  "Problems of upgrading Windows 10: black screen after update (new).
  Some users taking advantage of the Windows 10 upgrade are the conclusion that once the completed upgrade their device just gives them a black screen and does not start.
  Microsoft is still working on a fix for this, but it's not a way to avoid it now. Worse, it seems that the problem that happens on multiple PC configurations. For now, we can only suggest using the utilities provided with your backup device and create some external media backup before starting the upgrade in case that happens. If this happens and you live near a Microsoft Store, make an appointment with them to have your device looking if you experience the problem. Some reports (such as those of our comments) indicate that disabling anti-virus programs before performing the upgrade prevents this issue. »

• Black screen on startup, caps lock flashing - Compaq Presario CQ57 311SO

  I got this computer from a friend who owns a son.

  We do not know how or when it appeared first, but it's in this State for a few months now.

  It is a Compaq Presario CQ57-311SO and its a little more than 1 year, so store warranty has expired.

  What happens is that when you press the button power has nothing to display on the screen and you do not hear the sounds of typical start-up, the beep and the hard disk rotates upward.

  Instead of this, the Caps Lock key led flashes in the following model, 2 flashes pause 2 flashes.

  The computer is totally immune to any key, usb and cd entries.

  I tried the hard reset and memory sharing in different locations.

  But it seems that the bios itself is corrupt and failed.

  So my question is, can I Flash the bios somehow and make it work again?

  I tried a tutorial on how to do memory flash in FAT - 16 but no noticeable effect.

  Although the guide could be wrong or I could have done something wrong so I would really like to try again if I could get help with instructions from you nice people

  Thanks in advance.

  I solved the problem in dismembering the computer laptop everything and put back the battery CMOS.

  Thank you.

  Try a Hard Reset as follows.

  Shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery, connect the AC adapter and see if the laptop boots.

  If the above doesn't help, see if you can match the sequence of "Flashes" to those shown in the table below.

• Satellite Pro L450D black screen and will not respond to any keys

  Hello

  My niece has used his Toshiba L450D for almost a year now and he really liked it, who was until last month. She turned on her laptop and when she presses the button of the mouse, the button cracked and he fell into the laptop.

  Now my brother contacted Toshiba and I was told because it is under warranty it might return for repair because it was a common fault. Then he he packed in loads of air bubbles and a box to make sure it was safe.

  A few weeks later he came back repaired but we were all shocked that the laptop was put in a very loose box and you could hear this rattling noise. When we turned on the battery was flat and we had a new boot menu.

  As she installed it Windows 7 laptop would boot directly into Windows 7, but now after the repair of the laptop shows a menu black screen with as follows:

  + Windows 7 +.
  + Recover Windows to Factory Settings [active EMS] +.

  So we started in Windows and everything went well, but now after 5 or 10 or even 20 minutes, laptop displays a black screen and will not respond to keys or mouse movement. There is nothing on the screen its just black.

  I started in SafeMode (which was more difficult with the new menu) and it does the same thing. I even managed to do a virus scan quick who took 3-4 minutes and was clean.

  I would like some advice on what my niece is very angry, and it's difficult to explain what is happening to a child in the primary school.

  Any help would be grateful.

• Satego X 200-21 L - black screen and 3 beeps at startup

  Hello

  I have a problem when I turn on my computer (Satego X 200-21 L). I had a black screen and 3 don't beeps no boot up BIOS not nothing what do I do?

  Everyone everyone please help!

  Hello

  Looks like a hardware malfunction on your laptop, because normally these beep codes mean that it s something wrong with the hardware.

  Is that what you have installed extra RAM? If Yes, remove it and try to boot with original RAM only. Also try to reset the RAM in the slot.
  It work?

  In the worst cases, you must go to an authorized service provider. Technicians can check the laptop and determine the cause of this problem.

  Hello

  You mean that you are not able to access the BIOS?
  Have you tried to use the FN + F5 key combination to switch to view different devices? Select this check box. Maybe the output display has been switched to external monitor?  :|

  If nothing will not help to remove the battery and disconnect the portable AC.
  Wait for about 1 hour then reconnect both sides and try to turn on the laptop.

• Satellite A210 - 11 p - gos black screen and HARD drive does not

  Hello

  My Satellite A210 - 11 p suddenly goes to a black screen and the hard drive stops working. It is always under tension and if I want to restart I have to unplug the unit and remove the battery.

  I thought it was overheating and checked the time and they were really high in the 1980s. I took the fan and cleaned (very dusty) and the basic form of thermal paste. Temperatures plummeted now immediately but I still have the same problem, I updated the graphics driver and watched the temp on GPU (which is fine) but the problem is still happening. I used a number of programs to check for errors on the hard drive and no reported problems. I reloaded Windows 7 but still no joy.
  The problem seems to occur at any time and is not due to the execution of a given program, even just browsing with firefox

  Not too sure what to do and any advice would be welcome.

  Hey Buddy,

  > I reloaded Windows 7 but still no joy.
  Have you ever tried with Toshiba Recovery disk operating system?

  The Toshiba recovery disc there is an image of the settings from the factory with all the drivers and tools. If you install Windows on this disk, you factory back.

  That would mean if you have the same problem after the installation of recovery it s really bad hardware working because you have pretested settings of Toshiba. In this case an authorized service provider can help you make an accurate diagnosis what part is affected.

• After logging on my Satellite Pro only black screen and the cursor are visible

  I have a windows vista pro (PSAASE-00G004GR) satellite after turn on and typing the password for windows vista, the screen goes black but I see that the cursor moves & because it seems that the hard drive also works in th background, but I can't see anything except the mouse cursor , I tried to boor with other options (LAST WORK safe MODE KNOWN FEATURES... etc) but it's still the same only black screen and the cursor...

  I do not prefer the product cause of my data recovery on this subject, any ideas?
  thnx

  Hello

  You have the Satellite Pro A100 PSAAS hmm if you want to save your personal data, I recommend to remove the portable computer HARD drive and try connecting it to another computer via an external USB HDD controller. These cases of 2.5 HARD disk are not expensive and you can buy it in every store of the computer.

  Then you could try to recover the laptop delivered together with the Toshiba Recovery CD.
  But wait; have you tried to connect the laptop to the external display?
  Check it!
  Maybe you could see something on the second screen.

  I think that this procedure could be useful to clarify what s wrong.
  To me this question looks like a small little dysfunction of the FL inverter.
  In this case the installation of the new operating system will help you not to solve this problem.

  But who knows the verification is necessary to find what could be wrong.

  Good luck and bye ;)

• Start black screen and beeps, HELP pls

  I have a HP Pavilion zv5410. When I turn it on it has a black screen and it beeps (1-2-2). I went on some sites about, but don't really understand what is happening.

  I put the new RAM in because that I was told by a techie, it was usually the RAM goes bad, but this did not help. I can't do anything with the BIOS because I can not even a screen to enter in info, even with an external monitor.

  Any ideas or suggestions. I'd appreciate any help.

  Thank you all,

• iPhone 6 alternating between the black screen and the Apple logo and nothing else

  my iPhone 6 alternates between a black screen and the Apple logo, what do I do?

  Hi Nathanielfromwa,

  If your iPhone 6 alternates between black screens and the Apple logo, this could be a problem that can be fixed by wiping your iPhone to factory settings. If this is the case, save your iPhone first. I've included links if you need help with backing up your iPhone, but also to reset to the factory settings.
