EliteBook 8740w thinks that the lid is closed, but it is open?

Hello

I have an EliteBook 8740w running Windows 7 64 bit and I have a strange problem where the laptop seems to think that the cover is closed when it is open.

If the cover is open, the screen is off the touchpad and keyboard, the two do not work and not the function of the buttons volume or wifi. When the screen is almost completely closed the screen turns back on, the keyboard and the mouse are beginning to work again, but it is not usable, because it is about 5 degrees, far from fully closed.

It seems that it is just reverse how it is supposed to work?

All this happened when I unplugged my power cord. The screen turned white and it has been in place since then. I tried several reboots, nothing seems to recover.

I can run on my external monitor very well, so the laptop seems to be otherwise functional

Thanks in advance for any ideas

Maybe you did not reset properly.

Remove the battery and adapter and all the things connected to the laptop.

Hold the power button down for 1 full minute and only plug the adapter back to (do not insert the battery) and start.

The next time you stop everything, install the battery.

  • Laptop will not go to sleep when the lid is closed

    Separated from this thread.

    Same problem here. My settings say that my Toshiba will sleep when the lid is closed, but half the time is not asleep and I can feel it's hot and turns on the fan. I am so frustrated with this new laptop and Windows 8.1. Looks like too many bugs in the software or something. More I am working on the new laptop the more problems that I find, like screen discoloration as well. The forums are useless. I do what they say, and the problem is the same. Forget the call from Toshiba. Needless. Nobody will help unless you pay them money to subscribe. What customer service?

    Hello

    Thanks for posting your concern here at the Microsoft Community forum. Let me help you with your concern.

    This problem may occur because of any change in power on your laptop options. If the default is set to hibernation and standby modes, your laptop goes to sleep when you close the lid, but then the Hibernate timer comes in and wake up your computer first and trying to Hibernate. He cannot go to Hibernate directly from mode 'sleep'. Go into the power settings and either disable hibernation or set the timer on a higher value.

    To apply the same setting to all plans:

    1. Open Power Options by pressing the Windows key + X, clicking Control Panel, click system and security, and then clicking Power Options.
    2. On the Select a power plan page, click choose the cover.
    3. On the page define power buttons and turn on password protection , next to when I close the lid, choose what you want your laptop to do, both when it is running on battery and when it's plugged in.
    4. Click on save changes.

    Tip: To save battery power and quickly resume working, select sleep. Sleep is a power saving state that allows a computer quickly resume the operation of full power (usually in seconds) when you want to start working again.

    To apply a setting to a specific regime:

    1. Open Power Options by pressing the Windows key + X, clicking Control Panel, click system and security, and then clicking Power Options.
    2. On the Select a power plan page, click change plan settings for the plan you want to change.
    3. On the change settings for the plan page, click change advanced power settings.
    4. Advanced settings tab, expand it cover and the Power button, action lid, choose what you want your mobile PC to do when you close the lid, for when it runs on battery and when it is plugged in, and then click OK.

    I hope this helps. If you need help with Windows, let us know and will be happy to help you.

  • Dv6 7000: charging does that when the lid is closed (sleep mode)

    I have a laptop HP DV6 7000. The battery doesn't work that when the lid is closed (sleep mode).

    If I close the lid and plug in the charger, the light indicates orange and the battery will deliver to load almost full.

    If I open the lid before the orange light changing to white, battery icon always says: _ % available (plugged in, does not support).

    Several different Chargers give identical results. EACH of them is fully charge the battery in two hours; as long as the cover is closed. If I open the lid, even to say 50% load, the orange light glows white and the battery icon always says: _ % available (plugged in, does not support).

    Thank you, Ed.

    Hi @ElyMayor

    Thank you for your response.

    The last thing I can suggest to try a restore to factory.  Performing a recovery of system HP (Windows 7)

    While the recovery, there is an option to backup your personal files. If you have not already done so, it is now a good time.

    Restore files that have been supported to the top using HP Recovery Manager (Windows 7)

    Alternatively, you can contact HP support for assistance. They can access your system remotely to help alleviate the difficulties.

  • NB250 makes scream sound when the lid is closed

    Hi all

    I am facing this problem with my laptop NB250.

