MBP 15" 2.5Ghz display blink followed by system freeze

Lately my MBP sort of frozen with the blinking display, then it was unable to boot after I force shutdown the system, not even in the safe mode or the installation disk.
I have to run through the prcess of FSCK and resetting the PRAM before I can get it booting with the installation disk and run the Disk Utility to fix the permission.
I managed to get the system running again, and it went into the same problem I've mentioned above again and again...(I notice this only happen when I play the online flash game), eventhough I've fixed the permission everytime this problem occur.
Any tips on this issue? What has cause the disk error or the the permission error?
Thanks

You seem to have all of your ducks in a row. As far as your query in regards to HDD, I have four 750GB 7200RPM Seagate HDDs (ST9750420AS), one in my MBP, others for Time Machine and other backups. All are spinning. I suppose that is some kind of endorsement.
Ciao.

Could not find any data to display - how to modify system message

Hi,
We created an exception report in the Web Application Designer.
If there are no exceptions (so there is no data to display) the following standard system message is shown:
Could not find any data to display. This might be due to the current selection of variable or filter values
We would however like to modify/remove this message.
How can this be done?
Thanks
Dave

External display blinking on Macbook Pro Late 2008.

Hello,
Firstly, computer specs:
Macbook Pro, 15-inch, Late 2008
GPU: GeForce 9400M / 9600M GT
8 GB RAM
320 GB Hard Drive
On Mavericks v10.9.3
I want to connect my computer to my TV via a mini displayport to HDMI adapter, for gaming purposes. As such, I want to use the 9600M GT as my GPU. However, when I am in High Performance mode (which uses that GPU), the TV screen blinks on and off every couple of seconds. I have tried resetting my PRAM, which failed. I know it is not the adapter, because it functions when used on another laptop. I know it isn't my port because it works when in Battery Saving (using 9400M GPU). Can anyone help?
In short:
Late 2008 15-inch Macbook Pro, GeForce 9400M / 9600M GT
Mini displayport to HDMI functions when on Battery Saving (GPU = GeForce 9400M)
However, external display blinks on and off when on High Performance (GPU = GeForce 9600M GT)

Hi mjbecker2,
Welcome to Apple Support Communities!
The article linked below has some tips that may help you resolve the flickering issue that you are seeing on your TV.
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Cheers!

Trouble with MBP 15" and external display

ahh, the joy of a new display...
I just received my NEC 20wmgx2 (20" widescreen 1680x1050), a fantastic little monitor, with a little problem.
I cannot get this display to work properly with my macbook pro.
If I use DVI (DVI out to DVI in)
The external stays blank, and says no signal, the laptop display blinks, like it sees something is there, but even after clicking 'detect displays' nothing shows up.
If I use VGA (DVI->VGA adapter->VGA in)
Ok, now I have a picture, however the correct resolution is not on the list, all I have are typical non-widescreen resolutions.
Using third party software (switcresX) I am able to force the correct resolution option to get it to run at the right res.
However this is not an ideal solution by any means, and I would like to be able to run this monitor from dvi, no adapters, as I suspect that would be the best quality, and also avoid odd third party resolution hacks.
My question is then, does anyone have any idea why the macbook would not register the monitor correctly, or what I might try to do to get things on track?

I'm on looking for a solution, but I can only get my external Viewsonic working if I methodically unplug and replug in the monitor cord to the MBP 4-5 times. Try unplugging it (wait for the flash) and replugging it in (again - wait for the flash and a few more seconds for good luck) a few times.
I've been reading some posts about it not sending a signal to projectors and TVs properly. I think that may be it - it knows the external monitor is there, but isn't sending the external monitor enough signal to wake it up. Check your System Preferences -> Displays to see if it knows it's there.

How can I use my MBP's(late 2008) display as a secondary screen for MCP retina display?

I've got my new MBP retina dispaly and I would like to use my old MBP as a secondary display.
Is there any way to do this without installing different types of software like ScreenRecycler?
I tried to connect the only cable I have which is an HDMI to Thunderbolt cable but nothing really happened!

Thanks It actually works when you want to share the screen.
However I'm looking for using the old MBP's screen as a secondary display so that I can have two screens like an external monitor.
Also when you use the share screen it has some delay because of the wireless network.

B320 Display Blinking

After inactivity, my B320 frequently enters a state where the display blinks ON and OFF with an approx 1sec interval. During this state, the PC appears to be usable (mouse, keyboard, etc work fine...) its just not practically usable. The LEDs in the bevel at the lower right corner of the screen also blink, but the HDD, BT and WIFI LEDs do not.
The only resolution I've found is restarting.
So far I have updated the Intel driver and tried different resolutions, to no avail.
I'm not entirely sure how to trigger this, but it consistently happens when the display turns off due to inactivity then I come back.
This is a 6mo old refurb B320.
Any thoughts? Thanks, Nat

The problem just occurred while my B320 was in use, so it is not a result of inactivity.
Another user reported this problem, but it is unressolved: http://forums.lenovo.com/t5/IdeaCentre-Desktops-Home-Servers/Desktop-B320/m-p/768243/highlight/true#...

