Qosmio G50-12F won't turn on

I got a Qosmio G50-12f
n : PQG55E-04C02YFR
The problem is: when I plug on the dc power I got a white light on the dc plug picture and a orange light on the battery picture.
When I want to power on the laptop, the white light turn off 1 second (maybe) and get back to initial position and the light of the battery turn off definitely.
I tried to find answers on the web. All I find is that maybe due to power: dc jack connector or power cable (the one which goes from the dc in jack to the motherboard or the battery power board under the mouse pad ..
Well Im lost
Anyone has answer? I want to repair it on my own.
Thank you

Hi
This does not look good dude
Im afraid that your motherboard could be faulty.
The battery indicator flashes orange because of charging.
If the battery indicator would be blue (or green), then this would mean that the battery is fully charged.
What you can do is to remove one of the memory modules and try to boot up the unit using one module in each slot
Sometimes faulty RAM prevent the notebook from booting.
However, such notebook symptoms are mostly related to serious hardware issues and it would be advisable to get in contact with an notebook technician who could test the hardware for malfunction

Qosmio DX735-D3660 won't turn on

Hi,
I bought a brand new Toshiba DX735-D3660 All In One from the States and got it sent to Australia, it arrived last night and I went to turn it on but it simply comes up with "PC" then "No Signal".
I have the Power Cord connected to an adapter as it says the input can handle up to 240V (AUS Output level). I had a tech guy come look at it today and he tested the Volts and they came up as 19V and then dropped out, he said the solution was to go and buy a new AC Adapter.
I did, and it still hasn't solved the problem.
The new AC Adapter has an output of 19V and a max of 7.5A, so it should be fine.
It is still coming up with "PC" then "No Signal", the power light is amber then flashes white once turned on then goes back to amber. There is no sound coming from the computer so it doesn't appear to be starting at all.
Any solutions would be great!
Thanks
Lach

Usually the AC adaptors are made for international usage, mean that the same AC adaptor should work world wide. The power input is mostly 100-240V
In some cases you will need a adapter to plug the power cord into the wall socket but this depends on the country or region
In your case it does not seems to be an AC adaptor issue since the power light flashes.
Possibly the hardware is affected so I think an technician should check this you could also call the dealer to get an replacement.
Good luck

Qosmio G50 won't finalize Windows 7 64-bit install

Hi everyone!
I recently wanted to updated my Qosmio G50-12f from vista 32bit to 7 ultimate 64bit. I did a clean install: formatted the c partition.
Everything seemed to work fine until the "setup is preparing your computer for first use" screen. At first I thought it just froze as it wouldn't go any further. Rebooting (in any modes) would get the same effect.
But to my great surprise and pleasure, it managed to pass that point when i desperately decided to wait long enough for a miracle to happen. But the problems still remain. The configuration process is just !REALLY! slow. I could painfully pass the firsts few screens, like enter computer's name, activation screen, security modes, but with a very long waiting time between each. And everytime it reaches this last security modes screen it would suddenly go to a BSOD:
Driver Power State Failure
* * * stop 0x0000009F (0x0000000000000003, 0xFFFFFA800193DD70, 0xFFFFF80000B9C518, 0xFFFFFA80029C8610)
Please anyone has any ideas about how to solve this?
Obviously it should be a driver problem, but how do i get to update any drivers without an OS running? I've seen such a feature in the repair section of the install DVD but it only accepts .inf files.
And I can t find those anywhere on toshiba's support website. Only .exe that you run from your already running OS.
Anyway the Qosmio G50 was not listed as incompatible with 7-64bit. So i'm a bit confused here!
Please Help^^

Hi
Fact is that notebooks are different from desktop PCs and many newer notebooks series are equipped with newer motherboards and controllers which need an additional driver.
The G50 needs an SATA driver in order to install the Windows OS.
The SATA driver should be a part of the Intel Matrix Storage Manager.
Some words regarding the ISO image.
Who knows what ISO image it is seem you are trying to install an image which was created on different computer this could be a problem on notebooks with different hardware configuration
You should use either the Toshiba Recovery disk or the clean Microsoft Windows CD!

