Toshiba Satellite U400 - Purple lines on screen

Hi, I have had my laptop for about 2 years now and recently I have noticed that when the screen is dark coloured (like a black background or dark background) purple fuzzy horizontal lines appear on the very top of the screen. Like the top 2 millimeters of the screen.
I also noticed that when i put pressure on the area around the touch pad the whole screen starts to glitch out and go spastic. Like purple lines everywhere. Especially around the taskbar at the bottom of the screen.
If I set the background to white the lines disappear however and the affects of putting pressure on the area around the touch pad are far less noticeable (if at all, I have to test this more)
Also when I plug in an external monitor (VGA) there are no problems on the external screen.
So my question is, has anyone experienced something similar and also would this be a software or hardware problem? And what steps should I take now?
Thanks

Sounds like a hardware problem. If the screen garbles when the base is pushed, then the graphics chip is probably faulty. An ASP can quote you a new Mainboard.

Picture Included. Mid 2012 13 inch Macbook Pro green/purple lines on screen. Freezes. Sometimes 3 beeps.

Alright I have a Mid 2012 13 inch Macbook Pro purchased in June 2012. For about the last month, I have this issue where as I am using it random colored lines will show up on the screen (lines usually green, purple, but occasionally the issue occurs while booting and lines are black on white background). As soon as the lines appear, everything freezes. Sometimes the computer automatically reboots. Other times, it will just turn off and start beeping 3 times in a row. AT first, I thought this may be a video card error because it happened a lot when I was watching videos. However, it also happens randomly when I am just using safari/chrome with no other programs runnings. The most annoying part of this issue is that it is completely random. Computer won't act up for maybe 2 days straight during all activities (videos, surfing the web, etc). Then I will have a day where the problem is consistent.
Also, although I think this is just a correlation, all problems started after upgrading to Yosemite.
Picture below:
Does anyone else with a Macbook Pro (especially 2012) have this issue? These two discussions seem to be describing this very situation:
Screen froze, purple lines, three beeps. Help!
Macbook Pro screen glitches, 3 beeps, NOT THE RAM

thanks alex. I'm going to the genius bar later this week for them to get a look at the issue.
in the meantime, do you have any idea why the problem occurs when I apply a little pressure to the bottom of the computer (under the command screen). here is a video of the situation: https://www.youtube.com/watch?v=88C34bHZAd8&feature=youtu.be
also, i found this thread describing my exact situation: Field of vertical lines all over Macbook Pro screen? (+ freezes, beeps)
do you have any idea of a solution from reading that?

Thin Purple line on screen MBP 15"

Recently a thin purple line appeared the right side of my 15" macbook pro screen. The Line goes from the top of the screen all the way to the bottom......I purchased my Macbook pro about a year ago brand new. Has anyone else heard of this problem? I tired to take a screen grab and it doesn't appear in the screen grab picture

hi, all
your graphical probleme have got a good case in France, difficult for me to translate it, but It was solved, and Apple have changed the faulty material
in another way, but there is a few lucks that it came from it, according to your symptoms:
check if your graphic card is a ATI radeon X 1600
if yes, check the others discussions about it here, and also, use smcfancontrol to speed up your fans until the temperature goes under 65 ° C .
look if you have the same lines... run extensive graphicals programs, check temperature, prevent it to go above 65 /69 °
wait a bit
now, reset smcfancontrols to default, but don't leave it, to be abble to watch the temperature and do the same activity
if your line come again, you have quite an answer..

Satellite U400-22n and Win7 - screen hangs after 5 min

Hi, This is my first post
Ive purchased a new U400 with Vista preinstalled, last week ; 2 days ago Ive upgraded to windows 7 32bit professional when I stared Installing it windows prompted me that it requires a full installation , so I done a normal full install, windows 7 installed normally .
Now my screen hangs after 5 min and windows gos black and reboots after 3-5 min, Ive downloaded all the drivers from the Toshiba site Ive used the auto detect, and installed the drivers one by one and tested if the reboot stops , Ive reinstalled windows now 4-5 time returned my copy to the shop and got a new copy of the windows DVD, its the same,
Please has some one any advice for me. As the shop Ive perched this from will not upgrade to windows 7 for me.

hi Mather,
any bluescreens visible?
win7 32bit i guess...
you have to install all the drivers for win7 provided by toshiba in the right order!
first chipset and patchfiles if available...
i think a clean install will do the job!
make sure that the hdd is error free!
you can upgrade from vista 32bit to win7 32bit
but no chance to upgrade to a win7 64bit when a vista 32bit is installed...

Toshiba Satellite Pro P100-465 17" screen.

