screen. How do I zoom out and get my screen back to normal?
Upon start up my screen goes to normal gray w/apple logo and spinner then goes black. Cursor is visible and still is moveable but nothing else. I safe booted and bar came up also but then back to black screen.Â
Anyone else noticing their new macbook air freezing randomly and the screen just turns completely black? The back light is still on but nothing is on the screen.
None of the buttons work, can't force quit anything, i have to hold power button to turn it off then back on. It has happened to me twice already, first time when i was installing the adobe suite, second time is when I was working on a school assignment with a simulation app (not cpu or memory intensive AT ALL).
My laptop screen randomly going black during the use of computer, but the cursor is active and it moves with the track-pad. I bought this macbook pro 15"Inch laptop just 3 weeks ago. Is there any alternative for this issue?
My mid 2013 MBP, 2.8 GHz Intel Core i7 with 16Gb 1600 Mhz DDR with a 500 GB SSD running Mavericks 10.9.3 has, since upgrade to Mavericks, developed a tick. It will occasionally and erratically (some days nothing, sometimes once a day, sometimes twice or more) go black with cursor arrow visible and responsive. (Responsive=it's visible and moves as expected in response to trackpad) The screen comes back after 30-40 seconds or so, but not in response to any keypress or mouse movement that I can detect a pattern for. It just sits there, while I hit escape, spacebar, shift, cmd-option-esc, cmd-option-tab, mouse around, whatever, then comes back. System is fine, don't even get the beach ball. So it's a minor annoyance, except when I'm presenting to a roomful of people who are waiting for my machine to wake up, and that 30 seconds can be FOREVER. Which has happened twice now. When I'm connected to an external screen via thunderbolt that screen is black as well.Â
tried the fix of resetting SMC as well as Safe Mode boot to complete any unfinished OS updates. But the symptom is different, and those fixes haven't worked. I've never had a bad reboot, this condition just seems to pop up without apparent rhyme or reason. It's so infrequent and unpredictable that I despair how long it will take me to run bare and cycle through restoring background apps.
How Do I get the mac minis dock and text size back to normal. I used it this afternoon and now tonight the size is huge and I nor the person who used it after me says he changed the size. I hate this jumbo sized text. I want the default size back.
Right now my MBP is setting idle (except for this process of course) and the fans are screaming at 5607RPM. I'm having this happen more and more lately. Anyone have an idea of what is causing it?
Attached is a screen shot that shows what is running. NETserver is using almost 70%. Why? It usually takes a reboot to get the fans back to normal.
This started very suddenly today. I was in finder looking through some pictures when my screen suddenly turned blue. After a second, it faded back to normally, so I continued what I was doing. After about 5 minutes, it happened again, but faded back. It's be less than a half-hour, I haven't touched the computer but the screen is turning blue than fading back every half a minute or so. Every now and then, the screen stays blue for about 20 seconds.
I keep having the screen turn blue and then suddenly go back to normal. It's a quick flash, totally random, repetitive during operation, no noises, and nothing else is interrupted. It does not restart, log off, or try to. Is it about to die?
My finder icon changed to a weird appearance. I didn't do anything for this. In other account its still normal, but I don't find any solution to put it back to normal.
I upgrade Mac OS 10.7.3. from a network with Lion Server in the office, using software update utility. I changed domain to access to upgrades and works fine. Now I am working our of the LAN, and every time request software update, show me a message saying "Cannot find nnnn.server.com", and can't make upgrades from apple's server. I changed domain, an clear lines, but message repeat. All the time search on software update server from office server. How can I change the software update server on Mac OS 10.7.3.
It keeps saying Ethernet cable is unplugged but it's not. And then it will turn back on and seem fine until it says unplugged again a few seconds later.I just installed OS lion and before I did ,this never happened.
Web pages randomly jump back a page or two for no reason. It sometimes happens when I'm not touching the trackpad or the magic mouse. I am using a MacBook Pro O SX Version 10.7.4. It happens with Safari, Firefox and Google Chrome.

I am having this weird problem. Suddenly my Trackpad refuses to accept all left clicks, also including the lower left real click. I can't do anything except booting into safe mode, then back to normal mode.
