Flicker/flashing screen (Qosmio PX30t)
Hi all
I have a weird problem with my desktop computer (all-in-one). A few weeks ago the screen began to blink/flicker violently for no reason, I had no idea what was wrong, but when it is started in safe mode it would go. Ultimately I ended up reinstalling the operating system and drivers, and at first glance the problem was gone. It is only when the brightness of the screen DIMMED as the flashing back.
I later discovered that if you change the brightness of the screens even a flashing light came back big time. At that time, I had upgraded to WIN 10 and installed all the new drivers for this OS, in the hope that this would solve the problem, but without success.
Basically where I'm at right now - as long as I don't touch the brightness of the screen it seems fine, but if I turn off the graphics driver I am able to change the brightness without problem or use the Eco mode. I tried a driver installation and re installation with no luck. Is it perhaps all pilots our there I could use instead (currently using GPU Intel(r) HD 4600)? or any other measure maybe I missed.
PS: another weird thing, that I just discovered. If you adjust the brightness of the screen another full then disable the graphic driver, the remnants of turn signals. However if you turn off the graphics driver while the display brightness is set on full you can change brightness without problem. Is crazy.
Have no idea what the step to try next. Any help would be much appreciated. Thank you for your time, Nathan
Updated - I just booted the computer in safe mode and went to the Device Manager. There is a yellow Triangle warning next:
Monitor - Monitor generic PnP
Any ideas on what could be the solution? or is this a hardware problem? Any help would be much appreciated. Thank you.

I thought it would be the best forum page to post, but in any case I had trouble with these two things. The first is this random/flicker flashing, screen tapping the top of the screen could delay, but this is very random and makes sometimes standby extended or even restart more rare. I don't think overheatiing is because it looks cool enough. Very random though sometimes it happens not every day or a few days.
The power button is very recent, it turns that if I do something such as unplug it or open/close the screen as I've seen, really don't know where these two could come, but this laptop is second-hand on ebay with a new OS installed.
The HARD drive error is common so I saw, so I can deal with it. The usual startup error, a reboot solves this problem and it starts to load normally, have not seen all the patches, in addition to a clean wipe I don't want nessiserally to do.
A few things you might want to know:
OS: Windows 7 Edition home premium
Quad core i5
graphics card intel integrated (use an ATI mobility Radeon HD 5650)
Just ask if something else should be, thank you.
I suggest to retrieve what you saved on your laptop and replace the HARD drive, you now have. It seems that the HARD drive, you may be out of any day. Make sure the replacement HARD drive is not too big.

Flicker flashing white screen...
My computor screen starts to flicker, flash, then the screen turns white and the computor freezes while remaining on. Does any program I am running, music, internet, word etc... Any ideas?
This is a portable computer or a computer?
If the computer screen is blank how do you know that the computer froze?
If it's a computer you can try another screen see if you get the same problem. If it is a test of the laptop an external monitor and see what happens.
If it's a computer. There may be value to unplug monitor and resecuring cables and also re-seats of the graphics card (if it has separated).
If it's a laptop - when it is empty... If you look very carefully or shine a bright light on this subject from a perspective you see the picture?

Qosmio PX30T-OOM: Questions about specifications
I looked in the specifications for the Toshiba PX30T-OOM online and see no mention of this hard drive comes with this computer. Can anyone provide this information please?
In addition, this computer didn't go out 3D on a 3D TV? I guess that the screen of the computer itself does not support the 3D visualization?
It seems that this computer has a TV tuner, would that be a DTT tuner?
The specifications indicate that the has PX30T of a drive Blu - Ray RW/DVD SuperMulti double layer. However, a seller tells me that he is not a Blu - ray player. Can someone tell me the correct situation on that?
In addition, "Blu Ray RW" means that the PX30T can certainly record to Virgin blu ray BD - RE media?
Thanks for your help.

Qosmio PX30T-A-14r: how to change the type of keyboard language
You just bought an AIO Qosmio px30t-a-14r / windows 8.1
At the start, during the first installation, I had to choose the language and keyboard settings.
I chose the language: English-uk.
For the keyboard, I had the choice of 3 types:
-Belgian comma
-dot Belgian (or point?)
-Belgian french
I chose Belgian by commas.However, later in the installation process I was able to test response of the keys on the keyboard with this configuration.
It was the wrong setting.How can I change to "Belgian point" or "Belgian french.
Should be one of these 2 but I don't know how to change it.Has anybode a suggestion?
Thank you
RCIt is not very complicated:
Press the Windows key + C to open your charms... Then select the charm of settings and then click Change PC settings. Click the time and language, and then select the language and region. On the right, select your language, and then click Options. Click Add a keyboard, and then select the keyboard you want in the list.
This will add your selection to the list of keyboards.
You can remove a keyboard by clicking on it and click on delete.
In addition, you can also add several keyboard layouts and switch between them when necessary.You can switch between your keyboard layouts by clicking on the language and the keyboard at the bottom right and then select a keyboard layout. Or you can use the 2nd method: on your desktop, you will see your current language in the lower right corner next to the clock. Click on your current language and choose a keyboard layout.

