MacBook Pro :: Why Won't It Startup Properly Without External Monitor And Keyboard
Mar 14, 2012
If I connect a external monitor and keyboard to my late 2011 Macbook Pro (running Lion) it starts up just fine. But if I try to start it up without these (or any other devices) attached, I get no display on the internal screen and the internal keyboard is ignored (the caps lock light doesn't light up when the key is pressed). However, I don't think it's a hardware issue, as a PRAM reset seems to work (I get the second chime) indicating that the keyboard is OK. And I get a second or so of grey screen before the screen goes black. I've tried resetting my SMC and my PRAM. The latter seemed to fix the problem once - but then it came back, and won't go away again this time. I've also tried starting in safe, single user, and verbose mode, but none of these seem to make any difference. I've been having some issues installing Windows (under both BootCamp and Parallels) but wouldn't have thought that these were related.

I used to have a mac Mini that connected so effortlessly to the monitor and allowed the full resolution (1920x1080). But I'm trying to do that with my MacBook (as I recently sold my Mini) and I'm unable to get it to do what I want to. I have Snow Leopard. It would not allow me to do anything until I updated the OS. The monitor was not recognized at all. Except I noticed when I plugged it in, the macbook screen would flash...so I figure it's recognizing something. But in display settings, detect display wouldn't show anything, neither would restarting. That is, until I updated Snow Leopard.... Anyone know why this might be? And now that I've been able to get something on the display, I'm still not at all satisfied. The resolution is terrible. It will not allow me to choose anything other than the resolution on my macbook screen, but over 23" it just looks terrible. Not only that, but the Macbook screen stays on. I want the mb screen to go off, and full resolution be on the external monitor. I can choose another option for an extended desktop but that's just ridiculous. I have no desire for anything like that.

Have a brand new MBP 13" using Thunderbolt-DVI adapter with my old Dell 2405 LCD. Have an interesting scenario ... when the display goes to "sleep" there is still some type of signal coming out of the display port. The monitor will stay on and just blink "NO SIGNAL DETECTED ON INPUT 2". But the monitor actually still stays on.When I put the entire laptop to sleep them the monitor will properly power down to sleep mode.
I don't think its the monitor because I've used this monitor with a number of different machines and graphics cards, in every scenario when I had the display set to sleep it powered off just fine.

Recently I installed the Snow Leopard OS on my Macbook Pro, previously I had 10.5 installed. However, now when I connect my Macbook to my flatscreen TV (Panasonic Plasma), using a mini display port cable to an HDMI cable, there's a black border around the edges of the picture. Before the Snow Leopard upgrade I was able to view the entire screen area of the Plasma TV, without any borders. The only thing I've done differently since then is install Snow Leopard. Does anyone know how I can fill the screen with image without using the zoom option on the TV screen, as the zoom cuts off some image at the top and bottom?

I want to buy a 19inch monitor for my desk because I am going to start coding and the display on my Mac is too small and I want something a little bigger.
What I want to do is connect my macbook to the external monitor with my wireless keyboard and mouse connected to the mac and then close the lid and the display is on the external monitor. So in other words, my macbook is becoming a Mac mini.

During start up I get the apple logo and everything boots although it takes forever, the apple logo goes away screen goes blue, and sometimes it loads to the login screen about 10 mins later, and sometimes it just sits there. - During restart, it shuts down makes all the appropriate sounds, screen goes dark, and all you hear is a residual humming from the inside under the keyboard, and then never restarts. (You have to force shutdown) - Same story as above with both shutdown, and sleep.
The only way to get it to load successfully is in safe mode, but even then it still wont do the above problem correctly, it just at least starts.
- Resetting the PRAM, Holding power button for 5 seconds until repeating flashes, I've tried reinstalling snow leopard 5 times, I've checked for updates, I've repaired disk permissions, I've repaired the disk, I've even tried stepping the OSX back down to 10.3(The original operating software for this MB)

I usually use my 2209WA connected to my Desktop running Windows 7, but sometimes I'll connect it to my MBP. Windows seems to have found a color profile that works very well, which it got from Windows Update, created by Dell, presumably.It might not be good enough for someone who needs 100% accurate color, but it's good enough for me.
I tried two different profiles for this monitor connected to my MBP. The first was one I downloaded from a forum somewhere, and the second was the one Windows is using, copied over. The display looks OK with both, but the color depth isn't nearly as good as it is on Windows. Connected to my MBP, the colors look washed out and flat, while the same colors are much richer when the monitor is connected to my PC. For example, pure blue (#0000FF) looks faded when the monitor is on my MBP, and much deeper when it is on my PC. I tried changing the gamma setting under OS X (manual calibration), but it didn't have much effect. It is set at 2.2 for both 2209 profiles and for my MBP LCD's profile.
How can I make my monitor properly calibrated when it is hooked up to my Mac?
In both cases I am connecting the monitor with DVI (just moving the cable since I'm too cheap to buy a switch), and both OSes have it set at native resolution. The settings on the monitor (color, brightness, contrast, etc) do not change when I switch computers.

