Backlight: turn off the device spends in sleep

• Cannot use Wake on LAN, unless that "allow this computer to turn off the device to save power" is checked

  Wake on LAN - power management

  On my Media Center PC, I am unable to use Wake on LAN unless "allow this computer to turn off the device to save power" is checked (in the tab power management of the adapter in the Device Manager). "Allow this device to wake the computer" and 'Allow only a magic packet wake the computer' is checked, but become grayed out when "allow this computer to turn off the device...". ' is not checked.

  The problem is, Wake On Lan doesn't work unless the computer has been asleep for a short period of time. If I try to activate the computer using WOL after about 10 minutes, he never wake. I guess that's because "Allow this computer to turn off the device to save power" is checked, the machine is before turning off the network adapter.

  Is it possible to force the computer to disable the NETWORK card, but would retain the capability of WOL? Or ensure you THAT WOL works little regardless of how long the PC has been asleep?

  The machine is a Windows 7 PC with a Nvidia nforce network controller.

  By the way, I have a laptop on the same cable network that has all three items checked in the tab for its NIC device power management, and this machine can be awake at all times using WOL, regardless of how long he has been asleep, this issue must therefore be with the configuration of the Media Center computer.

  I would be really grateful for any suggestion, I spent a lot of time trying to get this to work!

  See you soon

  Hello

  If the systems are only a sleep you don't need a magic packet.

  If computers are set to wake on any network traffic all Ping or arp will wake them up.

  For this configuration, it is best to disable the saving of NIC.

  There may be some variations on where is the energy saving setting.

  Here are a few examples, YMMV, look around your systems.

  12 Desktop who are under my immediate control (mix and match brands and processors). Only three are fully compliant and properly awake.

  Three satisfied partially, the rest don't care my desires/needs of Wake on LAN.

  On the positive side, since it is now fashionable to go green, the percentage of new computers that keep the better sleep habits significantly improved.

• HP Pavilion Notebook 15-p045tx: wireless capability is turned off, the Wi - Fi button on / off Greyed Out

  Hello

  I was faced with this problem for a lot of time.

  The Network Diagnostics, it gives this error:

  WiFi is disabled

  I don't have any hardware button that can wifi device off / turn on my keyboard, see the example image below:

  I never turned off the device physics wifi directly or from the BIOS.

  Tried the "f12" also, airplane Mode which also did not help.

  in any case, I tried on things until now, nothing helps:

  (1) reset BIOS HP using HP Usb Disk

  2) update drivers wireless Broadcom using HP Support Assistant

  (3) re - install the Broadcom drivers

  (4) install the Realtek drivers

  (5) Restroing 8.1 full disk recovery Windows.

  (6) installed Linux (Ubuntu/Fedora), but that also free WiFi does not appear.

  Please guide me what can be the possible cause of this problem.

  The issue seems to be with my wifi chip.

  Eventualy I had to take the laptop to the Service Center. The guy tried everything I did once again.

  Finally, the issue is resolved, he plugged into the smart wifi, cleaned both ends, a little with the help of an eraser and reinserted and voila, it has detected. He said it could be the issue of carbon deposited on the ends of the chip connection.

  Since then, I've encountered same question several times, and everything I do is open my laptop, plug out a smart WiFi card mother, clean up a bit and plug it again.

  And he started working like a charm.

  Maybe it is loose or I don't know what the exact problem is.

  But he still has a problem with the antenna, I get very low my wifi signal, even if I'm in the right range of wifi router.

• I have a DELL Inspiron 6400 running Windows Vista. The backlight turns off.

  I have a DELL Inspiron 6400 running Windows Vista. The backlight turns off when the charger is plugged after about 10 to 15 minutes. If I shine a torch on the screen, I see about the display is always. If I select change user from the menu start or stop / restart the machine, the backlight turns on and will last for another 10 to 15 minutes. I tried in safe mode and the same thing happens. Can someone help me with this problem?

  It could be the inverter Board or the backlight itself on the way to the outside. Whatever it is, it is definitely a hardware problem and it will take a good repairman to fix. You can contact Dell and see what they would charge to fix this, just to see if it would be more cost-effective to buy a new laptop or have it repaired. Because it is 5 years since it is manufacturing, you can be better to save your pennies for a new :-(