After overheating my Qosmio X870 won't turn on

Hi guys
I need some help. I was playing a game on my Toshiba Qosmio X870 when it overheated, it had good ventilation and now it won't turn on, there's no battery light so I'm not sure if the AC power has blown, the battery has blown or something the the laptop has fried.
Can some one help please?
Thank you

Hi
In my opinion its hardware related problem.
Such hardware malfunction can be solved by Toshiba authorized service technician only.
I would recommend you to get in contact with Toshiba ASP available in your country in order to check the notebook and to replace the faulty part.

Qosmio G50 won't play certain disks

Hey
Recently my dvd drive in my Qosmio G50 won't play certain disks.
You can hear it attempting to then suddenly stopping and starting again. Others work fine but some just wont play.
I try them in other computers and it plays fine. So its not the disks.
Thanks for any help

Hi
This is nothing unusual and happens to all possible CD/DVD drives
I made the same experience with my CD/DVD drive.
What you could do is to check if an firmware update for your CD/DVD drive is available.
For that you should check the Toshiba European driver page the Qosmio G50 driver area.
Please check more info for details about supported CD/DVD drives
Otherwise I recommend using and testing different disks from different manufacturers.
My CD/DVD drive supports TDK and Verbatim but dont read other disks from other no-name manufacturer

Qosmio F60 won't turn on

Hi,
please forgive the simplicity of this question but I'm not that knowledgable with computers.
I have a qosmio f60 and it won't turn on. I'm not sure if the battery is flat/dead or if its the adaptor.
Only two icon lights are on on the actual laptop - the plug icon and the battery icon. I have tried plugging into different electricity sockets and also ensuring the leads are plugged into the adapter.
Any guidance would be appreciated. Thanks.

> This must mean the battery's dead right?
Start notebook and when OS is fully loaded put battery in place again. Is battery recognized properly? Will battery be loaded properly?
Load battery and try to start notebook with battery power supply only. Test it a bit.

Qosmio G50 802.11n activated but didn't work correctly

Hi
I get a new Qosmio G50 on christmas and now I have a little problem. I use a D-link draft-N access point and I want to use the 802.11n mode with my qosmio. But I have some problems with it. I activated the 802.11n mode in the device manager and channelbandwidth band 2.4 & 5.2 are both set on "auto"!! But I dont get the 300mbps, 60mbps is the most what I get. My father has a notebook from an other manufacture with also a 802.11n wireless card but not from Intel and with the other notebook I get the 300mbps! I can put the notebooks together in the same room, the other get 300mbps the qosmio fluctuates from 1 to 81mbps or so.
Do anybody know whats going wrong or do I have to change something at the device manager?? I heard that many other intel wifi 5100 owners also dont get the 300mbps speed.
can anybody help me??
greetz

Have you tried turning off 802.11g/b/a modes by setting it to "802.11n Only"?
Go to the Wireless LAN device settings in Device Manager to change these settings.
Remember that 300Mpbs is the signal speed. Actual data transfer speed (minus the overhead) is less than 100Mbps

Qosmio G50-129 PQG55E - 64Bit Windows 7 Upgraded - How To Update BIOS?

Hello,
I have a Qosmio G50 that I have upgraded to Windows 7 64bit. My BIOS is unupdated from 6 months ago when I bought the machine.
I went to update the BIOS just to keep things up to date, so I went through the online driver wizard:
http://eu.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp
And with all the above information inputted, it provides:
http://support1.toshiba-tro.de/tedd-files2/0/bios-20090312131718.zip
After unzipping and running P0060v210.exe, it extracts and then says:
" [Error] BIOS Update is not supported OS. Unsupported OS or service pack is installed. " (Word up to all my Googling friends!) "
Does Toshiba have a BIOS update for the Qosmio G50 that is supported on Windows 7? Specifically 64bit? They should fix this glitch that directs you to download this file when it clearly isn't supported by Windows 7.
Also, I tried to run it in compatibility mode with Windows XP SP2 and it ran fine -- but I was nervous about going through with the update if it originally doesn't support Windows 7, so I don't continue at the next prompt. Is it safe to do this? Has anyone else in this situation done it without issues? I've read that BIOS updates can go horribly wrong if not careful, so I'm hesitant to update the BIOS by running the updater in compatibility mode when it doesnt support Windows 7 on its own!
Thanks in advance for any assistance and Merry Xmas.

