Screen works only after a hard reset.

Hello.

I got this dv6220la of Pavilion with a strange screen problem.

In normal use, the screen never lights up, all lights come on, I see the drive hard drives work, but completely black screen, not even the backlight remains on.

If I keep the power button until the laptop turns off and then turn it on, while the screen works normally.

Whenever I turn it off normally (press the power button or use the stop dialog box) will not work after turning on the screen and whenever I have the strength it will work normally until the next power off.

What could happen?

----------

When something does not work as it is supposed to, then it works as expected.

You have to love how useful HP support forums are always =)

  • Pavilion dv7t-3000 mobile: stuck on the startup screen, must repeatedly perform a hard reset to fix

    When starting after a successful boot & use, the PC is stuck on the startup screen that is black with the logo blue & white HP in the middle and "press ESC for the start menu" at the bottom left. I have to perform a hard reset to get a normal startup. Everything works fine. I stop the PC from the start menu. At the next startup the PC hangs at the HP splash screen.

  • B590 - Main screen works only with Windows 10

    Hello.

    I have just updated to Windows 10. The first time he start it worked fine, but now the main screen does not work. During start up I see the Lenovo logo on the main screen, after that the screen goes black. The external screen works. It seems that Windows does not detect the main screen, because the Device Manager shows only 1 screen (external)! have disconnected the external screen and I made a screenshot, then some screens are shown on the Device Manager:

    Hi spidey101.

    Thanks for responding.

    It is not an arrow icon to the bottom, the icon is an icon of the Board of Directors.

    In any case I just solved it. I don't know exactly how I did it. I restarted many times, I changed the resolution of the screen for all possible modes, I tested all dual screen modes (mirror, expand, only external,...), I started in safe mode,... In the end, I unplugged everything, I removed the battery, and now it works

    I want to just synchronize the pieces needed to run my t / x. I want to remove the program, I think it's not let run.

    Act as if you upgrade:

    -hard reset
    -Locate the backup under Palm Desktop folder folder
    -Rename in backup_old
    -synchronization, select old id. This will bring back PIMs (calendar, Contacts, tasks and Memos) but no settings or programs
    -Reinstall the applications one by one AFTER having checked that they are compatible with the device target.

  • Bluetooth works only after restart

    I got my new iMac a few months ago, and since then, I had this annoying problem.
    My bluetooth mouse and keyboard don't work after a reboot, in fact all bluetooth doesn't work after reboot.

    When I start my computer and connect with a second mouse and plugged in the bluetooth keyboard is "not found" and there is not in the system of care either in bluetooth. But I googled and tried different things and makes the SMC reset and after restarting the bluetooth is rising and running after the connection...

    Do I need to restart my computer everytime I want to use it?

    Hi Anna,.

    You have an imac 27 "?

    I bought a new one and spent a total of more than 20 hours on the phone to apple care. After a month, I return two different imacs and am now on the third.

    After giving me bad suggestions a month, apple now care, it is true, now, not a month before, tell me that they have discovered a 'known problem' by which the new iMac 27 "with some configurations loses their bluetooth connectivity if an update of the BONE is made up of el capitan!  I don't see any other product you would have a problem with, even if you bought it new.

  • PC laptop Envy 17: Envy 17 laptop PC fingerprint reader works only after the start

    The fingerprint on my Envy 17 reader reads only a fingerprint the first time that I connect once the system is booted (after shutdown or restart). From time to time, it will read once the system is locked, but that is extremely rare. I put the system in place using my MSN account and also configured SimplePass with default settings. SimplePass version is 8.00.57.

    I looked on several other issues in the forum and did not find something like this. Other issues reported when related to player doesn't work do not, for example. I found a few link in some messages describing such tasks that go back to a previous version of SimplePass.

    I don't know if it is related to my problem or not, but I noticed that the drive light sometimes flashes a sequence once the system is running. It seems that when the light flashes, it will not be read. It stops flashing when I placed my finger on the reader. (I think that the typical sequence is 3 flashes, pause, 1 flash. This cycle repeats.) This isn't always for that well, and I have found no correlation between the flashes and the measures taken after the initial logon.

    I made the fingerprint reader driver, rather than later.

    I uninstalled SimplePass (after update to the last with no luck) and the drive works fine now. I use RoboForm for my password management and it supports using the fingerprint so I'm covered there. I guess it should be renamed "SimplyNoPass."

  • USB works only with different HARD drive...