    Steps to reproduce the problem
    i. internal microphone and speakers are enabled
    II. play some audio.
    III. close the lid while the audio is playing.
    IV. when the lid is closed (or even when she is brought very close to the keyboard) there is a loud noise.

    I went to the shop where I bought the laptop. The technician he said that this sound is done because the microphone is taken directly above the enclosure when the lid is closed.
    But I do not think that the sound must be made when the lid is closed.

    I should be grateful if the following queries are processed:
    i. This is a problem with only with NB250?
    II. is it a common problem with all laptops that have the speakers placed next to the touchpad, which brings the microphone from the speakers when the lid is closed?
    III. If there is a problem with my laptop, what should I do to repair/replace?

    Thank you
    Yogesh

    Hi mate

    I think you're talking about the sound looping between speaker <->microphone.
    I n t have this model laptop but I found an interesting How TO from Toshiba on similar topic. It addresses s L500 series.

    Check this box:
    + Hissing sound +.

    Disable the microphone volume in the speakers properties and this will help you get rid of these sounds.

  • Dell XPS 13 lights up once the lid is closed and put to sleep

    I have a strange problem. I noticed that when I close my XPS 13, it stops (as indicated by the boring before LED) but then later it will start up while it is transported. Sometimes I'll get home, get out of the computer case, and it will be as hot as a heat missile because it worked.

    I don't know why it would boot only randomly like that? I have power options 'sleep' when the lid is closed, as shown here: http://i.imgur.com/p0x1C86.png.

    I don't think I have malware because I reset my computer to factory several times and scanned with SpyBot and Windows Defender settings.

    In the Bios "Wake on LAN" is disabled.

    For the life of me I don't see what would be the trigger that the NSA (just kidding). It happens to someone else? Did you find a solution for this? Was it a dell program? Or is there a defective piece of hardware on this computer?

    Any comments/suggestions would be appreciated. Thanks :)

    I could solve this problem by installing a clean version of Windows 10. I have an MSDN account so I downloaded the ISO from there and everything removed from the hard drive before reinstalling Windows 10. The only problem I encountered is that I wasn't able to install UEFI mode. After you have installed all the drivers for Dell, laptop can accommodate properly and autonomy is great. There must be a problem with software that installs Dell with Windows that is the cause of the sleep problem.

  • Speakers satellite Z830 - 10 M is turned off when the lid is closed

    I'm running a Z830 - 10 M with an external monitor. I want to close the lid of the portable computer, but use the internal speakers, but when I close the lid, the speakers will cease to resound!

    How can I fix it?

    Thank you.

    I guess that your laptop goes into mode standby when the lid is closed.
    Right?

    In this case, you must set the option to choose what closing the lid does nothing to

    This can be found in the control panel-> Power Options-> in the left column

  • Satellite don't wake up from sleep or hibernation when the lid is closed

    It is a problem that I had with my laptop from the outset - if the laptop is in sleep or Hibernate mode and the lid is closed, or the lid is closed and will switch "standby" from there, it won't wake up or respond to the switch once again opened.

    Even holding down the power button has no effect, the only way to turn it back on is to remove the battery, put it back and turn the phone back on, lose anything I had opened.

    I fear that the laptop could be damaged by this, but there is no other way.
    This isn't a problem with the settings of windows, I had the same problem with the function suspends in ubuntu.

    Anyone had similar problems or know anything than either could have caused this?

    What model of Satellite L do you have exactly?
    What system is pre-installed? Have you tested this problem with laptop recovery fees?

    BIOS is up to date? If it is not updated in the BIOS.
    After update BIOS, set the default BIOS and test the features of the laptop.

  • Satellite U - Vista starts when the lid is closed

    Hello

    The title says it all!

    My girlfriend showed me her cell phone yesterday. She manually stop it on the start menu, leave for a few minutes, close the lid, then watches in joy as the computer laptop Springs revive again.

    I checked and the judgment indeed makes a stop, not a hibernation or something like that. I also changed the lid closed to "nothing" action and "stop" and I tried various methods to stop this strange behavior. My only solution was to have vista recognize the lid close like a stop action and have this control by turning off the laptop. Unfortunately, my girlfriend is a woman of routine and like to manually turn off the laptop before closing the lid, so my solution is not a long-term one.