My Tosh has a vertical 30cm white band 90cm from the right hand side of the screen, the background is normal. If I use an external monitor the picture is ok. I have fitted a new screen, and it is just backlit, putting my old screen back the fault is the same, I’ve refitted the connections to the screen and p.c.b board by the LH hinge, no change. I sent the new screen back and they said it tested ok, so I suspect the wiring! Any other advice would be appreciated.
Solved!
Go to Solution.

I have recently bought and fitted a used/tested cable and inverter and the old screen work ok but still has the vertcal white band on the screen. External monitor fine.
Any ideas, but I still suspect the screen.

Wireless connection is not working on my Satellite U400/03S

Hi Guys,
I have Toshiba Satellite U400/03S laptop and I have a very strange problem that I can't seem to get around.
I signed up new ADSL2+ connection and yesterday when was I trying to setup it up I found the I can connect to internet through wired but not wireless.
The laptop shows the network in the list with full signal strength. I have configured the connection properties identical to my laptops including the WEP key and such. When I go to connect to the network, it just sits and says "Waiting for network" for approximately 5 mins, then that dialog dissapears and never connects to the network, just goes back to the network selection screen.
Has anyone had this problem? If so how did you go about fixing it? This is very frustrating and have been playing with router options and computer options for hours now trying to get it to work properly with no luck.
Just to let you know guys that I am using Billion BiPAC 5200G RC wireless router and windows XP pro on my laptop.
Help please! Thanks in advance to all that reply.
Sam

Hi buddy,
I agree with Macius. You should contact your internet provider because I think its a problem with your Internet connection or router that you get from them. So you can check with the guys step by step if everything is configured properly.
For creating a WLAN connection you have to configure the settings in router like encryption, MAC address filter, etc.
For testing I would disable all these security features.
Last but not least you should check the TCP/IP configuration of your WLAN card. Maybe you need a static IP address or DHCP Depending on your router ;)

Satellite U400 will not usually boot up

Hi all,
I have a Toshiba Satellite U400-217 (PSU44E) running Windows 8.
Worked fine until a week ago. Now, when I switch it on, the indicator lights light up, there is a brief hard drive spin (1 second) - and then nothing. The lights above the keyboard stay lit, but the screen stays black.
I read a reset remedy where you take the battery and power cable out and hold the power button for 30 seconds, then plug the power cable back in, boot up, shut down, reinsert battery and boot up again.
However, the machine will still not boot up after the 30-second button hold. I still just get the lights and nothing else.
However, the machine will generally boot up fine on one attempt out of every 30 or so.
It's annoying - any ideas or suggestions very gratefully received.
Many thanks,
KaiBosh

> However, the machine will generally boot up fine on one attempt out of every 30 or so.
In my opinion you should firstly check the HDD
A friend of mine installed Win 8 on new notebook from another manufacturer
After some time the notebook could not boot up I thought its something wrong with motherboard but finally it was just an HDD malfunction
To be honest I dont know if its only HDD issue but in my opinion the HDD is one of the first parts which should be checked
Ok, in worst case it could be possible that mobo malfunctions.

Satellite U400-135 overheats

Hi,
Few weeks back I bought new Toshiba Satellite U400-138 and now I feel it is an inferior design due to many complains I found either here in the support forum or from the people who tried to deal with this series .
Fist of all the overheat issue becomes not affordable as I all about to loose my fingers due to extreme heat comes from the touch pad bottom level !! moreover it usually takes more than 7 minutes to get the windows logon screen while starting up the windows and when you access the windows it keeps showing CPU usage almost 100% for long time just by clicking the internet explorer so i can not do any thing except waiting (it is killing slow) and when i compare it with my old P4 desktop i feel how much i was wrong when i decided to go for the U-400 !
Today I am decided to take the laptop back to local Toshiba dealer and when I was there I tried to touch the lower part of the similar model availbel in the show room and it was extremely hot and when I asked the sales man there he informed me that there are many customers reported the same complain then I have been referred to their service center for inspection and I am so boring now because my new laptop will be serviced after just two weeks only and , I think this model is an inferior design and the only way to get rid of this problem to get the same replaced by something else?!!!!!
your valuable feedback is highly apprciated.

