• Satellite Pro L300-21F does not start and the screen remains blank

  L300-21F is aged 18 months, so out of warranty. When you press the power button, you can hear the fan and a "click" but the hard drive does not start and the screen remains blank. The power and the battery on the headlight LEDs, but the switch light does not work. I checked the power supply and it is 19.3V and substituted a good known. Removed the battery, tried with just the power cord and still nothing. Pressing ESC or F2 when you press the button power does not bring to the top of the screen of the bios or any other message. I have concluded there is no power the jury. A friend he had its technology take a look and he concluded Council is probably a friend.

  1. He's probably right?

  Hello

  If it's a motherboard problem, the whole motherboard is replaced. Quite expensive part...

• Qosmio X 770 turns on but the screen remains blank

  So my Qosmio X 770 turns on but the screen remains blank, it was randomly turning every so often, but now it is just blank.

  The hd works fine again, I tried to plug it into a TV to see if it works, but no signal is found. I was informed by a friend that it could be a problem with the graphics card, I wonder if it can simply be exchanged if I buy a new one or if he joined, and I have to replace the whole motherboard?

  Any help would be appreciated.

  Even if the HARD drive is faulty, the laptop should be able to IT and you should see the home Toshiba on the internal display screen.
  If its definitely NOT drive HARD problem.

  You said that you have connected the laptop to the TV. You see the start of Toshiba on the external monitor (TV) screen? Are you able to access the BIOS by pressing F2?

  If this is not the case, there is certainly a hardware problem.
  It could be a fault of memory modules, graphics card or the same motherboard malfunction could be possible.

  GPU problems or the motherboard, the whole motherboard must be replaced and that's expensive fix because mobo belongs more expensive laptop.

• HP Envy 15 "touch screen power LED appears, but the fans does not and the screen does not light

  Hello!

  I'm a student in computer engineering at the University of Waterloo 1A, and I run a very serious problem with my HP Envy 15 "TouchSmart laptop computer running Windows 8.1. It is a problem that just started today, and I'd rather have a first support here before going to see the technical support Office sometimes tomorrow. It has to do with the screen and the fans where the Power LED lights in white, just as when the laptop works properly.

  (I have warranty on the laptop when it was purchased last June, except that if I find that I need to get a replacement, I'll lose all my work, I did on that since I started my semester.) It's so silly of me not to have all my work saved on a backup, because I have an external hard drive. Problem is, I've had too many problems in getting myself organized, I'm not being open-minded as I should, and worse, I'm not a balance between life and work at home.)

  Before I had my MATH 117 conference (Calculus 1 Engineering), I was in a nearby lab where my laptop was open and turned, works correctly. I've had NetBeans IDE running since I wanted to work on the second part of my current assignment of CS 137 (principles of programming). Because it was almost time for my presentation, I closed the laptop by simply moving the screen down on the keyboard, where it goes into mode 'sleep'. (Whenever I flip to the top of the screen, the laptop is supposed to return, and the sliding screen of Windows 8.1 connection will appear.)

  When I took my seat for reading, I wanted to spend a little time to work on my programming assignment. However, after the reversal of the screen to the top, instead of having the login screen appears, I encountered the problem: the power supply light is showing a white light, but I don't hear the fans between the ventilation openings on the left side of the laptop and the screen does not light. I tried to take the power for several seconds and once button at least 10 seconds, except that the power light continues to display on a white light. The Commission of the Wi - Fi light is not displayed.

  Whatever it is, I don't want to take out the battery because I have that on my last laptop, and it's from there that I couldn't turn to the former, a new market. If I leave the Envy laptop battery, it will short-circuit the connections between the battery and the computer, and so several components will FRY. For now, what I do let the laptop is to empty the load on the battery. Then, once I noticed that the power light does not project a white light, or plug in the AC adapter and try turning the laptop on the power button.

  It will take a little while for the circuit drain the load on my battery but...

  Anyway, please would you be kind enough to help me with this problem? I would really appreciate if you can give me several recommendations. Thank you!

• Satellite L405D-11V - freezes and the screen goes black when you watch the video

  OK, so I have the Toshiba Satellite L405D-11V, I had a breakdown, basically, the computer freezes at any time and the screen would go black, with the fan and lights still ongoing, this could be at the start, or a few hours using the laptop, so I decided to ring Toshiba technology support and they arranged for my laptop to collect and be expelled for repairs.

  I was able to track repairs online via the tracking service and was able to see what they were doing to my laptop, he said that they have ordered a part, it was underway and the repairs are completed.