Hi All,
Sorry ,my English is not perfect.I have a Toshiba Qosmio G50-12K.The solution is go to the US Toshiba website.Here is the link:
http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=DL&os=&category=&moid=2140527& rpn=PQG55U&modelFilter=G55-Q805&selCategory=3&selFamily=804517
There are all of the BIOS what is available. The 2.1 BIOS exactly the same as on the European website just they used a zip file. If you guys open it you will find the same .exe file, the file size is the same, but don't use this one, instead of it you can find there an ISO file. Write a CD with this one, turn off the computer and boot from the CD, use the F12 button. This is a safety way update the BIOS. But I use the 2.3, this is newest one, for me this one is works much better, because the display is more bright. I hope this is a big help for you and you understand my English! :)

Qosmio X505-870 - Can't turn off and nothing on monitor

I wasn't doing anything particularly interesting when my computer just shuts off randomly. I pressed the power button to turn it back on, I can hear the fan and the machine going but nothing appears on the monitor. I pressed and held the power button to turn it back off and try again, it won't turn off. It's stuck with the computer on but a blank screen.
Not sure what to do, I can't turn it off, and it isn't doing anything.
Might try to put the recovery discs in to see if it does anything but I'm worried about files I have saved on the desktop (stupidly)

Hi colhyena,
I agree with Akuma. The same instructions posted by Akuma I found here:
[Which steps should be followed if your Toshiba notebook doesn't start?|http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=21]
So thats everything what you can do and if its not working you need professional help from an authorized service provider.
Qosmio X505 is newer notebook model so probably yours is still under warranty. In this case the repair is for free and you dont have to pay something. :)

K7N2 Delta ILSR won't turn off, just restarts

K7N2 Delta ILSR won't turn off, just restarts. Every time I click on "Turn off computer" in Windows XP, it shuts down, but restarts again. Could this be OS related, or perhaps Bios related. My other machine, almost identical to this one, except that the other machine has BIOS rev 7.6 and this one 7.2.

PSUs seem to be yr favorite subject, but I'm afraid this time it's software. I experimented some more as the problem only occured after installing the Nvidia drivers. Comparing the system settings in the device manager before installing drivers and after installing them, reveils that the problem shows up when AGP HOST TO PCI BRIDGE is installed. When killing this item the PC shuts off properly. Unfortunately when turning back on, Windows automatically reinstalls the PCI bridge and I have the problem again. LOOKS LIKE A MSI SOFTWARE PROBLEM !
By the way I have a PCI graphics board and not AGP in the failing PC (the good one has AGP graphics).
Now what?

[Help]iPhone 5s screen won't turn on / won't play sounds

Hello, my name is Bryan.
I've got a problem with my iPhone 5s. I opened my iPhone to fix an issue with the home button (Watched a guide on youtube on how to achieve this), and I connected everything as it is supposed to go, my home button is working but now my screen won't turn on or the phone won't play any sounds. I know the phone it's on because I can connect it to the computer and the computer recognizes it. Also, I tried calling it, and it rings on the phone I am calling from, but my iPhone simply won't play any sounds...
I am also sure the phone is not in DFU mode.
Any help?
Thanks in advance,
- Bryan

My iPhone 5 won't turn on, the screen just stays black!

My iPhone 5 won't turn on I have held the power button to see if it's dead or not and it doesn't seem to change the screen it just black I thought the battery could of died or something similar it only happened about 2 hours ago please help!

Hey Thermali,
Thanks for the question, and great troubleshooting so far. To completely isolate the issue, you may want to follow these steps:
Will not turn on, will not turn on unless connected to power, or unexpected power off
- Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- After at least 15 minutes, if:
               - The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
               - The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
               - Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
- If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
               - If the display turns on, go to step 4.
               - If the display remains black, go to next step.
- Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to
restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