Hi Will
Ive got a U400 too. Its a U400 which belongs to the PSU40E series.
I use both OS; Vista and XP.
At the beginning the Vista started slowly it was not too slow but slower as the Win XP.
I investigated a little bit and found a solution;
Firstly I found out that many background processes and applications have been loaded at the beginning of the booting procedure In MSCONFIG you can find these applications.
I have disabled some not necessary (for me) programs and the notebook booted much faster.
Furthermore I have noticed that Tempro tool update helped a lot.
So please check these both proposals.
I'm sure it would help you...
Regarding the higher touchpad temperature;
Well, my touchpad is also warmer as the rest of the notebook cover but this is nothing unusual because the cooling modules are placed below this touchpad and the left hand side is always warmer due to the heat dissipation on this notebook side
So you shouldnt be worried; this is nothing unusual
Bye & have a nice day

Re: Satellite U400-11Q with Vista has new HDD but no recovery disk

Hi,
Before I start a very important message: I usually don't work with pc...:-) At my work we have an IT-department for our PC's :-))
However, now I have to work privately with a PC/ notebook and I need help: I am sitting in front of a Toshiba Satellite U400-11Q with a completely newly formatted HDD and unfortunately with NO recovery CD or DVD whatsoever !!
So far I have managed to format the HDD aagain and to put a WindowsVista Home Basic (OEM Software) from my old pc onto this notebook. However, nothing works yet ( I want to get into the Internet etc.)
Therefore I now need to put on all relevant drivers as well as the original TOSHIBA drivers, right ?
How do I do this ? Which drivers to I need ? Do I need to download all relevant drivers (totally 113) one by one from the Toshiba website ?
ANY help is appreciated as I can see myself spending the whole night in front of this PC..
Thanks,
M

Hi Dr.Lamp,
thanks for helping me with listing the drivers as well as giving me a recommendation on the use of Windows 7.
Re Windows 7, unfortunately I only have a "free" VISTA Home Basic at home and therefore I have used this operating system for tonight ! I want to get this PC/ machine running as well as possible as quickly as possible...just unfortunate that its a PC with the need of "thousands of drivers"...
If anyone in cyberspace is interested in reading about my HUGE problems with simply setting up a computer newly, I can at this point simply recommend to you PC fanatics:
Please do put onto the internet decent driver packages to download for somebody like me in a bulk !!! why make life so difficult ? How the hell will I get the right order of driver packages ( which you are listing) on to this PC if I have:
- no idea where to find the drivers you mention ( I have to google every single one of them)
- I have already bought a "recovery DVD from Toshiba, but which takes up to 14 days to arrive and costs about 36 EUR
- I just want to get the computer up and running properly with all licenses legally acquired !
So here I am after about 12 hours of woring on this thing as a newbe:
I have so far this evening managed to firstly install a network driver ( I also had an old VISTA resource DVD at hand) after somehow installing some "recommended network drivers" ( by this recovery DD).
This way I managed to get the wireless LAN connection up and running which is a huge success, because I can now download drivers form INTERNET directly onto the computer.
Currently there is an installation running of Windows VISTA including about 120 updates for this VISTA, so I am busy on these updates...I am nowhere close to the 50% installed mark so I probably will have to get some sleep now and continue tomorrow with you list as well as finding your drivers and installing them in the right order ! What a drag ?! Well, somehow these PC's just cost you TONS of TIME..
Anyway thanks for you help and if you can give me a hint on a shortcut, I would be very happy to hear about it.
Thanks
J(M)

Satellite U400-12P - Multimedia Shortcut Keys illuminates 24-7

Hey everyone,
I am new to this forum and I hope someone will solve the problem I have.
I own a Toshiba Satellite U400-12P (been a year now). Past few days I have noticed that the multimedia keys (PLAY/PAUSE/FFD/RWD/) isn't functiong (doesnt respond to my touch) + multimedia keys illuminates 24-7;that is even if the computer is switched off the shortcut keys are shining brightly. I have no clue why this is taking place.
If someone has a solution to this. I shall greatly appreciate it.
Thanx

but unfortunately the keys and even the word satellite and the light over the mouse are not lightning even though the ,mutimedia keys are working normally,
would you please support me how to light these keys again?
Thanks.

Satellite U400 - the webcam does not work anymore

Hello guys here is my sudden probloema!
About a year ago I purchased a laptop
TOSHIBA - Satellite U400
with s.o. WinVista 32bit and with integrated webcam chicony etc. ....
For a year, everything worked correctly, but for some days now, the webcam does not work anymore.
As soon as I try to open it, a message of management software cam that says "Webcam driver open fail, please restart or computer room"
I tried to do it all: aggioronato and downloaded the drivers from toshiba, uninstalled the program and re installed the webcam ....! updated bios notebook ....! useless!
the strange thing .. well that going into device manager ... the webcam is not there ....! but if the launch seems to open just then check quell caz ... Warning!!
Gan you help me?
Graziee

Are you familiar and comfortable with LINUX LIVE bootable discs to load an alternative operating system with unobtrusive but extensive Toshiba device support so you can determine if your webcam hardware is ruined or if the problem is software and possibly solved reinstalling Windows ?
At this point, you're pondering less time consuming but more expensive choices such as buying another web cam, or another computer and you might be temporarily borrowing someone else's web cam / using a non preferred spare web cam that isn't optimal for your needs.
Continuously downloading software, registry cleaners, and repeatedly reinstalling drivers will eventually ruin your Windows installation and consume more time than you've wasted so far and still doesn't guarantee to fix your malfunction.

