  Hello

  First of all, regarding the manual of maintenance on the link below--remove and reposition your bars of memory.

  If the above makes no difference try the following.

  Again, regards to the manual on the link below, delete one of your modules from memory and then see if the computer will start.  If it doesn't, try the same module, but in another location.  If it is still won't start, try the other memory module in both slots, to see if any combination will allow the laptop to boot up normally.

  The procedure for withdrawal of these modules is detailed from Page 63 of your & Maintenance Guide.

  Kind regards

• Lenovo black screen randomly Y50-70 times

  Hi everyone I have a very strange problem with my laptop. Here's the Specs (copy-pasted from amazon because I'm lazy):

  Lenovo Y50-70 39.6 cm (15.6 Zoll UHD IPS)
  Intel Core i7-4710HQ, 3.5 GHz
  12 GB OF RAM
  Hybrid SSHD 1 TB (8GB) NVIDIA GeForce GTX 860 M / 4GB

  Since I bought it (about 1 1/2 months of passes) after I installed Windows 8.1 and improved to 10 I sometimes get a black screen, no cursor as has happened repeatedly after upgrading to w10, always helped restart and everything was brilliant.

  The thing is that my screen will not turn off, it's all black, but always on (visible by the light light is always built). It started to happen very rare, perhaps after a week or so, but today I get the problem constantly with different models:

  through normal startup:

  -Start-up of the PC-> black screen

  -Start-up of the PC-> "LENOVO" appears-> black screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> black screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> welcome-> black screen screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> the Welcome screen->-> connection-> black screen

  -Start-up of the PC-> "LENOVO" appears-> Windows load-> the Welcome screen->-> connection-> after a random time: you guessed it - black screen

  The list is repeated several times today which made me crazy enough then and now, also restart does not power more...

  The same phenomenon occurs during Advanced Start (the small button to the left of the power button), even when I asked for a Startup Recovery. It works well is that during safe mode.

  I tried several things, such as the removal of the Intel graphic card, which gave me access to the normal mode of the system. Here I have updated the BIOS to 3.0.3. Now, I'm testing the Nvidia Driver (relocation etc.). Interestingly, I have observed a disturbing "PnP-screen (standard)" which had a yellow flag next to it in Device Manager, although no second monitor is plugged into the machine. Maybe it's the a boring me severa hours today.

  Also, I am plugged to my TV right now which helps me get at least a photo. During this State, there are also 2 'pnp front (standard)' listed in the Device Manager, none of them with the flag...

  Guys do you know something about this problem, anyone has stumbled across it too much and THE TIPP to save me and my sanity?

  Kay, gentlemen.

  After calling amazon (seller) and Lenovo and "help" from a friend, I decided to return to win8.1. I reinstalled the drivers, settled everything back the way I needed her, saved our day by finding our Starbound universe still exists and! No black screens no more. It seems that this unit has still some problems with the operating system most recent Microsofts then Yes, I'll wait... even though I liked 10... :/

  Cases can be considered resolved and thanks for everything the world where with me on this quest. Cheers on you guys!

  Hello

  Please download CCleaner here and when it is installed, open it, appointment on the 'clean' tab, leave all the boxes even and click run while cleaning.

  When you have done this, go to the 'Tools' tab, select uninstall and bottom right, select Save to text file, select a file name for it, and then open the saved document. Send the contents of it in your next reply.

  It is possible that it is caused by corrupted files. You can try to run the System File Check to check (and challenge!) corrupted files.

  Use the System File Checker tool to repair missing or corrupted system files.
  https://support.Microsoft.com/kb/929833?WA=wsignin1.0

  You can also have a third-party application installed on your computer that is the cause, so try to perform a clean boot Mode, which is executed at Windows startup, by using a minimal set of drivers and startup programs.

• Portege M400: Black screen from time to time

  Hello!

  I have a little problem with my Portege M400 Tablet PC. The laptop runs great most of the time. Unfortunately, from time to time, the screen goes all black - or to be more precise, the screen shows up again. In most cases, the display has been disabled by my energy saving profile, and when I try to put the screen back on (for example by moving the slider or press any key, just like usual), the screen remains black. I see that the computer works and I can for example hibernate the computer, but even after waking up, the screen is always black. Also, it does not help to change the power profile or output or anything - the screen remains like that until I restart the computer.

  I have the new bios 1.80 (because of the better fan control) and I updated the Intel chipset drivers already (I've had the problem before, so it is not the update of drivers). Any idea that he might be, perhaps the bios (it was the first thing I installed after the purchase of the laptop I knew before the fan will be strong otherwise).