All-in-one - Qosmio PX30t - Bluetooth driver for Windows 8
Hi, guys!
Please help put Bluetooth on my new Toshiba PX30T.
All devices which he founded are offline and when I tried to download additional drivers, that it cannot install it, saying something like "has nothing to upgrade. But this model has Bluetooth...
It is Windows 8, and many people say that you need to download drivers for it to successfully run the Bluetooth.
Has anyone had the same problem?
What did you do?Thank you very much in advance for your answers.
Hello
I confused m.
Firstly what Qosmio PX30T do you have exactly?
Not all models support the same features!Second: I know the series of PX30T was already pre-installed with Win 8.
Everything has been implemented and installing drivers extra isn t necessary.
That's why I put t understand why you want to install driver BT (BT support function), if it was already installed.I think you should check if BT has been activated.
Press the Win + C-> change PC settings-> Wireless-> slider Bluetooth on / offIf its greyed out, it means that BT could not be supported.

HP Elitebook 745: HP Elitebook 745 flashing screen
Hello
I have problem with my screen in Elitebook 745 (HD resolution +). It's strange pixels flickering on white background. I recorded a short video to introduce this issue: http://youtu.be/yRk643s59Eo
It is only visible from certain angle. I have never seen this before on other laptops (even on the older). I tried to change the resolution and refresh rate, but it does not help. I checked the different systems (win 10 and Ubuntu).
Would be - this technical problem or maybe a kind of "function of the screen? My eyes really hurt from that.
I've updated the BIOS with the latest version (1.10) and fortunately flashing screen no longer exists.
So this was a firmware issue, not hardware.

Satellite Pro L450D - 12 X - flashing screen on and outside
* Satellite Pro L450D-12 X flashing of the display on and outside *.
Can Hi anyone help?
I have a laptop Toshiba L450D-12 x, when you start the laptop, the screen is flashing / blinking on and non-stop.
The screen turns on seconds, and it does not stop, becomes faster and faster!
The operating system loads up, I can not connect, but everything else seems fine.
Here is a list of what I've tried,
1. connected to an external monitor - on the monitor, the screen does not flash, but on the laptop it is flashed!
2 replace the cable with a new one - continuous flashing screen
3 replace the inverter - continuous flashing
4. replace the screen - continuous flashing
5 reset the default settings of the bios - continuous flashing
6. started in safe mode - continuous flashing
7 install the latest driver - continues to blink
8. removal of ram - continues to Flash
9 deleted the hard drive - continuous flashingPlease help, I don't want to replace the motherboard and then find it is not the motherboard
Concerning
RAF
> Please help, I don't want to replace the motherboard and then find it is not the motherboard
In my view it's hard to say what's wrong here.
You said that if you connect the external monitor, the display is OK means (in my opinion) than the motherboard and graphics card should be ok.I think you should visit a next engineer downtown to get verified material sound much less expensive than buying the following parts.

My HP DV2000 laptop started to re-start a flashing screen and my hard drive flashes continuously. He worked min a fine then restarted the next day. can you help me?
@herbairob1
This error indicates hard drive has failed. You can replace it with a portable HDD SATA of detail. Just be sure to get the replacement which is at least as large a capacity that the original if you plan to use recovery disks to reinstall Windows. New hard drive may be more capacity but may not be less.