How do i get it to display the following?

so i want to basically type any numbers from 0-99 and have it display the following:
ex: 32.
Tens = 3
Ones = 2.

import java.util.Scanner;
public class Integer
     public static void main(String[] args)
          Scanner kb = new Scanner(System.in);
          System.out.println("Input number: ");
          int number = kb.nextInt();
          int ten = number / 10;
          number = number % 10;
          System.out.println("Ten : " + ten);
          System.out.println("One : " + number);

MBP not detecting external display

I encountered a strange problem today when I tried re-connecting my external monitor: it is not being detected by OS X.
I tried everything I could think of; I selected "detect displays" in preferences, I restarted the computer, I dis- and re-connected everything, I reset the PRAM, I tried connecting to a different monitor, and nothing seems to work. When I disconnect and reconnect the DVI cable, the laptop's screen flashes blue like it normally does, but nothing appears on the external monitor's screen. For the record I'm using the Dell 2209WA, and I haven't had any problems like this yet.
If anybody has any other suggestions as to what I should try doing, please let me know. Thanks!

Hey all, did a software update on my partner's mbp yesterday (10.5.8, security update 2009-006) and had the same thing happen where our external viewsonic display was no longer being detected. Plugging the cable in and out of the mini display port had the same effect already mentioned here where the mbp screen flashed blue like it was about to recognise the external display, but then nothing. Selecting detect displays from display preferences also had no effect. Tried resetting the PRAM and also the PMU, still nothing. So I shut down the mbp; disconnected the mini display cable; then turned off the viewsonic monitor at the power outlet and left it off for 10-20 seconds. Then I turned the viewsonic's power outlet back on, started up the mbp, turned the monitor on and plugged the mini display port cable in and the external display was back and working properly. Have shut down/restarted numerous times since then and it's all still working normally. Not quite sure how/why this busted in the first place, or why turning the viewsonic off at the power outlet seems to have fixed it, but it might be worth a shot for those experiencing similar problems... and it sure beats having to install/reinstall a different os version (which was going to be my next option)!

Mbp not recognizing external display

I have a 2010 MBP 2.8 and I'm trying to connect to a 24" Samsung LCD display to use as a 2nd monitor.   I'm using the mini display to DVI. And plugging a DVI to HDMI cord to that.
When I plug it into the tv and computer. The screen on computer flashes blue a couple times then nothing happens.   The computer is not recognizing the display.    I'm running Mountian Lion obviously and theres no option in "Displays" in preferences.
Am I doing something wrong? I had a old Powerbook G4 that I did this with all the time with Leopard OS.    Whats changed?

I recently purchased MBP retina w/Thunderbolt Display

I recently purchased MBP retina with Thunderbolt display. Also purchased Apple Care for the MBP. Does the Apple Care cover the Thunderbolt display also? Or do I need to purchase additional Apple Care for the display? Back in 2006 when I bought previous MBP with Cinema Display, the Apple Care purchase covered both. Does this still apply or have the rules changed?

Display corruption/system freezes

First time poster, so please excuse me if my post is misplaced. I am experiencing the same display corruption symptoms as this poster...
http://discussions.apple.com/thread.jspa?threadID=696575&tstart=0
"I am seeing this corruption on my PowerMac G4 Dual 1.42 GHz with ATY,R300 and was not using dual monitors at the time a 17" Studio Display @ 1080x1024.
I would describe it as a random pattern of vertical lines and bars that move around when windows are moved. Sometimes it fills the entire screen and other times it's just small random groups of pixels in a row or column on different areas of the screens. These vary in color from one incident to the next, but mostly all one color when it happens."
However, the similarities end there. My main issue evolves shortly following this (10min-30min of steadily increasing corruption) my system freezes every time. Regardless of app, yet it seems to freeze faster with processor intensive apps. I replaced HD, OS, and Ram to no avail. When I took it to a local shop, after 2 minutes he pretty much shook his head like he knew exactly what was going on, he had seen it before and that it would cost $750-$800 to replace the PROCESSOR. Could you please shed some light on this most distressing situation. Any info would be most appreciated.
Thanks,
Eddieglenn

I have the same problem with my computer also, but mine is a G5. I took mine to the shop and they told me it would cost me around $800 dollars. So it is a bad card. Well, how much does this cost? Is there a way I can install it myself?

When i disconnect my iPod 2nd Gen from my laptop, its display goes off and working freezes. Please help me.

The computer freezes? There may be something wrong with the USB port. If the laptop has more than one port, does this happen on any port? If you are disconnecting the shuffle cable from the computer, does it make any difference if you disconnect the shuffle at the other end of the cable first, then disconnect the cable from computer? Or if you currently disconnect the shuffle from cable first, try it the other way.
You may be able to work around this problem, if you get a self-powered USB hub. Something like this one
http://eshop.macsales.com/item/NewerTech/USB2HB7PRO/
There are many choices, but be sure to get one that has its own power supply. You can leave the shuffle cable connected to the hub, and connect the shuffle to the hub, instead of directly to the computer. This may provide a "buffer" for whatever is causing your laptop to shut off when the shuffle is disconnected. Since the hub has its own power supply, it will not rely on the computer for power to re-charge the battery.