I updated to 10.6.4 the other day on my mbp 17" 2.93 mid 2009 model the other day. Since, my computer has developed two problems. first and most annoying, the keyboard doesn't work properly anymore. Shift keys don't work, then they do work. One side doesn't then the other side does. option and command do the same thing. Is this a documented problem? I searched and saw it was prior to 10.6.4, but I never had any problems until this update. Also, when I shut my computer, instead of going to sleep now. It goes crazy, fans jack up to full speed and it gets super hot. Doesn't sleep at all. Funny enough before the update, when i closed the lid the computer would go to sleep and wouldn't wake up.

I've been using a Moshi ClearGuard KB protector for a while but haven't been happy with the fact that it gets cloudy over time and requires frequent cleaning to restore. I bought the Marware keyboard protector shown here because it looks nice and shouldn't have the same issue with clouding. My only issue with it is that it doesn't fit properly over the enter and shift keys, so the wording on the protector itself is not lined up with the wording on the key below. Does anyone else own this protector? Does yours have the same issue? I'm trying to figure out whether mine is defective or if it's a design flaw.

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.
When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.
My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?

I have a 22" Dell external monitor on my MBP. I know that I just close the cover to my MBP to shut off the screen. What do I do in those instances that I want to use both screens? There has to be something simpler than restarting the MBP?

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.
Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.

I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.

I have a second monitor (Dell 20 inch widescreen) hooked up to my 24 inch iMac, and while I'm running windows, when the iMac monitor sleeps, it sleeps. But, in Leopard (v10.5.7) whenever the iMac monitor sleeps, the secondary monitor does what a monitor usually does when the video cable is unplugged (does the whole factory test thing with the box of red/green/blue randomly moving around.) Is there any way to make it sleep?

I've had a 500GB WD My Passport for about 2 months now. It was working perfectly, until last week when it didn't want to connect properly (i.e. I would connect it 10 times, and about 6 of the times it would work). Now, it doesn't seem to connect at all. I can feel the HDD vibrating inside, so it is getting power, but it's not showing at all. What's very weird is that it doesn't even show on Disk Utility. I'm completely lost as to what I should do. I need to either get it to work again or reformat it somehow, because I'm going on a trip next week and need the space on it.

I just bought a Dell U2410 to use as an external monitor (connected with DVI) with my MBP. After initial problems getting the best calibration setup I'm now very happy with it except for one annoyance. The problem: When the MBP puts its display to sleep the Dell monitor goes into sleep mode and then immediately wakes up and then goes back into sleep mode, cycling like this indefinitely.

So my friend was using his MacBook and went to do something else. He came back and the screen was black, he hit space and nothing, tried the trackpad and nothing. He restarted by holding the Power button, and it go to the log-in screen, but he can't type anything, or use the trackpad. He has tired restarting several times and no luck. He also tried an external Keyboard/Mouse and that didn't work.
He did plug in a Flash drive and the light turned on, so the USB ports are at least getting power, but nothing is working.

I have had my Mac Pro for a few years now, and I rewired the bluetooth module when I first got it. I then had Airport installed about 3 months ago, and had to rewire it again because the "geniuses" at Apple didn't know the wires were labeled incorrectly. I just moved my computer downstairs and my Apple Bluetooth keyboard is not working correctly. It lags, repeats letters, etc. Upstairs on one desk, it worked fine. Down here, on a different desk, It's acting up. My keyboard is on the left middle of the desk, and the computer is on the floor on the right side. Total distance is less than three feet, with a file drawer inbetween. It works if I put it in my lap, but not on the desk. I just opened it up to check the wires again, and they are tight, and right.

I have a G4 powerbook with an LCD that only displays the top 25% of the screen. I've been using an external monitor with it just fine. Today, I reinstalled the OS and ran into a problem. The main OSX startup menu (you know, where it asks for your location, timezone, personal info, etc) is prompting me for information, and I can't see the forms to fill them in! The external monitor defaults to "extended" as opposed to "mirrored", and the forms are embedded, meaning I can't drag them over to my external monitor. Obviously, if I can't fill out these forms and get to the desktop, the laptop is completely useless.
Does anyone know how to force the external monitor to be "mirrored" from startup? Is there a keycommand?

I have been using the latest macbook pro 13.3" since April 2010. Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).
The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.