  However, I got the laptop back today, I turn it on, all right, I start using the cell phone that everything is fine, so I decide to watch a video on youtube, and it freezes again, so I turned off now pressed the power button, hoping he wasn't that a large, I turn back to and load the video once again it freezes and the screen goes black again, after that whenever I am watching a video or a game, it causes the computer to crash and freeze as before the repairs. So there is always a mistake, but I'm not sure what to do

  Its still under warranty, I bought the laptop from the Comet, but I really don't want to send the laptop for repairs again and find it comes back with the same fault, is it interesting sending distributed, maybe see if the comet will replace the laptop as its still less than a year to buy the laptop, or it'll just be useful to save all the hassle and buy a new laptop? If this fault happened to someone else, I could use you some help, and if someone could shed some light regarding what could be bad?

  Thank you

  Hey Buddy,

  You changed something on the configuration after you got your notebook back from repair? You update a driver, or something else?
  What operating system you use on your L405D satellite?

  To be honest it is really hard to say why it happens because technicians test to check if your laptop is running correctly.

  In my opinion you should try to update the display driver. Maybe it's the origin of the problem of s
  If this isn't the case, I recommend installing Windows from Toshiba Recovery disk to restore to factory settings. These parameters are pre-tested by Toshiba and should work.

  If you still have the problem, you must contact the technicians again. I mean you could track the online repair and according to your assignment, everything worked well during repair, so in my opinion he should t be a problem to contact guys exactly.
  Explain your very detailed problem. I think that everything can be clarified then. :)

• HP Pavilion g7-1261nr turns on but the screen remains blank

  I turned on my HP Pavilion g7-1261nr the other day, and the fan ran hard, as well as the caps lock and number lock LED flashes once every two seconds. The screen remains blank during the process. Could someone help me with this problem please?

  PcMatic I invite you to read the links provided, because they are there to help.

  If you entered my link, you would have seen this:

  Caps Lock/Num Lock LED component tested error Condition

  LED flashes 1 time CPU CPU not functional

  2 times for BIOS BIOS corruption failure LEDs blinking

  LED flashes 3 times non-functional Memory Module error

  LED flashes 4 times Graphics Graphics controller not functional

  Map of 5 times the system board failure system general LEDs flashing

  Authentication failed for the BIOS BIOS 6 times blinking of the LEDs

  According to the times that they blink, of what I mean, it's once and then a pause. Which would indicate that the CPU is broken.

  Only a repair can fix that.

• Portege M200: the screen is blank when you switch to Tablet mode

  Hello.

  Have a problem with my Portege M200 and after hours of searching for a solution, I'm still at a complete loss as to how to fix it.

  Essentially, when you attempt to switch to Tablet mode - or if I press the button cover closed 'sensor' on the far right, which is essentially the same thing: the screen goes black.

  This means that I can not in tablet mode at all.

  What happens across multiple operating systems and will happen even before that an operating system has started. Of course, I checked that when in Windows, the option "When I close the lid" is set to do nothing and I even checked for any cable setting in bios but saw nothing relevant.

  As far as I know this has only started happening since I sent it for repair with toshiba a month or two back (motherboard has been replaced I think).

  No way to control it via software or am I'm going to have to send it for repair again?

  > Like as far as I know that this has only started happening since I sent for repair with Toshiba a couple months back (motherboard has been replaced I think). Anyway to control this via software or am I'm going to have to send it for repair again?

  You description, it looks more like a hardware problem as a problem of software because this happens before an operating system has started. That's why I would exclude a software problem.

  In your case I would recommend you to contact the ASP again and explain the whole situation with your laptop.

  Good luck

• Randomly, the screen is blank when the charger is connected; generally very well during the execution of a battery

  We have a Dell Inspiron 6400 laptop.  When the charger is connected the screen will become black suddenly, and you can't seem to get the screen goes again.  It does not seem to close completely because when I press the power button twice (or more?) it brings back me to the password screen.

  This only occurs when you run the battery, IE. not connected charger.  I bought a new charger thinking that was the problem, but the same thing with the new charger.

  My only thought is that it could be the battery but unwilling to spend £60 on a new if it does not solve the problem.  And also the battery OK charges when the laptop is not activated.

  Help needed please!  Thank you very much.

  Hi Tiffany - Sorry a very very late thank you for your help on this.

  I've been very busy and have therefore been put off watching it.  We have been surviving off the battery and when he runs out to paralyze the system / sleep mode and reload.  It became quite frustrating and that's why I've decided that I really need to fix this problem.

  As you the advised, I went just through the safe mode and the problem occurred again glancing at your advice it seems there must be a hardware problem.  I had originally bought a spare power outlet, and this does not work then maybe it's the battery.  As you suggested, maybe a qualified support store is the best solution now.

  Thank you once more!  I am very grateful.
