White screen when I turn the Satellite M50 on

I intermittently just get a white screen when I turn the computer on. Usually the problem is solved by switching the computer off and trying again - but sometimes I get a white screen again.
It seems to be connected to use of external devices - can anyone give me clear instructions about what should/should not be connected when I start and shut down the computer? Or any other suggested solutions?
Thanks

Thanks for your reply/advice - and the tip about Antivir. I used to use AVG and then Norton came as a package with this laptop....will have a re-think when my subscription need renewing.
I have updated the display/graphics driver but am still having the same problem of a white screen at boot-up. On reflection I think it is possibly a loose connection as I have just been a long trip with the laptop - including a fairly bumpy 4 hour bus ride - and I recall having the same problem several months ago which self-corrected after a similar trip (taking it down to a Toshiba ASP who never saw it as they were closed for the week-end and I had to get back to work!). This may sound strange but I took the laptop for a walk yesterday to see if any loose connection would shift and it then booted up on the second attempt rather than the 8th!
I guess I'll have to take it to the ASP - unfortunately it's no longer under warranty.
EDIT:
Problem solved. High temperature caused this issue

Why does my Mac stay on the white screen when I turn it on?

Why does my Mac stay on white screen when I turn it on?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 4
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 5
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 6
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 7
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 8
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 9
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 10
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Hello all,
I have a 14.88G iPod Nano that I currently use as my primary watch. A week or so ago I started to experience a blank white screen when I press the "sleep/wake" button instead of the watch face (I have it set to wake from sleep to display the clock). When I hard reset it, it will come back fine and the screen will respond and work as normal, as soon as I manually put it to sleep by pressing the "sleep/wake" button and then try to wake it the same thing happens and I have a blank white screen that doesn't respond to touch gestures or anything.
What I have tried so far to no avail:
Numerous hard restarts (holding the "sleep/wake" button with the volume - button).
Tried this: iPod nano (6th generation): Hardware troubleshooting
Changed the watch face to display.
Recharged the device overnight (without full discharge).
Since none of this works I'm out of ideas. Eventhough I have a 6G Nano it should no longer be under warranty since I was sent it as a replacement for a different (older) product.
Any ideas? Is this a known problem? Thanks in advance for any insight any of you could provide. Also, what time is it??
Regards,

Hey,
I have the exact same problem as you have described. I also used my ipod as a watch but starting from today, whenever I unlock it the screen turns white until a reset is done. Even a factory reset through itunes didn't fix it.
Have you found any solution?
Bah, this is annoying.

Mysterious white screen when waking up the phone by using the lock button

Anyone else experiencing this?
Every now and then (about 5 out of 10 times) when my phone would fall asleep in an unlocked state, and i press the top lock button to wake it up, my screen turns white for a few seconds before returning to its normal screen. This doesn't happen if i wake up the phone with any other key (including the silent button on the top). I am only having this issue with the lock button. Is this something that is normal on all 8900s? Or can this "issue" escalate to something more serious? Any input would be great. Oh by the way, i already tried multiple battery pulls (did not help).

I am unable to get into the chat. I tried explorer and chrome and neither will allow us to access the chat. It continues to go around and around.

White screen when I turn on the computer

My Macbook Pro would not let me click on anything so I restarted my computer by holding down the power button, but then it stayed at a white screen for awhile, then turned to a blue screen before my login screen poped up. It let me log in but then would not let me click on anything after that. When I moved the mouse cursor where my dock would be it does not appear. Then after a half hr of it still not allowing me to do anything I restarted it again and now it is stuck at a white screen. I am not sure what is going on because my computer was working completly fine yesterday. Im not completly positive on my operating system, but I know its a 10.5 something.

That happens. One day it works fine the next not at all.
Do you have the original system discs that came with the system? Id you do get the OS reinstall disc and insert it into the DVD drive and reboot (hold down power button until the system shuts down then pres the power button again to start it back up). When it is starting hold down the Option key and if a screen comes up, other then the white screen, select the DVD disc to boot from. If that starts up then open Disk Utility and check the SMART status of the drive and Repair Disk and Repair Permissions.
But I suspect the drive has failed and will need to be replaced.

