• spectrex360: Start button / stop / flashing laptop won't turn on

  I just got the HP spectrum x 360 on the Store of MS (signature edition). The power button on the side flashes and it won't turn. I know that the battery is charged, because it is connected and there is a connedtion that the led is lit when the power cord is connedted to the laptop. But the power button continues to blink and I can't turn on the computer. I tried to tap on the screen and the Microsoft keyboard key. Any way to reset this? Thank you

  OK, I found the answer. It was a hard reset. Just hold the Start button for 20 seconds (or until it no longer flashes) then wait a bit and you can restart the laptop.

• Laptop does not turn on but the power button is on ip

  I just bought my HP Pavilion 360 less than a month ago and it's been used for research and schoolwork. No virus or threats have been detected. It was working fine today until I had to load it. When it was fully charged, I turned it on and the screen just frozen. I tried to shut down by pressing the power button, but it did not work. Now, to just black screen but the power button turned on (meaning it's on). What should I do?

  1. don't remove the battery from your laptop

  2. just to unplug the AC power from the laptop adapter

  3. press and hold the power button on your laptop for 1 minute

  AFAIK, this should make the difference

  The indicator disk HARD is not Flash or anything... (in case that helps)
  I also tried to remove the battery, hold the power button for 30 seconds and then reconnect the power cord... Same laptop turns on but the screen is black.

  I tried to connect my laptop to my PC using a HDMI cable screen, but without success... Laptop turned on but monitor my pc showed nothing.

  I have not changed anything inside my computer laptop or unscrewed it.

  PS:
  Quite often, I kept my laptop on the bed/pillow it may have something to do with overheating or something.

  How did I get to this point:

  Yesterday, my laptop was fine, there was nothing wrong with her... I turned off during the night, but when I tried to turn it on this morning it is where I have faced this problem.

  Any help would be appreciated.

  Thank you very much

  Long ago, I had similar problem on my old Satellite. CPU was faulty. After replacing the CPU, everything was OK again.

  Maybe you should contact Toshiba and let check your laptop. They have diagnostic tools and may know what is the problem.

  What do you think?

• 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.

• Laptop screen turns off but the system never sleeps when closed.

  Hello!

  I have a laptop Alienware M14x and quite frequently when I close my laptop, the screen turns off but the system will not. When I reopen it, the screen stays off and the system seems still to go but no matter what I press on, the screen does not turn. To fix it, I just turn it off power then back on the power button. I know that my laptop is still running because the fans are still running and the lights on the front and on the keyboard are lit. I don't know if this is a problem common or not, but it's really annoying.

  Any help would be greatly appreciated! If there are other details that might help, do not hesitate to ask!

  Thank you!

  -S.

  Firstly I find a windows command can tell you if you have something that prevents the mode 'sleep'. Run as administrator command window and use the command: powercfg-query.

  If you have my problem and SRVNET is active, you will see this:

  SYSTEM:
  [DRIVER] \FileSystem\srvnet
  An active remote client recently sent requests for this machine.

  2. to add SRVNET to the exempt list, do the following at the command prompt (EXACTLY as shown below.)  DRIVER MUST be written in capital letters):

  powercfg - requestsoverride DRIVER '\FileSystem\srvnet' system Awaymode

  and for good measure (not sure if necessary but I did anyway)...
  
  powercfg - requestsoverride DRIVER "srvnet' system Awaymode

  3. once all is said and done, it should look like this after you run:

  powercfg - requestsoverride

  [DRIVER]
  \FileSystem\srvnet SYSTEM AWAYMODE
  srvnet SYSTEM AWAYMODE

  4 enjoy again the "sleep mode".

• MacBook Pro 2015 turns on but the screen remains black...

  Hello

  Today, I tried to turn on my MacBook Pro, but my screen stays black. When I press the caps lock button, it turns green which I guess means he lit. I've also heard the startup chime it generally makes when you turn on. I already tried to turn it on and off several times and reset the SMC and the LANDAU... The screen is always black.

  Could someone help me please?

  Also a few minutes ago the fan has started to make noise in the macbook...

  But the screen remains black.

  Thank you

  Shaynidw

  Hi shaynidw,

  From your description, it seems that your MacBook Pro is powered, as soon as you hear the startup chime and see the light on the keyboard.  Thus, it seems that the problem may be with your screen or the video card.

  On the screens you see when you start your Mac

  Power on

  

  When you turn on your Mac, display is off (black) and you hear a startup chime. Your Mac Initializes his BootROM and memory (RAM live). It then performs a power - on that self test (POST) and a test of BootROM. If you hear beeps or chimes at this stage, this indicates a possible hardware problem and start stops. If you add memory to your Mac, check that it is installed correctly.

  White screen

  

  After that only walking self-test is completed, your Mac sends a video signal to your connected screens. The screen may appear black or grey at this point in the boot sequence and backlight of the screen should light up. If you do not see the image appears on your screen after a few moments, try increasing the brightness of your screen. If you use an external monitor, make sure it is properly connected and turned on.

  shaynidw, if set up the brightness of your screen does not help, you have an external display (computer screen or TV) that you can attach to your MacBook Pro to test?

  In addition, you can try to start your computer in safe mode to see if you get different results.

  Try safe mode if your Mac does not end commissioning

  If the problem persists, you may need to take your computer to an Apple Store or service provider authorized Apple , so they can inspect the video card and cables to isolate the problem.

  Take care.

• Laptop turn on but the screen is completely black

  Hi guys,.

  I was wondering if someone have an idea as to why my laptop (which was working perfectly last night), now has a black screen when I try to turn it on.
  I read in some other forums who offered to take out the battery and hold the power button, but that didn't work...

  Remedies?
  Thank you.
  Jess.

  Hi Jess

  Is a busy HARD disk when you start your laptop?
  You hear Windows sound?

  If possible try to connect your laptop to the external screen or a TV to see if you can see anything on an external device.