    Both are Acer Aspire laptops. We have AMD, another, intel. AMD, one died, leaving behind my harddrive perfectly well with all my stuff on this subject. The intel we get my hard drive (from AMD). This works. Only problem: USB ports do not work. Not at all. If I look in Device Manager... There is a label of warning exclaimation on my video display (error code 12. Yet there are a lot of free resources)... and a crapload of all listed Universal Serial Bus ports, with this warning symbol but error code 37. I've exhausted all options on how to 'fix' my problem... but a little problem... I have not met my problem as a whole. Everyone elses problems comes from everywhere to connect to a device USB so he can stop working until an update of windows did. There should be no problem, but it is a. Oh yes, windows 7 x 64 is the operating system. I downloaded and installed all the drivers Acer, except amd... hmm... looking up for this portable body and mind (hdd) that he is supposed to have... idea k. In the meantime, someone knows what to do?

    My old acer aspire has a 5538 (AMD)... new is a 5734z (intel).

    Guess I'll go back to acer.com and download drivers for the old laptop, see if windows will then expose to correct things.

    Hello

    Your post is confusing.

    You trying to start in and use the hard disk and the operating system out of the device in a more recent machine broken?

    If so, you cannot legally install and boot into hard drives and their operating systems that have been transferred to another machine, unless you are licensed by the retail, which would require a reinstall anyway for the reasons listed below in my response.

    The two Acers have preinstalled OEM licenses of operating system on them and these licenses are tied to the original machine and are not transferable.

    .

    And the hard drive that came out the breakage of the machine has drivers for the motherboard, etc of the broken machine, not the newer machine.

    So you will be naturally enough have problems of recognition of hardware, including USB controllers, etc.

    And don't you can't change drivers in the old hard drive and the old operating system.

    I suggest that you save your data from the old hard drive and then use it to store data in the newer machine.

    See you soon.

    The person who took my hard drive works perfectly on my old laptop and put it in my new body of laptop is a licensed computer technology. He thought that it should not be a problem even if the chip inside the new case was a pentium from intel.

    He installed all the drivers for the new motherboard laptop on my hard drive. But, the 'graphics card' intel (R) 4 series express chipset family had an error code 12 'lack of resources to operate this view"in Device Manager. And my USB ports do not work, gives error 37 and not all record as that of operation. So I could not use my USB stick for school work done. I got in touch with him. He took my hard drive out and placed a hard drive for acer with processor intel pentium. If it was not so urgent for me to need my computer... I would expect it 3.5 more weeks for an amd processor chipset 'inside' body (case of the motherboard).

    So... now my 'problem' is 'solved' regarding my question went.

  • BlackBerry Smartphones BBM w / WiFi works only after changing SIM card not

    Hello

    I need help (otherwise I would not write here). I have the Bold 9930. Until I left the States, my phone was working perfectly fine... I had an email, BBM, whatsapp, text, etc...

    When I arrived in Haiti, I wanted to change my SIM card, then I would be able to use / have a number of Haitian. I don't have an international plan. When the guy put my the Haitian SIM, the phone asked my BlackBerry ID and password. I typed all the two, which were both correct, but he told me that it was a wrong password. The guy told me that the only way I'd be able to 'reset' from my BlackBerry ID would be to disconnect and to do this, it would eliminate all my pictures and everything. I didn't do that so I ended up buying a Haitian phone w / a Haitian SIM card.

    At this point, I have two phones. An American with a SIM American (BlackBerry) and a Haitian phone with a SIM card that is Haitian.

    When I got home, I turned on my American phone and its WiFi, but my BBM and emails were NOT WORKING! However, my Facebook application and the browser are both works perfectly well.

    I restarted my phone several times since yesterday and nothing has changed. I checked this morning to see if it worked, but not luck.

    So my question (s) / issue (s) is now:

    1. How can I get my BBM works again? (probably the most important)

    2. How can I get my email working again?

    3. is it possible possible for me to have my BlackBerry (US phone) work with my Haitian SIM card?

    Please, please, please, help.

    Unfortunately, the device works as expected. Facebook, the wifi browser work fine on wifi but BBM and email REQUIRE a valid BlackBerry data Plan.

    The only way to make it work is to have a BlackBerry data Plan on the Haitian Sim Card.

  • Linksys WRT1900 AC comments account login screen works only on certain Android tablets

    I have the Linksys WRT1900 AC and always try to find problems with the existing material. For some reason, almost half of my Android tablets do work well with the guest accounts. For example, the Tablet sees the guest account of Linksys and links, however, I never see the login screen to enter the password "guest" in my setup, in fact, send and receive data. I'd rather do not yet have a password on the guest account, but when I tried that in the Linksys configuration it wouldn't let me have no password. So, I'm trying to find how to force the login screen appears to enter the password "guest" to complete the process to send/receive data.