Gut white screen with flashing apple and circle/warning sign on white screen when i turn on the computer

When i turn on my computer, i get only a white screen with a gray apples in the middle, flashing, alternating with a ghostbuster-type warning. Never get to the galaxy screen. Just happened today.

Did you setup a lock code? I have done this operation via iCloud just few minutes ago and it's booted with 4 numbers lock code just fine. When you lock your Mac, it's restarts automaticly and then loads with lock screen and you are only able to enter password of 4 numbers to unlock it.

White screen when computer turned on. Software problem?

I have had my macbook for about 4 months, and it spent 3 months being repared! The first time for a problem of batteries that made the computer heat too much and turn off, and the second time because when i wanted to turn the macbook on, there was only a white screen with colored vertical layers on the screen, and impossible to do anything else than to just turn it off pushing the on/off button. They changed the CPU (it took them 2 month to change it btw) and gave it back to me 5 days ago. I used it twice this week end to watch a DVD and yesterday when i tried to turn it on, i had this white screen again! I called the hot line and they told me they heard of this problem but did not know what it was. they said they could talk me through some repair procedures on the phone that might help, but i needed to pay 50 Euros for it, although the computer is under warranty, if it's on the phone since it's faster we must pay! I was pretty upset and just hanged up and called my brother who told me to press 4 keys while putting the computer on and keeping those 4 keys pressed while the computer would turn itself on 7 or 8 times. After that i let the keys go, and it worked. Now the computer is working but i don't dare turning it off in case it wouldn't turn on again. So i'd like to know if anyone have had the same problem and might have an answer for this. Apparently it's not the CPU since it's new (unless i'm really unlucky and got a broken one twice) so maybe it's a software problem?
Also since it will be the third time in 4 month i bring the computer to repair it and i have not been able to use it more than 3 weeks, i asked if i could just exchange it and have a new one, and i'm told that's not possible, there has to be a commition to decide whether they can just replace it or not. I'm very upset now and disappointed with Apple!! Does anyone know how to make this computer exchange procedure a bit faster?
Thanks for your help

Yes, i have tried that! They say the macbook has to go 4 times into repair, and twice for the same problem so that i can change it.
It is completely unbelievable. I am so disappointed with apple right now!
Thanks for the advise though

Black screen when I turn on Satellite M

When i turn on the notebook, i cant get into the system, just black screen, after i tried several times, then i can get into the windows system.
What is the problem???
Tanks ,buddy

Hi
Are you able to access the BIOS?
If not then there could be a motherboard problem
Did you try to connect the Satellite notebook to the external monitor to check if something would be visible on second screen?
I think this would be helpful to get more information about possible hardware issue
If an second display would stay black too, then an graphic card issue might be possible
However, I doubt you could fix it yourself. In most cases its a job for an technician

HT1414 My ipod touch shows white screen when i turn on. And, it does not register in my computer.

My Ipod touch don't start up as usual. It doesn't register to my PC. It shows white screen and some time other colors like green and blue. I trying restarting, but that did not work. I cannot restore the IOS because my Ipod touch doesn't even shows up in my Computer.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device 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.

My MacBook Pro has a white screen when I turn it on

When I start up my MacBook Pro. It just ha a plain white screen and I can also hear a faint beeping (like if you were on a desktop computer holding down a lot of keys on the keyboard) please can someone help me!!??

I can tell you what I did the last time this happened to me:
I made a careful note of my Display settings when my computer started up correctly and everything looked fine
... and, I ensured that the same settings were there the next time I restarted (and it happened that my screen didn't appear to display correctly) I checked these settings. If they had changed, I chose the one that 'worked' for me and it 'set' thereafter. In my case, it was 1280 x 800.
If I were you, I wouldn't shut down my computer too often (just telling you what I do.) I shut down mine only after a week or 10 days so that it can 'clean itself up.'
Hope this helps.
