Screen goes blank for a fraction of a second

hi all,
i just got a macbook pro two weeks ago. I am pretty satisfied with this laptop but since its my first mac experience and i am expecting mac's to be perfect there are a couple of things ( may be minor) that are bothering me.
first is, while working on my mac i have noticed the screen goes blank for a fraction of a second.
second, i have mighty mouse but at times it stops working as well, in the bluetooth menu it shows that my mouse is connected but it won't work, so then i have to disconnect it and connect it back again.
should i take my macbook to apple store or what
any suggestion would be appreciated.
thanks

The screen goes black for about 1/2 a second.

The screen goes black for about 1/2 a second. Is it time to panic?

I don't see any common link. Sometimes it is just one 'instance', sometimes it is several in a row. But there doesn't seem (to me) to be any sort of common circumstances. (Other than that I am using the computer!!)

Help! I just installed the latest update on my IPhone 4 and now I can't access my podcasts. When I hit the podcast I on, the screen goes blank for a second and then opens to the home screen with all my icons. What happened?

Try a reset which is similar to a computer restart and is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously you see the Apple logo and then release.

Hell yeah.

When I click on my Messages app I can see it for a brief moment and then the screen goes blank. This happened to me last week and I Reset All Settings, which worked-but it has just happened again so that's not a long-term solution.

It may help to force close the Messages app, then restart the device.

Displays call for only 2 rings then the actual screen goes blank

I have a 3GS and already had it changed once. When someone calls, the screen shows the caller and then after a couple of rings, the screen goes blank/black. The phone still rings but you cannot then see who is calling and you have to click on the home button. My old iphone 2G did not do this. Does anyone have the same problem and/or know how to solve this?

Shut down and restart the app...
- From any Home Screen, double tap the home button to bring up the Recents List
- Tap and hold any icon in this list until they wiggle
- Press the red to delete the Mail app from this list.
- Press the home button twice when done.
- Restart the Mail app

When ever i insert microsim my screen goes blank with just apple logo on screen ...Without sim it is ok...I dont know what to do

I just recently bought IPAD2....Whenever i inserted my microsim into sim tray, the screen goes blank with only apple logo to show...It does not start till i remove the sim and press both Home and Power buttons simulataneously...Can somebody help what shall i do????

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

When I am on a phone call and I double click the button to go to my home screen, then open another application (usually my calendar program, Calengoo), my screen goes blank and I am not able to return to either the app, the phone, or the home screen.

When I am on a phone call and I double click the button to go to my home screen, then open another application (usually my calendar program, Calengoo), my screen goes blank and I am not able to return to either the app, the phone, or the home screen. If I am speaking to a person, if they hang up then I am back to the phone application. If I'm leaving a message, I am unable to return to the phone screen to end the call, and have to wait until the other phone hangs up. I'm also unable to switch back and forth to look at my calendar if I'm calling someone about scheduling. This has only started happening since the most recent iOs update. I run into situations similar to this about once per day during the work week, as I use my phone is this manner quite often. While not life altering it is quite frustrating. Can anyone here help me figure out a way to avoid this? If it helps, I have noticed a general downgrade in overall performance starting two system updates ago (apps opening more slowly, closing unexpectedly more often, etc.). I have an iPhone 3GS with the latest OS update.
Thank you for any help or suggestions,
Chris

I could be corrupted backup.
You can check the notification settings for message.
Settings>Notification Center>Messages>Alert Style
It should be on Banners or Alerts.
Settings>Messages> Turn on Imessage and send as SMS and below that "Blocked" to check if you have any numbers block might be blocking the message.
You can also do a hard reset by holding power and home till it restarts and release after seeing the apple logo.