    I don't know if the problem is with the tablets, Android, the browser of the Tablet, or some other problem. Since each niece and nephew shows up with 2 or more phones and devices, I really want to understand why some show the login screen, and others do not (but reported 'connected'). Any help appreciated.

    @gtaus

    Open a browser and access the internet so the login screen will come out. If the devices does not connect, try forgetting the network, and then connect again. There is no way to remove the password for the network of comments, it's for your own safety. To understand how network invited, click on the links below:

  • Acer 1810TZ webcam works only after the new installation of Windows 7

    My hard drive died so I don't have access to the recovery partition. I did a fresh install of Windows 7 on a new drive.  Everything works except the webcam.  Windows has recognized and installed the drivers (and works) but nothing can connect to it.  It was working before the accident (also W7).

    The Acer website says it is made by Chicony (is ID 0 c 45 6310 suggests Sonix) so I downloaded and installed the drivers installed and appropriate Acer Crystal Eye, but it crashes at startup without error message.  Skype and other applications cannot connect to the camera webcam.  I also tried all the other drivers on the Acer website, just in case.

    Comparability Windows Center suggests that the pilot was developed by Suyin that might be the problem.  I found some Sonix drivers that will install on the Microsoft ones but make no difference.  I tried to install and Crystal Eye running in compatibility mode.

    Any ideas how to solve this problem?  I am now at a total loss.

    Help much appreciated. Thank you.

    Hi Shalini

    Thanks for getting back to me.

    I am running 64 bit.

    Yes, the webcam is detected under as WebCam imaging devices.

    Drivers been uninstalled (reboot) and re-installed (reboot)

    Webcam programs have been removed (CrystalEye & Skype)

    I downloaded for a Chicony (WebCam_Chicony (AP) _1.1.95.71_Win7x86x64) drivers as Acer judged my Chicony camera Suyin not

    I heard support from Acer, who say that the problem is caused by a difference between OEM and sales at retail of Windows 7 and I need to re - install Windows from the recovery DVD.  I prefer not to do that.

    Thank you

  • External keyboard works only after the restart with Port Replicator III Plus

    The problem is that when I start the laptop, the external PS/2 keyboard does not work. When I reboot keyboard this one turns around and then I can use it.

    This problem occurs on a laptop Toshiba Tecra with an Advanced Port Replicator III Plus. I used several keyboards, so this isn't the problem. I changed a value in the bios which is used for devices USB (mouse/keyboard). I disabled the option, because I use a keyboard and a PS/2 mouse, but the problem is not resolved. I hope someone has an answer to this problem.

    Hello

    It will be interesting to know what model Tecra you use. Is it perhaps Tecra A6?

  • Smartphones from blackBerry 8350i eception exception java.lang.NullPointerException after hard reset

    basic information:

    8350i

    v4.6.1.204 (Platform 3.0.0.73)

    Desktop Manager 4.7

    everything is good except that I was using two batteries, one in the phone and the other in a charger. When the battery is almost empty I swap with one charge naturally causing a hard reset.

    This procedure worked well for at least a week or two, until last month when I swapped batteries - after the hard reset, I had

    Eception exception: java.lang.NullPointerException

    I could make calls, but all other software were corrupted... practically nothing else worked... missing icons etc.

    tried all kinds of solutions, but the only thing that fixed it was a full-on device software erase/recharging, then a restore of data since the previous backup. at the time, I thought it was just something random and was happy to learn how to do a full charge of the software.

    then yesterday it happened again (even once, at the end of the security check immediately after the hard reset). now I'm afraid to swap batteries because it seems that every time I have hard reset it recharge a 10% chance (I guess) of corruption of software and a complete takes considerable time.

    If anyone else has noticed this? does anyone have a solution?

    can I change batteries without a hard reset; i.e. Exchange while that connected to the power supply? I have not tried this yet for fear of harming my BB.

    any help is appreciated,

    John d.

    15 seconds is too short period of time.

    It took at least a minute before returning the battery.

    Error you reported is related to badly written in device memory operating data.

    In most cases, helps to battery pull. But you must wait at least one minute before you put the battery on the device.

    When you do battery pull make sure that this device is not connected to any external device or the wall charger.

    In the event of battery pull does not help, I recommend to consider wiping the device memory.