    One thing that I've seen is that she had managed to install Uniblue Registry Booster. I quickly removed it, but wonder if it could have changed his behaviour of the laptop? Surely the fact if boots up when it is turned off when the lid is closed could not be attributed to Vista or whatever it is that was done for her?

    Thank you

  • Satellite L10-187 wakes up when the lid is closed

    I got this Toshiba Satellite L10-187 for a few years now, and since I bought it I had problems with it to wake up even if the lid is closed.
    Suspended or hibernation is not serious, he always wakes.

    More annoying is when I have it in my backpack and I noticed that the battery has been drained, when I want to use the computer.

    Is this a known issue?

    Hello

    L10 is old enough laptop model and if you noticed from the first day, I wonder why you waited so long time and didn't search for solution before. In any case, enter the BIOS settings and disable Wake up on LAN option. As far as I know wake up the system can also be result of active Windows update Service. Disable it.

    Please disable both options and report us what happens now.

    I can't say much on battery. Just a question: is the battery just when the laptop is in sleep/hibernation mode or this will happen even if the laptop is turned OFF?

  • I can do: sleep when the lid is closed, EXCEPT when an external display is connected?

    Hello

    Please let me know if this is possible. Seems to me like a current need, but I can't find a way to achieve this.

    I wish that the laptop to sleep when I close the lid (battery / plugged - matter), except when I have a connected external display.

    The script is very simple, I prefer to work with an external display, so I don't want or need the lid is open. When I'm on the road, the "sleep when the lid is closed" is a desired behavior.

    Is this possible?

    Thank you

    Roee.

    (1) this function is available in the Apple OS, but not in OS Win.

    (2) but, you can set a custom power plan to do this, so when you connect an external monitor just switch the power around plan. It is the easiest way to get what you want.

  • Computer user connection laptop turns off when the lid is closed

    How can I configure my laptop to disconnect the current user (switch not only users) and force them to close all programs when the lid is closed, and then switch to sleep mode?

    There is no direct option for this, but you can create a batch file that has orders for logoff, then the command for the night and have that run the trigger of "Lock Workstation".

    Task Scheduler allows many triggers.  Type Task Scheduler in your Start menu, and then click New task on the right side to explore your options.
  • Inspiron 17R SE 7720 wake from its slumber when the lid is closed through the usb keyboard/mouse

    So I have an Inspiron 17R SE 7720 which has all of the latest drivers with BIOS A11 (Win 7 Ultimate x 64)...  I have all the settings properly configured for sleep power (no hibernation), however no matter what I try, I can't get the laptop to wake up when the lid is closed through USB keyboard.

    I use a combo of MK560 Wave from Logitech (unifying receiver) - keyboard and mouse have the wake-up option enabled in the settings of their material.  I also wake up from USB enabled in the BIOS.

    What is interesting is that if I put the computer to sleep with the lid open, I can do/wake it from Logitech devices.  With the lid closed, I can only do sleep - the only way to wake up, he is to open the cover and press the power button.

    Anyone know a solution to this?

    Cliffs Notes:

    Cover open: CAN sleep/wake from USB keyboard/mouse

    Cover closed: can sleep ONLY - don't wake up if I open the Start button / cover & press

    It seems that a new A13 BIOS was released on 18 March, all it says in the section '' correction '' is to "maintain the release." Download it now and see if it fixed more on the question of the USB.

  • T410 connection when the lid is closed

    I am portable computers T410 deployment to the field, but users report the network connection drops when they close the lid.  I checked that the PC is not in standby mode.  I have the settings of Thinkvantage Power Manager to do nothing when the lid is closed and allowed InstantResume to stay online for the max of 99 minutes, but which is not helping.  I still adjusted power profile settings to not go to sleep for an hour while on battery.  Laptops running Windows XP Pro x 86.  Any help would be appreciated.

    It turns out that the issue was a question of power settings.  Disabling the sleep settings and disabling sleep by closing the lid solves this problem.
