• T420 screen turns off and turn it back on when the AC adapter / CC is attached or removed

  You are working on your machine, staring at the screen and the power failure... Yes - something quite common in these parts of the world... but no worries, the screen darkens slightly according to the diet plan and you hardly notice. Then, when the backup generator kicks in and the power is activated again, the brightness of the screen is back to your usual setting. Meanwhile, it is not a gene. Right?

  Well, that's what should happen... except that most of the time it doesn't work! Most of the time, the screen turns off and then turns on remove the main power and reinstall it. Note that this never happened once with T61 or T41p.

  Initially, I assumed it was because I had an external monitor attached... maybe it was to reconfigure something there? But then, it happens even without the external monitor. Then, I tried looking for the video driver updates... maybe this bug had been fixed to the... no luck there.

  So, finally, after having known this more often now, I thought I would get feedback from you all. Any advice?

  Check the Intel Media profile with the power settings. If a battery is "Maximum economy" mode then it should be in Exchange for 50 Hz to 60 Hz... Change it to balance or maximum Performance and see if its ever-changing from 50 Hz to 60 Hz...

  If all else fails, try updating the video driver, it might be a bug in the previous version of the driver.

• 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".

• Inspiron 9300 screen turns off after the Windows Logo screen

  Inspiron 9300 my wife became severely infected.  I thought I had some weird things start popping up of the problem decided to wipe the hard drive and start over.  Unfortunately, I don't have to restore disks when I bought the computer.  I install windows xp pro service pack 2 full retail version.

  Installation was not a problem until I installed the driver ATI Mobility x 300.  I followed directions for installation from the website, do the installation of xp followed of the dell system software update followed of chipset followed video driver.  After that whenever I put on, the screen turns off after the Windows Logo.  The computer is still running and if I plug an external monitor everythng is fine.

  I tried all the troubleshooting tips I've seen in this forum.  I did a full install twice. made of safety boots (all right), started in VGA mode (works fine), I ran diagnostics from fn on startup, including express, extended and video tests and they pass all the controls.  I'm sure it's a software problem, but have been unable to solve.  I've updated the ATI bios although when I run it says already installed and done one installs x 300 driver on 6 ttimes own.

  I know it must be something simple that I'm missing. My system is the Inspiron 9300 with 2 GB of ram and the mobility x 300 card.  Any help would be appreciated.

• Screen saver turns on and the keyboard or the mouse you want to start over.

  I bought a HP Pavilion desktop computer PC p6-2016 and started to use December 10, 2011. It goes into screen save mode and won't wake up. The HP screen comes without office or on what I was working on. Some time it turns on and does not display Desktop. I have you turn off and on again (2 or 3 times) to operate. Help!

  Make sure that you use the blue VGA cable OR white DVI cable to connect your pc to the screen. If both cables are connected, the pc can see the monitor as two different monitors, which can cause the behavior that you are experiencing.

• Screen turns off when the Satellite A45-S250 is moved in the direction of less

  Hello.

  I have a satellite A45-S250. I had no previous problem with this machine. However, when the computer is running too long, or it is moved in the slightest way the screen turns off. I don't even have to type very slowly - or I lose the screen.

  But also, as I have said - sometimes I won't even be near the computer and the screen turns off. When I lose the screen if the light shines on it - I can see, it's always VERY fair Sun. Generally, it will come if I use the FN + F5 button.

  I don't know if it is a screen problem or a connection problem. It occurs with increased frequency. Any suggestion would be appreciated.

  Thank you

• Latitude D610 screen turns off after the Windows XP loading screen

  I'm having a problem with my Latitude D610 where after the Windows XP loading screen, the screen turns off completely. No BSOD, no login screen, just a white screen. This started happening at least a year, however, I bought a new computer if it is passed to the hatch. I tried the system restore when it appeared first without success. The computer starts in Mode safe. Any suggestions?

  If it starts in mode without failure, then its almost certainly a driver and with the blank screen problem, I suspect a display driver.