Screen Goes Blank, Hard Drive Stuck, Cannot Re-Install, or recover

I have somewhat a bizzar problem that even with several years of IT experience I seam not to be able to figure it out. I thought I toss it our here at Toshiba community in hopes of people's collective experience shedding some lights on my problem.
I hava a 3 year old Toshiba Sattellite A305D with updated BIOS to version 2.10. It came with Windows Vista Home 32bit and I had upgraded it to Windows 7 64-bit last Christmas. It was working fine till last month that I started getting sporadic blank screens. Here is the symptome with details: screen goes blank, backlight it on, but there is no content on screen. At this time the Hard Disk Drive activity light is steady lit. Initially the problem happened intermitently and sometimes it fixed itself after few minutes and screen would come back on, but when it started to happen more often, I started to look for some troubleshooting. Some people suggested that blank screen could be due to bad lid close button being stuck or Windows power management's CPU power being set to 5%. I have tried cleaning the lid button and fixing power management but no luck. Then, I tried re-installing Windows from DVD, screen never went blank till after the first few steps of setup to the point that it says "Extracting Windows Files". At this time I started to think this is a hardware issue. I took out the RAM, I installed it on my MacBook Pro and used it for few days, and I had no problem. I even diagnosed them with Windows Memory Checker in the list of Recovery Options and no problem was detected. So, the next suspecious thing was the video card or display inverter. I tried connecting the laptop to an external monitor to test the screen's inverter, and same thing happened and external monitor went blank. I used Windows Recovery options and left it on that screen over night and nothing happened so I concluded the video card is fine. Next, I had turned off the Wifi and Lan, but nothing seamed to change, so I concluded those are OK as well. My last coclusion was that the hard drive is bad. I took the drive out and coonected it to my Desktop PC and ran disk utiility scan to check for bad sectors and none was detected. So, I thought the drive might be totally broken. I went to local electronics store and bought a brand new HITACHI SATA II drive and installed it. At first same thing happened so I gave up. Since I didn't have the recovery disks, I ordered recovery disks from Toshiba and tried that. Save thing happend and as soon as it started copying files, it blanked out. OK. So this time I ran a different recovery option and formatted the entire hard disk and zeroed out all sectors. That took approximately 3 days to finish for a 500GB brand new hard drive. Seams a long time.After that I could install Windows 7 64-bit from scratch up to the end. However, things got gorry again when I started installing Updates and driver packages. I had read about some problems with ATI drivers and Catalyst software with .NET updates, so I did not install any driver from update site and made sure all .NET updates are installed. I had to install the updates slowly chosing a few at a time. Otherwise same thing would happen. I got stuck to the point that I could not update anything. Windows files seamed to be corrupt and turning on/off Windows Features in controll panel was blank, so I had to re-install again. I did Re-install successfully using the upgrade option. This time I installed .NET updates first before any other updates. Then I started downloading all Toshiba drivers. Aazingly, the laptop worked for few ours without the symptom. I managed to install most of the drivers and updates including Value Added Package, HDD/DVD Rom Patch, Registry Patch, Sound, Modem, Atheros Wireless, and Catalyst. Up till now things were ok. Then I ran Toshiba Hardware update patch, and things got really messed up. Windows never booted again and symptoms showed right after boot tried to load WIndows. I tried recovery options but System restore kept getting errors too and I could not restore any more. Since Windows 7 Install and Windows Vistal recovery to Factory Default from recovery disk did not work, I thought maybe I should try Windows XP. So, I got a hold of my old Windows XP CD-ROM and I took a stab at it. Everything went fine till it started to copy windows files. This time symptom was different. I got one of those XP Blue Screen of deaths saying Hard Drive is bad and I must run chdsk /F. So, I concluded HDD is the problem. Ran CHDSK and no problem. I formated the drive again using DISKPART and the problem still exists. This is a brand new hard drive. What is the problem?

Please include your full model number when posting problems on the forums. It can be found on the bottom of your laptop. "A305D" is only partial.
That's quite the problem. How often was it doing this? At some steps in your diagnosing, it seemed to get better, but I wonder if it was actually (temporarily) fixed, or if it didn't occur by chance.
Unfortunately I don't have an answer for you. Normally I'd suggest you get it serviced, but then you'd also be throwing more money at a three year old notebook when clearly you're knowledgeable yourself.
Hopefully someone in the community will have some suggestions. I have noticed that some people shy away from posts with large paragraphs of text. (I'm not saying that's correct, but it happens.) I'd suggest putting some bullet points at the top summarizing. If you feel like doing that, you can edit your message.
Good luck!

Unmountable Boot Volume on XP and screen goes blank before repair begins

The XP Windows partition was seemingly working fine until I turned on the laptop this afternoon. Took a minute or so longer to boot than usual and I was prompted when it did load to update Acrobat, which I did and it rebooted. Took longer to boot, perhaps two or three minutes and I received an Unmountable Boot Volume error. I rebooted a few more times, same result. I tried system restore to three previous dates over past ten days and was told after attempted reloading that it had failed and I should try another day. Worried about my data, I went to safe mode to back up C: drive.
The general advice from MS is to use the Windows installation CD to repair the boot sector. With the CD in, Windows will boot and show my normal desktop and files, though will on perhaps the third item to load to memory, the screen goes blank and the loading seems to continue, as I hear sounds though not sure if it is the programs or the repair.
There does seem to be an ability for it to boot, just not maintain it through full load. Any suggestions short of reinstalling windows would be welcomed. Thank you.

I was unistalling some usless programs when my laptop died & when I turned it on I had unmountable boot volume 0x000000ED (the blue screen)
If I hit repair windows it goes to a black screen with the mouse (nothing else)
Now I tried f8 & then did command prompt but after it had gone to the loading files screen it had gone back to the blue screens with unmountable boot volume 0x000000E
I DL windows 7 repair but how do I get it to install when I cant get past the blue screen?
so i decide to repair it my self and then i found this great solution what helps me

Ipod nano 5th gen - works fine when plugged in either to wall or computer and appears to be fully charged but as soon as it is unplugged screen goes blank and will not start - is the battery shot?

Yes, your battery is likely toast and in need of replacement. Not much else for troubleshooting here. Sorry.