I would like to point out something that you may not realize: Windows 8
has two interfaces; the modern/Metro Interface (which may be all the)
you have looked at) and the traditional desktop Interface. You can use
one or both. This traditional desktop Interface is almost
identical to the interface of Windows 7. the biggest difference is that
There is no Orb start clicking to bring up the start menu.But note that you can get the ORB start by using one of the many
third-party programs, are free or very cheap (the classic interface
http://classicshell.sourceforge.NET/ and debut8 to
http://www.stardock.com/products/start8/; my personal preference is
Debut8, but they are both very good). And goes from an interface to
the other is very easy; There are several ways, but simply by pressing
the Windows key is perhaps the easiest.Just install one of these two and using the traditional desktop computer
interface may be a better choice for you than going to Windows 7.
I use Windows 8, almost exclusively with traditional workstations
the interface and with 8 Start installed. If you were to look at and use
my computer, you may have a hard time realizing that it is not
Windows 7.
I also recommend to read "how to make Windows 8 or 8.1 watch and.
Want Windows 7 "to http://www.howtogeek.com/elk/298/45121/4206
I can't address the issue with your games, except to say that
whenever you move to a new version of the operating system, some of
which is used to run on the former does not work on the new. And it's
much more likely with utilities and games with companies
applications. -
Qosmio PX30t all-in-one: black screen after a few minutes of inactivity
I just bought a new all in one Px30t and I have 2 problems with it causing me to nuts.
I have a mouse battery that dies after 24 hours and the screen goes black after a few minutes of inactivity.
I changed the settings of the display in standby, the Power Options etc everything I can think of it doesn't seem to make a difference.Can also someone point me in the direction of a manual online for the model.
> The screen goes black after a few minutes of inactivity.
Can bring back you to life somehow, or you need to restart your Qosmio?Usually the manual s user document is saved on the HARD drive (preinstalled original machine). Can find you it?
Did you check support page to Toshiba for manuals online (Toshiba page for the country of purchase)? -
Re: Qosmio F - flashing screen with AC adapter / CC

I have a problem with the fo my qosmio screen. When turned on ca it flashes when it is not only with the battery.
Do you think that this is a problem with the adapter only?Thank you
PanasHi panas,
If this happens with the AC adapter / CC only he could be a grounding problem. Are you using the original Toshiba AC/DC adapter or the adapter part 3?
By the way: laptop Qosmio what you have exactly?This also happens if you connect an external monitor or only with an intern?

Help the flicker of screen HP Elitebook 8460p &; question flashes and upgrade.
Greetings,
I have a problem with my Elitebook 8460p. My old servant me service for 3 years. We have a good relationship with highes and downs. Changed hard drive, the improved Rams, monthly cleaning and etc.
In any case; I have a problem with flickers and flashes. When I push the start of (the computer On / Off), some strange black lines appear and never went. The funny part is that the black lines, flashes / flickers become crazy when I touch the touch pad. But if I touched the touchpad of the black lines just less.
Things I've done;
Electrical parts Checked - no electric leakage (verified to the ohmmeter)
I tried to run with AC and battery - nothing has changed.
I've been handicapped ambient light sensor - nothing has changed.
I've been disabled touchpad - nothing has changed.
Formatting, update the BIOS to the latest version of w7 updated, no unknown device, performed stress test CPU GPU & played back & assemble nothing has changed.
My suspicions;
CPU because this computer VGA card integrated with CPU. Change CPU, maybe to fix any problems.
I want to switch my computer to my choice and i7: Intel Core i7 - 2670QM.
My booking / questions;
Intel Core i7 - 2670QM CPU is compatible with my Chipset QM67? If it is compatible; What should I do? (Updated the BIOS, or different version of BIOS etc..)
I have some information on this situation and my laptop.
HP Elitebook 8460p series using Hannstar MV6 and my motherboard is same. No VGA. I will not worry the my solution. If I'm wrong; I spend my money for nothing.
I'm waiting for your answers.
Thank you.
Really? No response. Thanx HP.

Apple Watch after upgrade to watch OS 3 - flashing screen after update
Apple Watch 42 mm
I recently like millions out there I've updated my Apple Watch to watch OS 3. Today noon 15/09/2016, I noticed that when I raised my hand/wrist to wake up screen Apple Watch it flickered once. I did this action several times to confirm that I clearly understand what was going on. I started to solve the problem, powered off/on power the Apple Watch. Issue continues. I did a reset on the Apple Watch hold the button of the Crown and the power at the same time until the powers of the device and restart. This action eliminates the problem. Apple Watch works as expected, screen flicker stopped when hand/wrist is triggered and screen Apple Watch wakes up to the top. Unfortunately, after some time between 2 and 3 hours of new screen flickering starts. I did some digging online but have not encountered this problem. I realize that the watch OS 3 has only been published days before so I wasn't expecting to fall on part.
My question: is this a known problem that will be patched with an upcoming release or I'm the first to report this problem? Any information would be much appreciate.
It is too early to know if it would be regarded as a known issue. This is not the case on my Apple Watch after the update.
See if a matching and re pairing your watch makes a difference.