Satellite U400 - loud noise coming from cooling modules

Hi,
have bought few month's ago Toshiba Satellite U400 and everything was perfect and i just bought it because i do not like sounds.
When i surf on the net i like it to be quite, but these last 5 days it has started to sound.
Toshiba U400 works and it takes out to much "Air" from the side and just sound all the time, even if i open IE or MSN or anything, and before it just did sometime but now it does often.
Please help me because this is very annoying and it sounds to much, and i do not like it, why has this start to happend now and not before? and what can i do about it?
thnx.

Hi
This is worth checking. I had a similar problem myself and I noticed that on my wife's profile the fan's behaved but on my profile the fans went crazy.
I did some digging and noticed through Task Manager that a particular process was using an aweful lot of CPU. I did some more digging on the process and discovered it was the Bluetooth driver. I checked in the system tray and sure enough Bluetooth was active. So I logged onto my wife's profile and on her's, Bluetooth was disabled.
So I went back into my profile, disbaled the bluetooth, right click on the Bluetooth icon in the system tray and select disable. All nice and quiet again.
It's worth a try.

Satellite U400-11U - no sound when using headphone

Hi everybody .
i has get a Toshiba Satellite U400 (u400-11u) with Vista installed and at the first use all work nice and i have never tried the headphone, but after sometimes, when I put on the connecteur on the jack of headphone there is no sound, only when I put off the connecteur out of jack, the speaker work.
I has learn that I must update my BIOS and I doing it : no solution, there is no sound, so I have change to XP SP3 the some problem and now I'm with Windows 7 with the some problem.
So if you have any information about this problem, please give'it to me !!
I have tried all solution in FAQ, but no way !!
PS : sorry for language mistakes !!

Unfortunately I cannot offer you 100% working solution because I don't have exact the same notebook model but what I can say is that I think BIOS has nothing to with this issue.
It is very interesting that you have tested it with different operating systems and different headphones but the situation is always the same. What can be the problem?
At the end I believe this port is somehow defective. I have three different laptops here on the desk and hear internet radio almost all day. When I use my headset with all three laptops the reaction is always the same. Internal speakers will be disabled and I can hear music on my headset.
Maybe you should contact nearest authorized service provider and ask for help. Let them check the port.
One more thing: when you start notebook for the first time (factory settings) everything must works properly. If you have noticed this issue from that moment I really think there is a hardware problem.

Satellite U400 running little slower now

My laptop Toshiba Satellite U400 running little slow and maybe because i have old drivers for:
*Mobile Intel (R) 45 Express Chipset Series Processor to DRAM Controller - 2A40
Yes because it shows i have version for this: 8.7.0.1007* but the *NEW version* *is: 9.1.1.1012*
Where can i get these new drivers please?
bcz as i said earlier my laptop is runing little slower now.
Thanks.

No smart Paolo, i dont know about smart but now this is second time i tell you, its not the same question it's not about the same driver even.
Read carefuly and you'll see.
It doesnt seem you can help people so good, so plz if you can't help and HAVE NOT knowledge and are not good at PC-solution then it's better to not post at all.... Because if i have followed your help maybe my laptop now would be destroyed, since you said i had wrong drivers for my Graphic Card, i was close to follow your instructions and to mess up and maybe even destroy by uninstalling and installing drivers, because Graphics are senestive now , but i am glad i did not follow your Instructions Paolo30.
*Anyone that know about this issue ? where to get latest drivers for Mobile Intel (R) 45 Express Chipset Series Processor to DRAM Controller - 2A40 ?*

Satellite U400-10J - power is on but NO LCD dsiplay

Good day.
I have a new Toshiba Satellite U400-10J.
I did not turn it off after i use it and then when i get back it was hanged up so i decided to turn it off by pressing the power button in few seconds.
The next day when i decided to use my laptop again something occured that i don't understand.
My problem is;
When i turned ON the power button, the laptop runs but there was no display, i checked the fan and it runs for a while then stops after a few seconds. All other button has lights and the CD drive is running too.
What wonders me is that the hard disk led is not blinking or there's no light in it and why there was no LCD display?
Please, anyone can help me on this matter. I would really appreciate if you can give me your answer now.
Thank you very much.

To be honest I dont understand why this happened. Im owner of Satellite U400-10N and something like that never happened to me.
However, I read about some useful workarounds which could help you.
First of all remove the battery and disconnect the AC adaptor.
Then you have to wait Im not quite sure how long but I would recommend waiting for about 30-60min.
Then connect both devices and try to power up the notebook.
Check if this helps.
Bye and good luck
