Equium P200D-139 suddenly goes to blank screen and has to be rebooted

Hallo,
Have a Toshiba laptop: Equium P200D-139. Just reinstalled vista (because laptop was glitchy and slow) and computer has just started going to a blank screen randomly, no error reports..nothing.
Works fine after it has been rebooted, have restored in safe mode, uninstalled updates....but have run put of ideas.
Would appreciate some help, thanks.

Hmmm. my notebooks screen was blank sometimes after wakeup from sleep mode.
But after new reboot everything was OK.
I searched a little bit in the forum and found some people who have recommended a BIOS and display driver update.
I did this and could solve my issue
I, not quite sure if this would be helpful but try this too
Its worth a try

My iPad 2's app store is just a blank screen and has been for 2 days! I am currently running ios 6. Can someone jelp?

Can someone please help??

Force close the App Store app and reset the iPad. No data will be lost when you reset the device.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

My imac OSx 10.9.1 keeps going in to standby and has to be rebooted any ideas?

I have recently reloaded my i mac from scratch and installed 10.9.1. Despiite the energy savings being set to "never sleep" when the screen saver kicks in it will not come back to life and I have to rebot. Has any one else had this issue?

Hey there Murky,
It sounds like your computer is not waking from sleep properly even though you have the devcice set to never go to sleep. I have a few recommendations to try. First reset the SMC on your computer:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
Then perform a Safe Boot, and then leave Safe Boot.
OS X: What is Safe Boot, Safe Mode?
http://support.apple.com/kb/ht1564
And the last step is to reset the PRAM of the computer.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information.

Equium P200D-139 screen with horizontal lines

I have a Toshiba Equium P200D-139 laptop and the screen stopped working.
It lights up but the display consists of vertical lines, which slowly fade into a black screen.
I tried it on an external monitor and it worked fine, (so presumably cannot be a faulty graphics card/motherboard). So, I thought it was likely to be either be the inverter or the screen itself.
After trying a new inverter with no success, I bought another second hand screen.
However, the new screen has the exact same problem with the horizonal lines display.
Just occassionally, I catch a glimpse of a partial Vista screensaver for a split second but then its back to black. Im not a technophobe, so any info would be very much appreciated.
Please help, as it is driving me up the wall!

>I tried it on an external monitor and it worked fine, (so presumably cannot be a faulty graphics card/motherboard). So, I thought it was likely to be either be the inverter or the screen itself.
Right. I think the issue is related to the display
>However, the new screen has the exact same problem with the horizonal lines display.
Well, it could be possible that the second screen is faulty too if you bought this as second hand part then it could be possible that you bought a screen which does not work properly.
What to say; its difficult to say what you should do as next. Buying a new screen and to check this again? Well, I think I would visit the next computer repair store and would ask for checking the display.
I think this is the best solution in your case

Cannot access Windows on my Equium P200D-139

Evening,
I have a Toshiba Equium P200D-139 laptop. I am trying to format the hard drive and every time I turn it on, it goes straight to a password box straight after showing the Toshiba logo. The box says hit F2 or F12 as normal, which I do, The password box comes up next. Its not a windows password, as windows does not load.
I think its a set up/BIOS password. Any help in bypassing this would be much appreciated. I thinking along the liones of removing the CMOS battery, Any ideas, Please bear in mind that I cannot enter the BIOS/ or set up page Many thanks NODDY.
Please reply to my email
[email protected]

Hi
Yes it must be BIOS password. In the whole story it is a bit strange to me that you are wondering about this.
Is this your notebook or you got it from someone?
Fact is that you will not be able to have access to preinstalled Windows or possibility to install new Windows if you don't have right BIOS password. Password removal is not information for public forum so if you need help you must contact Toshiba service in your country. They can remove it for you.
As far as I know CMOS battery removal will not help you to remove BIOS password.

When I turn on my iphone4s, the apple logo will show for a few seconds, and it will suddenly fade off to a blank screen, and not start up. It will then restart by itself, and the cycle repeats. Any suggestions on how I can troubleshoot this problem?

I can't download apps! Every time I try, it asks me to chose a security question and I try, but I just comes up with a blank screen and I can't choose a question. If I click no, I don't want to put security questions, it doesn't install the app. HELP!

I can't do it! I am willing to add questions but I can't because it just shows me a blank screen. I even tried rebooting my entire iPad2 and that didn't work. I know it is not a certain app because I tried multiple ones.... HELP!

found answer on another thread...passing along

Hi all! I have found the answer in another forum and this has 100% worked for me!!!
1) Quit App Store in multi-tasking.
•From the Home screen, click the Home button twice.
•Tap and hold on the app.
•When it starts to jiggle, tap the red ⛔ in the top corner to close it;
***Please close all open apps on your phone***
2) Tap Settings.
3) Tap Safari.
4) Tap Clear History.
5) Tap the Clear History button.
6) Tap Clear Cookies and Data.
7) Tap the Clear Cookies and Data button
See the answer in context
I hope this helps a lot of people!! Spread the word (seeing as apple doesn't seem to want to/care!)

The application maps is not working. When I try to run it opens for a few seconds with a blank screen and then closes.

Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.

My iPhone is fully charged and just gives me a blank screen and will not turn off, what do I do?

Reset the phone like the manual says: hold the on/off switch and the home button simultaneously until the Apple logo appears. May take up to 30 sec

Unfortunately I tried that and it didn't work. Thanks for the help though. I tried to uninstall and it said I couldn't because the file is corrupt or something, but I think I finally got it uninstalled and/or deleted or whatever, but now I try to reinstall/download it again from the beginning and I can't. No matter what I do I can not get Firefox working again. No matter how many times I try to redownload it. Any other suggestions?

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
